Oceanography and Sediment Sampling

ADH provides professional capabilities and expertise in environmental and physical oceanographic studies as detailed below. ADH staff has performed such studies for both governmental and private sector clients at various locations throughout California. ADH staff has experience providing input, evaluation and development of many aspects related to the following: Illustration, as excerpted from SAIC and ADH report, San Francisco Marina West Basin, Sand Deposition Conceptual Model, July 6, 2006, that show ocean wave patterns incoming to the San Francisco Marina breakwater depositing sand by littoral longshore drift to the east along the Marina West Basin breakwater and entrance channel. Shore-based water sampling data is used to model dye dilution in the receiving water.
