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.Nikki Beauchamp

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
