Dear all,

I think this may be a long shot but here goes:

I am looking for oxygen isotope data for the Riiser-Larsenisen Ice Shelf on
the Eastern edge of the Weddell Sea at about 72 degrees south. I anticipate
that the surface compositions will be close to the mean annual isotope
composition of precipitation at Halley Bay at the southern tip of the Brunt
Ice Shelf (76 degrees S). What interests me is does there exist any data
for the base of the interior and base of the shelf. Looking at maps of
Antarctica it is not immediately apparent what the catchment of the shelf
is like, how deep it penetrates into the Antarctic continent, and what age
the ice may be at the base.

To put readers in the picture I have some isotopic data for coastal waters
just off the shelf that indicate that the sea is mixing with a glacial end
member of ca. -30 per mille. I'd like to confirm that this number is
reasonable for this shelf.
