The disintegrated, inorganic grain-size distribution of sediment core GeoB19905-1 was determined every ten centimetres (and in parts higher resolution) to decipher patterns of sediment input to and transport on the southern west Greenland shelf. Prior to measurement, organic matter, calcium carbonate and biogenic silica were chemically removed from the bulk sediment. Measurements were then performed using a Beckman Coulter Laser Diffraction Particle Size Analyzer LS 13320.
