2.0 OPERATIONS



Mooring Operations are scheduled to be conducted as shown in Appendix A. Operations will be conducted from 8N - 125W to 8S - 125W, a short stop in Marquises to exchange scientific personnel and thence to 5S - 140W to 9N -140W. The following mooring operations are anticipated, though the work may be changed by direction of the Chief Scientist, in consultation with the Commanding Officer.

2.2 Bloomsburg University Barnacle Census



Barnacles will be collected in accordance with TAO Standard Operating Instructions. A pre and post cruise inventory of Hazardous Materials (Hazmat) brought aboard and offloaded from the ship will be given to the Chief Scientist and Commanding Officer. All Hazardous Materials will be properly labeled as to content, Hazmat classification and cruise number.





2.3 Monterey Bay Aquarium Research Institute (MBARI) Underway Mapping



2.3.1 Underway Mapping

The MBARI underway-mapping system (temperature and fluorescence) will be on-line and running throughout this cruise. Phytoplankton work consisting of chlorophyll and nutrients extractions will extracted from CTD water samples at 0, 10, 25, 40, 60, 100, 150 and 200m. The total volume used from each bottle, including rinses is approximately one liter; except for the surface bottle, which will require approximately three liters. This requires use of the sink/bench area of the wet lab.





2.4 Atlantic Oceanographic and Meteorological Laboratory (AOML) Surface Drifters



The Global Drifter Center at NOAA/AOML requests drifter deployments on an ancillary basis. The drifters are small, easily deployed devices which are tracked by Argos and provide Sea Surface Temperature (SST) and mixed layer currents. The global array of drifters provides SST ground truth for NOAA's polar orbiting satellite AVHRR SST maps. They also provide data to operational meteorological and ocean models, and research ocean current data sets.



Most often, drifter deployments are requested when crossing 00 30.0N, the Equator, and 00 30.0S. Drifter deployments are frequently requested at other locations along the cruise track. Typically, less than 12 deployments are requested on a cruise. The deployments should have little or no impact upon primary ship operations. Questions should be directed to:

2.5 Fluorometer (Behrenfeld)



2.5.1 Fast Repetition Rate Fluorometer



Core measurements will be sampled with a bench-top fast repetition rate fluorometer (FRR). The FRR will be setup to run continuously on a flow through of clean uncontaminated sea water (requires 20mL per minute). Preferred (but not required) FRR set-up locale is near the wet-lab sink for disposal of the measured seawater.



2.5.2 Single-cell-FRR

Discrete samples will collected with a Niskin bottle at CTD stations and from the flow through system through our the cruise.



2.5.3 Solar Irradiance

A Licor Data Logger (LDL) will be used to simultaneously log daily changes in solar irradiance. After consultation with the Field Operations Officer the solar sensor will be mounted in an acceptable exterior location free of shading. The LDL recorder will be enclosed from the weather, while the sensor itself is water resistant and will be exposed to the elements.



Continuously logging of the following six second averaged data, throughout the cruise provided to the FRR laptop computer:



2.6 Trace Metal Nutrient Analysis - Towed Fish (Metzger)



2.6.1 Macro- and Micro-Nutrients Analysis



Macro- and micro-nutrients analysis will be measured through a portable clean bench installed in the wet lab. A towed fish will be used to collect continuous water samples when making way. As time permits the towed fish will be deployed post mooring operations and recovered prior to mooring operations. This ultra clean method of sampling seawater will be used for trace metal analysis. This fish shall be towed away from the ship's wake via either the CTD J-frame, the starboard aft crane or via a temporary boom rigged off the starboard quarter. The crane or boom setup should be stabilized laterally by fore and aft guy lines as needed. Final rigging will be determined during the 15-23 August Honolulu inport after consultation with Commanding Officer and/or his shipboard designate. Collected sample water is pumped through clean tubing into the wet lab for analysis. Prior to mooring stations the towed fish will be brought aboard and secured.



Seawater flow rate is 4 liters/min, the pump will require a quick release type connection to and continuous use of ship's compressed air (2-3 SCPM at 80psi.) while the unit is sampling.



The fish consists of the 3/8" Kevlar strength member with a 1/2" OD polyethylene tubing (with a thin Teflon liner) in parallel. The Kevlar and poly tubing are joined every 1.5 feet by cable ties and tape. The paired line runs through the sheave on the crane or j-frame. At the end of the tube is a plastic torpedo shaped fish through which the plastic tube terminates, with the tube opening at the nose of the torpedo. The Kevlar passes through the middle of the torpedo, similar to the axis of a weathervane, and is shackled to the fiberglass "bat-wing" depressor about 1 meter below the torpedo. The internally weighted depressor (40 lbs.) keeps the line tight, pulling the fish down into the water to decrease the towing angle. The torpedo typically rides about 1-2m under the water surface. At 9 knots the horizontal towing force

is approximately 1000 lbs., with momentary increases to 2000 lbs in high sea state.



2.6.2 Enrichment Experiments



In addition samples of the collected seawater will also be stored in four six-liter carboys for enrichment experiments, which involve a 20-hour incubation period in a darkened water bath (wet lab).





3.0 Hazardous Materials



The Chief Scientist is responsible for the proper and safe storage of scientific hazardous material and complying with NC Instruction 6280B, Hazardous Materials and Hazardous Waste Policy, Guidance, and Training, dated May 8, 1991. This includes the requirement for the Chief Scientist to remove all scientific team hazardous materials and waste at the end of the cruise.
