Laboratory And Field Scale Fracture Of Sea Ice.
This report contains details of laboratory and field scale studies carried out to study fracture of sea ice. The field scale studies were carried out in six field trips on in-situ arctic sea ice. Lab scale studies were carried out on the samples obtained from cores taken from the sea ice during the...
