Whales,
dolphins and porpoises are to be photographed and their calls recorded during a
new survey of marine life off Scotland 's
west coast.
Scientists and
volunteers will gather the data between May and September.
The Hebridean
Whale and Dolphin Trust (HWDT) project will also seek to record behaviour and
numbers of basking sharks.
The survey
work will be carried out over seven to 10 days from the charity's yacht,
Silurian.
HWDT said 24
species of cetaceans - whales, dolphins and porpoises - can be found off Scotland 's west
coast, including species designated as national and international conservation
priorities.
The survey
will involve photographing dorsal fins for use in identifying individual
animals and to improve understanding of species' movements and interactions.
Photo
identification work has already catalogued 125 minke whales, some of which HWDT
believe stay in Hebridean seas all year round.
