Mobile Oceanographic Data Collection and Animal Tracking Platform Launched

26.06.2012
A Wave Glider unmanned maritime vehicle (UMV) has been deployed by Ocean Tracking Network (OTN) researchers in the Gulf of St. Lawrence to test mobile collection and remote offloading of marine animal tracking information.

Deployed from Stephenville, N.L., Canada on June 19, the Wave Glider will travel in the area of the Strait of Belle Isle and the Cabot Strait over a 30-day period before reaching its final waypoint at the northern tip of Cape Breton Island.

The Wave Glider, built by U.S. based Liquid Robotics, harvests energy from wave motion and solar panels to generate thrust at the ocean's surface. Piloted by the Liquid Robotics team, the Glider carries a VEMCO acoustic receiver to collect detections of tagged fish within 800m. Of particular interest on this trip are detections of Atlantic salmon tagged by the Atlantic Salmon Federation.

Mobile receivers greatly expand the range of animal detections contributing to more comprehensive records of animal movement, migration and survival. In the future, Gliders will be able to upload data from fixed receiver stations eliminating the need to hire costly ships for data retrieval by OTN researchers. This mission is testing the ability of a mobile receiver and will not collect data from bottom moored receivers.

“These things have excellent station keep capabilities. You can take a Wave Glider and literally park it over a [receiver]. On this mission it’ll be moving all the time, but if we want to use it in the future to upload receivers, you would just tell it, ‘go here,’ and it would stay there for however long it takes to upload the data. If there’s a problem and it takes two or three days to upload the data, the glider doesn’t care. The whole time it’s uploading [data], it can be sending it to you via satellite. When it’s done with that one, it just moves on to the next one.” – Richard Davis, Technical Director for the Dalhousie Glider Group

Researchers are also collecting ocean surface parameters as a context for animal movement and migration.

“The scientific community has little oceanographic data available in general for the location of the mission at this time of year for use in developing models of the oceanography and currents in the Gulf. The models are important for weather prediction, search and rescue activities, understanding the drivers of the ecosystem, and for environmental responses to events like oil spills.” – Dr. Fred Whoriskey, Executive Director of OTN

OTN is a $168-million research and technology development project headquartered at Dalhousie University. Starting in 2008, OTN began deploying Canadian state of the art acoustic receivers and oceanographic monitoring equipment in key ocean locations. These are being used to document the movements and survival of marine animals carrying acoustic tags and to document how both are influenced by oceanographic conditions. OTN is funded by the Canada Foundation for Innovation and the Natural Sciences and Engineering Research Council of Canada.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
