Great White Shark RFID/Satellite Tracking Shows Long Journeys, Many Beach Visits 86

Lucas123 writes "Marine biologists from OCEARCH, a non-profit shark research project, have been tagging scores of great whites and other shark species with an array of wireless technologies, gathering granular data on the sharks over the past year or more. For example, Mary Lee, a great white shark that's the same weight and nearly the same length as a Buick, was tagged off of Cape Cod and has made beach visits up and down the U.S. East Coast and Bermuda. She came so close to beaches that the research team alerted local authorities. The team attaches an array of acoustic and satellite tags as well as accelerometers to the sharks, which collect more than 100 data points every second — 8.5 million data points per day. The data has provided a detailed, three-dimensional view of the shark's behavior, which the team has been sharing in real time on its website. OCEARCH plans to expand that data sharing over the next few weeks to social networks and classrooms."

    Analog Devices has an expanding portfolio of Embedded Processors, DSPs and Analog Microcontrollers for a wide variety of general-purpose and application-specific needs.

    Blackfin, SHARC, SigmaDSP, TigerSHARC, ADSP-21xx and Precision Analog Microcontrollers a broad range of functions including high speed, multi-DSP signal processing, converged signal/control processing, fixed-function processing and microcontroller applications.

    The SHARC® Processor family dominates the floating-point DSP market with exceptional core and memory performance and outstanding I/O throughput. For as little as 319 MFLOPS/dollar, SHARC brings floating-point processing performance to applications where dynamic range is key.

    Thusly, SHARC data is actually procured by Analog Devices product in a straightforward fashion and then is sent to the satellites in orbits over earth. Locations are found frequently near beaches and such.

    It's interesting that it swims in a wide circle that includes Bermuda. How did it navigate to the island?

    It uses GPS. Didn't you read TFA?
