Fifty shades of brown

Combining sediment coring and a coffee break (contamination free) during the "Arctic Ocean 2016" expedition. As part of the sediment coring team, I was involved in describing, measuring and sampling the contents of over 110 meters of core. Brown was the dominant theme, though shades of greys, yellows, greens, pinks and blues, plus black, were also observed. Sites included the Amundsen Basin, Yermak Plateau, Alpha Ridge and Lomonosov Ridge and the cores may have sampled sediments back to Marine Isotope Stage 6, around 200,000 years ago.
