CRUISE ANNOUNCEMENT (PDF Version)

VESSEL: NOAA Vessel David Starr Jordan, 0401-JD, DS 04-01.

CRUISE DATES: January 5 - 30, 2004.

PROJECT: CalCOFI Survey, Fisheries Resources Division.

ITINERARY: Leg I: Depart San Diego, California at 0800 on January 5, 2004. Proceed to first CalCOFI station 93.3/26.7 (position 32E 57.4'N/117E 18.3'W) and begin a modified CalCOFI pattern. To complete the proposed cruise track, it will be necessary to maintain maximum speed between stations whenever possible. The vessel will stop on or about January 11 to exchange personnel in Dana Point, California.

Leg II: Once personnel exchanges are complete, the Jordan will continue to occupy stations up to Avila Beach, California. The vessel will stop on or about January 19 to exchange personnel in Avila Beach.
Leg III: Once personnel exchanges are complete, the Jordan will continue to occupy stations up to Monterey, California. The vessel will stop on or about January 22 to exchange personnel in Monterey.
Leg IV: Once personnel exchanges are complete, the Jordan will continue to occupy stations up to San Francisco. The vessel will return to San Diego on January 30, 2004.

OBJECTIVES:

To continue an ongoing assessment of pelagic fish stocks between La Jolla and San Francisco, California.
To monitor environmental conditions within the CalCOFI survey area.
To conduct continuous underway sampling of surface waters. Temperature, salinity and chlorophyll will be automatically logged by computer with the output from the GPS navigational unit.
To record current profiles throughout the duration of the cruise with the Acoustic Doppler Current Profiler (ADCP).
To make continuous observations of sea birds and marine mammals.

PROCEDURES:

Each standard CalCOFI station will include the following:

A CTD/Rosette consisting of 20 10-liter hydrographic bottles will be lowered to 500 meters (depth permitting) to measure physical parameters and collect water at discrete depths for analysis of: oxygen concentration, salinity, nutrients, chlorophyll and phytoplankton.
A CalBOBL (CalCOFI Bongo) standard oblique plankton tow with 300 meters of wire out, depth permitting, using paired 505 µm mesh nets with 71 cm diameter openings. The technical requirements for this tow are: Descent rate of 50 meters per minute. All tows with ascending wire angles lower than 38° or higher than 51° in the final 100 meters of wire will be repeated. Additionally, a 45° wire angle should be closely maintained during the ascent and descent of the net frame. The Bongo frame will fitted with a self contained OPC (Optical Particle Counter) mounted inside the port side opening.
A Manta net (neuston) tow, using a 505 µm mesh net on a frame with a mouth area of 0.1333 m².
Weather observations.
A Pairovet (vertical) plankton tow will be taken at all stations inshore of, and including station 70. The Pairovet net will be fished from 70 meters to the surface (depth permitting) using paired 25 cm diameter 150 µm mesh nets. The technical requirements for Pairovet tows are: Descent rate of 70 meters per minute, ascent rate of 70 meters per minute. All tows with wire angles exceeding 15° during the ascent will be repeated.
Up to and including line 77, at about 1100 hours on each day of the cruise, a primary productivity CTD cast consisting of six 10-liter hydrographic bottles will be carried out. The cast arrangement will be determined by a Secchi disc observation. The purpose of the cast isto collect water from 6 discrete depths for daily in situ productivity experiments. Measurements of extracted chlorophyll and phaeophytin will be obtained with a fluorometer. Primary production will be measured as C14 uptake in a 6 hour in situ incubation. Nutrients will be measured with an auto-analyzer. All radioisotope work areas will be given a wipe test before the departure of the SIO technical staff.
A light meter will be used to measure the light intensity in the euphotic zone once a day with the primary productivity cast.
During transit between stations, a bird observer will be recording location and species of various sea birds and marine mammals.

The egg pump will be mounted inside the ship’s hull drawing water from a depth of three meters. This will only be a test run of a new pump system to be installed on the Jordan. The system will only be used periodically at the discretion of the chief scientist and watch leaders.
