The Association of Antarctic Sea Ice with the Subantarctic Mode and Antarctic Intermediate Waters during the Last Deglaciation

Proceedings, 2023
The Southern Ocean waters exchange freshwater, nutrients, carbon, heat, and salt to the Equator and influence the global carbon budget. Therefore, it is essential to understand the variations in Southern Ocean circulation during the last deglacial period

PLISMIP-ANT, an ice-sheet model intercomparison project [PDF]

, 2015
In the context of future climate change, understanding the nature and behaviour of ice sheets during warm intervals in Earth history is of fundamental importance.

A twenty-first century structural change in Antarctica’s sea ice system

Communications Earth & Environment
From 1979 to 2016, total Antarctic sea ice extent experienced a positive trend with record winter maxima in 2012 and 2014. Record summer minima followed within the period 2017-2024, raising the possibility that the Antarctic sea ice system might be ...

Moderate ocean alkalinity enhancement likely to have minimal effects on a habitat‐forming kelp across multiple life stages

Limnology and Oceanography, EarlyView.
Abstract Ocean alkalinity enhancement (OAE) is a widely considered marine CO2 removal method. Ocean alkalinity enhancement works by converting seawater CO2 into HCO3−$$ {\mathrm{HCO}}_3^{-} $$ and CO32−$$ {\mathrm{CO}}_3^{2-} $$ by electrochemical methods or the addition of alkaline minerals.

Combustion of available fossil-fuel resources sufficient to eliminate the Antarctic Ice Sheet [PDF]

, 2015
The Antarctic Ice Sheet stores water equivalent to 58 m in global sea-level rise. We show in simulations using the Parallel Ice Sheet Model that burning the currently attainable fossil fuel resources is sufficient to eliminate the ice sheet.

Nutrient‐dependent thermal response in growth and stoichiometry of Antarctic phytoplankton

Limnology and Oceanography, EarlyView.
Abstract Rising temperatures and altered nutrient supply are expected to influence future phytoplankton thermal performance and community dynamics. The thermal response of phytoplankton has been shown to be influenced by nutrient availability, but information is still limited, particularly for the coastal Southern Ocean.

Simulated Antarctic sea ice expansion reconciles climate model with observation

npj Climate and Atmospheric Science
Observations reveal Antarctic sea ice expansion and Southern Ocean surface cooling trends from 1979 to 2014, whereas climate models mostly simulate the opposite. Here I use historical ensemble simulations with multiple climate models to show that sea-ice

Decadal transformations of antarctic sea ice modes

Frontiers in Marine Science
In light of ongoing global warming and the accelerated melting of Antarctic sea ice, this study aims to analyze the recent changes in the principal modes of Antarctic sea ice over the past decade, utilizing Empirical Orthogonal Function (EOF) and ...

Influence of tropical Atlantic meridional dipole of sea surface temperature anomalies on Antarctic autumn sea ice

Environmental Research Letters, 2022
Antarctic sea ice plays an important role in polar ecosystems and global climate, while its variability is affected by many factors. Teleconnections between the tropical and high latitudes have profound impacts on Antarctic climate changes through the ...

Bio-inspired design of ice-retardant devices based on benthic marine invertebrates: the effect of surface texture [PDF]

PeerJ 2:e588 2014, 2014
Growth of ice on surfaces poses a challenge for both organisms and for devices that come into contact with liquids below the freezing point. Resistance of some organisms to ice formation and growth, either in subtidal environments (e.g. Antarctic anchor ice), or in environments with moisture and cold air (e.g.
