Fall 2019 California Cooperative Oceanic Fisheries Investigations Survey

November 15, 2019

November 4–19, 2019, R/V Oceanus sails between Morro Bay and La Jolla, California assessing pelagic fish stocks and monitoring environmental conditions.

The 2019 Fall California Cooperative Oceanic Fisheries Investigations survey is scheduled for November 4-19, 2019, aboard R/V Oceanus. The vessel will attempt to occupy station locations between Morro Bay and La Jolla, California. The survey is an ongoing assessment of pelagic fish stocks and monitors environmental conditions within the survey area. Researchers will conduct continuous underway sampling of surface waters; temperature, salinity, chlorophyll, and various other meteorological data will be logged for future assessment. Researchers will record profiles throughout the duration of the cruise with an Acoustic Doppler Current Profiler. The survey will also measure optical profiles within the California Bight, including pigment concentration and particle absorption.

As of November 15, participants on the current California Cooperative Oceanic Fisheries Investigations survey had completed 60 of the 75 planned stations for the fall 2019 cruise. Thanks to mild weather conditions and R/V Oceanus making twelve knots between stations, it is likely that the survey will be finished ahead of schedule. Early results indicate that the Southern California Bight may be returning to more “normal” conditions as ocean temperatures are closer to their 50-year harmonic mean. The ship is scheduled to return to San Diego on Tuesday, November 19.

On Monday, November 4, the UNOLS vessel R/V Oceanus departed from the Nimitz Marine Facility to begin the fall California Cooperative Oceanic Fisheries Investigations survey in the 70th year of the program. The goal over the 16-day survey is to occupy all 75 stations ranging from San Diego up to Avila Beach from the coastal region out to approximately 300 nautical miles offshore. Samples taken at stations in the Southern California bight and the California Current will consist of physical and chemical seawater measurements as well as ichthyoplankton collections.
