FILING DATE: 16 December 2002
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, the Rogue River, OR. and Crescent
City, CA.), to make continuous bio-acoustic observations between the 50-500m. isobaths along the 5
lines, 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.
7. Continuous bio-acoustic observations between the 50-500m isobath along 5 sections using a
Hydroacoustics Technology, Inc., system towed alongside the ship.
CRUISE NARRATIVE
A brief overview of AT721 is presented here. An event log is provided in Table 3, and participating personnel are listed in Table 4. The R/V Atlantis departed Newport at 1510 PDT on 27 September 2002. CTD sampling started at NH-3 and continued out to NH-85. NH-1 was skipped to save
time since both the ship’s crew and the science party needed to learn the sampling procedures on the
Atlantis. The HTI (bio-acoustic system) was deployed at NH-3, and both MOCNESS and vertical net
tows were started at NH-5. Drifters were released at NH-10, 15, 25, 45 and 65. At NH-85, a shallow
CTD cast was done prior to the usual cast to 1005 m., in order to collect surface water. The ship
transited to the offshore end of the Crescent City line, since this line had the second highest sampling
priority, and began sampling at CR-11 at 2157 PDT, 29 September. After the CTD and a vertical net
1
tow at CR-6, the ship transited to CR-1, so the inshore stations could be done in daylight. Following
the CTD and vertical net tow at CR-1, the HTI was deployed. The CR line was worked out doing
CTDs and net tows, ending with just a MOCNESS tow at CR-6, after which the HTI was recovered.
The CR line was finished at 0505 PST, 1 October, and the ship transited to the inshore end of the
Five Mile line. The Rogue River line was not sampled since the line had the lowest priority for
sampling, and there was not sufficient time to do it.
The ship arrived at FM-1 at 1226 PDT, and worked out doing CTDs and net tows, completing
FM-9 at 0306 PDT, 2 October. The HTI was deployed at FM-1 and recovered at FM-7. After transiting to the Heceta Head line, sampling began at HH-1 at 0850 PDT on 2 October, doing CTD’s and
net tows while working offshore. Following the CTD and vertical net tow at HH-2, the HTI was
deployed, and MOCNESS tows were started. The HH line was finished at 0212 PDT on 3 October,
and headed for Newport; arriving at the pier at 1130 PDT.

Other zooplankton sampling:
Vertical tows (0.5m diameter, 200µm mesh) from 100 meters (or from just above bottom)
to surface were completed at stations NH5,10,15,25,35,45, and 65; CR1,2,3,4,6,7,9,and
11; FM1,3,4,5,7,8,and 9; HH1,2,3,4 and 5. Replicates for EtOH preservation were taken
at FM8, FM9, and CR7.
Euphausiids from station CR3, CR4, and HH3 were incubated for molting rate
experiments.
