Abstract

Our ignorance of what happens at the bed of a glacier is the outstanding problem in glacier flow, and serious drilling efforts are necessary for its solution. Some of the problems encountered in a small-scale drilling project to make observations at the bed of a glacier are discussed. These include the problems of thermal and cable-tool drilling and bailing in dirty, actively-deforming temperate ice using back-packable equipment, the problems of borehole photography and water turbidity, and the possible effect of the borehole on the conditions observed.
