Abstract:
Underway optical chlorophyll-a and turbidity data were collected along the cruise track with Sea-Bird Scientific ECO FLNTU sensors installed within two autonomous measurement systems, called self-cleaning monitoring boxes (SMBs). The SMBs measure alternatingly. While one box is measuring, the other one is being cleaned. The boxes switched generally every 24 hours. The water inlet for the SMBs is at about 4 m below sea surface. Observed chlorophyll-a and turbidity data were both quality controlled and a comparison for chlorophyll-a with satellite data using the GlobColour CHL1 and CHL2 products is additionally provided. Note that the instruments are factory-calibrated, however no post-calibration was performed due to missing reference data. Details on all quality control steps and the comparison with satellite data can be found in the data processing report. The resulting data set contains the original data and corresponding quality flags achieved by the quality control algorithm. The data source is given through the name of the active SMB. The data set contains data during transit time and station work. We recommend to use ship's speed to filter for only transit data.
