The 25th Annual Conference of the European Cetacean Society took place in Cadiz, Spain, from 21st to 23rd March 2011. The theme of the conference was Long-term datasets on marine mammals: learning from the past to manage the future.

Diane Claridge, BMMRO's director, presented a talk:
Comparing Abundance and Turnover of Blainville's Beaked whales at a Navy Range and a Control Site in the Bahamas.
Authors: Diane Claridge, Leigh Hickmott, Charlotte Dunn, John Durban

This work shows that a similar number of whales are found at the AUTEC range and off south Abaco on an annual basis, but that there is a slightly higher rate of turnover of whales at AUTEC (turnover means whales leaving and new whales arriving) which may be related to the frequency use of sonar.

Charlotte Dunn presented a poster:
Photographic resightings show philopatry in a male Blainville's beaked whale.
Authors: Charlotte Dunn, Leigh Hickmott, John Durban, Diane Claridge

This work tracks a male beaked whale off south Abaco from the time of birth to maturity and shows that males may remain in the area where they were born throughout their lifetime. (see poster below)
