An Unprecedented Sea Ice Retreat in the Weddell Sea Driving an Overall Decrease of the Antarctic Sea‐Ice Extent Over the 20th Century

Geophysical Research Letters, 2023
Sea‐ice extent is predicted to decrease in a warming climate. However, despite global warming over the past century, total Antarctic sea ice remained relatively stable from 1979 until 2015, before strongly melting.

Reconstructing Antarctic winter sea-ice extent during Marine Isotope Stage 5e [PDF]

Climate of the Past, 2022
Environmental conditions during Marine Isotope Stage (MIS) 5e (130–116 ka) represent an important “process analogue” for understanding the climatic responses to present and future anthropogenic warming. The response of Antarctic sea ice to global warming

An indicator of sea ice variability for the Antarctic marginal ice zone

The Cryosphere, 2022
Abstract. Remote-sensing records over the last 40 years have revealed large year-to-year global and regional variability in Antarctic sea ice extent. Sea ice area and extent are useful climatic indicators of large-scale variability, but they do not allow the quantification of regions of distinct variability in sea ice concentration (SIC).

A review of bacterial disease outbreaks in rainbow trout (Oncorhynchus mykiss) reported from 2010 to 2022

Journal of Fish Diseases, EarlyView., 2023
Abstract Outbreaks of bacterial infections in aquaculture have emerged as significant threats to the sustainable production of rainbow trout (Oncorhynchus mykiss) worldwide. Understanding the dynamics of these outbreaks and the bacteria involved is crucial for implementing effective management strategies. This comprehensive review presents an update on

Snow on Antarctic sea ice

Reviews of Geophysics, 2001
Snow on Antarctic sea ice plays a complex and highly variable role in air‐sea‐ice interaction processes and the Earth's climate system. Using data collected mostly during the past 10 years, this paper reviews the following topics: snow thickness and snow type and their geographical and seasonal variations; snow grain size, density, and salinity ...

Antarctic sea ice decline delayed well into the 21st century in a high-resolution climate projection [PDF]

, 2020
Despite ongoing global warming and strong sea ice decline in the Arctic, the sea ice extent around the Antarctic continent has not declined during the satellite era since 1979.

Characterization factors for ocean acidification impacts on marine biodiversity

Journal of Industrial Ecology, Volume 26, Issue 6, Page 2069-2079, December 2022., 2022
Abstract Rising greenhouse gas emissions do not only accelerate climate change but also make the ocean more acidic. This applies above all to carbon dioxide (CO2). Lower ocean pH levels threaten marine ecosystems and especially strongly calcifying species.

Sources of low-frequency variability in observed Antarctic sea ice [PDF]

The Cryosphere
Antarctic sea ice has exhibited significant variability over the satellite record, including a period of prolonged and gradual expansion, as well as a period of sudden decline.

Modeled Trends in Antarctic Sea Ice Thickness [PDF]

Journal of Climate, 2014
Abstract Unlike the rapid sea ice losses reported in the Arctic, satellite observations show an overall increase in Antarctic sea ice concentration over recent decades. However, observations of decadal trends in Antarctic ice thickness, and hence ice volume, do not currently exist.

Reduced ageing in the frozen state in the tardigrade Milnesium inceptum (Eutardigrada: Apochela)

Journal of Zoology, Volume 318, Issue 4, Page 253-259, December 2022., 2022
Tardigrades were subjected to subzero temperature treatment by cooling on agar plates from room temperature down to ‐30°C. The specimens were kept for seven days at ‐30°C without temperature fluctuations, after which the animals were allowed to slowly warm. Live and dead animals were recorded after thawing.
