Record numbers of common dolphin sightings off Scotland’s west coast

Sightings of common dolphins across the Hebrides have reached a new record high according to research conducted by marine conservation charity, Hebridean Whale and Dolphin Trust.

Evidence collected during marine research expeditions on the Trust’s specialized research yacht Silurian in 2017 has revealed a dramatic 24% increase from the previous year’s already record-breaking figures.

The findings were made in a research season running from April to October 2017, part of the charity’s unique long-term citizen science project monitoring whales, dolphins and porpoises – collectively known as cetaceans – and basking sharks in the Hebrides.

“We have never documented so many sightings of common dolphins off Scotland’s west coast before. Our findings highlight the importance of on-going monitoring and research to strengthen our understanding of what is

As announced on TV’s BBC Countryfile last night, results of the 2017 National Whale and Dolphin Watch are in!

During last year’s event, which took place 29^th July – 6^th August, a record-breaking 1,529 hours of dedicated watches took place. Some 300 hours more than any previous occasion, this represents 2,500 volunteers all around the British Isles getting involved to report on the UK’s whale and dolphin species.

2017 was the sixteenth year that this huge citizen science scheme had taken place and clearly the event is building on popularity year on year. “It’s so important for people to join in helping us to track

Hebridean sightings soar for harbour porpoises but plunge for basking sharks

Harbour porpoise sightings off Scotland’s west coast increased by 25 per cent in 2014 compared to the previous year while sightings of basking sharks unexpectedly fell by 33 per cent, during marine research expeditions carried out by Hebridean Whale and Dolphin Trust.

 

The charity’s extensive research also revealed dramatic evidence of a shark attack on a member of an endangered group of killer whales thought to be the UK’s only resident population of orca.

With the United Kingdom’s only known resident population of killer whales at risk of imminent extinction, securing new information about this endangered group is one of the ambitions of a new season of marine research expeditions launched by Hebridean Whale and Dolphin Trust (HWDT) this month.

 

In its 20th anniversary year, HWDT is recruiting volunteers to work alongside marine scientists in surveys running from May to October, to gather crucial data on

Research surveys conducted by the Hebridean Whale and Dolphin Trust (HWDT) during 2013 have identified a remarkably wide range of whale, dolphin and porpoise species – highlighting the need to conserve the rich biodiversity and globally-important marine habitats in western Scotland’s seas.

The latest research is part of HWDT’s unique and long-term monitoring project of cetaceans – whales, dolphins and porpoises – in the Hebrides. With growing concerns over the state of the UK’s seas, and threats to wildlife and ecosystems from human activity, HWDT is calling for volunteers to help continue the pioneering research in 2014.

In total during 2013, HWDT recorded more than 400 encounters with cetaceans and basking sharks, and made almost 1,000 underwater detections of cetaceans using specialist listening equipment.

Kerry Froud, HWDT Biodiversity Officer, said: “The impressive range of species of cetaceans and basking sharks that we have documented this year highlights the wealth of marine life in Scotland’s west coast ocean environment – and the importance of ensuring the continued

The Hebridean Whale and Dolphin Trust (HWDT) has announced details of its 2013 surveys, in which volunteers and marine scientists will carry out pioneering research into the lives of whales, dolphins and porpoises off Scotland’s west coast.

The surveys – carried out from the charity’s research yacht Silurian between May and September – will gather data on the numbers and behaviour of whales, dolphins and
