Ice Core Records As Sea Ice Proxies: an Evaluation from the Weddell Sea Region of Antarctica Nerilie J
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 112, D15101, doi:10.1029/2006JD008139, 2007 Click Here for Full Article 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. -

Byers Peninsula, Livingston Island, South Shetland Islands 1
From Measure 1 (2002) Management Plan for Antarctic Specially Protected Area No. 126 BYERS PENINSULA, LIVINGSTON ISLAND, SOUTH SHETLAND ISLANDS 1. Description of values to be protected Byers Peninsula (latitude 62°34’35" S, longitude 61°13’07" W, 60.6 km2), Livingston Island, South Shetland Islands, was originally designated as Specially Protected Area (SPA) No. 10 through Recommendation IV-10 in 1966. This area included the ice-free ground west of the western margin of the permanent ice sheet on Livingston Island, below Rotch Dome, as well as Window Island about 500 m off the northwest coast and five small ice-free areas on the south coast immediately to the east of Byers Peninsula. Values protected under the original designation included the diversity of plant and animal life, many invertebrates, a substantial population of southern elephant seals (Mirounga leonina), small colonies of Antarctic fur seals (Arctocephalus gazella), and the outstanding scientific interest associated with such a large variety of plants and animals within a relatively small area. Designation as an SPA was terminated through Recommendation VIII-2 and redesignation as a Site of Special Scientific Interest (SSSI) was made through Recommendation VIII-4 (1975, SSSI No. 6). The new designation as an SSSI more specifically sought to protect three smaller ice-free sites on the peninsula of Jurassic and Cretaceous sedimentary and fossiliferous strata, considered of outstanding scientific value for study of the former link between Antarctica and other southern continents. Following a proposal by Chile and the United Kingdom, the SSSI was subsequently extended through Recommendation XVI-5 (1991) to include boundaries similar to those of the original SPA: i.e. -
