Report on the geomorphological survey in the Soya Coast (JARE-61)

Antarctic Record, 2020
The Antarctic Ice Sheet is a major source of future sea-level rise due to global warming. Reconstruction of the past Antarctic Ice Sheet is essential to understand the mechanism of the Antarctic Ice Sheet response to global and regional climate changes ...

Microalgal community structure and primary production in Arctic and Antarctic sea ice: A synthesis

, 2018
Sea ice is one the largest biomes on earth, yet it is poorly described by biogeochemical and climate models. In this paper, published and unpublished data on sympagic (ice-associated) algal biodiversity and productivity have been compiled from more than ...

Impacts of Antarctic summer sea-ice extremes

PNAS Nexus
Abstract Antarctic sea ice plays many crucial roles in the physical environments and ecosystems of Antarctica and the Southern Ocean. In this study, we synthesize the physical, biogeochemical, ecosystem, and societal impacts of summers with extreme low Antarctic sea-ice coverage.

Bark‐associated yeasts and their potential role as tree carbon sink at the treeline of the southern Andes

Plant Biology, EarlyView.
In the southern Andes, Nothofagus pumilio shows elevational decreases in the concentrations of carbon reserves which are the food of bark‐associated yeasts, suggesting that competition for carbohydrates between tree growth and bark‐associated yeasts may cause carbon shortages.

Improved Simulation of Antarctic Sea Ice by Parameterized Thickness of New Ice in a Coupled Climate Model

Geophysical Research Letters
Sea ice formation over open water exerts critical control on polar atmosphere‐ocean‐ice interactions, but is only crudely represented in sea ice models. In this study, a collection depth parameterization of new ice for flux polynya models is modified by ...

Spring–summer albedo variations of Antarctic sea ice from 1982 to 2009

Environmental Research Letters, 2015
This study examined the spring–summer (November, December, January and February) albedo averages and trends using a dataset consisting of 28 years of homogenized satellite data for the entire Antarctic sea ice region and for five longitudinal sectors ...

Projected Antarctic sea ice change contributes to increased occurrence of strong El Niño

npj Climate and Atmospheric Science
Current climate models suggested that Antarctic sea ice cover would decrease substantially under cumulative CO2 emission, but little is known whether large decrease in Antarctic sea ice can influence the occurrence of strong El Niño.

Atmospheric influences on the anomalous 2016 Antarctic sea ice decay

, 2017
. In contrast to the Arctic, where total sea ice extent (SIE) has been decreasing for the last three decades, Antarctic SIE has shown a small, but significant, increase during the same time period.

Anatomy of Arctic and Antarctic sea ice lows in an ocean–sea ice model

The Cryosphere
Sea ice has exhibited a number of record lows in both hemispheres over the past two decades. While the causes of individualsea ice lows have already been investigated, no systematic comparison across events and hemispheres has been conductedin a consistent framework yet.
