| Summary: | Bibliography: p. 291-310. ... : The object of the research was to investigate the growth and structure of Ward Hunt and Milne Ice Shelves which have recently produced ice islands. The work involved ice core drilling and collection of snow and fiord water samples. These have been the subject of conductivity (SEC)-salinity, 180, tritium, ice density and ice texture analysis. Accorct;ng to these parameters, ten ice types have been identified (Tables 5.12A and 5.12B) and each is found in or adjacent to the ice shelves and plays a role in their growth and structure (Fig. 5.40). Ward Hunt Ice Shelf is largely composed of three types of basement ice, which are the product of a sequence of processes which transform first-year sea ice to very old multiyear sea ice, in the absence of 18 O depleted meltwater. Milne Ice Shelf is largely composed of glacier tongues which flowed into and coalesced in Milne Fjord. The ice tongues and the basement ice acted as stable platforms for further ice shelf thickening through snow and ice accumulation. The latter ... |
