AWI Moored ULS Data, Greenland Sea and Fram Strait, 1991-2002  View Catalog Page Entry ID
G02139
Summary
This data set consists of Upward Looking Sonar (ULS) data from 11 moorings in the Greenland Sea. Parameters in the processed data files include ice draft, water pressure, and water temperature. Raw data files with sonar travel time, and files with draft frequency of occurrence, are available as well. A single statistical file for each mooring summarizes that moorings record. These data were contributed by the Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany, in 2002 and 2004, as a contribution to the World Climate Research Programmes Arctic Climate System Study/Climate and Cryosphere (ACSYS/CliC) Project. Data are available via FTP.

Quality
Quality control for binary and ASCII data output files takes place as follows. Binary-data: Start time, sample time, time to water and time marks are controlled with rawuls.exe. Days with missing time marks are left out and binary data are converted to ASCII data with sepuls.c.
ASCII-data: Start and end time of lowdraftdata (the data acquired at 5 minute intervals) are controlled. Start and end time of highdraftdata (the data acquired at 10 second intervals for 25 minutes at 0000 and 1200 UTC) are controlled. Temperature and pressure data are plotted.
Access Constraints
None.
Use Constraints
None.
