Island Submarine Groundwater Discharge

Active Dates: 2014-

Participants: CSULB: Matt Becker, Tanya (Zeferjahn) Brosnan, Michelle Baroldi
Collaborators: Carl Lipo, SUNY Binghamton, Chris Lee CSULB

Support: Conrey Endowment, NSF REU Program

Groundwater seeping from the perimeter of islands has an impact on coastal geochemistry and reef communities. In addition, ancient, and some modern, societies rely upon submarine groundwater discharge (SGD) for water supplies. Our research on SGD has been carried out on Easter Island (Chile), Moorea, Tahiti (French Polynesia), and Santa Catalina Island (California).
