Today finds us at the Egmont Islands, off the south west corner of the Great Chagos Bank. We've come here looking for manta rays, which we know from previous visits to be a common sight around the reefs and within the lagoon. The purpose of our visit here is to acoustically tag some of the manta population and deploy some of our acoustic receivers to track their movements over the coming year. The aim is to understand how resident the mantas of Egmont are, and the influence of the tides and other natural cycles on their daily movements around this small atoll.
Firstly, however, you need to find a manta, and this year we have a new tool at our disposal – a Phantom camera drone. Able to relay live images from a bird eye view to the pilot on the deck of the boat, we can locate groups of mantas and direct the tagging team to the area.

Aside from the science workload, our most senior scientist and the trip’s doctor have been moonlighting in the galley, producing excellent desserts to complement the already abundant meals aboard. Hopefully all the hard work on deck will keep waistlines in check!
