Polar Earth Observing Network (POLENET)

Its research includes geophysical observations such as changes in magnetic fields as well as tide gauge and gravity measurements.

[2] Data is collected from equipment spanning much of the Antarctic and the Greenland ice sheets, as well as the Arctic regions of Finland, Sweden, Norway, and Russia.

[4] Antarctic Treaty nations are presently collecting seismic and geodetic measurements at their permanent research stations.

The GPS stations record movement of bedrock (solid rock under loose surface material) as changes in ice mass take place.

Seismic stations record data that allows researchers to analyze seismic data to help understand the geological issues taking place as changes in the ice sheets take place, including the strength of our planet's crust and underlying mantle.

[9] GAMSEIS deploys broadband seismometers to image the structure of the Gamburtsev Subglacial Mountains (GSM) of East Antarctica.

We are measuring the steady vertical velocity field due to isostatic rebound with GPS and will constrain earth rheology (elasticity, viscosity) through seismic studies.

[14] G-NET is maintained and developed in close cooperation with the following:[15] Like ANET, there is research that is also led by Ohio State University.
