Data processing notes

Data were processed and calibrated by AWI. Statistical summaries were computed and reformatted by R. Lindsay, PSC from the point data which ranged fro 0.5 to 15 minutes, depending on the mooring.

The summary files have the statistics for

  • water temperature
  • instrument depth
  • sea ice draft.

One mooring, AWI206, has what appear to be a lot of ice bergs (or bad data) with drafts up to 100m. We have removed any draft greater tham 30 m in computing the draft statistics. The uncorrected (for sea level) ULS draft values are included in the point data set but are not included in the summary file.

Number of samples

12,533,581 point values, 757 monthly averages
