Samples from the sea surface were collected twice a day using a Neuston catamaran equipped with a 20 µm mesh net, sampling the upper 20 cm of the water column. Corresponding reference samples from the underlying water (ULW) were collected at approximately 1 m depth using an ULW net. The biochemical composition of the particulate fraction was assessed through measurements of particulate organic carbon >20µm (POC>20µm), particulate amino acids >20µm (PAA>20µm), and particulate combined carbohydrates >20µm (PCCHO>20µm). POC was measured using an Euro EA elemental analyser. To determine the composition of the microphytoplankton community (>20 µm), samples were preserved with Lugol's solution and analyzed according to the Utermöhl method. Sampling stations were categorized based on the relative abundance of microphytoplankton (>20 µm) and nano- and picophytoplankton (≤20 µm).19.2376520.1722457.1872357.44991Baltic SeaGerman Research Foundationhttps://doi.org/10.13039/501100001659451574234FOR 5267 - Biogeochemical processes and Air-sea exchange in the Sea-Surface microlayer (BASS)
