Scientific research on Risso Dolphins - Azores

For many years Dutch Marine biologist Karin Hartman has been researching the population of Risso Dolphins in the seas around the island of Pico of the Azorean archipel. Climate change seems to effect the behavior of this rare species of dolphin. To understand these effects better, there is a need for satelite tags to be able to track the animals. More knowledge will lead to proposals for better protection.

Extend the scientific knowledge on Risso Dolphins

The Azores are a hotspot for 25 cetacean species and form a critical habitat for resident Risso’s dolphins. A study, exploring 17 years of sighting data, suggests that global warming is adding pressure by increasing food competition with transient pilot whales. To better understand the interactions between these two species, analysis of their movement patterns, using satellite tags, is needed. This will provide ecological insights that will help adjust conservation measures, including the IUCN species status. 

Where is the donation of GBTN spend on?

The money will be spend on the tagging project for the two type of species that will be researched: the Pilot Whales and the Risso dolphins.  It is used for co-funding the purchase of 5 tags, and the associated transmissions costs for 6 months (total costs € 20.000). In june 2024 a tagging expert from Madeira will be available to assist with the transponders.

Nova Atlantis Foundation is a Dutch research institute, based on Pico island (Azores, Portugal).

“Our goal is the conservation of the coastal and pelagic waters of the Azores. Recognition of these waters as Marine Protected Areas would be a major step towards that goal. We contribute by providing data on marine mammal ecology to stakeholders, such as local authorities, the scientific community, environmental NGOs, and through lobbying. Key species in our behavioural, ecological studies are the resident Risso’s dolphins.”
