Current measurements under ice face some challenges not present when measuring current in open water and water free of ice. There is the problem of getting the current meter through a hole in the ice, which limits the horizontal dimensions of the instrument package such as fins that might provide directional stability in open water. Then there is the issue of damage to the sensor from contact with...
Measurements of velocity structure in the water column under Arctic ice from an Ice-Tethered Profiler (ITP) employed an acoustic point-measurement current meter, MAVS (Modular Acoustic Velocity Sensor). With the velocity sensor it becomes the Ice-Tethered Profiler with Velocity (ITPV). The profiler, containing a Seabird CTD, MAVS, batteries, an inductive modem, and a wire crawling engine, integrated...
The Current Measurement Technology Committee or CMTC joined the IEEE Oceanic Engineering Society in the 10th year of that society and CMTC workshops have continued through its 9th workshop held in 2008. These workshops have documented with their published proceedings the rise of acoustic Doppler profiling, the appearance and later development of HF radar techniques for observing surface current, electromagnetic...
