
Joint effort with Japan,
New Zealand, USA
Reconnaissance during
IGY 1959
Drilled post-IGY 15 cores,
2 km total
Goal was to study past 10

Soils Database


Bockheim , students, & colleagues from 1975 to
1987, 481 soils
Archived with National Snow and Ice Data
Center (NSIDC)
(http://nsidc.org/data/docs/fgdc/ggd221_soiltemp_antarctica/index.html)


Compliments database of Ian Campbell from
New Zealand
Included in VALMAP and other soil maps
Global Terrestrial Network for
Permafrost (GTN-P)

Initiated by the International Permafrost Association (IPA)
Organize and manage a global network of permafrost observatories
for detecting, monitoring, and predicting climate change
Authorized under the Global Climate Observing System (GCOS)
Permafrost and Climate in Europe (PACE) contributions

Two components



1)
2)
Circumpolar Active Layer Monitoring (CALM) network which was
established in 1990 active layer (the surface layer that freezes and
thaws annually)
Monitor the thermal state of the underlying permafrost primarily using
deep boreholes
