Section
Objectives of Workshop:
Initiate preparation of a Circum-antarctic Map of
Permafrost and Ground-Ice Conditions
Initiate preparation of soil maps of the Southern
Hemisphere, antarctic region, McMurdo Dry Valleys
Design and organize a database for Antarctic soils
and permafrost/ground-ice conditions
Develop a permafrost monitoring network for
Antarctica, including drilling and equipping boreholes
for long-term measurement of permafrost
temperatures
Support/expand circum-antarctic active-layer
monitoring program
Identify future needs and priorities

Some Methods for Mapping Permafrost and
Soils:
Satellite images/remote sensing (M. Prentice et al.,
B. Csatho et al.)
GIS technology (N. Bliss)
Digital elevation models (DEMs) (R. Sletten et al.)
Magnetotelluric soundings (E. Borzatta and D.
Trombotto)
Ground-penetrating radar (S. Arcone and M.
Prentice; Augustinus et al.)
Simulation models
– PERMAMODEL (M. Ramos et al.)
