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 …

Temporal and geographic extent of the late Holocene dry period in the central Great Basin, USA
We provide evidence from pollen and radiocarbon dating of wet meadow sediments for the
presence of multi-centennial drought, termed the Late Holocene Dry Period (LHDP), in the …

Recent summer warming in northwestern Canada exceeds the Holocene thermal maximum
Eastern Beringia is one of the few Western Arctic regions where full Holocene climate
reconstructions are possible. However, most full Holocene reconstructions in Eastern …

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 …

Polar bear's range dynamics and survival in the Holocene
Polar bear (Ursus maritimus) is the apex predator of the Arctic, largely dependent on sea-
ice. The expected disappearance of the ice cover of the Arctic seas by the mid 21st century …

Pacific Decadal Oscillation-like variability at a millennial timescale during the Holocene
C Chen, W Zhao, X Zhang - Global and Planetary Change, 2021 - Elsevier
Sea surface temperatures (SSTs) in the North Pacific exert a great influence on global
climate and ecosystem changes. The Pacific Decadal Oscillation (PDO) is the leading mode …

An assessment of biomarker-based multivariate classification methods versus the PIP25 index for paleo Arctic sea ice reconstruction
The development of various combinative methods for Arctic sea ice reconstruction using the
sympagic highly branched isoprenoid (HBI) IP 25 in conjunction with pelagic biomarkers has …

Sedimentary records of bulk organic matter and lipid biomarkers in the Bering Sea: A centennial perspective of sea-ice variability and phytoplankton community
In this study, organic geochemical analyses of two sediment cores (BL16 and LV63–23)
recovered from the western Bering Sea were carried out to examine the sea-ice variability …
