Permafrost Monthly Alerts (PMAs)

The U.S. Permafrost Association, together with the American Geosciences Institute (AGI), is pleased to provide our members with the Permafrost Monthly Alerts (PMAs).

What is the PMA Program?

The PMA Program is an online library of permafrost-related references reviewed by experts in permafrost sciences and compiled monthly by the American Geosciences Institute (AGI). The AGI GeoRef service regularly scans the contents of over 3,500 journals in 40 languages from the global geosciences literature, comprised of approximately 345 different sources. In addition to journals, special publications such as papers in proceedings, and hard-to-find publications are provided.
