Readme file for the AAD 4528 dataset on the Wilkins and Voykeykov calving events in 2007--2008 (paper pending) Uploaded 01/02/2024 CL, RC and Voyeykov daily transects folders contain the daily ice cover for each shelf face with the data sorted as: Date_List,pack ice length (km), annual fast ice length (km), per annual fast ice length (km), sea ice length (km). Data was calculated with a shelf latitude mean + 10 degree latitude boundary and a shelf longitude mean +7, or -12 for the east/west boundary. Pack ice length was calculated using the ASMR2 ASI sea ice concentration dataset and fast ice was calculated via the outputs from Fraser et al., 2012 landfast ice dataset. Strain outputs folder contains both the strain calculated off the ice cover timeseries and the strain using a climatological average for ice cover. Each file contains Date_List,LowIce_Strain_Shelf_timeseries,w10d_strain_sum,w30d_strain_sum,w60d_strain_sum,w90d_strain_sum,w120d_strain_sum as its' file headers, with w##d indicating how many days there was a weighted flexural window applied to each timeseries, and the LowIce_Strain_Shelf_timeseries being the daily outputs. Wave statistics are present in ##_corridor_data.txt which provides the daily maximum from each idealised corridor output and ##_icelengths.txt is a summary file for average ice lengths. Fast_Ice_Composites are a combination of Fraser et al., 2012 landfast ice dataset and ASMR_2 ASI dataset used to calculate ice cover. Flags are 0 - open ocean, 1 - ice sheet, 2 - islands, 3 - ice shelf, 4 - pack ice, 5 - annual fast ice, 6 - perennial fast ice, 7 - ice shelf edge. Figure_outputs is the planned figures for this paper.
