Winter sea ice growth processes:
the impact of winter growth on sea ice thickness
The thickness and growth of coastal sea ice during winter is a key unknown when considering polar influences on climate. Much of the coastline of Antarctica is ice shelf. Melting and/or freezing at the base of an ice shelf influences the heat content and salinity of the water in contact with it. In turn this strongly controls near-surface oceanography.
During the southern winter of 2009 (February-October) there will be an extensive programme of sea ice and ocean measurements in McMurdo Sound, Antarctica. You can read the blog on the IPY site.
The team at Scott Base will also link to the IPY IGLO live event. There are two institutions that will be participating in the interactive portion of the event (Chicago Museum of Science and Industry and the National Museum of Mexico). Students at these locations will be able to ask questions about the work going on at Scott Base via the video conferencing system. Two other institutions (San Francisco Exploratorium and the Maryland Science Centre) will be tuning in via a webcast but will also be able to ask questions via email.
