ITP 102 Deployment
Deployment operations
ITP 102 was the third buoy deployment of the MOSAiC expedition at the L3 site of the Distributed Network, consisting of WHOI ITP, SIMB, AOFB, and Met Sled. The ITP is outfitted with a Modular Acoustic Velocity Sensor (MAVS). Conditions were light snowfall with a mostly clear horizon, temperature of -10.5 C, 92% relative humitidy, air pressure of 1006.6 kPa, with a wind speed of 1 m/s. Ice drilling operations were conducted the day prior to deployments due to daylight restrictions. A 24” hole was bored using the Beaver hydraulic drill system. This size hole was needed to accommodate the fins which are added to the profiler body in order to keep the MAVS probe pointed into the current. The 24” hole was also needed for the Autonomous Ocean Flux Buoy.
All of the deployment gear was placed on the ice using the ship’s crane and an AWI owned 20’ container. After all of the gear was staged at the pre-drilled hole operations began. The profiler was clamped to the mooring wire and passed all inductive tests.
