Images of Ronne-Filchner calving event, October 1998

There are various images and 1 map in this directory:

From 13/20/1998
We have 5 versions of one image:
  1. ronne.gif (330k; 850x850) - image navigated; lat-lon's added
  2. ronne.jpg (76k; 850x850) - same as above but jpg
  3. ronne-label.gif (423k; 1000x1000) - image with explanatory text added
  4. ronne-label.jpg (121k; 1000x1000) - same as above but jpg
  5. ronne_sm.gif (57k) - same as #1 but 300x300

they show an iceberg (now named A38) calving from the Ronne iceshelf. A press release and scientific info describing the event is available. The image is channel 4 (IR).

  1. 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...)
  2. 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.
  3. 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.
  4. A few more unsorted from here [RAL].
  5. ronn15oct.gif [15/10/1998] [RAL] 2 days after our image.
  6. 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.
