Absorption coefficients by coloured dissolved organic matter from the East Greenland Sea measured underway with a Liquid Waveguide Capillary Cell system during POLARSTERN cruise PS107

Water samples were taken during East Greenland expedition PS107 with RV Polarstern from 24 July to 18 August 2017. Water samples were collected from the ship's seawater supply pumped through teflon tubing from about 11m depth during underway as described in Liu et al (2018a). The same water samples were measured as in Liu et al. (2081b, 2019). Water samples for CDOM absorption analysis were filtered through 0.2 µm filters and analysed onboard with a 2 m path length liquid waveguide capillary cell system (LWCC, WPI) following Levering et al. (2017). Details on method adaptation to our instrumentation set-up are provided in Alvarez et al. (2022). Salinity data were extracted from https://doi.pangaea.de/10.1594/PANGAEA.889535.
