Ferrybox underway observations of physical and optical surface water variables during HE626 from 2023-07-20 to 2023-08-09

The data presented here were collected during the cruise HE626 with RV Heincke from Bremerhaven to Bremerhaven (2023-07-20 to 2023-08-09). The water intake of the autonomous measurement system was in approx. 3 m depth. All data have been subjected to automated quality checks (see processing report) and visual control. The chlorophyll-a data were additionally calibrated by comparison with discrete samples. Details on all quality control steps and the calibration can be found in the data processing report. The resulting data set contains the quality-controlled data and corresponding quality flags. The data set contains data during transect and station. The rawdata are also available on request from the principal investigator.
