| Summary: | The presented data originates from the 1306cm long gravity core MSM45-19-2 (58°45.68 N, 61°56.25 W, 202m water depth) taken during R/V Maria S. Merian cruise MSM45 in August 2015 at 202 m water depth on the northern Labrador Shelf, northeast Canada, northwest Atlantic. Here, we present a high-resolution and well-dated sediment record from the northern Labrador Shelf that provides new evidence of the freshwater signature and the mechanisms involved in the Hudson Bay Ice Saddle collapse. Elemental composition and color reflectance data reveal sediment dispersal characteristic of the subglacial drainage of LAO. The light reflectance was measured in 1-cm intervals on the foil-covered, air-bubble-free, core surface with a hand-held Konica Minolta CM 600d spectrophotometer on board the research vessel. The spectrum of the reflected light was detected by a multi-segment light sensor at a 20 nm pitch between wavelengths of 400–700 nm. The a*(D65) value reflects the ratio of magenta (700 nm) and green (500 nm).The ... |
