Abstract Highly branched isoprenoids (HBIs) in marine sediments have emerged as promising semi‐quantitative proxies to reconstruct seasonal sea ice in polar oceans. In this work, we examine the distribution of sympagic HBIs (IP25 and HBI‐II), pel

Decreasing sea ice extent caused by climate change is affecting the carbon cycle of the Arctic Ocean. In this study, surface sediments across the western Arctic Ocean are investigated to characterize sources of sedimentary organic carbon (OC). Bulk o

During the 3rd Chinese National Arctic Research Expedition cruise in the summer of 2008, nutrients (NO3, NO2, SiO32 , and PO43 ) and dissolved oxygen were measured in the western Arctic Ocean, to derive the vertical distribution of nutrient tracers a

Arctic Ocean properties and processes are highly relevant to the regional and global coupled climate system, yet still scarcely observed, especially in winter. Team OCEAN conducted a full year of physical oceanography observations as part of the Mult

Nutrient data were collected along similar cross-basin transects in the Canada Basin (75°–85°N) in 2005–2008, to evaluate the long-term change in the nitrate deficit. The results revealed a subsurface N* minimum (
