Future Range Shifts and Diversity Patterns of Antarctic Lecideoid Lichens Under Climate Change Scenarios

Global Change Biology Communications, EarlyView.
Modeling of current and future spatial distribution of Antarctic lecideoid lichens shows that warming will strongly increase the potential habitat. Under three climate‐change scenarios, most fungal and algal partners are projected to expand inland. Overall, climate change drives widespread range shifts and promotes colonization of interior Antarctica ...

ENSO’s impact on linear and nonlinear predictability of Antarctic sea ice

npj Climate and Atmospheric Science
While the influence of ENSO on Antarctic sea ice variability is well-known, its role in sea ice predictability, both linear and nonlinear, remains unexplored.

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 ...

Thermal Responses to Antarctic Ice Shelf Melt in an Eddy-Rich Global Ocean–Sea Ice Model

Journal of Climate, 2020
The response of near-Antarctic waters to freshening by increased glacial melt is investigated using a high-resolution (0.1°) global ocean–sea ice model with realistic Antarctic water-mass properties.

The Ice of the Southern Ocean [PDF]

, 1967
Regular sea ice observations off the coasts of Antarctica in the Mirny Station area have been made by the Soviet Antarctic Expedition since 1956. For eight years air ice reconnaissance over the Davis Sea has been made from Mirny Station during all the ...

Acute and Chronic Toxicity of Sediments Containing Platinum and Palladium on Freshwater Benthic Organisms Chironomus riparius and Hyalella azteca

Journal of Applied Toxicology, EarlyView.
ABSTRACT The expanding demand for platinum group elements (PGEs) in industrial and medical applications has led to their increasing accumulation in aquatic sediments. However, their ecological impacts remain poorly understood, particularly for sediment‐dwelling invertebrates. This study assessed the toxicity of platinum (Pt) and palladium (Pd) across a

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

Hydrochemical Characteristics of Four Retreating Glacier Forefields Off the Coast of Admiralty Bay (King George Island, Maritime Antarctic): Diverse Sources of Metals and Metalloids

Land Degradation &Development, EarlyView.
ABSTRACT This study examines the impact of geological, marine and anthropogenic sources on metal and metalloid concentrations in the forefields of four glaciers (Ecology, Sphinx, Tower and Windy) on King George Island, Antarctic. Water samples were collected at the beginning and end of the hydrological season (austral summer, December 2021 to February ...

Last Interglacial subsurface warming on the Antarctic shelf triggered by reduced deep-ocean convection

Communications Earth & Environment
The Antarctic ice-sheet could have contributed 3 to 5 m sea-level equivalent to the Last Interglacial sea-level highstand. Such an Antarctic ice-mass loss compared to pre-industrial requires a subsurface warming on the Antarctic shelf of ~ 3 °C according

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 ...
