Winter sea ice edge shaped by Antarctic Circumpolar Current pathways Open
The Antarctic Circumpolar Current (ACC) is often considered a natural barrier for the northward expansion of the Antarctic sea ice, but the underlying processes remain little explored. Here, we focus on the main fronts of the ACC – as a me…

Anatomy of Arctic and Antarctic sea ice lows in an ocean–sea ice model Open
Sea ice has exhibited a number of record lows in both hemispheres over the past two decades. While the causes of individual sea ice lows have already been investigated extensively, no systematic comparison across events and hemispheres has…

Contribution of ocean processes to the drops in Antarctic sea ice extent at the end of the 1970s and after 2 Open
The Antarctic sea ice extent has displayed two large drops over the past 65 years, a small one at the end of the 1970s and a more substantial one after 2016. The atmospheric forcing provided a dominant contribution to those drops. Wind cha…

Does increased spatial resolution improve the simulation of Arctic sea ice lows in NEMO4.2-SI3? Open
The Arctic total sea ice extent has rapidly declined since the beginning of satellite observations. This decline materialized into record sea ice lows in the summers of 2007 and 2012. Those sea ice lows exhibit an important spatial heterog…

Baseline matters: Challenges and implications of different marine heatwave baselines Open
Marine heatwaves (MHWs), prolonged periods of unusually high ocean temperatures, significantly impact global ecosystems. However, there is ongoing debate regarding the definition of these extreme events, which is crucial for effective rese…

Drivers of Marine Heatwaves in the Arctic Ocean Open
Among the documented consequences of anthropogenic global warming are the increased frequency and duration of marine heatwaves in the global ocean. The literature dedicated to Arctic marine heatwaves corroborates those results, but fails t…

Underestimation of oceanic carbon uptake in the Arctic Ocean: ice melt as predictor of the sea ice carbon pump Open
The Arctic Ocean is generally undersaturated in CO2 and acts as a net sink of atmospheric CO2. This oceanic uptake is strongly modulated by sea ice, which can prevent air–sea gas exchange and has major impacts on stratification and primary…

Marine Heatwaves in the Arctic Ocean: drivers, feedback mechanisms and interactions with sea ice Open
Arctic regions are warming at a rate faster than the global average. Superimposed on this trend, marine heatwaves and other extreme events are becoming more frequent and intense. Simultaneously the sea ice phenology with which these events…

How does storage of carbon in sea ice impacts the partial pressure of CO 2 ?To answer this question, one can consider the upper layer of the ocean, partially covered by sea ice forming and melting.The atmospheric pCO 2 and wind speed at 10…
