FloeNet: A Mass‐Conserving Global Sea Ice Emulator That Generalizes Across Climates

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We introduce FloeNet, a graph neural network trained to emulate the Geophysical Fluid Dynamics Laboratory global sea ice model, SIS2. FloeNet is a mass‐conserving model, emulating 6‐hr mass and area budget tendencies related to sea ice and snow‐on‐sea‐ice growth, melt, and advection.

Habitat selection by two beluga whale populations in the Chukchi and Beaufort seas.

PLoS ONE, 2017
There has been extensive sea ice loss in the Chukchi and Beaufort seas where two beluga whale (Delphinapterus leucas) populations occur between July-November.

A Pulse of Meteoric Subsurface Fluid Discharging Into the Chukchi Sea During the Early Holocene Thermal Maximum (EHTM)

Geochemistry, Geophysics, Geosystems, 2021
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 ...

A Sea Ice Entrapment Event in the Southern Chukchi Sea: Analysis and Prediction

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Amplified Arctic warming is reducing sea ice cover, which is driving an increase in geopolitical interest in the region as it offers the possibility of reducing shipping times between Asia, Europe, and eastern North America, at the risk of increased ice hazards. Here, we examine the case of the Norseman II research ship that was trapped by sea

Distribution of living benthic foraminifera in the northern Chukchi Sea [PDF]

arktos, 2018
Living (Rose Bengal stained) benthic foraminifera were studied in the topmost sediments of five multi- and box cores collected on the continental shelf, upper and lower slopes, of the Chukchi Sea to provide background information on modern benthic foraminiferal distribution, useful for future studies.

How to Predict the Phase Shift of “Warm Arctic–Cold Eurasia” Pattern Between Early and Late Winter?

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The “Warm Arctic−Cold Eurasia” (WACE) pattern frequently undergoes distinct phase reversals between early and late winter, posing significant challenges for climate prediction. Current state‐of‐the‐art real‐time prediction models exhibit limited skill in forecasting WACE reversals, and the main reason is poor representation of key atmospheric ...

Basin‐Wide Shift in Bowhead Whale Migration in the Pacific Arctic

Geophysical Research Letters
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 ...

Trends in Aquatic Environmental DNA Research in Alaska

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Environmental DNA (eDNA) analysis is an emerging tool with significant potential to advance biomonitoring, particularly in remote and logistically challenging environments. To evaluate the state of eDNA research in Alaska, we conducted a literature review and a regional survey and results provide the first comprehensive overview of eDNA research in ...

Revisiting the status of the Arctic's Last Ice Area as a refuge for marine predators

Ecosphere, Volume 17, Issue 7, July 2026.
Abstract The Last Ice Area (LIA), located north of the Canadian Arctic Archipelago and Greenland, has the Arctic's oldest and thickest sea ice. The LIA is hypothesized to be a potential climate refuge for ice‐dependent top predators as Arctic sea ice continues to decline.

Regional Variations in Sea Ice and Primary Productivity in the Bering Sea During Marine Isotope Stage 11

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Marine Isotope Stage (MIS) 11 (424–374 ka) has long been an analog for Holocene climate because it is the most recent interglacial period with similar orbital conditions. However, there is global and regional variability in the climate response to MIS 11 warmth.
