Sea-level driven isolation of glacial plant refugia revealed by submerged lake sediment from the Bering Land Bridge and St. Matthew Island Open
Bering Land Bridge (BLB) climate and vegetation during the Last Glacial Maximum (LGM) remains largely understudied, given challenges associated with collecting records from the submerged BLB. Previous records, confined to the margins of th…

Bølling‐Allerød Productivity in the Subarctic Pacific Driven by Seasonal Upwelling Open
The Bølling‐Allerød deglacial event is marked by high diatom productivity and opal deposition throughout the subarctic Pacific. This opal could either constitute a strengthened biological pump and thus carbon sequestration, or a weakened b…

Ecological response to anthropogenic climate change in the Beaufort Sea: Biennial-scale evidence from proxy and instrumental records during the last ~70 years Open
We analyzed ostracode and foraminifera assemblages, silicoflagellates, biogenic silica, and sediment grain size from two high-resolution box cores collected in the Alaska and Canadian Beaufort Sea during the 2022 Arctic Challenge for Susta…

Twentieth century extreme precipitation detected in a high-resolution, coastal lake-sediment record from California Open
California faces increasing economic and societal risks from extreme precipitation and flooding associated with atmospheric rivers (ARs) under projected twenty-first century climate warming. Lake sediments can retain signals of past extrem…

Ice and ocean constraints on early human migrations into North America along the Pacific coast Open
Founding populations of the first Americans likely occupied parts of Beringia during the Last Glacial Maximum (LGM). The timing, pathways, and modes of their southward transit remain unknown, but blockage of the interior route by North Ame…

Logging data are measurements of physical properties of the formation surrounding a borehole, acquired in situ after completion of coring (wireline logging) or during drilling (Logging-While-Drilling, LWD). The range of data (resistivity, …

Sediment controls dynamic behavior of a Cordilleran Ice Stream at the Last Glacial Maximum Open
The uncertain response of marine terminating outlet glaciers to climate change at time scales beyond short-term observation limits models of future sea level rise. At temperate tidewater margins, abundant subglacial meltwater forms moraina…

Oceanographic and Climatic Change in the Bering Sea, Last Glacial Maximum to Holocene Open
Post‐glacial sea level rise led to a direct connection between the Arctic and Pacific Oceans via the Bering Strait. Consequently, the Bering Sea experienced changes in connectivity, size, and sediment sources that were among the most drast…
