Exeter scientist reveals secrets of Scotland’s basking sharks in new report

Seas between the islands of Skye and Mull on Scotland’s west coast are highly important for basking sharks, according to a report published by Scottish Natural Heritage (SNH).

Each year large numbers of basking sharks are seen in an area of the Sea of the Hebrides which is currently being assessed as part of the Scottish Marine Protected Areas Project.

The report sets out findings from the first two years of a project which aims to reveal some of the mysteries surrounding the world’s second largest fish. The project is a joint venture between SNH and the University of Exeter, and is the first known to use satellite tagging technology to track the near real-time movements of basking sharks. (more…)

Satellite tracking identifies Atlantic Ocean risk zones for leatherback turtles

The last large populations of the leatherback turtle are at risk because their migratory routes in the Atlantic Ocean clash with the locations of industrial fisheries, a new study shows.

Researchers used data from satellite transmitters attached to the turtles to track their movements across the Atlantic Ocean. These movements were then overlapped with information on high pressure fishing areas to identify where the turtles are most susceptible to becoming entangled and where they may drown. (more…)

First Satellite Tag Study for Manta Rays Reveals Habits And Hidden Journeys of Ocean Giants

Using the latest satellite tracking technology, conservationists from the Wildlife Conservation Society, the University of Exeter and the Government of Mexico have completed a ground-breaking study on a mysterious ocean giant: the manta ray.

The research team has produced the first published study on the use of satellite telemetry to track the open-ocean journeys of the world’s largest ray, which can grow up to 25 feet in width.

Researchers say the manta ray—listed as ‘Vulnerable’ by the International Union for the Conservation of Nature (IUCN)—has become increasingly threatened by fishing and accidental capture and now needs more protection. (more…)

Epic Journeys of Turtles Revealed

The epic ocean-spanning journeys of the gigantic leatherback turtle in the South Atlantic have been revealed for the first time thanks to groundbreaking research using satellite tracking. 

Experts at the Centre for Ecology and Conservation (Cornwall) at the University of Exeter led a five-year study to find out more about these increasingly rare creatures and inform conservation efforts.  (more…)
