Seasonal grain-size measurements of surface sediments off Svalbard ...

All sediment samples were obtained from four stations close to the coast and within 1 km distance to each other (station 5: 78.11°N 14.35°E; station 6: 78.10°N 14.38°E; station 7: 78.10°N 14.38°E; station 23: 78.10°N 14.39°E) in Isfjorden, Svalbard, Arctic Ocean. The sampling was performed with a Va...

Description
Summary:All sediment samples were obtained from four stations close to the coast and within 1 km distance to each other (station 5: 78.11°N 14.35°E; station 6: 78.10°N 14.38°E; station 7: 78.10°N 14.38°E; station 23: 78.10°N 14.39°E) in Isfjorden, Svalbard, Arctic Ocean. The sampling was performed with a Van Veen grab deployed from R/V Farm. Six repeated sediment sampling campaigns took place between December 2017 and September 2019 (for further details see Miksch et al. 2020) Particle-size measurements were performed in the Particle-Size Laboratory at MARUM, University of Bremen with a Beckman Coulter Laser Diffraction Particle Size Analyzer LS 13320. Prior to the measurements, the samples were boiled with approximately 0.3 g tetra-sodium diphosphate decahydrate (Na~4~P~2~O~7~ * 10H~2~O, 3 min) to destroy aggregates. Sample preparation and measurements were carried out with deionized, degassed and filtered water (filter mesh size: 0.2 µm) to reduce the potential influence of gas bubbles or particles within the ...
