In this website you will find information about the Icelandic Orca project
We aim to learn more about the role of orcas in the Icelandic marine ecosystem
Our research focuses on the social and foraging behaviour of orcas while monitoring which individuals can be regularly seen in Iceland to gain a better understanding of the population size and status.
To achieve this we use a variety of techniques and we work during times of the year when the whales can be reliably seen near the coast. In the summer we work in the archipelago of Vestmannaeyjar, in Southwest Iceland, while in the winters of 2013-2015 we have worked in Grundarfjörður, in the Snæfellsnes peninsula. In this section you can find out more about our project and the research techniques we use.
The Icelandic orcas
Studies of orcas in Iceland began in the 1980’s, when the Marine Research Institute (Reykjavík) started documenting the individuals observed in the herring overwintering grounds of East Iceland. However, there hasn’t been dedicated long-term monitoring, as done in other populations, such as the better known North Pacific residents or transients. For this reason, we still know little about this population. For example, we don’t know whether all whales are fish-eaters or whether they organize into stable family groups. Nevertheless, research so far seems to indicate that in some aspects this is a unique population. In this section you can find out what has been discovered about Icelandic orcas.
