Regional workshops develop drilling strategies for specific areas.
Travel support is limited to U.S. participants, though the workshop must be open to any interested party. It is up to the workshop convenor whether each participant's travel will be fully supported or defrayed up to a specified limit. If workshops are to be held outside of the U.S. the proposal must present appropriate justification including cost analysis relative to U.S. locations. A statement of openness must also be included, which indicates that participation and funding are not linked. The P.I. will be notified of the results of the review within about two months.
