The data for this program originates from the Central Bight Water Quality Program. This program is a collaborative program between the Orange County Sanitation District (OCSD), the County Sanitation Districts of Los Angeles County (LACSD), the City of Los Angeles Department of Sanitation (Hyperion), and ABC Labs for the City of Oxnard (Oxnard).
This program has been conducted quarterly from July 1998 through the present. All sampling is conducted using Seabird CTDs at fixed stations and using similar methods. In most cases, the entire grid is sampled in a three to four day period.
Data from the monitoring stations maintained by City of San Diego for the Point Loma Ocean Outfall permit and the International Boundary Water Commission's (IBWC) South Bay Ocean Outfall are integrated to allow access to the hydrography data gathered by the major EPA NPDES permit holders in Southern California.
