CRUISE ANNOUNCEMENT

VESSEL: NOAA Vessel David Starr Jordan, 0407-JD, DS 04-05 (345).
CRUISE DATES: July 12 - 28, 2004.
PROJECT: CalCOFI Survey, Fisheries Resources Division.

ITINERARY: Depart San Diego, California at 0800 on July 12, 2004 andproceed to first station 93.3/26.7 (position 32° 57.4'N/117°18.3'W). To complete the proposed cruise track, it will benecessary to maintain maximum speed between stations whenever possible. Once the pattern has been completed, the ship willreturn to San Diego on July 28, 2004.

OBJECTIVES:

  1. To conduct continuous underway sampling of surface waters. Temperature and salinity will be automatically logged by computer with the output from the GPS navigational unit.
  2. To record current profiles throughout the duration of the cruise with the Acoustic Doppler Current Profiler in an attempt to estimate net transport in the northern region.
  3. To continue an ongoing assessment of pelagic fish stocks between La Jolla and Avila Beach, California.
  4. To monitor environmental conditions within the CalCOFI survey area.
  5. To make continuous observations of sea birds and marine mammals.
  6. To record continuous acoustic targets obtained with the EK-500 scientific sounder.

PROCEDURES:

1. Each standard CalCOFI station will include the following:

  • A CTD/Rosette consisting of 20 10-liter hydrographicbottles 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, depthpermitting, using paired 505 µm mesh netswith 71 cm diameter openings. An Optical Plankton Counter will be mounted in the port side of the frame to record time,depth and size fractions of the sampledplankton, in situ. The technical requirements for this tow are: Descent rate of 50 meters per minute. All tows with ascending wire angles lowerthan 38° or higher than 51° in the final 100 meters ofwire will be repeated. Additionally, a 45° wire angleshould be closely maintained during the ascent anddescent of the net frame.
  • A Manta net (neuston) tow, using a 505 µm mesh net on aframe with a mouth area of 0.1333 m⊃2;.
    • 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 diameter150 µm mesh nets. The technical requirements for thePairovet 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.
    • During transit between stations, a bird observer will berecording location and species of various sea birds and marine mammals
    • At about 1100 hours each day of the cruise a primaryproductivity 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 is to collectwater from 6 discrete depths for daily in situ productivity experiments. Measurements of extracted chlorophyll and phaeophytin will be obtained with a fluorometer. Primary production to be measured as C14uptake in a 6 hour in situ incubation. Nutrients will be measured with an auto-analyzer. All radioisotopework areas will be given a wipe test before the departure of the SIO technical staff.
    • A light meter (Secchi disc) will be used to measure thelight intensity in the euphotic zone once a day with theprimary productivity cast.
