Southern Hemisphere climate reconstructions are limited by quantity and spatial coverage of well resolved paleoclimaterecords from the last 2000 years. This was the motivation to drill an ice core at a new site in East Antarctica…
Sea ice plays an important role in ocean–atmosphere heat exchange, global albedo and the marine ecosystem. Knowledge of variation in sea-ice extent is essential in order to understand past climates, and to model possible future climate scenarios.
Lead (Pb) isotopic compositions and concentrations, and barium (Ba) and indium (In) concentrations have been determined at monthly resolution in five Law Dome (coastal Eastern Antarctica) ice core sections dated from ~1757 AD to ~1898 AD. [`]…
Continuous high-resolution oxygen isotope measurements (¥ä18Oice) have been made along the … entire length of the Dome Summit South (DSS) ice core from Law Dome (LD), Antarctica, spanning the past 90ky.
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.
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.
The southwest corner of Western Australia has been subject to a serious drought in recent decades. A range of factors, such … as natural variability and changes in land use, ocean temperatures and atmospheric circulation, have been implicated in this … drought…
Ice cores from coastal East Antarctica provide highly resolved records that capture seasonal variations … in a wide range of climate proxies.
During the transition from the last glacial maximum to the present warm interglacial a sequence of large, hemispheric, climate changes took place: the Bølling‐Allerød and Younger … Dryas in the north and the Antarctic Cold Reversal in the south.
Physiological measurements of both stress and … sex hormones are often used to estimate the consequences … of natural or human-induced change in ecological studies of … various animals. DiVerent methods of hormone measurement … exist…
Recent model calculations have attempted to quantify the contribution of … major energetic solar cosmic ray (SCR) events to 10Be production.1,2 In this … study we compare modeled 10Be production by SCR events to measured … 10Be concentrations in a Law Dome snow pit record.
Quantifying the contribution of solar variability to past and present climate change has been … an important and controversial aspect of climate research.
This work contributes to the understanding of variation in methanesulphonic (MSA) concentration in an ice core … drilled during the 1996-97 Antarctic Campaign at the coastal plateau site of Talos Dome (East Antarctica)…
Firn core methanesulphonic acid (MSA) stratigraphy from Talos Dome (East … Antarctica) was compared with anomalies of the satellite-measured sea ice … extent (1973–1995) in the Ross Sea and Wilkes Land oceanic sector. In spite … of the sparseness of sea ice data…
Modelled 10Be production by solar cosmic ray (SCR) events is compared with measured 10Be concentrations … in a Law Dome snow pit record. The snow pit record spans 2.7 years, providing a quasi-monthly 10Be … sampling resolution which overlaps with the SCR events of 29 Oct 2003 and 20 Jan 2005.
Law Dome, in coastal East Antarctica, is a relatively low-latitude site (6646S) with a strong maritime … climate, dominated by cyclonic precipitation which produces high snow accumulation rates and very … well-resolved ice core records.
Ice cores from Law Dome, in coastal East Antarctica, provide climate records that have strong connections to … the Southern Ocean and mid-latitude climate in the … Australian region. The overall climate history available from … Law Dome extends back for tens of millennia…
