The dataset consists of three shapefiles containing terminus positions of the Koge Bugt North, Koge Bugt Central, and Koge Bugt South glaciers respectively, between 2022-2023. The terminus positions were manually digitised using either Landsat-8 or Landsat-9 imagery, downloaded from the USGS Earth Explorer (https://earthexplorer.usgs.gov/). If suitable optical imagery was unavailable, MEaSUREs Sentinel-1A and Sentinel-1B synthetic aperture radar (SAR) mosaics were employed, downloaded from the National Snow and Ice Data Center (NSIDC; Joughin, 2021). The dataset comprises 71 terminus positions in total, each digitised from imagery collected between 2022-01-11 and 2023-12-08.

The dataset consists of a single shapefile containing terminus positions of Jakobshavn Isbrae, Ilulissat Icefjord, Greenland, between 2022-2023. Jakobshavn Isbrae is a fast-flowing outlet glacier situated in central west Greenland and terminates in Ilulissat Icefjord, a deep fjord basin renewed by water from Disko Bay (Gladish et al., 2015). Each polyline feature in this dataset reflects a terminus position manually digitised using synthetic aperture radar (SAR) mosaics downloaded from the National Snow and Ice Data Center (NSIDC; Joughin, 2021). The dataset comprises 31 terminus positions in total, each digitised from imagery collected between 02/01/2022 and 28/12/2022.

A dataset of ice-margin change (advance/recession) at the south-western sector of the Greenland Ice Sheet, comprising data from 3325 terrestrial, 439 lacustrine and 35 marine ice-margins respectively. The dataset also comprises measures of ice-marginal lake parameters including area and intersect (length of the lake - ice-margin interface). Measurements were made at approximately five year intervals (epochs) from 1987 to 2015. The ice sheet margin and adjacent ice-marginal lakes were delineated by applying the Normalised Difference Snow Index (NDSI) and the Normalised Difference Water Index (NDWI) respectively to Landsat TM, ETM+ and OLI scenes. Ice-margin changes were measured relative to a series of fixed reference points. The dataset was generated to facilitate comparison of changes at the disparate ice-marginal environments of the ice sheet and investigate temporal patterns of ice-margin recession. The dataset was created and processed by researchers in the School of Geography at the University of Leeds and the Institute of Integrative Biology at the University of Liverpool.
