| Description |
Our ultimate objective for this SGD project is to be able to make accurate generalizations and predictions regarding rates and ecological consequences of SGD under differing hydrogeologic, geographical and climatological regimes. This collective work will thus permit a first-order national assessment of coastal SGD impact. Current research goals, as specified in the 2011 Coastal Aquifer Project II Science Plan, include:Goal A. Design projects that will provide new, key information on climate change related impacts to nearshore ecosystems. Goal B. Develop projects that examine hydrologic controls on coastal vulnerability and susceptibility (e.g. cliff/bluff erosion and failure, marsh fragmentation due to changes in surface water-groundwater exchange, etc). Goal C. Design projects that will yield refined estimates of fresh (terrestrial) and saline (marine) groundwater discharge and associated chemical loads, and importantly, also provide an assessment of the whole watershed and of the seasonality of these exchanges.Goal D. Provide new information on geochemical and biogeochemical transformations in groundwater discharge zones and subterranean estuaries. Goal E. Extend physcial and geochemical findings of land / sea exchange to assess nearshore ecosystems impacts by collaborating with scientists that use cutting-edge molecular microbiological techniques. |
