Interhemispheric dynamical coupling to the southern Mesosphere and Lower Thermosphere. 38th COSPAR Scientific Assembly, Bremen, Germany 18-25 July 2010, 2010 (Ref: 14286)
Category 3: Verbal presentation

The 15-year set of radar observations of Mesosphere and Lower Thermosphere (MLT) winds obtained from Davis station in Antarctica (69S, 78E) provide an opportunity for studies of interhemispheric coupling. Observations and modelling described by Becker and Fritts [2006]…

Cosmic Ray Flux at the Recent Solar Minimum. Session 3F, 19th Australian Institute of Physics Congress, 5-9 December 2010 Extended Abstracts CD., 2010 (Ref: 14281)
Category 3: Abstract

After an unusually (for recent solar cycles) long absence, sunspots of solar cycle 24 started to appear late in 2009. Cosmic ray activity monitored at Earth has an inverse … relationship with the sunspot cycle, being maximum at solar … minimum.

Bullets from the Sun: A Review of Relativistic Solar Cosmic Rays. Session 3F, 19th Australian Institute of Physics Congress, 5-9 December 2010 Extended Abstracts CD., 2010 (Ref: 14280)
Authors:
Category 3: Abstract

Cosmic rays generally come from beyond the solar system but rarely they can come from the Sun. This review discusses the solar source, propagation to Earth and impact of highly relativistic solar protons.

New constraints on the structure and dynamics of the East Antarctic Ice Sheet from the joint IPY/Ice Bridge ICECAP aerogeophysical project. Abstract C22B-05 presented at 2010 Fall Meeting, AGU, San Francisco, Calif., 13-17 Dec., 2010 (Ref: 14275)
Category 3: Verbal presentation

Ice within marine basins of East Antarctica, and their outlets, represent the ultimate limit on sea level change. The region of East Antarctica between the Ross Sea and Wilkes Land hosts a number of major basin, but has been poorly understood. Long range aerogeophysics from US…

The Medieval Climate Anomaly - A View From Down Under. Abstract PP34B-06 presented at 2010 Fall Meeting, AGU, San Francisco, Calif., 13-17 Dec., 2010 (Ref: 14274)
Category 3: Verbal presentation

Knowledge of environmental variability and change during the … Medieval Climate Anomaly (MCA ; ~800 to 1300 - 1400 AD) in the Southern Hemisphere has been characterized by a La Nina-like mean climate state in the Pacific Basin…

Spatial variability of black carbon deposition to Antarctica over the 20th Century. West Antarctic Ice Sheet (WAIS) Divide Workshop, La Jolla, USA, September 2010, 2010 (Ref: 14261)
Category 3: Verbal presentation

Black carbon (BC), the primary light-absorbing aerosol in the atmosphere, is emitted by the incomplete combustion of biomass and fossil fuels affecting the radiative balance of the atmosphere. As a contributor to climate change, BC may rival greenhouse gases such as methane.

New constraints on north-south climate coupling and the CO2/temperature relation during the last deglaciation from polar ice cores. First Australian Earth System Outlook Conference, Australian Academy of Science, Canberra. December 9-10., 2010 (Ref: 14276)
Category 3: Conference paper

Ice core records from Antarctic and Greenland have revealed that the last deglaciation (ca. 19,000 to 11,000 years before present) was accompanied by a ca. 80 ppmv increase in atmospheric CO2 and a sequence of large, hemispheric climate variations.

10Be in Antarctic ice: Solar activity and climate signals observed and GCM-modelled at high resolution. Astronomical Society of Australia Annual Science Meeting 2010, Hobart, 5-8 July, 2010 (Ref: 14166)
Category 3: Poster

Changes in solar activity modulate the galactic cosmic ray flux, and in turn, the production rate of cosmogenic 10Be in the Earth’s atmosphere. The best archives of past changes in 10Be production rate are polar ice cores.

Abrupt Changes in Microparticle Concentration and Grainsize in Snow Accumulation During the Last Deglaciation on Law Dome, East Antarctica. Australia New Zealand Climate Forum, Hobart, September 2010, 2010 (Ref: 14252)
Category 3: Conference paper

The Dome Summit South ice core from Law Dome, East Antarctica is 1200 m long and reveals an unusually high accumulation rate for Late Holocene precipitation (640 kg m2/a), dating to 90,000 years before present (BP) at its base.

Ice Core Records of the Last Deglaciation: North-South Climate and Atmospheric CO2. Australia New Zealand Climate Forum, Hobart, September 2010, 2010 (Ref: 14251)
Category 3: Conference paper

Ice core records from Antarctic and Greenland have revealed that the last deglaciation (ca. 19, 000 to 11, 000 years before present) was accompanied by an 80 ppmv increase in atmospheric CO2 and a sequence of large, hemispheric climate variations.

Correspondence on Geisz et al. Melting Glacier: A Probable Source of DDT to the Antarctic Marine Ecosystem Environmental Science and Technology, 2009 (Ref: 13828)
Category 1: Peer-reviewed literature

Geisz et al. report an unexpected consequence of climate … change, implicating glacier meltwater as a source for DDT … in coastal Antarctic seas (1). Hypothetically, glaciers may … act as secondary sources for DDT and there may be a link … to climate change. However, their data are sparse, variable…
