Capture of Female Loggerhead Turtle Recorded from Space

27.08.2004


Scientists leading an international effort to safeguard the future of endangered loggerhead turtles have this week watched the capture and demise of one of their turtles being tracked by satellite.

“Sodade”, a loggerhead sea turtle from the republic of Cabo Verde, an island archipelago off the coast of Western Africa, appears to have been captured by fishermen.

She is one of 9 turtles being tracked by satellite from the recently discovered loggerhead nesting population in Cape Verde, which is 2nd only to Florida in the Atlantic and is the most important site in West Africa.



Each time the tracked turtles surface to breathe, their transmitting units connect with orbiting satellites and send radio transmissions that allow their position to be calculated. As discovered this week, this can also allow us to monitor their capture from space.

“We started to receive an unusually large number of very high quality locations from ´Sodade´- the 3rd turtle to be tracked in this study” said Dr. Brendan Godley, NERC Research Fellow with the Marine Turtle Research Group of the University of Exeter in Cornwall, UK.

“Such signals are received when a turtle spends large amounts of time at the surface suggesting she was likely on the deck of a boat and we became suspicious. Two days ago, transmissions ceased, suggesting that her transmitter has been removed and dumped. Given the large number of turtles captured for food in Cape Verde and the presence of fishing boats in the area at the time, we think we know her fate.”

Funded by several funding bodies in the United Kingdom and the USA1, the project is a collaboration between the Marine Turtle Research Group2, Project Cabo Verde Natura 20003, the Instituto Nacional Desenvolvimento das Pescas4 and the Canarian Institute of Marine Science5 and will collect some of the most important data for this species to date. The project is being backed by US based NGO SEATURTLE.ORG6 and recognising its importance, WWF West Africa Programme are supporting the project with dissemination of results as part of their capacity building initiatives in the region www.panda.org

SEATURTLE.ORG www.seaturtle.org/ is providing real-time public access to this project with live maps of the turtles’ tracks provided online. Members of the public are invited to follow the movements of these turtles on a daily basis: www.seaturtle.org/tracking/?project_id=26

“We have over 100,000 visits to our satellite tracking pages at www.seaturtle.org/tracking each month with the public marvelling at the migratory endeavours of these amazing creatures.” Dr. Michael Coyne, Director of SEATURTLE.ORG and research scientist at Duke University outlined. “It’s a pity that we have tracked the demise of one of the turtles in this case.”

Cape Verde hosts the most important nesting population of loggerhead sea turtles in Africa. “This unfortunate incident highlights the need for greater enforcement of existing protective legislation for loggerhead turtles in Cape Verde but the perennial problem as in many developing nations is the lack of resources available to biodiversity protection agencies.” Said Luis-Felipe Lopez-Jurado, Cape Verde Project Director for the Canarian Institute of Marine Science and Professor at the Universidad Las Palmas, Gran Canaria. “Such measures will be vital to ensure Cape Verdeans are able to enjoy loggerhead turtles long into the future”.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
