DOI: 10.1017/aog.2017.1
Abstract: ABSTRACT Calving is a complex process subject to several cooperating atmospheric, oceanographic and glaciological forcings that vary in space and time, and whose relative effects are challenging to separate. Statistical ‘Systems Analysis’ is commonly used… read more here.
