The International Association of Meteorology and Atmospheric Sciences (IAMAS), the International Association for the Physical Sciences of the Oceans (IAPSO), and the International Association for the Cryospheric Sciences (IACS) invite submissions to session J01, "Observations of High Latitude Climate Change," to be held at the MOCA Joint Assembly, 19-24 July 2009 in Montreal, Quebec, Canada ( The abstract submission deadline is Friday, 23 January 2009.

Session conveners seek abstract submissions for relevant papers that bring together observational descriptions of the high latitude regionsin the atmosphere, ocean and cryosphere from 200 years ago to the present. Topics from both polar regions as well as from in situ and space based observing platforms are the basis for this symposium. New observations collected via recent efforts, including the International
Polar Year (IPY), International Trans-Antarctic Scientific Expedition (ITASE), and other ongoing long-term observational and paleo-climate efforts related to climate change at the poles, are solicited. In
addition, presentations dealing with observational and data assimilation methods are welcome.

Sample topic areas include ice core observations, mass balance investigations (surface, airborne, or satellite based), satellite observations (e.g., altimetry, clouds, icebergs, etc.), ocean monitoring
studies (e.g., ARGO, AON, etc.), polar surface observing networks (e.g., Automatic Weather Stations, ground-based GPS, etc.), and data syntheses from reanalysis.

Abstracts are due Friday, 23 January 2009. For further information, including directions for submission of abstracts, please go to:
