Iceberg Motion
Most iceberg material herein is provided by Professor Doug MacAyeal from the University of Chicago
- Here is a movie in Quicktime format that shows the formation of the C-18 and C-19 icebergs. Note that this is a very long
sequence of over 220 images that may take some time to download. Also note that this animation does not have any navigation corrections made to the images (so the Ross Ice Shelf
jumps a bit).
- Here is the latest two year movie of the iceberg as seen from the NOAA series and some DMSP series satellites from
March of 2000 to March of 2002. Note that this is a very long sequence of over 220 images that may take some time to download. Also note that this animation does not have any
navigation corrections made to the images (so the Ross Ice Shelf jumps a bit). The amination looks best if the speed is increased to nearly 90% of the full speed.
- This animation shows the outlines of
B15a, C16, Ross Island, Ross Ice Shelf ice front, Beaufort Island, Franklin
Island and the Victoria Land coast through the period from January 25, 2001
to December 31, 2001. Each frame of the animation shows the position of B15a
at 00:00 UTC on each day of the period. The red line segment emanating from
the station (Mother 1) on B15a represents the wind direction. The length of
the line segment is proportional to the wind speed, when the wind speed is
below 3.6 m/s; and is of fixed (maximum) length when the wind speed is
greater than or equal to 3.6 m/s. During periods when B15a was colliding
with the Ross Ice Shelf or Ross Island, overlapping occurs between the
outlines of B15a and the feature being collided with. This overlap
represents the region where damage to the iceberg or the Ross Ice Shelf
led to "trimming" of the outline. The initial outlines ob B15a and the
Ross Ice Shelf (based on their 25 January, 2001, status) were used,
however, in all frames of the animation. This animation was made using
Matlab (Stereographic projection, N to the left) and data collected by
the iceberg research project performed through the collaboration of
University of Wisconsin with University of Chicago. (Quicktime Movie)
- This animation is similar to the
movie above, except that satellite imagery is used as background and outline
for the various objects in the Ross Sea. Each frame represents one day during
the Jan 25, 2001 to Dec. 31, 2001 time period. This animation was created
using field data from the iceberg research project by Kelly Brunt, of the
Raytheon Polar Services Corporation. (Quicktime Movie)
- This animation shows the
response of the sea ice and icebergs in the Southwestern Ross Sea during a 5
day period surrounding a period of strong Southerly winds in the Ross Sea. The
animation begins on or about 12 December and lasts till about 17 December,
2001. This animation was obtained from the "ice research" page of the JPL/NASA
web site. For attribution and citation information, please refer to the

- Here is a sample movie from
NOAA-12, -14, -15, and -16 showing the movement of the icebergs just to the
north of Ross Island, Antarctica as well as the rapid growth and the slow
decay of the fast ice between McMurdo Sound and the Drygalski Ice Tongue.
(From March 20, 2001 to October 24, 2001)
- Animations of sea ice and icebergs
- as seen from scatterometer data from Dr. Mark Drinkwater, ESA and Dr.
David Ling, BYU (Animations are in AVI and animated GIF format)
- Antarctica (masked) from July 19, 1999 to July 8, 2000.
- Antarctica (average) from January 1, 2000 to August 9, 2000
- Motion of B-10A and A-22B Icebergs from
October 1-25, 1999
- Ross Sea section from March 30, 2000 to August 13, 2000 (including the B-15/B-17 icebergs!)
- Weddell Sea section from May 16, 2000 to August 12, 2000 (showing the A-43/A-44 icebergs!)
- The Arctic from July 19, 1999 to December 31,1999
- Animations of the Ross and Ronne Ice Shelf Icebergs {simulated}. (Animations are in
Quicktime format; summaries are Adobe PDF files):
- This display is an interferogram
derived from the ERS satellite showing what was going on in the area B-15
broke away from in January of 1996, four years before B-15 was created.
- Here are the model domain and
model mesh used to simulate the iceberg's motion.
