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 mooring’s 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 Programme’s 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.
