From 2002 to 2005 a FerryBox system was installed aboard two different ferries traveling between Cuxhaven (GE) and Harwich (UK) on a daily basis. The FerryBox system is an automated flow-through monitoring system for measuring oceanographic and biogeochemical parameters installed on ships of opportunity. The variables were recorded in a time interval of 10-20 seconds corresponding to a spatial resolution of about 100m. The dataset provides the parameters water temperature, salinity, dissolved oxygen and chlorophyll-a fluorescence. There is a longer data gap between November 2002 and August 2003 in the time series due to a change of the vessel in October 2002.

This dataset contains the ferrybox records of the ferry Cuxhaven-Harwich between 2002-03-01 and 2005-10-25. Salinity, temperature, dissolved oxygen and chlorophyll of 679 sections are provided in NetCDF-format. From a total of 741 sections, 62 sections are missing due to fail operation of the salinometer.
