Mooring and Drifting Buoy Data: Beaufort Gyre Freshwater Experiment, 2003

They collected temperature time series, salinity, current, sea ice draft, and bottom pressure measurements. Investigators used conventional mooring systems containing a McLane Moored Profiler (MMP) to sample currents and hydrographic data from 50 m to 2050 m with 17-hour time intervals.

They measured sea ice draft with an ASL Environmental Sciences 420 kHz upward-looking sonar (ULS). Using a high accuracy bottom pressure recorder (BPR), they measured sea level height variability and near-bottom seawater temperatures. Each mooring consisted of a surface floatation package at 50 m depth, which housed the ULS, a mooring cable containing the MMP, and dual acoustic releases and a BPR located immediately above the anchor.
