Hi Jeff, I agree with you that GLIMS acquisitions should be reprioritized to areas of currently poor coverage, but this shouldn't be at the expense of losing all coverage in the northern high latitudes (as your suggestion for a moratorium there seems to suggest). ASTER provides the only low cost, high resolution satellite imagery source in the high arctic and is therefore invaluable in monitoring recent changes. Examples include the recent rapid retreat of the terminus of Jakobshavn Isbrae, and the loss of ice shelves along northern Ellesmere Island. You also need to remember that 2007-8 is the International Polar Year, and that if anything we should be trying to increase monitoring then. My suggestion would be to reduce northern high latitude acquisitions to a 'background' level, but not to get rid of them altogether. If this is too general, then perhaps you should put out a call for specific acquisition requests from the groups that will be working there to get an idea of where acquisitions should be focused.
