, a member of several USARP expeditions to Antarctica; leader of the University of Minnesota Ellsworth Mountains Party, 1963-1964. Rutford served as Director of the Division of Polar Programs, National Science Foundation, 1975-1977. The ice stream is situated in a deep trough which is a tectonic feature between the Ellsworth Mountains and the Fletcher Promontory. Because of this the ice stream position may have been stable for millions of years. The bed of the ice stream reaches below sea level. Therefore, between the bed of the ice stream and the height of the Ellsworth Mountains there is a vertical relief of over a distance of only . At the upper (inland) end of the ice stream the ice thickness reaches falling to around in the trough. Flow speed reaches a maximum of around per year about inland from where the ice stream meets the Ronne Ice Shelf and starts to float on the sea. The speed of the Rutford ice stream varies by as much as 20% every two weeks, in response to variations in the

tides Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can ...
