Ice Core Evidence for Antarctic Sea Ice Decline Since the 1950s
TLDR
A significant correlation is reported between methanesulphonic acid concentrations from a Law Dome ice core and 22 years of satellite-derived sea ice extent (SIE) for the 80°E to 140°E sector and suggests that there has been a 20% decline in SIE since about 1950.Abstract:
The instrumental record of Antarctic sea ice in recent decades does not reveal a clear signature of warming despite observational evidence from coastal Antarctica. Here we report a significant correlation ( Pread more

Long-term decline in krill stock and increase in salps within the Southern Ocean.
TL;DR: This database shows that the productive southwest Atlantic sector contains >50% of Southern Ocean krill stocks, but here their density has declined since the 1970s, and salps appear to have increased in the southern part of their range.

TL;DR: It is suggested that cell size and elemental stoichiometry are promising ecophysiological traits for modelling and tracking changes in phytoplankton community structure in response to climate change.

TL;DR: A review of late-Holocene palaeoclimaoclimatology represents the results from a PAGES/CLIVAR Intersection Panel meeting that took place in June 2006 as mentioned in this paper, emphasizing current issues in their use for climate reconstruction; various approaches that have been adopted to combine multiple climate proxy records to provide estimates of past annual-to-decadal timescale Northern Hemisphere surface temperatures and other climate variables, such as large-scale circulation indices; and the forcing histories used in climate model simulations of the past millennium.

TL;DR: The Southern Hemisphere climate system varies on timescales from orbital, through millennial to sub-annual, and is closely coupled to other parts of the global climate system as discussed by the authors.

An Antarctic circumpolar wave in surface pressure, wind, temperature and sea-ice extent
Warren B. White,Ray G. Peterson +1 more
TL;DR: The Southern Ocean is the only oceanic domain encircling the globe and contains the strong eastward flow of the Antarctic Circumpolar Current, and is the unifying link for exchanges of water masses at all depths between the world's major ocean basins as discussed by the authors.

Emperor penguins and climate change
TL;DR: The results indicate strong and contrasting effects of large-scale oceanographic processes and sea-ice extent on the demography of emperor penguins, and their potential high susceptibility to climate change.

Freshening of the Ross Sea During the Late 20th Century
TL;DR: Ocean measurements in the Ross Sea over the past four decades reveal marked decreases in shelf water salinity and the surface salinity within the Ross Gyre, which appears to have resulted from a combination of factors, including increased precipitation, reduced sea ice production, and increased melting of the West Antarctic Ice Sheet.

Observed Hemispheric Asymmetry in Global Sea Ice Changes
TL;DR: From November 1978 through December 1996, the areal extent of sea ice decreased by 2.9 ± 0.4 percent per decade in the Arctic and increased by 1.3 − 0.2 percent in the Antarctic as mentioned in this paper.

Antarctic sea ice extent variability and its global connectivity
TL;DR: In this article, the temporal cross correlations between detrended Antarctic sea ice edge (SIE) anomaly and various climate indices are calculated, showing that up to 34% of the variance in SIE* is linearly related to ENSO.
