AWI Moored ULS Data, Weddell Sea (1990-1998)

View Catalog Page

Entry ID

G01359

Summary

This data set consists of moored Upward Looking Sonar (ULS) data from 14 stations in the Weddell Sea. Parameters in the processed data files are water pressure, water temperature, draft, and a flag to indicate if the instrument is under ice. Raw data files contain additional parameters. These data were contributed by the Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany, in 1999. Data are available via ftp.

Quality

After processing the raw data as described in the documentation that accompanies the data set, and assuming Gaussian distribution of erros, the total resulting error in ice draft measurements is about 4 cm (Strass, 1998).
