Update from our marine conservation volunteering holiday in the Azores archipelago, working on whales, dolphins and turtles
Having welcomed group 2 to the expedition, we quickly embarked on the project orientations, equipment briefings and scientific survey training. Fortunately, this all went to plan, so we could make the best of the available weather window, to get out on our survey vessel – Physeter.
This meant a longer than anticipated trip on Sunday, which resulted in some well-earned records. One of our team has been on the Azores expedition on two previous occasions, but had yet to see a ‘true whale’, despite being party to an orca sighting in 2019 (the largest member of the dolphin family). This record was soon broken with a fin whale sighting and followed up with more blue whale records. If at first you don’t succeed……..it is worth trying again and again. Congratulations Neil, a great way to ‘chalk up’ your first whales!
Our second day at sea also started with the now obligatory blue whale sighting. Yes, these magnificent beasts have now been spotted every day we have been at sea in 2025 – that may also be a record for the expedition. This was followed by a rather frustrating group of sperm whales, who seemed more interested in socialising with each other and not feeding. This means no diving and that means no fluke pictures with which we can identify individuals. Some common dolphins provided some intermittent entertainment, whilst we waited, and waited and waited. Of some 25-30 whales in an area south of Pico, we returned to port (after a wet and bumpy journey) with fluke pictures from only two. Kudos to Pedro (our skipper) for getting us back to port.
The Atlantic weather systems decided the next day would be on land. This not only gave us a chance to process some of the data from the previous days at sea, but also learn how the data can be used by others. Maria Ines (a Masters student from the University of the Azores) gave an excellent presentation of spatio-temporal dynamics of common dolphins and Atlantic spotted dolphins in the Azores, based largely on POPA (Programa de Observação para as Pescas do Açores = Observation Programme for the Fisheries of the Azores) data, which is also a key element of the expedition data collection. Understanding the importance of the Azores archipelago for these species is contingent on the availability of long-term data sets.
We look forward to more sightings and more data in the coming days.
