Abstract:	This dataset was collected during the cruise MSM139 with RV MARIA S. MERIAN from Reykjavik, Iceland to Reykjavik, Iceland. It contains suspended particulate matter, particulate organic matter and particulate inorganic matter measurements [mg/l] from water samples collected directly from the seawater supply (Reinseewassersystem, RSWS) to calibrate the turbidity data of the RSWS system. To obtain suspended particulate matter concentrations, water samples were filtered onboard through 0.7 μm pore size, glass fiber filters (Whatmann GF/F, 47 mm) under low vacuum. Filters were frozen immediately at -25 °C until gravimetric analysis in the laboratory at ICBM, Wilhelmshaven according to IOCCG recommendations.
