1) IAGA Resolution #4
(Buenos Aires,
Argentina,
Aug. 1993)
IAGA
noting the international interest in
Antarctic geology because of Antarctica’s
central position in Gondwanaland, resulting in
a large number of geophysical surveys in
Antarctica, and noting
the success of collaborative efforts
in making a map and digital database of
magnetic anomalies for the Arctic region,
recommendsthat all countries carrying out research
in Antarctica of relevance to geomagnetism
cooperate with the IAGA Working Group V.9
subcommittee on magnetic anomalies of the
polar regions for the production of a database
for a magnetic anomaly map of Antarctica and
its surrounding oceans.
2) SCAR Recommendation
XXIII-5 (Rome, Italy, Aug. 1994)
recognizingthe value of regional
magnetic compilations for enhancing the
understanding of continental-scale geological
features and encouraging further work, and
notingIAGA WGV.9 Resolution #4 (1993), the
Solid Earth Geophysics Working Group
recommends the creation and publication
of a magnetic anomaly map and digital database
for the Antarctic continent and surrounding
oceans, and encourages all countries holding
magnetic data to contribute those data to the
project.
3) IAGA Resolution
#1 (Uppsala, Sweden, Aug. 1997)
IAGA
notingthe ability of
satellites to provide unparalleled spatial and
temporal coverage of observations of the
Earth’s magnetic and gravity fields, and
recognizingthe revolutionary contribution that an
extended time-series of such observations
would make to a wide spectrum of geoscientific
and space science studies, and
welcomingthe present plans by several nations to
launch potential-field satellites within the
next 5 years,
considersthat now is a favorable time for an
international effort to promote and coordinate
satellite surveys to achieve, for the first
time, continuous monitoring of geopotential
field variability in the near-Earth
environment, and recommendsthat an “International
Decade for Geopotential-Field Research”
be declared to provide an international focus
for such efforts
4) IAGA
Resolution #1
(Uppsala, Sweden,
Aug. 1997)
IAGA
recognizingthe importance of
obtaining world-wide coverage of gravity and
magnetic data, and
recognizingthe technical difficulties of routing
satellites over regions close to the
geographic poles,
urgesthe community to consider using
conventional land, marine, and airborne
methods for completing gravity and magnetic
anomaly coverage in the polar regions.
