Deployment of an Ice-Tethered Profiler with bio-optical suite. Field engineers rig a tripod to lower a 850m cable through the ice with a weight attached to the end. The ITP is attached to the cable and a final check is performed to ensure that the profiler's program is correct. The bio-optical sensor suite for measuring phytoplankton abundance and other optical properties is visible at the top of the profiler.
