Unprecedented decline of Arctic sea ice outflow in 2018

Nature Communications, 2022
Fram Strait is the major gateway connecting the Arctic Ocean and North Atlantic Ocean, where nearly 90% of the sea ice export from the Arctic Ocean takes place.

A Synthesis of the Upper Arctic Ocean Circulation During 2000–2019: Understanding the Roles of Wind Forcing and Sea Ice Decline

Frontiers in Marine Science, 2022
Major changes have occurred in the Arctic Ocean during 2000–2019, including the unprecedented spin-up of the Beaufort Gyre and the emergence of Arctic Atlantification in the eastern Eurasian Basin.

Disentangling the Coupled Atmosphere‐Ocean‐Ice Interactions Driving Arctic Sea Ice Response to CO2 Increases

Journal of Advances in Modeling Earth Systems, 2020
A novel decomposition of the ocean heat energy that contributes to sea ice melt and growth (ocean‐ice and frazil heat) into components that are driven by surface heat flux and ocean circulation changes is used to isolate the evolving roles of the ...

A model study of the first ventilated regime of the Arctic Ocean during the early Miocene [PDF]

Polar Research, 2012
The tectonic opening of Fram Strait during the Neogene was a significant geological event that transferred the Arctic Ocean from a poorly ventilated enclosed basin, with weak exchange with the North Atlantic, to a fully ventilated “ocean stage ...

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 ...

The Cenozoic palaeoenvironment of the Arctic Ocean [PDF]

Nature, 2006
The history of the Arctic Ocean during the Cenozoic era (0-65 million years ago) is largely unknown from direct evidence. Here we present a Cenozoic palaeoceanographic record constructed from >400 m of sediment core from a recent drilling expedition to the Lomonosov ridge in the Arctic Ocean.

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 ...

Ocean Arc: An Ocean Shot for the Arctic

Marine Technology Society Journal, 2021
Abstract Photography can be a powerful instrument for change. Combining scientific research, new imaging technologies equipped with Artificial Intelligence, and underwater photography, we'll share near- to real-time changes of biodiversity in the Arctic and highlight these rapidly changing and unique environments.

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.
