Dear MSA Members: Please consider submitting an abstract to the GSA 2020 Connects Online<https://community.geosociety.org/gsa2020/home> meeting from 26-30 October 2020. The deadline for abstract submission is August 4, 2020, 11:59 PM Pacific Time. The subject sessions of interest (sessions endorsed by MSA, GS, GSA-MGPV, CMS, MAC, MSGBI) are listed below. You can find descriptions of these and all 250 topical sessions<https://community.geosociety.org/gsa2020/program/technical/topical> online. The traditional MSA in-person meeting events – sessions to honor awardees and the joint MSA-MGPV-GS reception have been delayed until the 2021 GSA meeting in Portland, OR. The annual meeting of MSA Members will be held virtually on Saturday, October 24, 2020 at 3:00 PM Eastern. Details on how to attend this meeting will be sent to the MSA membership in early October. The GSA abstract fee is US$25 Students / US$50 all others. Please encourage students to submit an abstract. Also, don't miss the abstract tip sheet that outlines 5 steps to the perfect abstract<https://higherlogicdownload.s3.amazonaws.com/GEOSOCIETY/d1a5fdbe-4e0c-4afb-8a3e-aef5ff47796d/UploadedImages/2020montreal/documents/preparing-abstract-gsa2020.pdf>.
