FILING DATE: 23 October 2003
CONTRACT/GRANT NUMBER: NSF Grant OCE-0000733.
PRINCIPAL INVESTIGATORS: Adriana Huyer, Robert L. Smith,
P. Michael Kosro, P. A. Wheeler, Jack A. Barth, W. T. Peterson, E. Sherr and B. Sherr
PURPOSE: To determine physical, plankton and nutrient/chemical conditions over the continental
margin for climate change studies in NE Pacific. In particular, to make CTD and CTD/rosette and net
tow stations along 5 lines (off Newport, Heceta Head, Coos Bay, OR. and Crescent City, CA.), to
deploy drifters at selected locations on the Newport line, and to make continuous observations of
currents using ADCP and of surface-layer temperature, salinity and fluorescence by means of ship’s
thru-flo system. Figure 1 shows the location of the CTD stations. Table 1 shows the CTD station
positions, and Table 2 shows the biochemical sampling depths.
SAMPLING PLAN:
1. Use ship’s intake continuously for Temperature, Salinity, and Fluorescence
2. Continuous ADCP Profiling (150 kHz transducer) for water velocity and backscattering for bioacoustics.
3. Standard CTD Stations using SBE 9/11 plus CTD system for Temperature, Salinity, Fluorescence,
Light Transmission, Oxygen, PAR.
4. Rosette sampling: 5 liter bottles for nutrients, chlorophyll, microzooplankton
5. Deploy surface drifters at selected NH-line stations.
6. Vertical net tows: 1/2 meter nets 100 m to surface; Horizontal net tows with 1 m2 MOCNESS.
CRUISE NARRATIVE
A brief overview of W0309B is presented here. An event log is provided in Table 3, and
participating personnel are listed in Table 4. Wecoma departed Newport at 1000 PST on 26 September 2003. CTD sampling started at NH-1 and continued out to NH-85. A single vertical net tow was
done at NH-1, and both MOCNESS and vertical net tows were started at NH-5. In order to maximize
darkness for the MOCNESS tows, the CTD stations were done in their usual order out to NH-25,
then the ship returned to NH-15 to do a CTD, then MOCNESS tows at NH-15 and NH-25. CTD
stations and net tows were then done in order from NH-35 out to NH-85, finishing sampling on the
line at 1238 PST on 27 September. Drifters were released at NH-10, 15, 25, 45 and 65. The ship
transited to the inshore end of the Crescent City line in order to be at the inshore end in daylight, and
began sampling at CR-1 at 0621 PST, 28 September, with MOCNESS tows beginning at CR-2. The
CR line was finished at 0315 PDT, 29 September, and the ship transited to the inshore end of the
Five Mile line.
1
The ship arrived at FM-1 at 1157 PST on 29 September. Working offshore, the Five Mile line
was finished at 2110 PST on 29 September with no MOCNESS tows done on this line.
The ship arrived at the inshore end of the Heceta Head line at 0231 PST on 30 September,
and CTD stations along with MOCNESS tows at HH-2, HH-3, HH-4 and HH-5, were completed out
to HH-9 at 1902 PST 30 September. The ship then returned to HH-5 and at 2147 PST on 30 September, began a series of three deep MOCNESS tows, which were completed at 1145 PST on 1 October.
The ship then transited to Newport, arriving at the pier at 1555 PDT, 1 October.

Preliminary Results, W0309B
During the week before the cruise, winds had been generally favorable for coastal upwelling,
except for a 24-hour period on 24-25 September when the wind was blowing weakly from the south.
Moderately strong winds from the north resumed just before the beginning of our cruise, but were
soon replaced with generally weak winds.
Four sections were sampled: the NH, CR, FM, and HH lines. Mocness sampling on the FM line
and all sampling on the RR-line was omitted to allow time for a series of four deep MOCNESS casts
at HH-5 at the request of W. T. Peterson and his zooplankton sampling team.
All four of the hydrographic sections showed the effects of persistent seasonal upwelling: isopleths of temperature, salinity, density and dissolved oxygen all bend upward from depths of 50-150
m at the offshore end of the section to intersect the surface. Off Newport, the coastal upwelling front
is strong and narrow, and the 33.0 isohaline and 25.0 isopycnal intersect the sea surface near the midshelf. Off Coos Bay, this intersection lies over the outer shelf, and off Crescent City it lies >20 km
beyond the shelf-break.
Downwarping of deeper isopycnals (>26.5 kg/m3) toward the continental margin suggests the
presence of poleward flow over the upper slope, and this is confirmed (?? CHECK) by current
measurements from the ship-borne ADCP.
On all sections, the permanent halocline is still cool compared to data from 1999 and 2001.
T-S diagrams suggest subduction of warm, high-salinity inshore surface water on the CR-line.
Inshore waters were surprisingly clear; chlorophyll and fluorescence values were much lower than
they had been in July 2003.
The attached zooplankton report was provided by Dr. Wm. Peterson, and the attached
microzoonplankton report was provided by Drs. Evelyn and Barry Sherr.

Other zooplankton sampling:
Vertical Plankton Tows (VPTs – 0.5 m diameter, 200 um mesh) were completed at
stations NH-1, 5, 10, 15, 20, 25, 35, 45, and 65, CR-1, 2, 3, 4, 6, 7, 9a, and 11, FM-1, 3,
4, 5, 7, 8, and 9, HH-1, 2, 3, 4, and 5.
The final four MOCNESS tows were plunged to depths greater than 900 meters in an
effort to quantify chaetognath vertical distributions for visiting scientist Travis Johnson.
No live euphausiids experiments were conducted during this cruise.
