Lasting impact of winds on Arctic sea ice through the ocean's memory [PDF]

The Cryosphere, 2021
In this paper we studied the impact of winds on Arctic sea ice through the ocean's memory by using numerical simulations. We found that the changes in halosteric height induced by wind perturbations can significantly affect the Arctic sea ice drift ...

Stability of the arctic halocline: a new indicator of arctic climate change

Environmental Research Letters, 2018
In this study, we propose a new Arctic climate change indicator based on the strength of the Arctic halocline, a porous barrier between the cold and fresh upper ocean and ice and the warm intermediate Atlantic Water of the Arctic Ocean.

Mercury isotope evidence for Arctic summertime re-emission of mercury from the cryosphere

Nature Communications, 2022
Arctic warming thaws permafrost, leading to enhanced soil mercury transport to the Arctic Ocean. Mercury isotope signatures in arctic rivers, ocean and atmosphere suggest that permafrost mercury is buried in marine sediment and not emitted to the global ...

An inventory of Arctic Ocean data in the World Ocean Database [PDF]

Earth System Science Data, 2018
The World Ocean Database (WOD) contains over 1.3 million oceanographic casts (where cast refers to an oceanographic profile or set of profiles collected concurrently at more than one depth between the ocean surface and ocean bottom) collected in the ...

The Ocean Carbon Cycle in the Western Arctic Ocean: Distributions and Air-Sea Fluxes of Carbon Dioxide [PDF]

Oceanography, 2011
The Arctic Ocean is a potentially important sink for atmospheric carbon dioxide (CO2) with a recent estimate suggesting that the region contributes from 5 to 14% of the global ocean's net uptake of CO2.

The Law of the Sea and the Arctic Ocean

Arctic Review on Law and Politics, 2011
Rather than proposing new legal instruments for addressing the contemporary significant changes of the Arctic Ocean, both the 2008 Ilulissat Declaration and the 2010 Chelsea ministerial meeting reaffirm the five Arctic coastal States’ commitment to the ...

Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots

Advanced Materials, EarlyView.
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Warmer Atlantic Water intrusion energizes the Arctic Eurasian Basin

Communications Earth & Environment
Climate warming is expected to weaken ocean circulation by suppressing deep-ocean eddy activity at mid and low latitudes. However, the future evolution of deep-ocean dynamics in the rapidly changing Arctic remains unclear.

Future Arctic Climate Change in CMIP6 Strikingly Intensified by NEMO‐Family Climate Models

Geophysical Research Letters, 2023
Climate change in the Arctic has substantial impacts on human life and ecosystems both within and beyond the Arctic. Our analysis of CMIP6 simulations shows that some climate models project much larger Arctic climate change than other models, including ...

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

Advanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...
