Over the past few years more and more Atlantic bluefin tuna have been sighted off the coasts of the British Isles. This includes off Shearwater II, and we have seen magnificent displays of feeding bluefin tuna during the late summer and autumn since 2015. As well as working at Marine Discovery I’m a postgraduate student at the University of Exeter …

The paper has finally been published in the journal of Aquatic Mammals: http://www.aquaticmammalsjournal.org/index.php… De Boer, MN, Jones, D., Jones, H. (2017). Ocean Wanderers – …

Upon arrival it soon became clear that the whale in question was very close to the strandline but still fully submerged so it was evident that …

At least 17 of the inshore pod of bottlenose dolphins hung around Penzance all day today. They displayed many behaviors from feeding to socialising to resting, which were interesting to watch. We have been keeping photo identification records of the South Wests inshore bottlenose dolphins since 2007 and now have nearly 40 recognised individuals in our catalogue – the 2013 version …

This one was swimming along barely breaking the surface, which made it hard to spot. The calm conditions still allowed us some good views. It makes you understand how vulnerable they are to being hit by fast moving boats when you see them like this. One of the reasons we switched to the sailing catamaran was to slow things down …

Today we were watching a pod of common dolphins feeding while gannets dived all around. It was quite a spectacle and was made even better when the dolphins came over to do some human watching. It can be hard to tell who’s watching who sometimes. Here is a compilation of clips from today’s dolphin watching trip.

Today we were surprised to see the first basking shark of the year. I’m not sure why we were surprised as our first basking shark sighting normally comes in early April.

The diatoms and coccolithophore populations rapidly grow as they feed on the nutrients stirred up …
