Abstract:

This data set comprises unprocessed CTD data collected during the RV ALKOR cruise AL539 conducted in July 2020 (July 5th to July 18th 2020) in the Western Baltic Sea by the University of Hamburg. The cruise was part of the 5-year MARSYS teaching cruise program of the University of Hamburg GFP20-1_047. The cruises are designed to train students in sampling methods targeting the different compartments of a marine ecosystem. The CTD data was obtained directly from the Sea & Sun Technology software. No quality control of the data has been done.

Comment:

The data still contains outliers, and therefore negative values of water depth.
