Forerunners in the Field

From the sea surface to the seafloor

MBC’s knowledge of the marine environment has grown since its founding in 1969. We maintain a team of scientific divers that adhere to the standards of the American Academy of Underwater Sciences (AAUS). Our studies of the ocean include multiple habitats, from the sea surface to the seafloor. MBC has been involved in the analysis of potential environmental impacts from seawater desalination since 2000 when new technologies revitalized interest in large-scale coastal facilities in southern California. MBC has evaluated marine resources for desalination plants located in Long Beach, Huntington Beach, Dana Point, Oceanside, Carlsbad, San Diego and Baja California, Mexico. MBC also provided technical evaluation of environmental documents for a proposed seawater desalination plant in Monterey Bay, California.

“MBC has always been a leader in marine studies and marine biology for the seawater desalination market. With all of their existing data and the quality of their data and analysis, they are a top trusted resource. We started with a great relationship 13 years ago and we'll stick together for any marine biology work moving forward."

Doheny Ocean Desalination Project

The South Coast Water District proposed the Doheny Ocean Desalination Project to produce approximately 5 to 15 million gallons per day (mgd) of potable drinking water. The project would consist of a subsurface slant well intake system, raw (sea) water conveyance to the desalination facility site, a seawater desalination plant, brine disposal through an existing wastewater ocean outfall, solids handling facilities, and potable water delivery to adjacent distribution infrastructure.
