East Abaco survey
For the month of June BMMRO was based out of Hope Town in East Abaco with a goal of obtaining photo-id and biopsy samples from
beaked whales outside the Great Bahama Canyon, to understand whether these animals are part of the same population or a different stock.
Over 2,000 km were covered in 17 days of effort, resulting in 66 sightings of 11 different species, including 3 beaked whale species, and
the collection of 57 biopsy samples, 42 of which were from beaked whales.
This survey has produced an unprecedented number of beaked whale tissue samples in a short amount of time. These data will be useful
to answer the question of how beaked whales from different areas in the Northern Bahamas are related genetically, and will increase our understanding of
foraging ecology of the 3 beaked whale species found in the Bahamas.
