Abstract:
Concentrations of Chlorophyll a from special sampling events during the MOSAiC (PS122) drift expedition in the central Arctic Ocean. 0.3-4L of water were filtered onto precombusted GF/F filters (nominal pore size 0.7µm) and frozen at -80°C. Samples were subsequently extracted in 90°C acetone,homogenized using a cell mill, and measured on the following day using a Turner flourometer, followed by an acidification step to determine pheopigments (see Knap et al. 1994 for details and calculations). Samples were collected between October 2019 and October 2020.
