Click on an X to get the file from each source.

Each summary file has data on up to three different variables which are listed in the last column.

 

Metadata:
Platform_metatdata, This file has a line for each mooring, campaign, or station with the time and position ranges for that platform and the number of point measurements and aggregate samples.


Data formats:

Draft, Thickness, or Freeboard Summaries
Each file begins with one header line identifying the variables. The variables are listed in the table below. The header and data formats are
hdr_fmt = '( 2a12, a10, 5a7, 6a8, a7, a10, 4(4a10) ) '
data_fmt = '( 2a12, i10, i7,3f7.1,i7, 6f8.2, i7, i10, 4(4f10.2) )'

Ice Thickness Distribution Files
Each file begins with one header line identifying the variables. The variables are listed in the table below with typical values of the number of bins, bin width, and first bin in brackets. The header and data formats are
hdr_fmt = '( 2a12, a10, 5a7, 6a8, a7, a10, a6, 8a7)'
data_fmt = '( 2a12, i10, i7,3f7.1,i7, 6f8.2, i7, i10, i6,2f7.2, 300f7.4 )'
