Abstract:The article presents the detailed analysis results considering bottom sediments from the Chukchi Sea. Two core samples, b16 and НС-8 were taken from the northern Herald Canyon 150 km northeast from NE Wrangel Island. Core b16 has been studied in more detail. According to the 210 Pb measurements, the recent sedimentation rate amounts to 0.9 mm/y-1 at the sampling point. In the bottom layer of the core sample, the minimum concentrations of biogenic components (SiO2bio, Corg, Ntot, and Br) and the increased conce… Show more
