ANTARCTIC CLIMATE & ECOSYSTEMS COOPERATIVE RESEARCH CENTRE Media Release embargoed until 10:00 am 17 April 2008 Polar Year expedition returns with evidence of ocean change The Aurora Australis returns to Hobart this morning, after completing a major oceanographic expedition across the Southern Ocean. The Climate of Antarctica and the Southern Ocean (CASO) voyage obtained the most accurate and complete measurements of the ocean currents between Australia and Antarctica yet taken, providing important information that will improve models used to predict climate change. “We have collected a remarkable data set of observations from the Southern Ocean, covering a wide range of physical, chemical and bio...

Ice cores are essential for climate research, because they represent the only archive which allows direct measurements of atmospheric composition and greenhouse gas concentrations in the past. Using novel isotopic studies, scientists from the European Project for Ice Coring In Antarctica (EPICA) w...

History of Winter-HOW introduction. The History of Winter (HOW) program is comprised of a one week professional development/"teacher as scientist" cryosphere science training camp, held annually during mid February in Lake Placid, New York. Each year the NASA Goddard HOW program selects a diverse group of teachers from around the country to participate in a comprehensive study of winter in the Northern Hemisphere. The winter landscape is used as a "teacher" to better understand snow and ice processes and the impact of weather and climate at the micro and mesoscale. Snow in the air and on the ground, ice on Earth and in the Solar System, its crystal structure and axial orientation, and the ecosystem consequences of snow and ice constitute the week-long co...
