MERIAN from Warnemünde, Germany to St. John's, Canada. It contains suspended particulate matter, particulate organic matter and particulate inorganic matter measurements [mg/l] from water samples collected from the seawater supply (Reinseewassersystem, RSWS) to calibrate the turbidity data of the RSWS system. The outflow of a PocketFerrybox that was connected to the seawater supply in the hangar was used for sampling. It takes a substantial amount of time for the water to reach the hanger from the intake point. The time delay between the sensor readings of the RSWS and the PocketFerrybox was determined and the timestamps of the water sampling were adjusted accordingly. Given latitute and longitude refer to this corrected timestamp. The original time of water sampling in the hangar is given as an additional column with the comment time of sampling. 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 -80 °C until gravimetric analysis in the laboratory at ICBM, Wilhelmshaven according to IOCCG recommendations.-48.5633911.4800549.7829959.16683
