Global warming leading to alarming recession of the Arctic sea-ice cover: Insights from remote sensing observations and model reanalysis

open access: yesHeliyon, 2020
The present study quantifies the magnitude of Arctic sea-ice loss in the boreal summer (July–September), especially in September at different timescales (daily, monthly, annual and decadal).

Comparison on vertical distribution of pelagic copepod abundance, biomass and community structure between Atlantic and Pacific sector of the Arctic Ocean [PDF]

open access: yes, 2018
Recently, a great reduction of sea ice coverage has been reported for the Arctic Ocean during summer. The reduction has been reported to be greater for regions which connect the Arctic with the Atlantic and the Pacific Ocean, respectively.

Taking stock of arctic sea ice and climate [PDF]

open access: yes, 2009
The relationship among the cause-and-effect of the Arctic atmosphere, sea ice, and ocean is discussed. The increased vulnerability of the Arctic system to anomalous atmospheric forcing can be argued from the perspective that recent ice loss is the result

Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

open access: yesThe Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.

The imprint of anthropogenic CO2 in the Arctic Ocean: evidence from planktic δ13C data from watercolumn and sediment surfaces [PDF]

open access: yes, 2000
δ13C values of N. pachyderma (sin.) from the water column and from core top sediments are compared in order to determine the 13C decrease caused by the addition of anthropogenic CO2 to the atmosphere.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Constraining CMIP6 simulations for Atlantic Water in the Arctic using an AMOC-SST index

open access: yesFrontiers in Climate
Atlantic Water plays a key role in future changes in the Arctic Ocean. It contributes to Atlantification by transporting salt and heat within the Arctic Ocean basins. Many studies also attribute the amplified warming of the Arctic Ocean to an increase in

Investigation of Electrolyte Salts in Non‐Flammable Triethyl Phosphate for Sodium‐Ion Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
This study evaluates five sodium electrolyte salts (NaBF₄, NaClO₄, NaDFOB, NaFSI, NaPF₆) in triethyl phosphate (TEP) for sodium‐ion full‐cells, focusing on their physicochemical properties, solvation structure, and electrochemical performance. The addition of 1 wt.% vinylene carbonate (VC) improves cycling performance, with NaFSI demonstrating 88 ...

Current Events [PDF]

open access: yes
This lesson on the cause of currents and water circulation in the Arctic Ocean will require students to investigate the influence of salinity and temperature on the density of seawater to determine what factors drive water circulation in the Arctic Ocean.
