4/1/2020

1 Comment

 
​On the main highway south of Tulum in Mexico there’s a beautiful little cave system called Sistema Hatzutz Actun.
About the cave:
  • colourful - lots of gold formations
  • beautiful formations, highly decorated rooms
  • great fossils - molluscs, sponges
  • halocline at 20 metres
  • maximum depth 23.5 metres
  • still contains original exploration markers
  • blind cavefish, remipedes
  • mainline passable on backmount
  • sidemount recommended for many passages, multiple restrictions
  • line tension isn’t great in some sections, take care in the halocline
  • decompression may be required
  • insufficient length to warrant DPVs
  • no cavern diving

Directions to get there:

Highway 307, south of Tulum. The Zero Gravity Dive Centre has Cenote Hatzutz Aktun as KM 47.5 from the shop (there’s variability between cars, my odometer read 46.9 km). It’s 1.7 km south of Cenote Cristal (Naharon), on the same side of the road (right, as travelling south from Tulum). The stone entrance has a small red dive flag and a decorative iron gate that will be open.

Don’t be fooled by the pool of water on the left about 100 metres in. Keep driving past the buildings, strings of flags and horse corral, the cenote is 300 metres in. Look out for all the cats and dogs as you drive through.
This is NOT Cenote Hatzutz Aktun.
This is NOT your dive site. Keep driving.

Dive site information:

Entry fee for cave divers:

MX$250 per diver (February 2020). The landowner’s employees will come and find you at the cenote to collect money and get you to fill out the dive log book.

Locating the line:

The cave line comes to open water. It’s located on the cenote floor a bit out from the end of the platform. It will be easy to find if the cenote water is clear (in December) but may be more difficult if the water is green. The cave entrance isn’t very high (top to bottom). There’s room at 6 metres to drop O2 tanks (if required).

This cenote has been modified. Expect a heavy silt load inside the cave entrance.

Depth:

The maximum depth for the cave is listed on the map as 23.5 metres. The halocline is at 20 metres.

Facilities:

There is a brown painted cement toilet block with 2 toilets. Head back up the path towards the road, on your right. I don't like to ever assume there will be toilet paper!

​There are no benches near the carpark for twinset divers. There is a nice wall you can stand your doubles on to get them on easily.

There’s a nice cave map at the site drawn by Nadia Berni (2017).

Stick map:

*Map not to be used for navigational purposes. Why not? Because lines change, navigational markers change, cave exploration may continue and nobody's life should depend on a hand-drawn map they found on the internet. Please take care navigating while cave diving and reference the cave as you find it in the water.

The problem with plastic

9/7/2017

4 Comments

 
Plastic items collected from a cave in Mexico
I think we all understand the problem with plastic. Many of the disposable plastic items we use in everyday life are made from a material that lasts forever. These items don’t break down, they break up, into smaller and smaller pieces.

Plastic is ending up in our oceans and our marine life. It’s finding its way into the food chain and the fish we like to eat. Much to my horror, I have discovered that plastic is finding its way into caves too.

I recently spent a couple of months cave diving in Mexico. The Yucatan Peninsula is a mecca for cave divers. Hundreds of kilometres of underwater caves connect hundreds of cenotes. The underground aquifer is amazing and I feel fortunate to have had this amazing experience.

The water in the caves is often crystal clear. People comment on my underwater photos “is there even water in there?” Swimming through the cave, you can imagine you’re swimming in a pristine environment. It may be an illusion though. Human activity on the land above the cave systems means that the water isn’t drinkable without treatment. Ear infections are common.
Cave diver downstream from Cenote Nohoch Nah Chich in Mexico
On the last day of my trip I went for one final cave dive. I drove to the spectacular Cenote Nohoch Nah Chich. Nohoch is a very popular cave diving site. It has shallow tunnels decorated with elaborate white formations. The clarity of the water is breathtaking. Most cave divers head upstream and I usually do too.

This time I decided to go downstream. The downstream cave has a different feel. The silty floor is darker from organic material washing into the cave. The cave is punctuated with air domes. White columns clash with the dark floor. It’s beautiful. It’s also contaminated with plastic.

Passing by an air dome, a flash of vibrant pink grabbed my attention. Playing my light across the water’s surface, I could see brightly coloured objects floating. They were caught up with crystalline calcite rafting and buoyant seed pods (both natural features). At first glance there were plastic bottle caps and those bottle security ties that you rip off a sealed water bottle before you guzzle it. There were brightly coloured objects I couldn’t immediately identify, except to say that it all looked like plastic.

I kept diving but I couldn’t get my mind off the rubbish. I wasn’t about to leave it in the cave. On the way out I signalled my team mate Cameron, who is also my spouse. I asked him to join me and help me grab what floating plastic we could from the air dome. He wasn’t particularly happy about it, which I could understand. What cave diver wants their last memory of a great trip to be of collecting garbage?
Cave diver collecting plastic garbage from a cave in Mexico
We collected as much plastic as we could stuff into our drysuit zipper pockets. This was a challenge; each time the zipper was opened buoyant fragments attempted an escape towards the cave ceiling. Cameron found a plastic bottle with a cap. He was able to wedge this full of other plastic fragments for easy transport out of the cave.

It was a miserable job. Not the collecting of the plastic. Simply seeing all this waste from human activity messing up a natural environment.

I wondered… where is all the plastic coming from? Cenote Nohoch Nah Chich is a popular tourist site. Snorkellers make up most of the traffic. The cenote has a generous cavern zone where you can snorkel into the overhang. Perhaps those swimmers have plastic items in their pockets: chapsticks, hand sanitiser, pens and chocolate wrappers.

I also collected twenty brightly-coloured plastic loops in the shape of springs. They looked like some kind of bangle. This fashion trend completely passed me by and they surely don’t belong in the cave.
Cave diver collecting plastic bangles from a cave in Mexico
What can we do about this insidious plastic invasion? We can choose to refuse plastic wherever possible. Refill your water bottle from a trusted source every day instead of buying bottled water. Plastic bottle caps (from water and sodas) were the most abundant item recovered from the cave.

We can all pick up litter even if it’s not our own. This is especially important around water such as the sea or freshwater sites like cenotes and streams. When it rains garbage is transported downhill to the water. It’s easier to keep water clean than clean it up.

We can also spread awareness. There’s a global movement challenging our current thinking around how we use plastic in our lives. Plastic Free July is about motivating people to refuse single-use plastic items and find a way to live without them. There are really easy places to start, such as bringing your own reusable bags to the supermarket for your groceries.

Finding plastic inside an underwater cave was disturbing. We need to take more care of our water. Next time you go for a swim, check your pockets for unsecured items. Please be careful how you dispose of plastic around Mexico’s stunning cenotes. We want them to stay that way. #choosetorefuse

Discovery of a New Zealand pygmy pipehorse

12/2/2017

2 Comments

 
“It sounds like a pygmy pipehorse.” I thought I must have heard him wrong. I knew of sea horses, and pipefish, but a pipehorse – now that was a new one to me!
A pygmy pipehorse Acentronura australe is discovered in New Zealand
​I’ve been scuba diving in New Zealand for over ten years; I’ve spent a lot of hours underwater. You might think that by now I must have just about seen it all. Here’s the thing: I haven’t. Not even close.

I was enjoying a special Northland Waitangi Day in my own tradition - scuba diving. Drifting around underwater, I got to check in with a lot of my favourite fishes: red moki, blue maomao, grey moray, demoiselles and kingfish. I was in my happy place.

The topography of the rocky reef lead me into a gully with a vertical wall on one side. I decided to spend the final minutes of my dive searching for nudibranchs, the colourful sea slugs that bling up the underwater world.
A pair of Clown nudibranchs Ceratosoma amoenum from New Zealand
This is a pair of Clown nudibranchs Ceratosoma amoenum, one of the most common sea slugs from northern New Zealand.
A fine brown silt covered the wall and all of the spiky bryozoans that decorated it. I used my dive light to return the natural colours and concentrate my eye towards anything gaudy. A splash of saturated pink, a jerky movement, and I was immediately fixated on something utterly unexpected. It was small and brightly coloured. It was not a nudibranch. I did a double take. It was a… sea horse.

I tried to take a couple of photos. The sea horse was shy, it turned away from me and my underwater flashes. I wanted to get a good identifying shot because the sea horse didn’t look like any sea horse I’d ever seen in New Zealand before. The bright pink colouration with patches of white, the back tassels, the diminutive size - I’d never seen anything like it. Then I realised there were two!

Where one of the pair was intensely pink-red, the other was brown, mottled and muted. It was all but invisible on the silt-covered wall. I checked my dive computer; I didn’t have much time. My boat skipper Shane from Northland Dive was going to be expecting me back at the boat any minute now. I tried again to get some shots, frustration mounting. Normally I wouldn’t persist with such a shy animal, but this was necessary for identification purposes. All I was getting were some nice photos of the back of their heads!

The next step to solving the mystery of the weird sea horse was to hunt around online for clues and connect with an expert. I remembered seeing a photo from my friend Crispin Middleton from Seacology in the last couple of years, so I went to Facebook. In 2014 a sea horse was trawled from the Northland sea during a NIWA survey of coastal sea life. It was exciting because it could not immediately be identified. It was not the known New Zealand sea horse Hippocampus abdominalis, which meant it might be something new, at least for New Zealand.

Less than one year later a photo of another unusual sea horse was posted on Facebook. The discovery was made by Justin Ricketts and the photo was taken by Kent Ericksen of Oceanblue Adventures at the Poor Knights Islands. The report says there were two animals, tails intertwined – just like my sighting. The photo showed similarities with the photos I had taken, particularly the cup-shaped hump on the head and colour (note colouration can be highly variable and is not necessarily an identifying feature).

I phoned sea horse expert Chris Woods from NIWA. I explained what I had seen and he said it sounded like a pygmy pipehorse. I thought I must have heard him wrong. I knew of sea horses, and pipefish, but a pipehorse – now that was a new one to me! I emailed photos and he came back to me: “your pygmy pipehorse looks very much like Acentronura australe known from one specimen from the Bay of Islands, but as we have very limited knowledge of this group (especially from NZ) pinning it down to species is difficult”.

I have so many questions and very little is clear. Is this species rare, or rarely seen, or both? Clearly this little guy is rocking some killer camouflage – we call it cryptic. To say that this animal could be easily overlooked by divers would be an understatement. To learn more we need all keen underwater eyes on the hunt for this species. Stay tuned...

Can you see both pygmy pipehorses in this photo? They're small, <5 centimetres.

This is a pipefish from New Zealand... not to be confused with a sea horse or a pygmy pipehorse. This animal looks long and slender like a stick. It tends to hover around the kelp rather than hold on with its tail like a sea horse or pipehorse.

Many thanks to Julia Riddle and Shane Housham from Northland Dive who allow me to do the long dive times that make these discoveries possible.

Thanks to Shane Housham for contributing images to assist in the identification of the pygmy pipehorses.

Thanks to Chris Woods from NIWA and Andrew Stewart from Te Papa for their expert opinions on this discovery.

Hell's Bells - the world's weirdest dive site

28/8/2016

Cave diver with Hell's Bells formations in Cenote Zapote in Mexico
Cenote Zapote must be the world’s weirdest dive site. From the surface this enticing orb loaded with crystal clear water and lush plants reveals nothing of the mind-blowing formations called Hell's Bells found within. If you assemble your scuba gear and slip below the surface down the hour glass to a depth of 28 metres, what you see will knock your fins off.

Little is known of the enigma that is Hell’s Bells. How were they formed? Why are they found here? Why is there no other dive site quite like this one? There's only one thing I know for sure... you've got to see it to believe it.
Cave diver with Hell's Bells formations in Cenote Zapote in Mexico
The underwater cavern of Cenote Zapote is much bigger than you might believe from the surface. The entrance shaft pinches in at 21 metres before ballooning out into a spectacular room that undercuts the rock. A thick layer of noxious hydrogen sulphide is found between 35 and 42 metres. Trees from the talus cone (the cone of debris and scree material that has fallen into the cenote) poke up through the cloud.

A lined ring route has been laid through the bell formations and takes you around the perimeter. The depth on the line varies from 28 to 33 metres. There is one T intersection with the stem of the T extending back into the centre of the circle and tied off to a tree.

If you are diving trimix and head below the hydrogen sulphide expect it to be completely dark below (cave training and technical training highly recommended). There is a line that circumnavigates the debris cone. Scientific studies are being performed below the hydrogen sulphide on the skeleton of a sloth. Please respect the investigation by staying well clear and not touching or disturbing anything with fingers or fins.

A small section of cave has been explored.

Getting there:

Cenote Zapote is located west of Puerto Morelos in Mexico's Yucatan Peninsula.
 
Get off the main Cancun-Tulum highway 307 at Puerto Morelos. Travel south on the lane next to the highway and turn right at the road headed inland signposted to Central Vallarta, Hol-Box and Ruta de los Cenotes. Travel 19 kilometres on this road then turn left into a gravel road (big sign post for Zapote Ecopark and Kin-Ha Natural Park).
 
Stay on the main wide gravel road for 6.3 kilometres. At one point you turn left. There are signs along the way for Cenote Zapote and Kin-Ha. At roughly 6.3 kilometres on the gravel road turn left at the big Cenote Zapote sign.
Sign post to Cenote Zapote Ecoparque (Hell's Bells) in Mexico

Dive site information:

Entry fee for scuba divers:
$400 Mexican pesos per person (April 2017) - cash only.

Depth:
The Hell's Bells formations are found at around 28 metres or 90 feet. The line that circumnavigates the formations goes down to 33 metres or 110 feet. The hydrogen sulphide layer starts at about 35 metres or 115 feet.

Facilities:
Very nice bathrooms, open air showers, two platforms for leaping off into Cenote Zapote, small number of car parks next to site.
 
The park also contains Cenote Palmas and Cenote El Abuelo - ziplining, swimming, snorkelling, bicycling and tours available.

Warning:
This dive site is deep and takes you into the overhead environment (and away from direct access to the surface). Some kind of cavern training at a minimum would be sensible, along with a redundant gear configuration and gas planning. Consider 30/30 gas for this site.

People leap off the platform into the water. It's recommended that scuba divers take note of the direction of the far side of the cenote so that you can surface safely away from the platform at the end of your dive.

Map:
The Zero Gravity dive shop has a nice cross-section map of this underwater site on their wall. Drop into their dive centre to take a look. They also hire double tanks and do trimix fills. They are located off the roundabout at Puerto Aventuras.

Photography:

Diving in the footsteps of ancient animals

8/8/2016

1 Comment

 
While many consider the deep ocean to be the last great unexplored frontier on planet Earth, cave divers are quietly travelling kilometres underwater and underground, and returning with extraordinary news. Here is evidence of animal tracks from the floors of a submerged cave system in the eastern Yucatan Peninsula in Mexico. Considering that these caves were inundated with water following the last glacial period, this could make the footprints thousands of years old.

The floor of a submerged cave is dotted with overlapping footprints preserved in solidified mud.
When you cave dive there’s a real sense of exploration and that you’re diving where few have travelled before. Deep inside the beating heart of mother Earth, inside her watery system of veins, cave divers are pushing the boundaries of where we’ve been before and what we know about the mysterious underground.
 
Cave divers Sam Meacham and Alex Alvarez returned from a dive and reported that they had seen what they believed to be footprints in solidified mud on the cave floor; I was skeptical. There was a fair amount of jovial banter and good-natured ribbing between friends. I had to eat my words when Sam produced a GoPro from his pocket and played a video on the tiny screen. He seemed to have something and I was excited.
Footprints underwater in a cave in Mexico may belong to a paca (Agouti paca)
A measuring scale is gently placed adjacent to the footprints. Size is an important criteria in identification of animal remains and prints.
Neatly imprinted in mud as if they walked there only yesterday were 3 and 4-toed pawprints from a small animal. Suspended in water, breathing compressed gas from a scuba tank, you might imagine how startling this would be to a cave diver making a foray into the lightless tunnels. My heart nearly leapt out of my chest the first time I saw the prints.
 
To visit the cave at a time when it was dry enough to have a muddy floor on which to record animal footsteps would be to visit the cave not hundreds of years ago, but thousands. The Mexican caves of the Yucatan Peninsula were dry during the last ice age of the Pleistocene when global sea level was lower. When the glaciers melted they released their trapped water into the ocean and flooded the caves.
The floor of a submerged cave tunnel in Mexico is covered with overlapping footprints preserved in solidified mud.
Ancient footprints discovered underwater in a cave in Mexico may belong to an animal similar to an Agouti paca.
Animal tracks have now been recorded from several different locations within the Sac Actun cave system. I believe that the footprints come from an animal similar to a paca (Agouti paca / Cuniculus paca). The paca is a small terrestrial rodent under three feet long that is mainly nocturnal.
 
In the book Mammals of the Yucatan Peninsula (2009) the paca is described as having “four toes on each forepaw, and five on each hindpaw. Generally, its tracks show only three toes, with non-retractile claws.”1
 
From the number of tracks now recorded, I assume that there was considerable traffic by animals around the cave. While I don’t know what the animals were doing in there, I do know that these were not the only animals to make their way through the tunnels. Skeletal remains of gomphothere, sabertooth cats, giant ground sloths, bears, tapirs and other animals have been documented from inside the cave systems of the area. The most famous remains are those of Naia, a human skeleton found in the submerged collapse chamber of Hoyo Negro and dated to be between 12,000 and 13,000 years old.2
Trails of animal footprints on the floor of an underwater cave in Mexico were discovered by cave divers
Trails of footprints indicate the direction of travel of animals into and out of the cave thousands of years ago when water levels were lower.
Now that I know that we are cave diving in the footsteps of ancient animals I hope that others can also be on the look out for more sites of interest. It would be great to get a scientist involved so that we can all learn more about the history of the caves and their importance to ancient animals of the Yucatan Peninsula. Perhaps we can harness the power of the citizen scientist and form a collaboration between scientists and cave divers, as has already proved to be so successful on the Hoyo Negro Project, the study of a submerged Paleo-Indian site.
 
Deep horizontal cave penetration may not be as sexy as deep ocean exploration. It doesn’t involve submersibles and complex space-age-like gadgetry, and there are few living creatures (monsters of the deep) with which to ignite the public imagination. But locked inside water-filled underground chambers are prehistoric clues to ancient civilisations and if cave divers can be alert to these signs and conscious not to disturb the evidence, we can bring these new discoveries into the light for all to see.

How to avoid percolation?

18/4/2016

6 Comments

 

Avoiding percolation - the enemy of the cave diving underwater photographer.

You might have noticed a change in the style of my cave diving photographs. In the past I have shot more photos of my diving models front/face on. Recently I've shot more of my model’s butt - their delightful rear end. This is likely to continue and I’d like to explain why.
Cave diver passing between formations in a cave in Mexico
With the aid of DPVs (diver propulsion vehicles, also known as scooters) I am now travelling further into caves than ever before. This is amazing because it’s taking me into cave passages I’ve never seen before. New cave = new discoveries. It also brings with it many photographic challenges.

Diving a greater distance into caves means reaching passages that few divers ever get to. In tunnels that have seen very little diver traffic it is quite common to experience a lot of percolation. When exhaled gas hits the ceiling, rock flour and fragments are dislodged and start raining down. This ruins the visibility of the crystal clear water and is a backscatter nightmare.

Percolation means that I have almost no time to fire off my shot before the conditions for photography deteriorate dramatically. Cave passage that sees a lot of diver traffic generally has a lot less percolation as the tunnel has been cleaned by loads of bubbles hitting the ceiling. Percolation needs to be avoided.

Swimming a longer distance into a cave also means that the time to take photos is limited. I can only breathe the gas from the tanks that I can carry. When I’m deep inside a cave the clock is ticking and the pressure to get off some shots before my dive team has to leave is high.

For these reasons I am now introducing more of the butt shot - shooting photos of my partner and model Cameron from behind. This allows me to take photographs on the move as we swim through the cave. Shooting while moving means I can keep ahead of the percolation and photograph through clearer water. I can also fire off more shots in the small amount of time I have before my gas runs out and I have to turn around and head for the exit.

Why shoot underwater caves with a diver model at all?

The greatest challenge of cave diving photography (all photography) is light. In caves I have no natural light to play with; I have to bring my own light sources with me. I shoot with a model in my cave photos for three reasons.
  1. The diver provides a sense of scale for the cave. It allows the viewer to get a feel for how big, or perhaps small, the cave is. With no diver it’s very hard to comprehend how big the features in the photo are - most people are not immediately familiar with caves.
  2. It tells my audience that my photograph was taken underwater. Sometimes I’m shooting through water that is so clear it’s not obvious in the final photo that this is a water-filled cave. I want to take my audience underwater with me - the cave diver sets the scene.
  3. My model is a mobile source of light. My diving team carry strobes (flashes) which are fired remotely from my camera. By moving my model I can change how I light up the scene and create depth in my image. This is one of the best ways to shoot and be sensitive to the pristine nature of the cave environment. An alternative would be to place strobes around the cave, but it’s very difficult to place anything on a cave floor without leaving some kind of mark in the silt. An unmarked silt floor is one of the most beautiful things we can leave behind us when we depart the cave. Take only photos, leave only bubbles.
Cave comparison, with a cave diving model and without
Left: cave photo taken without a cave diver model. Right: cave photo plus model. See the backscatter (snow) in the bottom right? This is what happens when I sit still for too long and percolation builds up. Adjusting strobe angles can improve this.
There's no question that people respond to photos of people. I am well aware that the front-on face shot is a crowd favourite. My cave diving partner Cameron has a nice bum, but his face is even nicer. :-)

This change in my shooting style reflects the adaptations I am making to try to capture photos of underwater caves that may not have been photographed much, if at all, before. New cave means new challenges and trialling new techniques to improve on my underwater photography.

14 tips for underwater photography in surgy conditions

4/3/2016

8 Comments

 
A swell is rolling. The sea is a tumultuous mess. You know that the environment for underwater photography is going to be surgy as hell. What techniques can you call on when conditions crap out? Here are the methods I use to shoot great photos in surgy water.
Leopard anemone at the Poor Knights Islands
In a perfect world there’s nothing but calm seas, infinite visibility and water of the purest blue hue. Every underwater photo you take is a winner. If you live in that world you are one lucky sod!
 
The New Zealand that I call home is wonderful, but far from perfect. Sea conditions are widely variable and sometimes borderline undiveable. If I hung out waiting for perfect conditions it would be a long drink between dives. Instead I’ve worked on some ways to cope with the surge and still capture some nice pictures.

Macro or wide angle?
 
If you’re shooting with a camera that has interchangeable lenses then you’ve got a decision to make: macro or wide angle? This is a tough one. No matter what you choose it will feel wrong the second you splash into the water. Make a call and make it work.
 
In my experience surgy conditions generally cause a reduction in visibility. All that thrashing water stirs up sediment and fills the water column with particles. It’s a backscatter nightmare. For this reason I lean away from wide angle towards macro.
 
Say you pick macro - imagine trying to photograph a button in a washing machine. Shooting small subjects in surgy conditions is enough to make any hardy underwater photographer sob with frustration. I guess you’d say I like a challenge.

Location, location, location

Start popping those seasick tablets like they’re party pills – you’re heading offshore. Reefs and islands accessible by boat will have better visibility than shallow beach-access sites where the sandy bottom is stirred up.

On a typical photographic dive in good conditions I look for an interesting subject or scene and set out to capture it. Surgy conditions demand an alternative approach. I try to find a good location in which to shoot, and then search for an interesting subject within it to focus my efforts on. I may spend the majority of my dive in this one location.
 
What makes a good spot? Look for a sheltered site where you can get out of the worst of the wash. A wall that is free of overhang (head and valve-bashing obstacles) with good space so that you can be swept side to side without being impaled is a good place to start. Allow generous space behind for your fins to move - never have they been more important stabilisers than in surgy conditions.
School of Blue maomao at the Poor Knights Islands
You're underwater ready to take photos, now what?
  1. Take a couple of minutes to evaluate the motion of the ocean. Are you being propelled up and down, side to side, forwards and back, or a combination? Surfers learn to read waves. Scuba divers can get a feel for the swell on any given day. Wait for momentary lapses in water movement to fire off your shot. Be ready for the extra big lift that sweeps you off balance.
  2. Look for potential hazards that you may be emphatically tossed upon: rock, reef, spiny urchins, and camouflaged scorpionfish. Avoid those.
  3. Shoot at arm’s length. If you find yourself suddenly propelled forward you have a little extra room to prevent impact. Yank your arms in and hug your camera to your chest. Protect your ports.
  4. Dive with slightly negative buoyancy. Break horizontal trim to roughly thirty-five degrees. Use a gentle upwards kick to hold position against vertical water movement.
  5. Don’t forget you’re negatively buoyant. As soon as you pull back and pause to review your photos you will start to descend - don’t get so caught up in reviewing images that you don’t notice. Keep the reef in your peripheral vision and pay attention to any increasing pressure on your ears. Add a couple of quick bursts of gas to your BC to regain neutral buoyancy.
  6. Consider diving deeper and shoot below the swell. Conditions at 5 metres might be yuck, conditions at 15 metres average, conditions at 25 metres better. Be prepared to adjust your gases and tank capacity to accommodate such a choice. Will you be comfortable holding decompression stops?
  7. Be flexible with composition. It’s tricky to get your elements lined up just right when you’re flying past your subject. Now is a good time to get creative.
  8. Fighting surge is exhausting. Check your pressure gauge more often if your breathing rate is up. Going with the water rather than fighting it is more comfortable for prolonged shooting.
  9. A stem of kelp may seem like a great handle to hold you in position but if you try to fight the movement of the water in this way rather than go with it you can risk being flipped over.
  10. Frustration is finding a great little subject to photograph and then losing it as you’re swept a couple of metres away when a wave passes through. Memorise larger recognisable features around your subject to orientate you in the right spot to relocate it over and over again.
  11. Be patient. The 5 minutes you may need to spend with a subject in good conditions can easily become 25 minutes in bad. Keep calm. Take your time. Review your images. Have you got a shot in focus?
  12. A solid back kick is an essential skill. The ability to move in all directions using your fins leaves your hands free to stabilise your camera and fire off the shot at the critical moment.
  13. It’s nerve wracking placing your expensive underwater camera close to damaging elements when you’re at the mercy of a big sea. But if you don’t get close you won’t get a good image.
  14. Average conditions are no excuse for average skills. No touching is good practice regardless of the situation. Treat the underwater environment with respect.

Unless you live in a perfect world then a good chunk of every year is likely to be spent diving in average situations. While you may not create an award-winning photograph in surgy conditions, this is guaranteed if you stay at home. It is possible to take interesting underwater photographs in the surge if you’re prepared to work at it. Learn to adapt, experiment and above all have fun.
 
The images in this article were taken in sloppy seas with some serious surge.

New Zealand's Sea is Transformed into a Salp Soup

25/11/2015

4 Comments

 
Salps are translucent barrel-shaped animals that may live singly or form colonies metres long. They move through the ocean filtering plankton by pumping water through their gelatinous bodies.

One fine spring day in November in northern New Zealand I descended into a salp soup at the Poor Knights Islands. Salp populations had exploded with the abundance of plant plankton food. This is what I found.

The innocent salps face hostility. Many scuba divers don't appreciate the reduced visibility that comes with the phytoplankton bloom and consequent salp occupation. They're slimy to look at and the touch of a salp brushing bare skin will send a shiver down your spine.

The alien invasion doesn't last long and as quickly as they appeared the salps can be swept away by ocean forces. Before you know it you're missing those crazy plankton hoovering vacuum cleaners and their jaunty jet-propelled motion. Careful... you might develop an appetite for the wonders of our weird wild ocean.

In a press release from Facebook today, the company announced it will be trialling a new range of buttons to complement the famous Like indicator. While the full range of new-fangled emotion emojis is being kept under wraps, Facebook did reveal the first feature from the set, called the 'your post made me feel off-colour ascidian emoji'.

Facebook CEO Mark Zuckerberg explained "we need more sea creatures on Facebook. Sure you’ve got the cute dolphin, whale and fish emojis, but what do these even mean? Our ascidian emoji combines real ocean life with emotion."

Breaking News
August 2015 Publication Released

In February 2015 I reported a 'Remarkable new sea slug find for New Zealand' on my blog. I am happy to update you with the news that Paul Caiger's discovery of Ercolania boodleae in New Zealand has been published in Sportdiving Magazine.

Willan, R.C., Perkins, A.J. & Caiger, P.E. (2015). Boodlea baffles biologists. Sportdiving Magazine 169: 74-76.

Boodlea baffles biologists (Sportdiving Magazine) - sea slug Ercolania boodleae is discovered in New Zealand

The article has been sent to Professor Hamish Spencer for incorporation into the Checklist of the Recent Mollusca Recorded from the New Zealand Exclusive Economic Zone (http://www.molluscs.otago.ac.nz).

The article has also been sent to Lisa Marie, Incursion Investigator with the Ministry for Primary Industries (MPI). MPI is interested in any new-to-New Zealand species - plant, animal or disease. They have staff on duty 24/7 for terrestrial and marine reports. If you ever find a new critter or witness a mass mortality event (e.g. fish stranding), phone MPI on 0800 80 99 66. MPI are happy to check things out and have laboratory facilities for investigating suspected diseases. We don't need any more pests in our marine space.

A risk assessment will be performed on Ercolania boodleae to determine if there is any threat to our environment. Many thanks to Lisa from the Surveillance and Incursion Investigation (Animals and Marine) Team, it's great to know they've got our back.

I'm thrilled that this story has had a happy ending. For a while it looked like finding a place to publish this discovery would allude us and we would have no official record. Dr Richard Willan has done a fantastic job writing up this discovery and securing publication in Sportdiving Magazine. Thank you Richard and Paul!

Found something? To report an suspected exotic disease or pests in animals, plants, fish or bees, call the Ministry for Primary Industries on 0800 80 99 66.
