The International Polar Year 2007–2008 (IPY) was an intensive, internationally coordinated … scientific research campaign in the Arctic and … the Antarctic sponsored by the International … Council for Science (ICSU) and the World … Meteorological Organization (WMO). In two action-packed years…
Responses by marine top predators to environmental variability … have previously been almost impossible to observe directly. By … using animal-mounted instruments simultaneously recording … movements, diving behavior, and in situ oceanographic properties…
Russian and Australian primary sources were examined in an attempt to reconstruct the voyage of the … first composite Soviet Antarctic expedition to Antarctica and from thence to Leningrad [St Petersburg].
Previous studies of Antarctic mosses … employing RAPDs have reported extraordinarily … high levels of genetic variation, even within a single … clump of moss. This is unexpected given their … extreme isolation in Antarctica and lack of sexual … reproduction. We offer an alternative explanation:
We do not yet understand why fuel spills can cause greater … damage in polar soils than in temperate soils. The role of water … in the freezing environment may partly be responsible for … why polar soils are more sensitive to pollution.
We review aspects of climate change likely to impact upon the Collembola and mites (microarthropods) of Victoria Land and the Queen Maud Mountains (VLQMM) in the Ross Sea Region of Antarctica. Five important aspects of biological and biological…
A Rayleigh-Raman lidar has been operating at Australia's Davis Station in Antarctica since early 2001. The lidar is part of a suite of instruments making measurements of various processes from the lower atmosphere to the edge of space.
Over the past few years, co-located radar and lidar measurements have been made of ice aerosol layers in the summer mesospause region (80-95 km height) above Australia's Davis station in Antarctica.
Decadal variations of the quasi-stationary wave amplitude and zonal structure are analyzed using the TOMS data. Seasonal dependence of total ozone content (TOC) is considered.
Anthropogenic CO2 added to the atmosphere during and since the industrial revolution is entering the global ocean. Addition of extra (anthropogenic) CO2 to the ocean changes the carbonate chemistry and the pH of the surface ocean…
Laboratory experiments suggest that decreased ocean carbonate-ion concentrations due to anthropogenic CO2 will result in reduced calcification rates in marine calcareous organisms.
This review of late-Holocene palaeoclimatology represents the results from a PAGES/CLIVAR … Intersection Panel meeting that took place in June 2006. The review is in three parts: the principal high-resolution … proxy disciplines (trees, corals, ice cores and documentary evidence)…
Macquarie Island, a small subantarctic island, is home to rockhopper, royal and king penguins, which are often infested with the globally distributed seabird tick, Ixodes uriae. A flavivirus, an orbivirus, a phlebovirus, and a nairovirus were isolated from these ticks and partial sequences obtained.
The polar upper atmosphere is receiving increasing interest as a natural laboratory to investigate processes and phenomena under extreme conditions, and to detect atmospheric change. During summer, temperatures in the high-latitude mesopause region (80–95 km altitude)…
We used a Rayleigh lidar located at Davis station, East Antarctica, to compare Polar … Mesospheric Cloud (PMC) and stratospheric gravity wave (GW) strengths in the … austral summer 2005–2006.
[1] Using Rayleigh lidar and Mesosphere-Stratosphere- … Troposphere radar at Davis Antarctica (68.6S) during the … 2005–2006 austral summer, we obtained the first Southern … Hemisphere common-volume measurements of Polar … Mesospheric Clouds (PMC) and Polar Mesosphere … Summer Echoes (PMSE).
