Quantification of ikaite in Antarctic sea ice [PDF]

open access: yesAntarctic Science, 2012
AbstractCalcium carbonate precipitation in sea ice is thought to potentially drive significant CO2 uptake by the ocean. However, little is known about the quantitative spatial and temporal distribution of CaCO3 within sea ice, although it is hypothesized that high quantities of dissolved organic matter and/or phosphate (common in sea ice) may inhibit ...

An Assessment of the Antarctic Sea Ice Mass Budget Simulation in CMIP6 Historical Experiment

open access: yesFrontiers in Earth Science, 2021
The sea ice formation and dissipation processes are complicated and involve many factors and mechanisms, from the basal growth/melting, the frazil ice formation, the snow ice processes to the dynamic process, etc. The contribution of different factors to

Recent changes in Antarctic Sea Ice [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
In contrast to the Arctic, total sea ice extent (SIE) across the Southern Ocean has increased since the late 1970s, with the annual mean increasing at a rate of 186×10 3  km 2 per decade (1.5% per decade; p <0.01) for 1979–2013.

The Influence of Antarctic Sea Ice Distribution on the Southern Ocean Overturning Circulation for the Past 20,000 Years

open access: yesProceedings, 2023
Changes in Southern Ocean physics are dynamically linked to westerly winds, ocean currents, and the distribution of Antarctic sea ice in the Southern Hemisphere.

Antarctic Sea Ice--a Habitat for Extremophiles [PDF]

open access: yesScience, 2002
The pack ice of Earth's polar oceans appears to be frozen white desert, devoid of life. However, beneath the snow lies a unique habitat for a group of bacteria and microscopic plants and animals that are encased in an ice matrix at low temperatures and light levels, with the only liquid being pockets of concentrated brines. Survival in these conditions

Using a combination of midazolam and butorphanol is a safe and effective reversible field sedation protocol for Weddell seal (Leptonychotes weddellii) pups

open access: yesVeterinary Record, Volume 191, Issue 11, 3/10 December 2022., 2022
Abstract Background Weddell seals (Leptonychotes weddellii) are a well‐studied species of phocid with an apparent sensitivity to immobilising agents. Mortality as high as 31% has been reported during field immobilisation. This study investigated the use of a benzodiazepine in combination with an opioid agonist/antagonist for sedation in Weddell seal ...

Why Does Arctic Sea Ice Respond More Evidently than Antarctic Sea Ice to Climate Change?

open access: yesOcean-Land-Atmosphere Research, 2023
The current climate change episode has impacted sea ice in the 2 polar regions differently. In the Arctic, remarkable sea ice extent and thickness declines have been observed with a stunning depletion rate of old ice.

The Amundsen Sea and the Antarctic Ice Sheet [PDF]

open access: yesOceanography, 2012
A few decades ago, Antarctic ice sheets were expected to grow as the atmosphere warmed and increasing poleward moisture transport added snowfall to regions that would remain below freezing year-round. Concerns about their sensitivity to climate change were centered on air temperature and on glacially paced ice dynamics.

Antarctica's vegetation in a changing climate

open access: yesWIREs Climate Change, Volume 14, Issue 1, January/February 2023., 2023
Antarctica's unique terrestrial ecosystems are changing with significant impact on the local vegetation. Change is manifold and includes alterations in abiotic and biotic interactions. How the vegetation will respond is still unclear. Abstract Antarctica plays a central role in regulating global climatic and oceanographic patterns and is an integral ...

Robust Arctic warming caused by projected Antarctic sea ice loss

open access: yesEnvironmental Research Letters, 2020
Over the coming century, both Arctic and Antarctic sea ice cover are projected to substantially decline. While many studies have documented the potential impacts of projected Arctic sea ice loss on the climate of the mid-latitudes and the tropics, little
