Ice Plate Trackers

02 August 2009

Recently analysis of the positions of the ‘Ice Island Trackers’ on ice Plate_A and Plate_D indicate no detachment from the Petermann Glacier, so far . The iceberg trackers are very useful for ‘early warning’, especially, as the Greenpeace ship ‘Arctic Sunrise’ is currently located in front of the Humboldt glacier, 120 kilometer south of the Petermann Glacier.

The images below illustrate
a. Dr. Jason E. Box installing an ‘ice plate tracker’ on Plate_D of the Petermann Glacier on 15 July 2009.  The ‘ice plate trackers’ will become significant if ‘Petermann Glacier Plate_D’ detaches from the glacier and becomes ‘Petermann Glacier Ice Island_D’.
b. Dr. Alan Hubbard returning to the Greenpeace helicopter after checking the Dr. Alberto Behar, NASA JPL, provided ‘expendable GPS’ to the left of the ‘Ice Island Tracker / Detachment Early Warning tracker’.
