Benthic-pelagic relations of aquatic organisms in various water masses of the Chukchi Sea by the data of δ¹⁵N and δ¹³С

Известия ТИНРО, 2021
To compare trophic characteristics for pelagic and benthic communities of zooplankton and zoobenthos in the Chukchi Sea, isotopic composition of carbon and nitrogen (δ15N and δ13С) was measured in two different water masses: i) the Bering Sea water with ...

Absorption and backscattering in the Beaufort and Chukchi Seas

Journal of Geophysical Research: Oceans, 2005
Bio‐optical observations were made during August 2000 in the Beaufort and Chukchi Seas. Chlorophyll a concentration (Chl) ranged from 0.068 to 18.5 mg chl m−3. Both total particulate and phytoplankton absorption at 443 nm were closely correlated with chlorophyll concentration.

N2O dynamics in the western Arctic Ocean during the summer of 2017

Scientific Reports, 2021
The western Arctic Ocean (WAO) has experienced increased heat transport into the region, sea-ice reduction, and changes to the WAO nitrous oxide (N2O) cycles from greenhouse gases.

Primary production in the Chukchi Sea with potential effects of freshwater content [PDF]

Biogeosciences, 2016
The in situ primary production rates and various environmental variables were investigated in the Chukchi Sea during the RUSALCA expedition, which was conducted in 2012, to identify the current status of primary production.

Nitrogen Limitation of the Summer Phytoplankton and Heterotrophic Prokaryote Communities in the Chukchi Sea

Frontiers in Marine Science, 2018
Major changes to Arctic marine ecosystems have resulted in longer growing seasons with increased phytoplankton production over larger areas. In the Chukchi Sea, the high productivity fuels intense benthic denitrification creating a nitrogen (N) deficit ...

Changes in gray whale phenology and distribution related to prey variability and ocean biophysics in the northern Bering and eastern Chukchi seas.

PLoS ONE, 2022
Changes in gray whale (Eschrichtius robustus) phenology and distribution are related to observed and hypothesized prey availability, bottom water temperature, salinity, sea ice persistence, integrated water column and sediment chlorophyll a, and patterns

Oceanic Routing of Wind-Sourced Energy Along the Arctic Continental Shelves

Frontiers in Marine Science, 2020
Data from coastal tide gauges, oceanographic moorings, and a numerical model show that Arctic storm surges force continental shelf waves (CSWs) that dynamically link the circumpolar Arctic continental shelf system. These trains of barotropic disturbances

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 ...

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.
