Data processing notes

Data points in LeSchack 1980 reflect 50-km summaries of ice draft, standard deviation of ice draft and amount of open water. To make consistent with other data sets in the CDR, the reported ice draft iin the paper is normalized to include open water fraction by multiplying by ice concentraction. Data tables in include reported ice concentration as the first variable (Note that this differs from other Submarine ULS data)LeShack.1980_from_Terry_Tucker
