Reconstructed warm season temperatures for Nome, Seward Peninsula, Alaska [PDF]
[1] Understanding of past climate variability in the Bering Strait region and adjacent land areas is limited by a paucity of long instrumental and paleoclimatic records.

Wind Forcing and Warm Water Upwelling in a Recurring Beaufort Shelf Polynya
Abstract The Beaufort Shelf has historically been reported to exhibit limited polynya activity in winter. Yet, recent satellite observations show episodic recurrence of a large polynya west of Mackenzie Canyon, a site of significant shelf‐basin exchange.

The response of Arctic Ocean biogeochemistry to subsurface flow driven by permafrost thaw is poorly understood. We present dissolved chloride and water isotopic data from the Chukchi Sea Shelf sediments that reveal the presence of a meteoric subsurface ...

Abstract Ice cores from Mt. Logan, the second highest peak in North America located in the St. Elias mountains in southwest Yukon, Canada, have provided conflicting accumulation records, thus the hydroclimate response to changing atmospheric conditions in the highest elevation regions is not well constrained.

A THREE-DIMENSIONAL MODEL OF BERING AND CHUKCHI SEA
A part of the continental shelf area of the Bering and Chukchi Sea are now being opened up for oil exploration. For engineering and ecological risk analyses, extensive field data collection efforts are being carried out by various United States agencies and petroleum corporations to understand the hydrodynamic behavior of this vast offshore area.

Basin‐Wide Shift in Bowhead Whale Migration in the Pacific Arctic
In a rapidly changing Arctic, multiple lines of evidence suggest that bowhead whale migration is changing. To explore these changes further, we used passive acoustic data to examine bowhead whale presence in the western Beaufort Sea (12 years) and ...

Mapping in the Arctic Ocean in Support of a Potential Extended Continental Shelf [PDF]
Under Article 76 of The United Nations Convention on the Law of the Sea (UNCLOS; U.N. 1997), coastal states may, under certain circumstances, gain sovereign rights over the resources of the seafloor and subsurface of “submerged extensions of their ...

Hypsometry and Volume of the Arctic Ocean and Its Constituent Seas [PDF]
This paper presents an analysis of the Arctic Ocean and its constituent seas for seafloor area distribution versus depth and ocean volume. The bathymetry from the International Bathymetric Chart of the Arctic Ocean (IBCAO) is used together with limits ...

Abstract Marine methane emissions are important components of natural methane budgets, but the methane emission contribution derived from the central Arctic is still unclear. Here, we measured the dissolved methane concentration and its stable carbon isotopic signature (δ13C‐CH4) while onboard a western Arctic cruise in 2024.
