Summary of Field Work: |
1. Each standard CalCOFI station will include the following:
a. A CTD/Rosette consisting of 24 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,
chlorophylls and phytoplankton. On stations 90.0 90.0 and
80.0 90.0, the CTD/Rosette will be lowered to 3500 meters.
On line 66.7, the CTD/Rosette will be lowered to 1000 meters.
b. 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, ascent rate of 20 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.
c. A Manta net (surface) tow, using a 505 µm mesh net on a
frame with a mouth area of 0.1333 m².
d. Weather observations.
e. 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.
f. A PRPOOS(Planktonic Rate Processes in Oligotrophic Ocean
Systems) net tow will be taken at all stations on line 90.0
and 80.0 as well as stations out to and including station
70.0 on lines 86.7 and 83.3. These stations are occupied as
part of the LTER(Long Term Ecological Reserve) project. The
mesh of the PRPOOS net is 202 µm and the tow is a vertical
cast up from 210 meters.
g. 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 is to 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 to 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.
h. A light meter(secchi) will be used to measure the light
intensity in the euphotic zone once a day with the primary
productivity cast.
i. A MOHT(Oozeki) pelagic trawl will be deployed on
approximately 20 night time CalCOFI stations within the
standard CalCOFI grid(lines 76.7 to 93.3). This will
encompass both adaptive and non-adaptive sampling in
conjunction with the EK-60. The Oozeki is a fixed-frame
trawl with a 5.5 m² mouth opening that can be towed at speeds
up to 4-5 knots. It is designed to capture a variety of
organisms including krill, late larval and juvenile fishes,
and micronekton. The Oozeki data will be used to groundtruth
the EK-60 acoustic data as well as collect samples of
juvenile fishes for the study of sardine recruitment
processes.
j. During transit between stations, a bird observer and
three mammal observers will be recording location and species
of various sea birds and marine mammals.
k. During transit between most daylight stations, an
acoustic hydrophone array will be towed off the stern with a
cable/winch to record sounds from marine mammals. Upon
approaching a station, a sonobuoy will be deployed one
nautical mile prior to stopping for station work.
l. During the grid occupation, the CUFES pump will run
continuously between stations to sample pelagic fish eggs.
The CUFES pump/pipe will be hull mounted to draw water from a
depth of three meters into a scientific laboratory van on the
main deck, port side. |
