General Sediment Chemical Composition The major element composition of Chukchi Sea sediments (Figure 3) is related to grain size (Figure 4), with the separation of terrigenous materials by mineral content occurring during their transport by currents (Viscosi-Shirley et al, 2003; Astakhov et al, 2013a)
The use of paleoceanographic proxies as indicators of sea ice conditions must take into consideration the geological environment and hydrochemical conditions of near-bottom water
Summary
The Arctic is a key region for the study of the global consequences of Pacific Arctic climate change. Instrumental measurements cover only the last 60–100 years, a time period that is insufficient to take into account major climate change cycles. To obtain more reliable results requires using climate change proxies that permit reconstruction of the paleoenvironment over much longer time periods. Sediment cores contain the most continuous archives of paleoenvironmental changes, so they are essential for these reconstructions. Such reconstructions for the East Siberian Sea shelf are complicated because of the paucity and poor preservation of biological remains, including the carbonates, which are needed for paleoproductivity and paleoenvironment studies in deeper parts of the Arctic Ocean (Polyak et al., 2004; de Vernal et al, 2005). The possibilities of using other proxies, such as siliceous microfossils and lithological and geochemical information from the sediments, were lacking prior to the RussianAmerican Long-term Census of the Arctic (RUSALCA) program
