Dear all,
The online version of the following paper is now available:
DISTRIBUTION, ENCOUNTER RATES ND HABITAT CHARACTERISTICS OF TOOTHED CETACEANS
IN THE BAY OF BISCAY AND ADJACENT WATERS FROM PLATFORM-OF-OPPORTUNITY DATA.
ICES Journal of Marine Science, 64.
Abstract
Data on the distribution and habitat utilization of oceanic marine mammals are
difficult to collect and yet such information is beneficial for many
conservation and management purposes. Data collected during ferry-based
cetacean surveys in the English Channel and Bay of Biscay between 1998 and 2002
were analysed to investigate the distribution, encounter rate, and habitat
characteristics of toothed cetaceans there. In all, 17 873 nautical miles were
surveyed, and 1008 encounters of 13 identified species, including delphinids,
ziphiids, harbour porpoise, and sperm whale, were recorded. The common dolphin
was the commonest species, followed in decreasing occurrence by striped and
bottlenose dolphins, pilot whale, harbour porpoise, Cuvier's beaked whale, and
sperm whales. The distribution of harbour porpoises was restricted to the
shallow waters of the western English Channel. Common and bottlenose dolphins
were distributed mainly over the continental shelf, although there were some
encounters along the shelf edge and in the open ocean. Striped dolphins and
pilot whales were sighted in oceanic waters in the central and southern Bay of
Biscay. Cuvier's beaked whales and sperm whales were recorded in the deep
oceanic waters of the southern Bay of Biscay. Bathymetry clearly plays a
significant role in the distribution and habitat partitioning of toothed
cetaceans in the region.
