Radar Interferometry, ice-penetrating radar profiles, and an elevation model are used to determine the catchment area, rates of ice discharge, and approximate states of balance for three large outlet glaciers in northeast Greenland. |

Joughin, I.; Tulaczyk, Slawek; Fahnestock, M.; Kwok, R., 1996, "(abstract) A Mini-Surge on the Ryder Glacier, Greenland", https://hdl.handle.net/2014/26514, SAn Francisco, CA, JPL Open Repository
We have detected a dramatic short-term speedup of the Ryder Glacier, Greenland, using satellite radar interferometry. The accelerated flow represents a substantial, though short-lived, change in the ice discharge from the basin. We use the term |

Joughin, I.; Kwok, R.; Fahnestock, M., 1996, "(abstract) Three Dimensional Ice-Flow Velocity Estimation Using Satellite Radar Interferometry", https://hdl.handle.net/2014/26513, San Francisco, CA, JPL Open Repository
An understanding of the flow dynamics of an ice sheet's outlet glaciers and ice streams requires knowledge of their flow velocity and strain rates (i.e., velocity gradients). Prior to the recent advent of satellite radar interferometry, it was not possible to measure detailed ice... |

A dramatic short term speed up of the Ryder glacier has been detected using satellite radar interferometry. The accelerated flow represents a substantial, though short-lived, change in the ice discharge from this basin. We believe that meltwater was involved in this event, either... |

Satellite radar interferometry provides an importatn new tool for determining ice-flow velocity. Interferometric measurements made from a single track direction are sensitive only to a single component of the three-dimensional velocity vector. Observations from along thre differe... |
