Ozone depletion events observed in the high latitude surface layer during the TOPSE aircraft program [PDF]

open access: yes, 2003
During the Tropospheric Ozone Production about the Spring Equinox (TOPSE) aircraft program, ozone depletion events (ODEs) in the high latitude surface layer were investigated using lidar and in situ instruments.

The reversibility of sea ice loss in a state-of-the-art climate model [PDF]

open access: yes, 2011
Rapid Arctic sea ice retreat has fueled speculation about the possibility of threshold (or ‘tipping point’) behavior and irreversible loss of the sea ice cover. We test sea ice reversibility within a state-of-the-art atmosphere–ocean global climate model

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.

A circumpolar perspective on fluvial sediment flux to the Arctic ocean [PDF]

open access: yes, 2002
Quantification of sediment fluxes from rivers is fundamental to understanding land‐ocean linkages in the Arctic. Numerous publications have focused on this subject over the past century, yet assessments of temporal trends are scarce and consensus on ...

Climate Change and China as a Global Emerging Regulatory Sea Power in the Arctic Ocean: Is China a Threat for Arctic Ocean Security? [PDF]

open access: yes, 2015
The impact of climate change in the Arctic Ocean such as ice melting and ice retreat facilitatesnatural resources extraction. Arctic fossil fuel becomes the drivers of geopolitical changes in theArctic Ocean.

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 ...

On the Increasing Importance of Air-Sea Exchanges in a Thawing Arctic: A Review

open access: yesAtmosphere, 2018
Forty years ago, climate scientists predicted the Arctic to be one of Earth’s most sensitive climate regions and thus extremely vulnerable to increased CO2. The rapid and unprecedented changes observed in the Arctic confirm this prediction.

Researchers explore Arctic freshwater\u27s role in ocean circulation [PDF]

open access: yes, 2000
A critical, but insufficiently understood, component of global change is the influence of Arctic freshwater input on water mass exchange between the Arctic Ocean and Atlantic and Pacific Oceans.

Arctic Ocean tidal constituents atlas

open access: yes, 2023
Ocean tides are a vital component of global ocean circulation, with their role in the Arctic Ocean being crucial for ocean and sea ice dynamics. Recently, significant advances have been made in global ocean tide models, however, difficulties remain in the coastal regions as well as in the higher latitudes.

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 ...
