Abstract

Surface ice-flow velocities measured at stakes on Rutford Ice Stream, West Antarctica, covering a period of ∼25 years are analysed for evidence of temporal variations in flow. No indications of significant long-term changes in flow are found. Earlier observations have shown significant tidally related variations in flow speed. We conclude that temporal variability on Rutford Ice Stream, West Antarctica, appears limited to tidal periods of days and weeks, and weaker interannual variation, possibly related to long-period tides or seasonal effects, while long-term (decadal) changes in flow speed are either absent or smaller than ∼0.1 % a-1.
