Ice Core Records As Sea Ice Proxies: an Evaluation from the Weddell Sea Region of Antarctica Nerilie J

Abram,1 Robert Mulvaney,1 Eric W. Wolff,1 and Manfred Mudelsee2,3 Received 12 October 2006; revised 2 May 2007; accepted 5 June 2007; published 3 August 2007. [1] Ice core records of methanesulfonic acid (MSA) from three sites around the Weddell Sea are investigated for their potential as sea ice proxies. It is found that the amount of MSA reaching the ice core sites decreases following years of increased winter sea ice in the Weddell Sea; opposite to the expected relationship if MSA is to be used as a sea ice proxy. It is also shown that this negative MSA-sea ice relationship cannot be explained by the influence that the extensive summer ice pack in the Weddell Sea has on MSA production area and transport distance. A historical record of sea ice from the northern Weddell Sea shows that the negative relationship between MSA and winter sea ice exists over interannual (7-year period) and multidecadal (20-year period) timescales. National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis data suggest that this negative relationship is most likely due to variations in the strength of cold offshore wind anomalies traveling across the Weddell Sea, which act to synergistically increase sea ice extent (SIE) while decreasing MSA delivery to the ice core sites. Hence our findings show that in some locations atmospheric transport strength, rather than sea ice conditions, is the dominant factor that determines the MSA signal preserved in near-coastal ice cores. -
Species Status Assessment Emperor Penguin (Aptenodytes Fosteri)

Photo Credit: Gary Miller, Australian Antarctic Program. Version 1.0 December 2020 U.S. Fish and Wildlife Service, Ecological Services Program Branch of Delisting and Foreign Species Falls Church, Virginia Acknowledgements: EXECUTIVE SUMMARY Penguins are flightless birds that are highly adapted for the marine environment. The emperor penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species. Emperors are near the top of the Southern Ocean’s food chain and primarily consume Antarctic silverfish, Antarctic krill, and squid. They are excellent swimmers and can dive to great depths. The average life span of emperor penguin in the wild is 15 to 20 years. Emperor penguins currently breed at 61 colonies located around Antarctica, with the largest colonies in the Ross Sea and Weddell Sea. The total population size is estimated at approximately 270,000–280,000 breeding pairs or 625,000–650,000 total birds. Emperor penguin depends upon stable fast ice throughout their 8–9 month breeding season to complete the rearing of its single chick. They are the only warm-blooded Antarctic species that breeds during the austral winter and therefore uniquely adapted to its environment. Breeding colonies mainly occur on fast ice, close to the coast or closely offshore, and amongst closely packed grounded icebergs that prevent ice breaking out during the breeding season and provide shelter from the wind. Sea ice extent in the Southern Ocean has undergone considerable inter-annual variability over the last 40 years, although with much greater inter-annual variability in the five sectors than for the Southern Ocean as a whole. -
Representations of Antarctic Exploration by Lesser Known Heroic Era Photographers
Filtering ‘ways of seeing’ through their lenses: representations of Antarctic exploration by lesser known Heroic Era photographers. Patricia Margaret Millar B.A. (1972), B.Ed.

Patricia Margaret Millar Date ii Abstract Photographers made a major contribution to the recording of the Heroic Era of Antarctic exploration. By far the best known photographers were the professionals, Herbert Ponting and Frank Hurley, hired to photograph British and Australasian expeditions. But a great number of photographs were also taken on Belgian, German, Swedish, French, Norwegian and Japanese expeditions. These were taken by amateurs, sometimes designated official photographers, often scientists recording their research. Apart from a few Pole-reaching images from the Norwegian expedition, these lesser known expedition photographers and their work seldom feature in the scholarly literature on the Heroic Era, but they, too, have their importance. They played a vital role in the growing understanding and advancement of Antarctic science; they provided visual evidence of their nation’s determination to penetrate the polar unknown; and they played a formative role in public perceptions of Antarctic geopolitics. -

Observation of Ocean Tides Below the Filchner
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 105, NO. C8, PAGES 19,615-19,630,AUGUST 15, 2000 Observation of ocean tides below the Filchher and Ronne Ice Shelves, Antarctica, using synthetic aperture radar interferometry' Comparison with tide model predictions E. Rignot,1 L. Padman,•' D. R. MacAyeal,3 and M. Schmeltz1 Abstract. Tides near and under floating glacial ice, such as ice shelvesand glacier termini in fjords, can influence heat transport into the subice cavity, mixing of the under-ice water column, and the calving and subsequentdrift of icebergs. Free- surface displacementpatterns associatedwith ocean variability below glacial ice can be observedby differencingtwo syntheticaperture radar (SAR) interferograms, each of which representsthe combination of the displacement patterns associated with the time-varying vertical motion and the time-independent lateral ice flow. We present the pattern of net free-surface displacement for the iceberg calving regions of the Ronne and Filchher Ice Shelves in the southern Weddell Sea. By comparing SAR-based displacementfields with ocean tidal models, the free-surface displacementvariability for these regions is found to be dominated by ocean tides. The inverse barometer effect, i.e., the ocean's isostatic responseto changing atmospheric pressure, also contributes to the observed vertical displacement. The principal value of using SAR interferometry in this manner lies in the very high lateral resolution(tens of meters) obtainedover the large regioncovered by each SAR image. Small features that are not well resolvedby the typical grid spacing of ocean tidal models may contribute to such processesas iceberg calving and cross-frontalventilation of the ocean cavity under the ice shelf. -
Dear Secretary Salazar: I Strongly
Dear Secretary Salazar: I strongly oppose the Bush administration's illegal and illogical regulations under Section 4(d) and Section 7 of the Endangered Species Act, which reduce protections to polar bears and create an exemption for greenhouse gas emissions. I request that you revoke these regulations immediately, within the 60-day window provided by Congress for their removal. The Endangered Species Act has a proven track record of success at reducing all threats to species, and it makes absolutely no sense, scientifically or legally, to exempt greenhouse gas emissions -- the number-one threat to the polar bear -- from this successful system. I urge you to take this critically important step in restoring scientific integrity at the Department of Interior by rescinding both of Bush's illegal regulations reducing protections to polar bears.
