Abstract
During two field seasons some 130 m of ice core and about 75 snow samples have been obtained from the ice shelves of northern Ellesmere Island. The ice core came from eighteen sites, whilst the snow was taken from 10 pits, at various locations. The necessity for such large and varied sampling has been demonstrated since, if it is wished to understand Arctic Ice Shelf evolution, one must study as many different types of ice as possible. Without such a comprehensive program of coring, snow sampling and analysis it would not be possible to; a) identify a characteristic delta super 18 0 value for each ice type, b) understand the processes which create those isotope signatures, c) explain how these processes are related to each other and what the relationships mean for understanding Arctic Ice Shelf evolution.
