An open workshop on the Arctic Gravity Field and Geophysics will be held
in Ottawa, 16 May 2001 (in connection with the Canadian Geophysical
Union meeting), see http://www.acs.ucalgary.ca/~cguconf/main.html

ARCTIC GRAVITY FIELD AND GEOPHYSICS WORKSHOP

The gravity field of the arctic region provides important constraints on
the tectonics of the Arctic Ocean and adjoining land areas, especially
when combined with other geophysical data. Recently released gravity
data, and new extensive airborne and submarine surveys have been
compiled to create a much improved and nearly complete image of the
anomalous gravity field in the Arctic Region. A working group under the
International Gravity and Geoid Commission, the "Arctic Gravity Project"
http://164.214.2.59/GandG/agp/index.htm is compiling all gravity
measurements north of 64N to produce a 5' grid by the end of 2001. This
new grid will fill one of the largest gaps in the present global gravity
coverage, resulting in major improvements for geoid determination,
satellite geodesy, and geophysics. Combined analysis of gravity with
recent compilations of arctic bathymetry and magnetics data should
result in substantial improvements in our understanding of the history
of the Arctic Ocean and the surrounding continents. We welcome papers
describing major field activities in the Arctic involving gravity and
other geophysical data, including the assessment of new survey
techniques such as airborne gravity, as well as papers using gravity
data as a constraint on arctic tectonics.
