A Happy New Year To All!!

We wish all our visitors a safe, happy and prosperous 2009!

We will not be able to add new posts to the blog over the next few weeks while the team is out on the research expedition to Djibouti, but we will update you as soon as we are able!


In the mean time have a great New Year!

Djibouti expedition draws near

As most people get into the pre-Christmas rush of last minute card writing and present buying scattered around the world a dozen or so people are getting excited about another activity to take place shortly afterwards, the whale shark expedition to Djibouti starting on New Years Day!

Both of the two weeks of the expedition are now fully booked with the team from MCSS and Megaptera being joined by cameraman Dan Beecham and photographer Thomas Peschak from the Save our Seas Foundation as well as a total of some six eco-volunteers. Life aboard the Deli is going to be pretty hectic from the sound of things…

The expedition is going to be targeting the Arta area in the Gulf of Tadjoura which is the gulf on which Djibouti city is located just past the southern end of the Red Sea. This gulf is an inlet of the Indian Ocean caused by the fault line of the northern end of the great East African Rift Valley that transects Djibouti, Ethiopia and Kenya.

The area is geologically and volcanically active as evidenced in 1978 by the eruption of the Ardoukoba volcano. The seabed shelves steeply from the coast of the Gulf dropping to 100 m depth around two km offshore and to around 450 m depth in the centre of the Gulf of Tadjoura. The volcanic lanscape is dramatic if somewhat stark and the volcanic activity has narrowed the gulf down to form the ‘Devils Goblet’ and then pinched it off entirely leaving Lac Assal completely land locked and evaporating away. The surface of this lake is now 450 m below sea-level and the evaporating seawater has left vast salt pans with dramatic areas of salt crystal structures; this is a must for all visitors to the area and a half day trip has been planned.

The whale sharks in Djibouti are interesting in that they spend a lot of time vertical feeding and at night are drawn in to feed on swarms of tropical krill that are attracted by the boats lights...

Five whale sharks feeding on tropical krill at night... not quite sure how we would get the photo IDs done on this lot!

Off special interest to the whale shark team is the fact that very deep water is close to shore. This feature coupled with the fact that on the previous expedition in 2006 the aggregation of sharks was found to be composed of very small sharks, with several of just over 2 metres, may indicate that this area may be a nursery ground for whale sharks. The rationale for this is that globally the number of neonatal (less than 1 metre) whale sharks seen is tiny, less than 15 records, this despite the high level of fishing in coastal areas. This has prompted the idea that when first born the 65cm pups stay
in very deep water to keep away from other predators and only come into shallow waters when they are around 4 m in size. Djibouti with its aggregation of very small sharks may thus be an area close to where the youngsters are.

While our team aren’t able to get to those sorts of depths, an ROV can and the BBC Natural History film unit just happen to be in Djibouti at the same time and happen to have an ROV! Their main aim is to explore the beginning of the East African Rift but having heard of our expedition and the potential of this being a nursery area they are going to see if they can find any baby whale sharks at the same time!


So this really is going to be quite an adventure... we will post news to the blog but as there is no internet connection it will probably be once we get back to civilisation...

2009 Seychelles Programme Internships

The Seychelles monitoring programme is recognised as one of the largest whale shark monitoring programmes in the world (see comments on BBC Natural World); the programme integrates eco-tourism with research activities and in so doing captures an enormous amount of data both about the sharks, their behaviour and the environmental characteristics of the habitat. In view of the large amount of data that is now being captured a structured approach is necessary with respect to volunteer participation. Also, as it is very time consuming to train new applicants part way through the season, the programme will be run with 6 internships being offered on a full-season basis.

The 2009 internship programme will last for 10 weeks from 24th August to 31st October. The first week will be an orientation and training week, week two will hopefully be getting some practice whale shark trips and helping the pilots set up the micro-light aircraft, and as of week three (Sept 7th) the monitoring activities proper will be implemented.

The six interns will work as two teams, one for each monitoring boat, and each team will be supervised by a team leader who in turn will work under the project leader. The two team leaders have worked with the MCSS programme for two years and both have considerable monitoring and volunteer organisational experience. The interns will be accommodated at the MCSS premises on the coast at Glacis, NW Mahe on a self-catering basis. The property has two bedrooms set out dormitory-style for a maximum of four persons each and each bedroom has an en-suite bathroom facility enabling male - female separation. There is a large living-room and kitchen for communal use with washing machine and all usual amenities. There is also a large veranda connecting the living accommodation to the MCSS office. Wireless internet service is available throughout the premises.

The interns’ training and duties will cover the full range of activities associated with the MCSS whale shark monitoring programme including:

- The Seychelles whale shark programme:- findings, achievements, why it exists
- Study area orientation and geography
- Basic whale shark information and biology
- Whale shark data collection:- filling out forms, writing up data, the systems and spreadsheets
- Photo identification:- sorting and filing images, pre-process preparation, matching software
- Laser-metrics: measuring sharks using underwater laser with digital photography
- Snorkel training and water skills development for whale shark activities
- Communications training:- between micro-light and boat and between boats
- Boat operations:- logistics, protocols and safety
- Micro-light aerial survey support and data handling, software use
- Environmental monitoring equipment use, data capture and handling

The costs of the internship programme, inclusive of shared accommodation and training is Euro 2350 per person for the ten weeks. These costs do include utilities (power and water) but exclude food costs, private local travel and international travel to and from Seychelles, all of which are the intern’s responsibility.

Seychelles whale sharks on BBC TV

On Tuesday 18th November BBC2 aired the first screening of the whale shark episode in their series the Natural World, as many of you have contacted us to let us know!

This episode documents the work of Dr. Mark Meekan in trying to unravel the mysteries of the whale shark and includes several sequences filmed here in Seychelles with the MCSS whale shark programme in 2007. While the sequences may be brief a number of our key people are on the film and it does portray the Seychelles programme well describing it as the “largest whale shark research programme in the world" with "massive tourist integration". So all of the interns who worked with us in 2007 can be pretty happy with their contribution to the filming of this episode.

The episode was made by the Big Wave production company and includes much underwater footage captured in Seychelles by Rory McGuinness, who proved to be both an exceptional cameraman and an accomplished diver, keeping up with the sharks while pushing a massive video camera in front of him. There’s also a sequence of a whale shark having a poo which seems to have captivated the press!

The episode certainly ranks as one of the most important pieces to raise public awareness about whale sharks for many years and will doubtless be syndicated onto the various TV channels in due course. For those of you who didn’t see it the episode is to be repeated on Sunday 23rd at 8.00pm and is also available for download through the BBC Natural World iPlayer (only available in the UK).

Another late season surprise!

We recently received a series of whale shark photos taken by Frank Steinberg back in April of this year when on a diving expedition to Aldabra and the Southern Islands of Seychelles.

While it is always nice to receive photos of whale sharks from visitors, the fact that they were taken off Astove island some 800 miles south of Mahe makes them all the more interesting. Also, the outer islands of Seychelles seldom record whale sharks even though our tracking studies do indicate that whale sharks from Mahe do make the journey South West towards Mozambique.

Frank Steinberg's photos of the whale shark swimming over the edge of the Astove wall with two large mottled remoras clinging to its back

Frank’s shark was around 4-5 metres in length with a bite out of the trailing edge of the left pectoral fin. It was accompanied by two very large remoras that were firmly fixed to its back… like the sighting of the shark these were unusual as they were the large mottled brown Remora remora species rather than the slender striped Echeneis naucrates which are the common remoras found on whale sharks around Mahe.

Frank was also able to get underneath the shark as it swam along the top of the famous Astove wall and got a few shots from below which confirm that the shark was a female, also unusual as most sharks found around Mahe are males (see the side bar for this seasons statistics).


The photo series yielded both left and right identity shots which Katie Brooks eagerly fingerprinted through the I3S photo ID programme and then ran against the Mahe whale shark database…. and it’s another new shark! We are now waiting for the arrival of Simon Pierce’s database from
Mozambique to see if this has been seen in his area at all.

We wonder if there are going to be any further end of season surprises?

Last minute shark…

Well although the monitoring season has finished the local population of whale sharks don’t seem to have heard the story and there are definitely still a few hanging around to the delight of visiting divers.

One such lucky group were the divers from Dive-Crew, a UK based dive-tour organisation who had been persuaded to visit Seychelles by their leader Colin Miles in the knowledge that they might just get a chance to see a whale shark. The 25 divers knew that they were outside the peak period but as diving was their main objective they were happy with the potential for an opportunistic sighting.

And on the 12th of November during a dive on Grouper Point with Dive Seychelles they were lucky indeed as a 5 metre whale shark came in to visit them! Steve Sparkes was the one with a camera at the ready and managed to capture some good images that everyone in the group wish they had!

After a somewhat belated presentation on the MCSS whale shark programme by Dr. David, Steve was happy to pass on the images for identification. Katie Brooks was more than eager to run them through the I3S system, partly to escape from double checking data from this season, but also to see if this was a known shark or a new one…. And to everyone’s surprise it turned out to be a new shark and became the 38th new shark identified in 2008.

The key identification area that confirms this as a new shark sey.2008.038 !

And so although the season is formally over there are still a few sharks around to distract the team members from the end of season ‘housekeeping’ chores!

Jean-Michel Cousteau visits the MCSS team!

On the very last day of operations for the 2008 whale shark season, the MCSS monitoring team members had a surprise visit from renown marine conservationist Jean-Michel Cousteau.

Jean-Michel was visiting Seychelles aboard the Regent and had arranged to dive with the Underwater Centre / Dive Seychelles; David and Glynis had known about this well in advance and had arranged with our micro-light pilot Johan that he would stay on an extra week to see if there were any whale sharks around for Jean-Michel’s visit….

In the morning things looked hopeful as the one and only whale shark found on the aerial survey was in the North-West sector; however, by the afternoon the shark had disappeared. This didn’t deter Jean-Michel from paying the team a visit in the Conception Channel, after his dive on Shark Bank, and pilot Johan did a low-level ‘fly-by’ to welcome him.

Jean-Michel Cousteau meets the MCSS whale shark team leaders, from left Luke Riley, David Rowat, Jean-Michel and Katie Brooks.

After the boat ride back to the dive centre Jean-Michel was introduced to the Dr. David and to team leaders Katie Brooks and Luke Riley, where he was interested to learn about the programme and the broad reach of both intern participation and the work we do. There is another Seychelles visit planned in 2009 and so we may get another chance to find a whale shark for Jean-Michel then!
