We have 5 versions of one image:

they show an iceberg (now named A38) calving from the Ronne iceshelf.

- location-map.13-10-1998.300.gif (8k) - location map - the purple dot
represents the location (but not size!) of the berg; the green crosses mark the approximate
corners of the picture "ronne.gif" (according to my calculations...)
- ronn_11.gif [11/10/1998] [RAL] 2 days earlier than our image.
Navigated and with Berkner island outlined in green, which helps location. Glaciologically
shows nothing new, but very interesting meteorologically - look at the bands visible just inland of the
berg (and in the gap too). Unlikely to be anything other than clouds.
- ronn_20.gif [20/09/1998/] [RAL] This is pre-calving but
rather dark & you don't see much. The "edge" is not the ice front, but the edge of the fast ice.
- A few more unsorted from here [RAL].
- ronn15oct.gif [15/10/1998] [RAL] 2 days after our image.
- 03-11-1998.jpg (600k; 1002x1000) - shows the berg broken up; and also a
rather nice mesocyclone over the iceshelf
Smaller version and map
The smaller image from the 13th and the location map are displayed below:
In Austral summer 94/95 the ice shelf around James Ross Island disintegrated and parts of the Larsen ice shelf calved.
This is documented at http://www.nbs.ac.uk/public/icd/bas_publ.html. Please do not confuse the 2 events...
Perhaps this is a good point to remind people about the
naming of icebergs.

I guess other people will put up stuff too. When I find it I'll try to link it in.
Calving event spotted by Mark Jefferey at Rothera - thanks Mark!
