Committee members will review and rank applications for the GSA/ExxonMobil Field Award in April or will create a subcommittee for this activity. The subcommittee will comprise a minimum of 4 committee members or 2 committee members and 2 members chosen from related GSA group, such as the Energy Division. The application review and ranking process involves reviewing cover letters and two letters of recommendation for each candidate and ordering the applications in accordance with application quality.
Committee Requirements:
Members must be committed to developing a better integration of applied and academic science in GSA meetings, publications, short courses, field trips, and education and outreach programs. Members must also be active in one or more GSA Divisions. Professional Interests: Environmental & Engineering Geology, Hydrogeology, Karst, Quaternary Geology & Geomorphology, Structural Geology & Tectonics, Sedimentary Geology.

Investments Committee
Committee Charge:
The purpose of this committee is to meet with the Society money managers and to inform the Council about investment of the funds, securities, and other investments of the Society.
The committee acts for the Council in deciding on the purchase or sale of securities although authority for ordering actual transactions is reserved for the president, vice-president, past president, or treasurer.
The committee shall be responsible for a report on the condition of the portfolio and shall make recommendations concerning overall policy and types of investment. The chair shall submit an annual report to be published in the Annual Report of The Geological Society of America, Inc.
Using the cash flow needs projection for the upcoming year approved by Council at the time of budget approval, the Committee on Investments, through its outside money manager, will establish a cash transfer account to implement quarterly transfers achieved in such a way that the asset allocation of funds is maintained. Transfers are then reported immediately to the Committee on Investments, and the Finance Committee. The Finance Committee will approve in advance any cash flow transfer projections that exceed the cash flow transfer projections approved by Council at the time of budget approval.
