Tagged turtles in the eye of the storm?

22.09.2003


A NERC-funded researcher is tracking a number of migrating marine turtles which could be sent off-course or washed ashore by Hurricane Isabel. Updates on the turtles’ progress can be followed on the web.



Dr Brendan Godley and colleagues from the University of Exeter are using satellite technology to track the endangered green and loggerhead turtles as they leave their nesting beaches in North Carolina and the Cayman Islands and start the long journey to their winter foraging grounds. They attach satellite transmitters to the turtles’ shells and each time a turtle surfaces to breathe, the transmitter sends signals to satellites which calculate its position. The transmitter can also provide information on the depth and duration of dives, giving an insight into where and how turtles forage for food.

Says Dr Godley, “We started tracking the turtles to find out where they live when they are not breeding. Locating the foraging sites of marine turtle populations is vital if we are to protect them. But now some of them off the coast of the USA are actually experiencing Hurricane Isabel and it’s possible they could be forced out to sea or even washed ashore.”


By tracking the turtles, Dr Godley expects to discover whether the female turtles, once they have laid their eggs, choose migration routes to minimise either the distance travelled or the time spent away from food. The information coming back from the sensors should also indicate the influence of ocean currents on the turtles’ behaviour and if the turtles move to warmer waters to find food in winter or simply enter a state of semi-hibernation.

Dr Godley has collaborated with colleagues at Seaturtle.org, a web-based organisation in the USA, to set up a website enabling people to follow the progress of the turtles.

Each of the tagged turtles has been named so anyone logging on to the website at www.seaturtle.org/tracking can see where their favourite turtle has been and what it has been doing. The site has so far proved very popular with schoolchildren in the Cayman Islands who are following turtles they have called Myles, Shelby and Samia.

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
