VOLUNTEER whale and dolphin watchers are needed to scan the south coast seas this summer.

Reports of dolphins in Brighton Marina and Portsmouth Harbour have already been logged by the Sea Watch Foundation, a marine conservation charity and research organisation.

They are hoping for more sightings during their annual National Whale and Dolphin Watch, which takes place this year during August 12-20.

Anyone who will be near the coast that week can take part in the Watch by joining experienced observers at key look-out points on cliff-tops and harbours, or by making their own observations and sending them to Sea Watch.

The charity uses the information gathered to aid its research into marine mammal numbers and the effects of rising sea temperatures, fishing activities and pollution.

Last year's event produced 576 sightings, including a group of six fin whales the largest group ever seen in British waters.

Times, dates and details of co-ordinators will be published soon on the Sea Watch website www.seawatchfoundation.org.uk.
