Marine Exchange of Southern California

The Marine Exchange of Southern California is a maritime information center and vessel traffic service non-profit headquartered in San Pedro, California. While its primary monitoring domain anchors the ports of Los Angeles and Long Beach, its broader regional operations heavily integrate with the San Francisco Bay Area through Pacific Maritime Management Services (PacMMS). This collaborative operational framework links MXSocal with SFMX to manage joint sea traffic databases, optimize cross-border vessel queuing lists, and standardize maritime communications across all major California port systems.
