This dataset provides the data produced as part of the work published in: Leeson, A. A., Foster, E., Rice, A., Gourmelen, N. and van Wessem, J. M.. 2019. 'Evolution of supraglacial lakes on the Larsen B ice shelf in the decades before it collapsed' Geophysical Research Letters. It includes 1) shapefiles of supraglacial lakes mapped in both optical (Landsat) and SAR (ERS) satellite imagery, 2) rasters of lake depth, derived from Landsat TM and ETM+ images acquired in 1988 and 2000 and 3) shapefiles of the study area considered in the paper. Funding was provided by ERPSRC grant EP/R01860X/1. : Under embargo until publication. : Horizontal resolution is nominally 30 m, since this is the resolution of the satellite imagery from which the data is derived. See Leeson et al., 2019 for details. : Under embargo until publication.
