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/11718.3'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 m 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 m 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 m 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.
