I. Overview

  1. Brief Summary and Project Period:  Survey the distributions and abundances of pelagic fish stocks, their prey, and their biotic and abiotic environments in the area of the California Current between San Diego, California and Avila Beach, California during the period of 9-24 November 2017.
  2. Operating Area:  From San Diego, CA to Avila Beach, CA and out 400 nautical miles. Please refer to Station Order & Coordinates PDF
  3. Summary of Objectives: Survey the distributions and abundances of pelagic fish stocks, their prey, and their biotic and abiotic environments in the area of the California Current between San Diego, California and Avila Beach, California.
    1. I.C.1. Continuously sample multi-frequency acoustic backscatter using the Simrad EK80. The data will be used to estimate the distributions and abundances of coastal pelagic fishes (e.g., sardine, anchovy, and mackerel), and krill species.
    2. I.C.2. Continuously sample sea-surface temperature, salinity, and chlorophyll-a using a thermosalinograph. These data will be used to estimate the physical oceanographic habitats for target species.
    3. I.C.3. Continuously sample air temperature, barometric pressure, and wind speed and direction using an integrated weather station.
    4. I.C.4. Sample profiles of seawater temperature, salinity, chlorophyll-a, nutrients, and phytoplankton using a CTD with water-sampling rosette and other instruments at prescribed stations. Measurements of extracted chlorophyll and phaeophytin will be obtained with a fluorometer. Primary production will be measured as C14 uptake in a six hour in situ incubation. Nutrients will be measured with an auto-analyzer. These data will be used to estimate primary productivity and the biotic and abiotic habitats for target species.
    5. I.C.5. Sample the light intensity in the photic zone using a standard secchi disk once per day in conjunction with a daytime CTD station. These data will be used to interpret the measurements of primary production.
    6. I.C.6. Sample plankton using a CalBOBL (CalCOFI Bongo Oblique) at prescribed stations. These data will be used to estimate the distributions and abundances of ichthyoplankton and zooplankton species.
    7. I.C.7. Sample plankton using a Manta (neuston) net at prescribed stations. These data will be used to estimate the distributions and abundances of ichthyoplankton species.
    8. I.C.8. Sample the vertically integrated abundance of fish eggs using a Pairovet net at prescribed stations. These data will be used to quantify the abundances and distributions of fish eggs.
    9. I.C.9. Sample plankton using a PRPOOS (Planktonic Rate Processes in Oligotrophic Ocean Systems net) at all prescribed CalCOFI stations on lines 90.0, 86.7, 83.3 and 80.0 only. These data will be used in analyses by the LTER (Long Term Ecological Research) project.
    10. I.C.10. Continuously observe, during daylight hours, mammals. These data will be used to estimate the distributions and abundances of marine mammals.
    11. I.C.11. Deployment of four expendable wave measuring drifters at the offshore end of CalCOFI lines.
