Abstract
We assess ice loss and velocity changes between 1985 and 2014 of three tidewater and five-land terminating glaciers in Godthåbsfjord (Nuup Kangerlua), Greenland. We present comprehensive analyses of glacier thinning, runoff, surface mass balance, ocean conditions, submarine melting, bed topography, ice mélange and conclude that the 2010–14 NS retreat was triggered by a combination of factors but primarily by an increase in submarine melting.

Updated status to done after final check.

Version 3

Wed, 27 Sep 2023 14:10:47 +0200

Data were cleaned of outliers, metadata was corrected and added, status set to finalising pending final check in grid.

Version 2

Mon, 11 Sep 2023 14:07:28 +0200

Data were added to the grid and weight and gridding resolution were assigned.

Version 1

Fri, 03 Mar 2023 15:33:07 +0100

Data were unzipped from dataset #1255, split into several datasets, each converted from matlab to xyz and transformed from EPSG 3413 to 3996 using pre-processing script
Knut and Alice Wallenberg Foundation (KAW) and Swedish Research Council (VR) financed the Oden multibeam system and the installation was financed by the Swedish Maritime Administration. The Oden expeditions were organized by the Swedish Polar Research Secretariat. This Mapping Repository is a part of the Bert Bolin Centre for Climate Research data archive.
