Notes -
Operations will consist of side-scan sonar work, CHIRP and Uniboom

ROV surveys, scuba diving surveys, weather studies, rawindsonde
launches, bird surveys, deep-sea current meter retrieval/placement
and plankton trawls.


Operational Plans


The following plans can only be considered a guide as to how the
to predict weather, operations, scheduling problems and equipment
failures:


a) Benthic Coring/Side-Scan Sonar/CHIRP/Uniboom:
Benthic cores will be taken in water depth not exceeding 300
meters with a box corer. Core samples will be analyzed and
stored. At each coring site, a SeaCats cast using the
McArthur's SeaCats is requested.


A sub-surface profiler fish, the "CHIRP," will be towed before
and during coring operations. At other times, the CHIRP will
be used exclusive of the Coring operations. (A Uniboom may be
aboard during parts of the cruise as a backup to the CHIRP.


Side scan surveys will be conducted by USGS personnel.


One of the analysis performed will be with a Gamma-ray
Attenuation Porosity Evaluator (GRAPE), which uses a Cs-137
gamma-ray source. The personnel bringing this equipment aboard
will provide a copy of his/her NRC permit, and the associated
safety protocol and precautions. The NRC permit holder will be
soley responsible for the safe operation and storage of the
GRAPE device.


b) Benthic Organisms:
Working in conjunction with the coring project above,
biologists from UCSC will be on board to opportunistically
sample organisms that come to the surface in the cores.


c) ROV:
An ROV from NASA-Ames will be used for stereo video transects
over the tops and sides of 3-6 offshore pinnacles along the Big
Sur coast. These will provide baseline data on biodiversity,
distributions and abundances of larger invertebrates, algae and
rockfishes. The ROV has a 340m tether and is controlled from
the ship. Two pinnacles will be examined on each of three days.
The ROV data will also be used to select dive sites for the
second leg.


d) SCUBA Diving:
With data from the ROV dives as a guide, the six offshore
pinnacles between Pt. Pinos and Big Creek will be surveyed for
biodiversity, using photography and collection/abundance
measurements of organisms. Dives will be between depths of
30-100'. We estimate 6 dives per pinnacle (site), for a total
of 36 dives for the project. A dive plan approved by the
Director of the NOAA Diving Program will be provided to the
ship before any research dives are conducted. The dive plan
will include the names of all potential divers. Ship divers
may be asked to participate in these dives.


e) Weather:
Three 24-hour periods are required to sample diurnal cycles in
the near coastal winds. Sampling consists of surface
meteorological observations and Rawinsonde launches at
intervals of 1-3 hours. Prior to ship departure, scientists
will mount sensors on the ship at locations relatively free
from superstructure. A drifting buoy may be launched as part
of this project. During the second leg, Rowinsonde launches
will also be made as time permits.


f) Plankton Study:
Plankton trawls will be conducted opportunistically. The
plankton nets can be hand operated, but easier from a small
winch. They consist of metal rings 0,5 or 1.0 meters in
diameter plus a 2-meter long mesh bag.


g) Deep-Sea Current Meter:
This work will consist of:
1) Acoustically communicating with the current meter at
36.45N, 122.63W and sending its release command with an
over-the-side transducer,
2) Picking up the current meter string upon location at the
surface,
3) Deploying a replacement current meter string to be brought
aboard,
4) Survey-in and communicate with the current meter, so that
we are assured of successful functioning.
The mooring is in about 3200 m of water. The mooring anchor
will stay on the bottom and the mooring will float to the
surface sans anchor. There is only about 50 m of mooring cable
which can be faked on the deck. The recovery will require use
of the deck capstan to pull the mooring up over the A-frame
from the surface.


h) Bird Surveys:
Systematic observations of the distributions, abundances,
behavior and correlated environmental conditions will be made
opportunistically during daylight hours, using personnal
binoculars as well as the ship's 25x150 instrument mounted on
the flying bridge.

not be possible to use the aft crane to unload gear
in Monterey because of the pier design. Furthermore,
weather may prevent the ship from reaching the pier.
Therefore, plans should be made to unload only gear
which can be hand carried.)

operations.
3) Conduct opportunistic plankton trawls.


April 15 Dock in Monterey in early morning.
Transfer personnel and equipment; depart Monterey by 0900.
(Note that it may not be possible to use the aft crane
to unload gear in Monterey because of the pier design.
Furthermore, weather may prevent the ship from reaching
the pier. Therefore, plans should be made to unload
only gear which can be hand carried.)

Notes from USGS Bulletin
Brian Edwards, Rob Kayen, and others from USGS, on Monday completed a
marathon box-coring program on the Monterey Bay Sanctuary shelf, collecting
a total of 108 box cores. Brian and Hank Chezar continued on NOAA's ship
McArthur for a several-day program to biologically explore the "Pinnicles"
area, southwest of Monterey, with a new ROV of NASA's, where they hope to
help NASA and ourselves learn of the utility of their new ROV, with an eye
to future use. Jim Gardner, one of the architects of this sampling and ROV
program, looked on from the shoreline (or from his porch in Montara),
domiciled for the week with homemaker duties.


MBNMS Sampling Begins: The Monterey Bay National Marine
Sanctuary (MBNMS) Project recently completed 9+ days of bottom
sampling on the continental shelf between the Golden Gate and
Carmel and 3 days of ROV work on pinnacles off the Pt. Sur coast.
During the sampling work, we occupied 108 stations as part of a
cooperative effort between BUSGS, EPA, NOAA, Calif. Dept. Fish &
Game (CDFG), and the UCSC biology department. We sited sampling
locations in a randomly located statistical pattern developed in
conjunction with EPA's EMAP design criteria. Box core samples were
collected for sedimentological (BUSGS), pollution (BUSGS & CDFG), and
macro- and micro-biological (USGS & UCSC) studies. As appropriate,
box cores were sub-cored with the Kayen subsampling device and
sub-cores were analyzed on-board with the Schultheiss Whole-core
Logging System. All other analyses will be completed in shore-
based laboratories. In addition, we collected CHIRP high-resolution
seismic-reflection profiles between sample sites as well as in
three small surveys off the San Lorenzo, Pajaro, and Salinas Rivers
in an effort to map recent flood deposits. We recovered distinct, but
thin flood layer deposits (very soupy, highly oxidized muds) three to
five miles offshore of the river mouths (< 0.5 cm thick off the San
Lorenzo, and about 2 cm thick off the Pajaro and Salinas rivers).
These deposits were too thin to be resolved by the CHIRP system.
NOAA provided the free ship-time on their "Class III" 175-foot-long
McARTHUR and organized a press conference and dignitary walk-
through of the McARTHUR at the end of the sampling leg.


We coordinated the ROV work between NASA and the UCSC biologists
as preparation for UCSC diver surveys of pinnacles off the Pt. Sur
coast. NASA's interest in this effort was 1) to use their small 250
pound vehicle in open ocean conditions and 2) to explore the
potential for future cooperative research with BUSGS scientists. The
NASA ROV vehicle lacks on-board navigation - a significant
operational limitation. The vehicle, however, is small,
maneuverable, has excellent video resolution, and can be used from
small boats with 110 VAC (both 30 amp and 20 amp) circuits. Dual
forward-looking cameras with pan-and-tilt capability allow 3-D
viewing, an arguable plus for driving the vehicle but fun when using
the "virtual reality" helmet. The operator can select either forward-
looking or downward-looking images for tape recording. The 1000-
foot-long tether produced significant drag in currents and required
anchoring McARTHUR at each station; hence limiting our operational
depth to about 45 meters. In all, the ROV has potential given
appropriate project needs.


Our thanks to MARFAC for squeezing this operation into their very
busy April schedule. Amazing how they continually juggle, address,
and meet competing needs for personnel and equipment. Mobilizing
in San Francisco and demobilizing in Monterey made their work that
much more difficult. Larry Kooker and Walt Olson provided their
usual stellar service. Rob Kayen filled in for Jim Gardner at the last
minute - Jim owes Rob big-time! My thanks also to Mike Torresan,
Peter Dartnell, Fran Hostettler, Kaye Kinoshita, and Leda Beth Gray.
Thanks, Brian.
