There from day 1, Rich is our Director and co-founder of the MWSRP (and also one of the reasons why we have such a long name). His unwavering determination and commitment to the research and protection of whale sharks is why we are here today. 1. How did you get a job with the MWSRP? […]
With a passion for all things marine and boundless energy, Clara is one of our inspirational in-field coordinators! 1. How did you get a job with the MWSRP? I first came as a volunteer in November 2016. I spent two weeks on the volunteer programme and when I got back to Spain I knew […]
Things You Didn’t Know You Didn’t Know About Whale Sharks As we come towards the end of an incredibly exciting year we thought it would be nice to share some our staffs’ favourite facts about whale sharks and why we love these massive fish so much! Every individual whale shark has a unique pattern of […]
Flash Competition! Who has the earliest film / photographic record of a whale shark in the Maldives? We were recently sent some footage from the 90’s of a whale shark seen in the Maldives and that got us thinking: our database extends back to 2006 when we went on our first expedition, but just how […]
Why on earth is a whale shark research organisation writing about jellyfish?! Well it’s World Jellyfish Day and it’s a little known fact that some of the team have rather a soft spot for jellies! Why? Well check out these 10 fun facts and hopefully you’ll come around too…! They’re delicious! The crown jellyfish, […]
As the human population continues to release more and more carbon dioxide into the atmosphere we have to ask ourselves, where does it all go? Unfortunately most of the CO2 released by fossil fuels is, and will continue to be, absorbed by the ocean. Over time this causes change in the oceans pH levels (known […]
Written by Edward Doherty, our In-field Marine Biologist, for the Blue Planet Society. It may surprise you that 100 million sharks are killed by people each year. What might surprise you further is that this is a conservative estimate and the number may in fact be as high as 273 million. That’s a whopping 31,164 […]
Hi, I’m Sam, an MSc student from the university of York who was lucky enough a couple of months ago to come to Dhigurah Maldives to work for and collect data for my Master’s dissertation, on the factors that influence Whale Shark’s preferred aggregation sites. Now, after having returned to the UK and completed my […]
It is with great excitement that MWSRP introduces the latest research tool to our toolkit – ‘Valla’ is a Yuneec Typhoon H hexacopter. Valla is the dhivehi word for the beautiful terns that nest in South Ari MPA.
Made possible through your generous support for the t-shirt fund raiser held by MWSRP in August, the hexacopter will soon be flying high above the waves of the South Ari atoll MPA. It promises to add a superb extra dimension to MWSRP’s whale shark survey work.
The MWSRP has earmarked three pilot projects for the first 6 months of usage. They are;
- To carry out exactly repeatable survey transects of the reef for whale shark counts. The hexacopter is fully programmable to fly between GPS waypoints, allowing it to consistently follow an exactly defined survey path. From a scientific perspective this is very important in controlling experimental variables. It allows testing of whale shark numbers against other changeable environmental variables of research interest, such as lunar stage, tidal state and sea surface temperatures, as well as opportunistic comparisons of control surveys versus periods of coral spawning etc. The MWSRP does this to some extent by vessel already, but the current method has frailties in terms of consistency. Not to mention, the team get in the water whenever they see a whale shark, while the hexacopter will just record and move on! The footage obtained will not be ‘real time’, so the hexacopter will not be able to be used for finding and counting whale sharks directly. The high definition 4K camera on board will record the 25 minute survey, with the team reviewing footage and counting whale sharks at a later date.
- To assess the feasibility of measuring whale sharks from the air using exact elevation to triangulate the total length (TL) of the shark. A research idea borrowed from cetacean researchers, this method offers another method for establishing whale shark size to complement the in water methods of laser photogrammetry, tape measure and estimation. Accurate and precise measurements of a whale sharks’ overall length are key to growth rate and population demographic studies, as sexual maturity is linked to size in whale sharks. By adding another measurement method to compare against the current systems, the team hope to refine the precision of all methods and so boost the quality of the research outputs.
- To gather undisturbed whale shark behavioural imagery data. No matter how closely you follow the whale shark encounter best practice guidelines to reduce the impact your presence in the water has on the whale shark, the fact that you are there and that the vessel you are using is in the proximity means you cannot, from a scientific perspective, completely remove your presence as a potential cause of any behavioural activities being observed. Whale sharks are evolutionarily highly evolved to detect and react to stimuli in their underwater environment. Humans splashing around with fins and masks and boat engines are definitely something that would be noticed! But a hexacopter hovering well above the shark, in the air and away from its carefully crafted senses will likely to go completely undetected by the shark. This means that true behaviour can be observed and compared to environmental and other variables, as well as compared to the behaviour of the shark when the team is in the water to see actual responses to human presence. It really is a game changer in terms of no-impact scientific observations for whale sharks.
We’re hoping one by-product of this research is to capture breath-taking imagery of the sharks undisturbed in their wonderful natural environment to be shared with and appreciated by all who have an interest in this species, and to bring the majesty of this species into the eyes of those who are yet to come under its spell!
The MWSRP will be operating the hexacopter to guidelines which minimise or remove any disturbance or privacy concerns other water users or nearby resorts may have. The top concern is to capture innovative research data in a way that does not disturb others.
The MWSRP welcome any communications from people interested in the hexacopter, its capabilities, the research it will conduct and the research outputs it creates. Please email info@maldiveswhalesharkresearch with any questions, comments or concerns you may have about this exciting new tool.
Hi, I’m Shamyl. I’m a huge fan of the sea and wanted to explore my passion for it by joining MWSRP. During the month of November, I came out as a volunteer with MWSRP learn more about the ocean. I had recently finished working on a tuna fishing boat where I learned a lot about […]
