description |
International audience Paleo-climate proxy records documenting sea-ice extent are important sources of information to assess the time of emergence and magnitude of on-going changes in the Arctic Ocean and better predict future climate and environmental evolution in that region. In this study, a suite of geochemical tracers including total organic carbon (TOC), total nitrogen (TN), carbon/nitrogen ratio (C/N), stable isotope composition of organic carbon and nitrogen (δ 13 C, δ 15 N), and phytoplankton biomarkers (highly branched isoprenoids (HBIs) and sterols) were measured in a marine sediment core to document the sea-ice variability in the Chukchi Sea since the beginning of the Industrial Era. The downcore profile of the sea-ice proxy HBIs suggests a transition from extensive sea ice in the late 19th century to Marginal Ice Zone (MIZ) in AD 1930-1990s and then moderate sea-ice cover since 1990s. Rising of all HBI abundances between AD 1865-1875 indicate a transient retreat of summer ice edge off the shelf followed by a return to near-perennial sea ice till 1920-1930 as revealed by the absence of HBIs and brassicasterol. Sea ice retreat occurred again in AD 1920-1930 and followed by colder decades in 1940s-1960s before a sustained decline since the 1990s. The downcore profile of C/N, δ 13 C of organic matter and sterols indicates a gradual increase of terrigenous inputs accelerating during the most recent decades likely due to enhanced fluvial run-off and sediment transport by sediment-laden sea ice. Concomitantly, increasing δ 15 N values suggest limited nutrient utilization due to enhanced stratification of the surface ocean caused by increased freshening. The role of the Arctic Oscillation (AO), the Pacific Decadal Oscillation (PDO) and Atlantic Multidecadal Oscillation (AMO) are discussed to explore potential drivers of the observed sea-ice changes. |
