Sea Level Variation Study Using GPS and an Ice Profiling Sonar
Dr. David Holland of New York University, in collaboration with Dr. Natalya Gomez at McGill University, is leading an investigation of sea level variations in the Disko Bay region of western Greenland. A shore-based system compares the direct arrival of GPS signals to the signals reflected off the sea surface to obtain sea level. The presence of sea ice and icebergs complicate the measurements. A shore-mounted camera provides information about the surroundings and the presence of sea ice and icebergs when there is daylight. Underwater sonar devices can supplement the camera-based

Tritech Sensor Selected for Student AUV
Tritech’s Micron sonar has been selected for the latest academic Autonomous Underwater Vehicle (AUV). The acoustic design team at McGill Robotics, McGill University, Montreal, Canada, chose to incorporate a mechanical scanning sonar into their new build AUV. The team now plans to integrate the Micron sonar into their software system in order to assist close range positioning and detect objects in low visibility environments. The team has also updated their AUV with new thrusters and are carrying out modifications to the frame and the pressure vessels. The Tritech Micron

a depth of 6,000m in the Caribbean which produced “the first images of micro-organisms at that depth and that degree of resolution,” said Jones. The equipment’s ability to withstand extremes was tested when it was later used in a project in the Canadian Arctic under the ice with McGill University of Montreal, to image Arctic springs to see if there was life in those springs. “We imaged quite a lot of bacteria and life forms in that [project],” Jones said. A large area of interest for Resolution Optics is the oil and gas industry where the company feels it is well suited
