New and improved determinations of velocity of ice streams B and C, West Antarctica
This is the publisher's version, copyright by the International Glaciological Society. Measurements of velocity have been made on and next to Ice Streams B and C, West Antarctica. The results are more precise than previous work and constitute a 93% increase in the number of values. These veloci...
