Mineral and grain size data for sediment core MD99-2317

Core MD99-2317 was taken from the Grivel Basin, East Greenland ) (68.103°N, 27.8615°W, 536 m wd, 25.07 m long), offshore from the 60,000 km2 early Tertiary basalt outcrop, and from an area subjected to the transport of icebergs from local and regional tidewater glaciers. Radiocarbon dates for this core are reported in Jennings et al (2011). Grain size analysis of the 240 µm), volume % of sand, and measures of the sortable silt % and the mean sortable silt grain size, which can be correlated with changes in the flow speed of bottom currents . Tables 3 and 4 report replicate runs on X-ray diffraction estimates of mineral weight % and Malvern-based grain size volume % for a series of 7 paired samples (A versus B) taken across the 10-cm diameter core in order to investigate the variability of six non-clay and clay minerals and six grain size variables in adjacent samples. Between sample Analysis-of-Variance on the data set indicated only a limited number of statistically significant differences.
