Source-specific biomarkers as proxies for Arctic and Antarctic sea ice
ST Belt - Organic geochemistry, 2018 - Elsevier
Over the last decade or so, certain source-specific C 25 highly branched isoprenoid (HBI)
lipid biomarkers have emerged as useful proxies for Arctic and Antarctic sea ice. Thus, IP 25 …

Holocene sea subsurface and surface water masses in the Fram Strait–Comparisons of temperature and sea-ice reconstructions
Two high-resolution sediment cores from eastern Fram Strait have been investigated for sea
subsurface and surface temperature variability during the Holocene (the past ca 12,000 …

Group 2i Isochrysidales produce characteristic alkenones reflecting sea ice distribution
Alkenones are biomarkers produced solely by algae in the order Isochrysidales that have
been used to reconstruct sea surface temperature (SST) since the 1980s. However …

Holocene variability in sea ice cover, primary production, and Pacific‐Water inflow and climate change in the Chukchi and East Siberian Seas (Arctic Ocean)
In this study, we present new detailed biomarker‐based sea ice records from two sediment
cores recovered in the Chukchi Sea and the East Siberian Sea. These new biomarker data …

Identification of paleo Arctic winter sea ice limits and the marginal ice zone: optimised biomarker-based reconstructions of late Quaternary Arctic sea ice
Abstract Analysis of> 100 surface sediments from across the Barents Sea has shown that the
relative abundances of the mono-unsaturated sea ice diatom-derived biomarker IP 25 and a …

Enhanced Arctic sea ice melting controlled by larger heat discharge of mid-Holocene rivers
Arctic sea ice retreat is linked to extrapolar thermal energy import, while the potential impact
of pan-Arctic river heat discharge on sea-ice loss has been unresolved. We reconstructed …

Does Arctic warming reduce preservation of organic matter in Barents Sea sediments?
Over the last few decades, the Barents Sea experienced substantial warming, an expansion
of relatively warm Atlantic water and a reduction in sea ice cover. This environmental …

Variability in drift ice export from the Arctic Ocean to the North Icelandic Shelf over the last 8000 years: a multi-proxy evaluation
North Iceland represents a climatically sensitive region, in part, due to its location at the
confluence of southward flowing and drift ice-laden polar waters from the Arctic Ocean …

[HTML][HTML] A novel biomarker-based proxy for the spring phytoplankton bloom in Arctic and sub-arctic settings–HBI T25
The spring phytoplankton bloom is a characteristic feature of mid-high latitudes in modern
times, but can be challenging to identify in palaeo records. In the current study, we …
