Changes in the oxygen isotope composition of the Bering Sea contribution to the Arctic Ocean are an independent measure of increasing freshwater fluxes through the Bering Strait. [PDF]

PLoS ONE, 2022
A large volume of freshwater is incorporated in the relatively fresh (salinity ~32-33) Pacific Ocean waters that are transported north through the Bering Strait relative to deep Atlantic salinity in the Arctic Ocean (salinity ~34.8).

Sea ice directs changes in bowhead whale phenology through the Bering Strait [PDF]

Movement Ecology, 2023
Background Climate change is warming the Arctic faster than the rest of the planet. Shifts in whale migration timing have been linked to climate change in temperate and sub-Arctic regions, and evidence suggests Bering–Chukchi–Beaufort (BCB) bowhead ...

Closure of the Bering Strait caused Mid-Pleistocene Transition cooling [PDF]

Nature Communications, 2018
The causes of Mid-Pleistocene Transition global cooling 1 million years ago are still unknown. Here, the authors find the subarctic North Pacific became stratified during these glaciations due to closure of the Bering Strait, which would have removed CO2

Shifting stage‐specific constraints on productivity shape recovery potential for Yukon River Chinook salmon [PDF]

Ecol Appl
Abstract Identifying key life history periods in which population productivity is constrained represents a persistent challenge in conservation and natural resource management. For species with complex life cycles, such as Pacific salmon (Oncorhynchus spp.), population dynamics may be shaped by interactions between natural and anthropogenic impacts ...

Using colored dissolved organic matter fluorescence to trace Pacific-derived water in the Eastern Canadian Arctic [PDF]

Scientific Reports
Low-salinity Pacific Water (PW) entering the Arctic Ocean through the Bering Strait is the second largest source of freshwater to the Arctic Ocean and dominates the freshwater inventory of Baffin Bay due to PW advection through Nares Strait and the ...

Post-glacial flooding of the Bering Land Bridge dated to 11 cal ka BP based on new geophysical and sediment records [PDF]

Climate of the Past, 2017
The Bering Strait connects the Arctic and Pacific oceans and separates the North American and Asian landmasses. The presently shallow ( ∼  53 m) strait was exposed during the sea level lowstand of the last glacial period, which permitted human ...

Arctic and Sub‐Arctic Mechanisms Explaining Observed Increasing Northward Flow Through the Bering Strait and Why Models May Be Getting It Wrong

Geophysical Research Letters, 2023
The Pacific oceanic input to the Arctic via the Bering Strait (important for western Arctic ice retreat, water properties, and nutrient supply) has been increasing for three decades.

Seasonal distribution of short-tailed shearwaters and their prey in the Bering and Chukchi seas [PDF]

Biogeosciences, 2017
The short-tailed shearwater (Ardenna tenuirostris) is one of the abundant marine top predators in the Pacific; this seabird spends its non-breeding period in the northern North Pacific during May–October and many visit the southern Chukchi Sea in August ...

Freshwater routing in eddy-permitting simulations of the last deglacial: the impact of realistic freshwater discharge [PDF]

Climate of the Past, 2021
Freshwater, in the form of glacial runoff, is hypothesized to play a critical role in centennial- to millennial-scale climate variability, such as the Younger Dryas and Dansgaard–Oeschger events, but this relationship is not straightforward.

Interannual Variability of Salinity in the Chukchi Sea and Its Relationships with the Dynamics of the East Siberian Current during 1993–2020

Remote Sensing, 2023
The interannual features of the salinity in the Chukchi Sea during the ice-free period of a year are investigated on the base of Soil Moisture Active Passive (SMAP) satellite measurements and GLORYS12v1 reanalysis data.
