title: Topographic and geologic controls on the Northeast Greenland Ice Stream
abstract: Abstract The Northeast Greenland Ice Stream (NEGIS) is an elongated feature extending ∼600 km into the interior of the Greenland Ice Sheet. Here, we investigate detailed subglacial topography along the length of the NEGIS to ascertain the characteristics of the ice stream bed. We use topographic analysis (hypsometry, spatial roughness and valley morphometry) to describe and demarcate three geomorphologically distinct regions. The upstream region, near the NEGIS onset, exhibits low roughness and
