MV Scuba Adventure North Andaman 19th Feb to 23rd Feb 2014

We were joined by our new customers on MV Scuba Adventure at Chalong and then we headed overnight to the Similans with calm seas. Our check dive was on Anita’s Reef. This is a beautiful sloping reef with pristine white sand that is home to many garden eels and rays. The main feature is the stunning coral pinnacle that is covered in a gorgeous plethora of corals. The trevallies and rainbow runners were in hunting mode as there were so many glassfish. After the dive we headed to Koh Bon were we did two dives on the Reef and the West Ridge. Lovely dives with fantastic visibility, but alas no mantas. However, the marine life was prolific with beautiful schools of five line snappers, golden trevallies, lion fish, mantis shrimps and so much more. We then heard a whale shark had been a spotted at Koh Tachai Pinnacle on the radio, so we headed there for our last dive of the day. Koh Tachai Pinnacle is Kath’s favourite dive site and for good reason. It is a dive site that can throw the unexpected. With no current it was kind to the divers as it was minimal however, the action was amazing with the predators hunting in a frenzy and the resident huge school of barracuda was spiralling close to the pinnacle in a hypnotic way.

Day 2 and it was decided that if there was a chance to see a whale shark we would do our first dive on Koh Tachai Pinnacle. We were the only divers initially on the pinnacle and it was the most amazing experience ever….1 whale shark great!!!! 2 whale sharks!!!! 3 whales sharks!!!! 4 whale sharks on the same dive….How fantastic is that?? We were blown away. When the divers surfaced a group decision was made to spend the rest of the day on Koh Tachai and every dive delivered multiple whale sharks, trevallies, and huge school of barracudas. This was Koh Tachai at its’ best.  During the surface intervals we were snorkelling with them as Captain Pu managed to secure the prime mooring. What a fantastic experience for the non divers and the crew on the boat. Kath was one of the first in the water after breakfast with the snorkelers.

The next morning the engines started at 5am and then we motored to Richelieu Rock for 2 dives. This is a gorgeous pinnacle in open sea. The diving was excellent with wonderful visibility. Richelieu is great for all marine life from predators to macro. We saw a host of things including barracudas, banded pipe fish, seahorses, cleaner pipe fish, a brown and white bent stick pipe fish, mantis shrimps, many different shrimps, the list is endless. Then back to Koh Tachai for whale sharks and yes we got them as soon as we jumped in 3 in total!!!! They are the most beautiful creatures. To see them glide through the water effortlessly is a delight for any diver. Kath and Matthew Cooper had the most incredible end to a dive when they were on the top of the pinnacle. Kath turned around to see the biggest manta she had ever seen coming straight for them. Screaming through the regulator Matthew turned to see this magnificent beast coming directly at them. A great way to end a magical dive!!!  When we left the site as there were many boats and we decided to leave on a high and head for Koh Bon. This was a great decision as we had heard on the radio that there were manta rays. Maybe they would still be there. Captain Pu told us he was going to drop us on the reef and all we can say is thank you Pu. We were in the water for a very short time when we saw a glimpse of a manta in the distance. A few moments later we were interacting with 2 mantas spiralling amongst us. These majestic creatures were putting on a show and they did it so well. What a fantastic end to a wonderful day….couldn’t beat that.

Day 4  and back to the Similans. Our first dive on West of Eden was a gentle dive with very little current and great visibility. This has some wonderful coral blocks and massive granite boulders which is home for a host of beautiful smaller reef fish and tiny critters such as nudibranch. A good start to the day. Then to our final dive on Shark Fin Reef, a gentle drift along the fantastic granite rock formations. Shark Fin is a stunning dive site for the topography. The amount of fusiliers on this dive site is incredible, they are like a train that never stops… The powder blue surgeon fish are amusing as they try and play with the bubbles exhaled from the divers. A lovely dive for the end of a wonderful trip.

It has to be said that this trip was exhilarating, exciting and it certainly had the WOW factor. How many whale sharks do we normally see? This was one that gave us 4 on one dive site. We did 6 dives on Koh Tachai Pinnacle and 5 of them delivered the most amazing experience that we will never forget….multiple whale sharks!!!!

The Mai Khao Marine Turtle Foundation based in the north of Phuket had it’s 4th annual release of 100 turtles on the 29th of March this year. Scuba Cat decided to support this by sponsoring a release of a turtle back into the Andaman Sea. The important annual event is organized to raise funds for and awareness of the plight of Phuket’s critically endangered sea turtles and is supported by the Phuket Marine Biological Center and the Royal Thai Navy, the event sees the release of rehabilitated green turtles back into the Andaman Sea.

Sarah Kench, the GM and Course Director, Kath Ridley the tour leader of Scuba Adventure and Debbie Woods The Customer Service manager all went along to support the event held on the beach at Mai Khao, along with Jade, Debbie’s 1 year old daughter.

There were activities such as batik painting and turtle awareness going on throughout the afternoon along with light refreshments and a monks blessing for the new to be released green turtles.

After waiting to queuing in a busy registration Scuba Cat were allocated number 73 for release, this was a 10 month old green turtle, Sarah was the one elected to release it.

After some training we were called to beach in groups of 5, this allowed the turtles enough space to comfortably be released without big crowds around them which could cause stress. They were taken from holding tanks to the water edge and set free, the waves then helped them out to sea.

Phuket’s sea turtles face multiple threats and their numbers have severely depleted in recent years. Commercial fishing kills thousands of them every year. Many more die from eating or becoming trapped in plastic debris littering the ocean, not to mention entanglement in fishing nets and being hit by speedboats.

Every 2,500 baht raised pays for the rehabilitation of one turtle and its release back into the Andaman Sea. The work done by the Mai Khao Marine Turtle Foundation (founded by JW Marriott Phuket Resort & Spa), the Injured Turtle Rehabilitation Program (under the Phuket Marine Biological Center) and the Turtle Hatchery Program (under the Royal Thai Navy) is possible thanks to ongoing financial support from the Phuket community.

Phuket’s sea turtles are facing multiple threats and their numbers have severely depleted in recent years. Commercial fishing kills thousands of them every year. Many more die from eating or becoming trapped in plastic debris littering the ocean.

Mai Khao beach and the northern end of the adjacent Nai Yang beach are the only beaches where turtles lay their eggs in Phuket . These two locations have a long natural deserted beach stretching more than 17km. They form part of the Sirinath National Park, which is a protected marine and coastal area.

This is a nesting area of the giant Leatherback Turtle, one of the world’s most ancient species. These turtles on average weigh 450 kg. However, the Leatherback population is fast diminishing and its status is very critical. It is the only turtle without a true protective shell, though its outer protection is leathery scale-less skin – hence its name.

The breeding season of the turtles is November to March. The females come ashore just after dusk and return to the ocean as dawn breaks. The nesting site is selected and they dig a small pit using the rear flippers where they lay between 40 and 180 eggs, they try to conceal the nest once they finished by covering it with sand. The whole process takes about 1 hour. If left to nature the hatchlings will emerge after about 60 days digging their way out of the pit , usually at night so it is cooler and run towards the sea. House lights and hotel developments along the beach can disoriented the young turtles causing them to actually crawl the wrong way going away from the sea. Some large Phuket resorts have focused their attention on ensuring that turtles stand a chance of survival in the Phuket region by making the beach area environmentally friendly to the nesting turtles.

At nesting time environment groups and the local villagers of Mai Khao work very hard to protect the eggs. They take the eggs to their hatchery, where the baby turtles are protected from the vagaries of nature as well as human exploitation. During the breeding season, the local villagers patrol the beaches at night and keep records of the eggs that have been laid.

The Mai Khao Marine Turtle Foundation was launched in 2002 and raises funds and awareness for the plight of the critically endangered giant leatherback turtles that nest in the area. It also co-ordinates with the Phuket Marine Biological Centre (PMBC).

Like most scuba divers, you were probably already fascinated with the beauty of both the scenery and marine life of the underwater world from the first dive. The next step is capturing this unique environment by taking some images with underwater photography. Whether you intend to take snapshots to show your friends and family, or create beautiful images of the world below by traveling to exotic destinations, you have to start somewhere.

At some point or another, most divers have thought about learning how to shoot underwater photography, many have taken the adventure dive as part of the advanced open water course. The affordability of digital cameras and the ability to instantly see the outcome of your efforts has reduced the barrier to trying and the learning curve to almost nothing. Add the ability to shoot video clips with even the most basic point & shoot cameras, and you can make scuba diving vacation memories to be the envy of your office and family.

There are many things to think about BEFORE picking up a camera.
Good buoyancy control is an essential skill not only for diving but for taking good photographs too. This needs to be mastered before adding the extra equipment and objective of taking a camera underwater. Taking the Peak Performance Buoyancy certification can do this.
Knowing the marine life you are going to photograph is a pretty big part of photography too, you need to be able to predict the movements and behaviour to get the best images. This can be studied in the underwater AWARE Fish ID and Naturalist specialties.
Obviously you will have new equipment with you, (the Camera) so a course, which teaches the use of this, is a good start point too, the Digital Underwater Photography course will cover this for you.

You may be a competent or experienced photographer on land but moving this experience underwater has a whole different set of issues to think about.

The first step to understanding any kind of photography is understanding your camera. If you have a new camera and housing, take the time to read the manuals. It may seem like a simple thing to do, but many people don’t.
As with any new diving equipment that you purchase, you should try out the photography equipment in a pool prior to diving, whenever possible. You will also want to take new camera housings underwater without the camera to ensure they are functioning properly. You don’t want to find problems with the housing while your camera is in it, this could lead to an expensive lesson.
No matter what camera you have, from an entry-level digital “point & shoot” to the most expensive dSLR , there are ten rules of underwater photography that should always be remember. Many of these rules are related to composition in the underwater environment and every photographer can benefit from proper composition.

1) Get Close, and when you think you are close enough, get closer again

Underwater photography differs from conventional wildlife photography, as it needs to be conducted up close. To get the best results you have to put as little water between your lens and the subject as possible.

The water holds small particles in it that reduce the contrast and sharpness of your image by dispersing light, this is called backscatter.

Water absorbs the light very quickly, and the most common complaint for new underwater photographers is the dull colours of their images.by getting closer and therefore removing the amount of water between the camera and the subject will mean a clearer, sharper, and more colorful image.

2) Shoot Up

Pointing the camera down as you take an image is often easier but will not result in the most interesting images.

Often the subject is lost in the background of reef as it is a more cluttered area. Pointing the camera more up can lead to clearer backgrounds and much more interesting images as you have contrast between the foreground and background.

3) Focus On The Eyes

A focused image is obviously important, but where you focus is too. Try to keep the eye of the subject in sharp focus, use this as the centre of the camera’s focal point.

4) Keeping Yourself Focused
Diving with a camera and diving without a camera are two totally different activities. After diving with a camera, you may find that those dives very different.
Patience is an extremely good quality to have when doing underwater photography, you may need to wait for divers to move out of the frame area, or for the subject to become used to you and start to behave in a more normal manor.

As a casual underwater photographer you dont need to be obsessive, but a level of personal focus and attention to detail will take your photography a long way.
Try to focus on a particular type of underwater photography, such as close-up or scenic and perfect your skills before moving on to the next type of shot. Avoid the shotgun approach of trying to capture everything that you see.

5) Use a Strobe

All divers know that water absorbs light, and therefore reduces the colour of the images you take, a strobe can be a way of restoring this.

Adding artificial light can give instant results to the photograph, but it is important to get the exposure right. Now most units come TTL ready and should give the correct light in all, but the most difficult conditions.

The photographer though has to ensure it is pointed in the right direction. Sounds simple, but if it is incorrectly positioned not only does it alter the quality of the image, but it also refracts the light so your subject appears closer and larger than it really is.

6) Shoot, Review, Adjust, Rinse, Repeat

Be patient, even though the digital photography gives us instant access to images, they still take time to perfect. The learning curve is shorterned by being able to see the image you have taken instantly on the screen. Take advantage of this by reviewing these images immediately after the photo has been taken, correct and re-take the image, adjust for composure, light, colour etc.

7) Go Manual
Starting off in auto mode is not a problem. But auto settings can only get you so far in underwater photography. To really control the exposure, colour and sharpness of your images you’ll need some degree of manual controls.

8) Maintain Your Equipment

Water and electronics don’t mix well so it is important to take your time when setting up your camera and housing. Make sure o-rings are clean and greased, but not over greased. A strand of hair or spec of dirt can be the difference between flooding your camera or using it. Always rinse your camera gear off with fresh water after every dive,never let salt water dry on your equipment.

While out on the dive boat be sure to keep camera gear out of the sun and away from heavy dive gear like scuba tanks and weight belts.

9) Respect the Environment

Remember, we are privileged guests in the underwater world, respecting the environment and marine life should be one of your top priorities. Before you start taking your camera underwater it is important to have excellent bouyancy skills, this will help protect both yourself and the environment around you. Keep all of your gear streamlined as to minimize the potential of a gauge or hose getting entangled or damaging the reef. Never harass or touch marine life. virtually everything you could touch is alive, touch it and it will damage it or even worse.
It can too often be seen the photographers who want a shot no matter what they have to break, kill or damage. It is important to stress to anyone who is keen to start underwater photography that as well as learning how to take a picture, you must also be environmentally aware.

If you have to damage anything to take a shot – don’t take it. Sometimes it is better to look and enjoy than try to take a photograph.

10) Have Fun

Don’t forget that underwater photography is supposed to be fun. Don’t get too caught up in the technical side. Start off with the basics, get a feel for it, and learn the technical side later.
Most of all, remember what you learned in your scuba diving class. You are a diver first and then a photographer. Your safety and that of divers around you depends on keeping this in mind at all times.

When diving over sand area’s of a dive site there are so many interesting critters that are often not seen or ignored by divers, one of these is the symbiotic pairing of the goby and shrimp.

Almost all of our dive sites by there nature have sandy bottoms and instead of passing quickly over them it is good to swim slowly and enjoy watching the behavior of these interesting room mates.
The sandy bottom of the reef is full of interesting creatures and fascinating methods have been devised for survival techniques used by reef inhabitants to prevent becoming food to predatory fish. Often this results in some interesting partnerships between marine creatures. One of the more curious relationships that most divers could have come across is that between the goby fish and the shrimp.
The little goby that firmly stands his ground outside his burrow belongs to a very special group of gobies called “shrimp gobies”. There are 70 or so brightly coloured shrimp gobies recorded worldwide in tropical waters and the western Indo Pacific is home to most of them. Their uniqueness is that they live in partnership with “pistol shrimps”. Pistol shrimps are so named for the loud snapping sound and the jet of water that comes from the rapid closing of a modified claw.

The gobies spend their day near entrance ways keeping their eyes peeled for predators, such as jacks and lizardfish, while the hard-working shrimp bulldoze sand into the open from the burrow below.
The front entrance of the burrow is often reinforced with bits of shell and coral put in place by the shrimp.

The goby will usually sit at the entrance of the burrow maintaining a constant vigil against potential predators, while the shrimp is clearing gravel from the burrow. Whenever the shrimp needs to dump gravel outside the burrow, it is usually exposed to potential predators. However with the Goby keeping lookout, the shrimp places one tentacle on the Goby while exposed, so if the Goby darts inside the burrow, the shrimp is instantly alerted of the presence of a predator and it too darts back inside the safety of its burrow. Often pairs of gobies or pistol shrimps will inhabit the same burrow.

They work between sunrise and sunset, resting with the gobies, inside the burrow at night. And like most homes, burrow construction varies according to its inhabitants. Scientists have even found that the sizes and shapes of burrows depend on the type of sediment available and to some degree on the species of shrimp. So the goby gets a professionally constructed and safe house away from predators, and somewhere to lay its eggs.
Gobies eat micro-fauna and sometimes tiny fish they find near the bottom, the shrimps feed on what they find in their burrowing and hence they do not compete for food.

The special relationship that exists between these two species is called symbiosis. Symbiosis literally means “living together” and can take more than one form but it is always between individuals of different species. It can mean, for example, that only one of the species benefits with no effect on the other, or that one species of the pair benefits but the other is harmed in the process. In the shrimp-goby case both species gain equal benefit and they significantly increase their chances of survival in a hostile world. This particular type of symbiosis is called “mutualism”. Their relationship is one that has developed through a mutual need and benefit to both species.

These animals are dependent on each other. Remove the fish, and the shrimp stops burrowing; the shrimp forage while burrowing, so without a fish, they grow more slowly. The shrimp need their guard goby, and the guard goby needs its shrimp: deny the goby shelter in a burrow, and it will promptly be killed by predators (someone did the experiment). The shrimp keep the goby clean, too: they groom it.

So how do the Gobies and Shrimp find each other in the first place? Shrimp-goby researchers have been trying to figure out this one for a long time, and have conducted numerous experiments to determine whether the Gobies find the shrimp, or vice versa, and also to determine whether they locate each other optically or are attracted chemically. There has been no definitive answer as to who spots who in this symbiotic relationship but it appears that the short sighted shrimp uses chemical senses, and the goby uses it’s much better developed visual sense for finding each other at a very young stage of their life.
