ORCA OceanWatch

ORCA OceanWatch is an exciting initiative involving seafarers in the collection of data on whales, dolphins & porpoises that they encounter whilst out to sea as well as educating bridge crews about the risk of ship strike (whales being hit by ships).

Critical cetacean habitat

The event aims to raise the profile of British and European cetaceans while collecting a large amount of data over a concentrated period of time. The data will also contribute to the National Whale and Dolphin Watch in collaboration with Sea Watch Foundation. 

ORCA OceanWatch 2018 took place between the 28th July and the 5th August 2018. During this time, seafarers recorded their sightings, whilst ORCA Marine Mammal Surveyors and Wildlife Officers were out in force to survey as much of our seas as possible. In 2019 ORCA OceanWatch will be taking place between the 27th July and the 4th August. If you would like to get involved in please contact Anna Bunney on This email address is being protected from spambots.

Key facts of the 2018 ORCA OceanWatch include:

  • A total of 2751 animals were sighted during 9 day period

  • 83 basking sharks were sighted

  • 13 ferry and cruise companies participated

  • 18 species of cetacean recorded

THANKS!

The ORCA team would like to extend our thanks to our OceanWatch partners and all people and organisations involved in ORCA OceanWatch 2017.

Our volunteer surveyors

ORCA volunteers have freely given their time and effort to generate the citizen science which is the foundation of this report. They have all done so with the selfless objective of creating a more complete picture of our whales, dolphins and porpoises, so that they can be afforded greater protection and conservation where this is required. One of the notable findings of their research has been the fluid and transitory nature of whale and dolphin populations, in terms of geography, the seasons, location of prey species and so on.

We anticipate just as much change and movement in the future, and look forward to welcoming new generations of volunteers to map the mercurial habits and life cycles of these mysterious animals.

A very special thank you
