Unheard of Encounter with Elusive Dolphins in the Channel

21.02.2008
Biscay Dolphin Research Programme (BDRP) & its affiliate encounter two large pods of Risso’s Dolphin in the English Channel

On a return crossing from Biscay through the English Channel in February, BDRP and its affiliated Spanish research organisation AMBAR (Sociedad para Estudio y la Conservacion de la Fauna Marina) encountered an unusual sight – two separate large groups of Risso’s Dolphin. This particular species of dolphin tends to be encountered sporadically by BDRP in small groups of 2 – 6 animals over deep waters in Biscay.

BDRP Research Director, Dr Tom Brereton, commented: “In over 13 years of research in the Channel and Biscay, BDRP have never before recorded Risso’s Dolphin in the group sizes encountered this month.

The first group numbered 26 and included 4 young dolphins, the second group, which was observed further into the Channel, numbered 40 dolphins. BDRP Chairman Clive Martin said: “Both groups seemed to be travelling from North to South and may have been part of a mass migration from colder, more northerly waters”.

This species has a unique appearance; pale grey-coloured, robust, blunt headed dolphins with a prominent dorsal fin and lacking a beak. They are often highly scarred due to fighting between individuals and tend to be more sedate than other dolphins.

BDRP researcher and PR Officer, Adrian Shephard commented: “Risso’s Dolphin are frequently encountered off the Welsh coastline and in the Irish sea by our affiliated research organisation and charity; SeaTrust”. Cliff Benson who heads SeaTrust records this species from both land and sea-based surveys, but again in relatively small groups.

BDRP continues to monitor the Channel and Biscay for a re-appearance of these large groups of Risso’s Dolphin together with other species with the aim of understanding their behaviour, movements and the threats they face.

About the Biscay Dolphin Research Programme (BDRP)
Marinelife has been monitoring whales and dolphins, seabirds and other marine life in the English Channel and European Atlantic continuously for thirteen years through one of its main projects, the Biscay Dolphin Research Programme (BDRP) using ferries as research platforms for monthly surveys. In addition, a BDRP full-time Wildlife Officer collects daily data on whale and dolphin abundance. Data from such long-term surveys give an accurate picture of changes in the status of whale and dolphin populations and their behaviour within the survey areas, thus far recording more than 20 species of whale and dolphin. They also highlight threats they face over time. www.biscay-dolphin.org.uk

About Marinelife

Marinelife is a Charitable Limited Company established to co-ordinate and develop a growing portfolio of global research and monitoring projects. Through these we aim to further the conservation of the wildlife of coasts and oceans through scientific investigation and educational activities. Marinelife continues to work in partnership with a number of other research groups, spearheading an international initiative, the Atlantic Research Coalition (ARC) that aims to describe changes in the status of whales and dolphins at a European scale.

Im Focus: Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: An energy-efficient way to stay warm: Sew high-tech heating patches to your clothes

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
