Thwaites Glacier grounding lines for 2014 and 2019/20 from height above flotation

This data set includes two grounding-line products of Thwaites Glacier and a series of offshore pinning points for 2014 and 2019/20. The grounding lines where delineated manually from height above flotation calculations using the bathymetry model from Jordan et al. (2020), the REMA digital surface e...

Description
Summary:This data set includes two grounding-line products of Thwaites Glacier and a series of offshore pinning points for 2014 and 2019/20. The grounding lines where delineated manually from height above flotation calculations using the bathymetry model from Jordan et al. (2020), the REMA digital surface elevation model (Howat et al., 2019) for the 2014 product and ICESat-2 surface altimetry data (Smith et al., 2019) for the 2019/20 product. More details about the processing, corrections and uncertainties can be found in our publication. We would appreciate if users who think the grounding-line products are useful for your own research would cite our manuscript.
