To understand the dynamics of onshore-offshore shore hydrologic systems, this IODP- and ICDP-sponsored workshop will focus on the coupling between glacial dynamics, sea-level variations, and groundwater flow for Martha’s Vineyard, Massachusetts, USA and the U.S. Atlantic continental shelf offshore Martha’s Vineyard. The overall goals of the workshop (May 22-23, 2017; Woods Hole, Massachusetts), are to develop a new operational plan for IODP Proposal 637 and establish an amphibious component of the project to accomplish its science objectives. These goals will be accomplished by (1) developing ideal sampling and measurement plans for geology, geophysics, geochemistry, and microbiology across the shoreline and the shelf; (2) prioritizing onshore and offshore scientific operations including site order and target depths; and (3) formulating specific plans for pursuing external funds for the drilling project. Travel support is available for a limited number of participants through USSSP (for U.S.) and ICDP (for international). For more information, visit the workshop website. The workshop is open to U.S. and international participants and the deadline to apply is February 17, 2017.
