The SMBs measure alternatingly. While one box is measuring, the other one is being cleaned. The boxes switched every 24 hours at the beginning of the time series and from 17 Sep on every 6 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. Analysis of the chlorophyll-a and turbidity data during parallel operation of the sensors in the two boxes showed significant differences between the sensors (especially for turbidity, only small differences found for chlorophyll-a). The sensors were aligned resulting in fairly consistent chlorophyll-a and turbidity time series. A comparison for the corrected chlorophyll-a with satellite data using the GlobColour CHL1 product is provided. Correlation with CHL1 is moderate, considering only nighttime data which are assumed to be unaffected by non-photochemical quenching. Details on all quality control steps and the comparison with satellite data can be found in the data processing report. Note that the instruments are factory-calibrated, however, no post-calibration was performed due to missing reference data. Absolute values should be challenged. The time series shows clear signs of non-photochemical quenching, see data processing report. It was out of the scope of the quality control to flag or correct non-photochemical quenching. The resulting data set contains the original data and corresponding quality flags achieved by the quality control algorithm as well as the corrected chlorophyll-a and turbidity data with corresponding quality flags. 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.
