Fast ice makes up about 10 % by area (or 14 - 20 % by volume) of the total … Antarctic pack. Its growth is largely determined by thermodynamics processes, which makes it a valuable tool to monitor changes in the polar climate system. Time series of fast-ice properties…
This reference document provides information on physical and biological data layers that … have been collated in advance of the 2007 CCAMLR Workshop on Bioregionalisation. This is … not an exhaustive list, as additional data may be made available by participants during the … workshop itself.
Ozone climatologies are presented for a number of locations in the Australian region, making use of … both total ozone and ozone profile data, as measured by the Bureau of Meteorology’s Dobson and … ozonesonde networks. For mid-latitude sites (Melbourne and Macquarie Island)…
Understanding and characterising the variability of ozone in the lower atmosphere is a key aspect of … regional and global climate assessment. Tropospheric ozone influences climate by absorbing outgoing … longwave terrestrial radiation, thereby acting as a greenhouse gas…
In September 2007, a multi-disciplinary sea-ice voyage, jointly organised by the Australian Government Antarctic Division and the Antarctic Climate and Ecosystems Cooperative Research Centre, sailed from Hobart. The focus of the Sea Ice Physics and Ecosystems Experiment (SIPEX)…
The event that occurred approximately 8200 years ago is the largest excursion in climate since the beginning of the Holocene. In this event we observe the climatic response to a perturbation which provides a probe with which to investigate the stability of interglacial climate.
Antarctic fast ice is of key climatic and ecological importance, yet its distribution and variability are poorly understood (compared to pack ice). In this joint Australian-French study…
Hot water drilling of the Amery Ice Shelf conducted as a component of the AMISOR (Amery Ice Shelf Ocean Research) project to enable access the underlying ocean cavity has allowed limited retrieval of ice cores using a hot water coring barrel.
Information of sea-ice drift is crucial to understand the East Antarctic climate system, and knowledge of sea-ice dynamics is needed to fully explore the effects of cryospheric changes on the ecosystems within the Antarctic pack-ice zone. Satellite-derived sea-ice data cover the Southern Ocean.
Quantifying the contribution of solar variability to past and present climate change has been an important and controversial aspect of climate research. 10Be records from polar ice have played a key role in extending solar activity reconstructions beyond the period of direct observations of the sun.
Abstract: Two identical calibration neutron monitors were completed in September 2002. They are … designed to provide an intercalibration between the ¡Ö 50 neutron monitors around the world, so that … rigidity spectra can be calculated from them.
We investigated the unidirectional fractional density gradient in GSE-z (GzU) of Galactic Cosmic Ray (GCR) by using the data obtained by the Muon detector network. The analysis period is from 1994 to 2005. We found that the yearly averaged GzU show temporal variations.
First results of the Muon Spaceweather Telescope for Anisotropies at Greifswald (MuSTAnG) that is dedicated to spaceweather forecasting are reported.
We have developed a method for determining ICME (Interplanetary coronal mass ejection) geometry from galactic cosmic ray data recorded by the ground-based muon detector network. The … cosmic ray density depression inside the ICME, which is the cause of a Forbush decrease…
The galactic cosmic ray (GCR) intensity often shows a dramatic variation responding to the arrival of interplanetary disturbances at the Earth. Aiming to observe such a variation with muon detectors…
This paper presents the average sidereal anisotropy (SA) of sub-TeV galactic cosmic ray intensity observed with a two-hemisphere network (THN) of underground muon detectors over 15 years. The average SA confirms the conclusions derived from the initial 5-year data by THN [1][2]…
