Monosaccharide concentrations of particulate organic matter in samples collected during RV MARIA S. MERIAN cruise MSM95 to the Fram Strait, Arctic Ocean

During the Maria S. Merian cruise MSM95 to the Fram Strait in 2020, water samples were collected from nine stations using a CTD rosette sampler (SeaBird SBE 911Plus). Samples were collected at several depths. From each sample, 4 L of seawater was filtered onto a 0.7 µm GF/F filter using a peristaltic pump. The filters were immediately stored at -80 °C. From each of the filters, 2 x 11.2 mm circular pieces were removed and subject to acid hydrolysis (1 M HCI for 24 h at 100 °C). The aliquots were run in a speed vac before resuspension in MilliQ. Measurements of monosaccharides were obtained using High-performance anion exchange chromatography with pulsed amperometric detection along with standards.
