Offshore Geophysical Survey

The Offshore Geophysical Survey is intended to support the evaluation of the possibility of a subsurface intake off the Santa Cruz shoreline, as well as to support the proposed project specific EIR and permitting. A Technical Working Group (TWG) has been formed to provide review throughout the study.

 

 EcoSystems Management Associates (ECO-M) is currently performing the offshore geophysical study for scwd².   The primary task to be completed includes:

• Conduct geophysical surveys (Alluvial Basin Survey) south and west of the San Lorenzo River outlet and southeast of Neary’s Lagoon  

The work includes geophysical surveys (multibeam, sub-bottom, and high- resolution multi-channel seismic reflection profiling), confirmation soil sampling (vibracoring), and laboratory and hydrogeological services to determine the subsurface stratigraphy and the potential for offshore saline groundwater production.

 

The objective of the alluvial basin survey is to identify the location, dimensions, and depth of the potential offshore portion of an alluvial basin associated with the San Lorenzo River, and to provide an initial characterization of the type of sediments filling the basin. The findings will be used to determine the potential for a subsurface intake using slant wells or an engineered infiltration gallery.

 

 

Geophysical Study Locations to determine if potential alluvial basin can support a subsurface slant intake well or an infiltration gallery.
