Data Summaries

The Marine Invasive Species Program monitors and analyzes vessel arrival patterns at all California ports. Staff obtains arrivals data from the Marine Exchanges of Southern California and the San Francisco Bay Region and ballast water data from the vessel-submitted reporting forms.

By Vessel Type

Bar graph showing the number of arrivals to all California ports during the first two quarters of 2022 (January to June) separated by vessel type. Containers ships accounted for more than 1500 arrivals, followed by tankers with about 1250 and bulk vessels with approximately 800; the rest of the vessel types had less than 500 arrivals during the two quarters of 2022.

By Port

Bar graph showing the number of arrivals to all California ports in during the first two quarters of 2022 (January to June) by port. Los Angeles and Long beach Port complex received more than 2000 arrivals followed by San Francisco with approximately 750 and Oakland, Carquinez and Richmond with total arrivals between 250 and 500. All the other California ports received less than 250 arrivals.

By Vessel Type

Bar graph showing the total volume discharged in California ports during the first two quarters of 2022 (January to June) by each vessel type. Bulk vessels have discharged more than 2.5 million metric tons of ballast water, followed by tankers with approximately 1.6 million metric tons.

By Port

Bar graph showing the total volume discharged in California ports during the first quarter of 2022 by port. Los Angeles Long beach port complex have received about 1 million metric tons of ballast water followed by Richmond with 0.5 and Stockton with 0.3 million metric tons.
