Terrestrial ecosystems in Arctic and Antarctic: effects of UV light, liquefying ice, and ascending temperatures (TARANTELLA)
Predicted changes in climate and ozone concentrations in the Polar Regions make it critically important to understand how changes in key environmental factors influence polar terrestrial ecosystems via the modification of their individual but interconnected components.
Observational and experimental research on the effect of climate change and ozone depletion is affiliated to international research programmes including the EBA, Evolution and Biodiversity in the Antarctic project, SCAR in the Antarctic, and in the Arctic to ITEX, International Tundra Experiment as well as IGBP-GCTE.
TARANTELLA aims to coordinate these studies by focusing on the experimental approach, in both the Arctic, in collaboration with ITEX, and in the Antarctic.
A common methodology is used, the so-called Open-Top Chambers (OTC) or small greenhouses for temperature manipulations; for UV-B field research, UV-B supplementation (lamps) and/or UV-B exclusion (foils), are used to experimentally establish varied UV-B levels.
IceCube is a neutrino observatory for astrophysics to be installed at the South Pole over seven austral summers ending in 2011. IceCube will look for extremely high-energy neutrinos coming from the northern sky whose sources are active galactic nuclei, supernova remnents, gamma-ray bursts, and active supernovae. The IceCube In-Ice detector will consist of a minimum of 4800 optical modules deployed on 80 vertical strings buried 1450 to 2450 meters under the surface of the ice, and an IceTop surface air-shower detector array comprised of a minimum of 320 optical modules. By early 2008, one half of the detector, 40 strings with 2400 optical modules, was collecting, storing and analyzing data. Weekly updates during the austral season, November-January, are posted here.
IceCube is an international project sponsored and conducted by the United States and several non-U.S. countries. The United States National Science Foundation supplies funds for the design, development, fabrication, procurement, testing, drilling and operations of the project at the South Pole.
