2.01 CTD
At a minimum, 1,000-meter CTD casts shall be conducted at each mooring site between 08°N and 08°S for sensor inter‑comparison purposes. As time permits, additional or deeper CTD’s should be conducted whenever addition of the CTD’s will not impact scheduled mooring work. For example, if the ship would arrive at the next mooring site in the middle of the night, it is preferable to do CTD’s on the way, rather than remain hove to waiting for daylight. Another example would be when mooring operations are significantly ahead of schedule. Beyond those at mooring sites, CTD’s should be conducted in the following order of priority:
· 1,000-meter CTD’s at one degree latitude intervals between 12°N and 08°S, along the ship’s trackline.
· Extend 1,000-meter CTD’s at mooring sites to a minimum of 3,000 meters or a maximum depth of 200 meters from bottom. Four to six deep casts are optimal, occurring at the beginning and end of the cruise as well as at both equatorial sites.
· 1,000-meter CTD’s every one‑half degree of latitude between 03°N and 03°S.
· Additional calibration CTD’s to be determined by Chief Scientist.
2.02 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. Ten AOML drifters are scheduled at the following positions:
4N,2N,0,2S 165E
As close as you can get to:
0 170W
4S 180
4S 165E
4S 155W
5S 180
8S 170W

2.03 Pacific Marine Environmental Laboratory (PMEL) Argo Profiling CTD Floats
One Argo float is scheduled for deployment on this cruise. Individual deployment positions can be shifted by a degree or so along the ship track if more convenient. Each float weighs about 56-lbs. Boxes are numbered sequentially in order of deployment. The boxes weigh about 200-lbs full and are 82” long x 17” high x 23” long. Boxes cannot be stored or transported on their small ends. The floats are sensitive to high temperatures, so as space for a pair of floats becomes available on the computer lab rack, it will be desirable to move floats from the next box to the rack at the earliest convenient time. A manual for float-testing and deployment has been sent to the ship. Float deployment locations are as follows:
8N, 165E
5S, 180
8S, 170W
8S, 155W
Argo float questions should be directed to:

2.04 Discrete Gas Sampler
Whole air samples are cryogenically dried and pumped into glass flasks by an automated system in the computer lab. Following the cruise, the flasks are returned to Princeton University for analysis by prepaid FEDEX. Pairs of flasks are collected while the ship is underway at 8N, 4N, 0, 4S and 8S along the 155ºW and 170ºW lines. Automated sampling cycle is approximately 5 hours. It is anticipated that the Survey Technician will perform the maintenance tasks.

2.05 Dissolved Inorganic Carbon Analysis (DIC)
A 0.5-liter seawater sample from surface CTD casts will be taken and stored for later dissolved inorganic carbon analysis. Sample jars and mercury chloride solution will be provided by Scripps institute of Oceanography. It is anticipated that the survey technician, together with MBARI personnel will take the samples. A small bench-top drill press is installed on the ship to assist with the bottle capping process. Samples will be shipped to Scripps at the conclusion of GP8 in Honolulu.

2.06 Nitrate N and Oxygen Isotope Analysis
At 7°N 165°E, 1°N 165°E, 7°S 165°E and 7°S 180°, 1°N 180°, 7°N 180°, a 50-ml seawater sample will be taken at the following depth from the CTD casts: Surface, 10 m, 20 m, 40 m, 60 m, 100 m, 150 m, 200 m, 400 m, 600 m, 800 m, 1000 m. Each sample will be stored for later Nitrate N and Oxygen isotope analysis. Sample jars will be provided by Scripps Institute of Oceanography. It is anticipated that the Survey Technician, together with other embarked scientific personnel will take the samples. Samples will be frozen in the scientific freezer and will be collected at the conclusion of GP8 in Honolulu.

3.0 HAZARDOUS MATERIALS
NOAA Ship KA’IMIMOANA will operate in full compliance with all environmental compliance requirements imposed by NOAA. The Chief Scientist shall be responsible for complying with MOCDOC 15, Fleet Environmental Compliance #07, Hazardous Material and Hazardous Waste Management Requirements for Visiting Scientists, released July 2002. The MOCDOC web site address is:
By Federal regulations and NOAA Marine and Aviation Operations policy, the ship may not sail without a complete inventory of all hazardous materials by name and the anticipated quantity brought aboard, MSDS and appropriate neutralizing agents, buffers, and/or absorbents in amounts adequate to address spills of a size equal to the amount of chemicals brought aboard and a chemical hygiene plan. The Chief Scientist shall account for the amount of hazardous material arriving and leaving the vessel. NOAA Ship KA’IMIMOANA Environmental Compliance Officer will work with the Chief Scientist to ensure that this management policy is properly executed, and that any problems are brought promptly to the attention of the Commanding Officer.
3.1 Material Safety Data Sheet (MSDS)
All hazardous materials require a Material Safety Data Sheet (MSDS). Copies of all MSDS’s shall be forwarded to the ship at least two weeks prior to sailing. The Chief Scientist shall have copies of each MSDS available when the hazardous materials are loaded aboard. Hazardous material for which the MSDS is not provided will not be loaded aboard.
3.2 HAZMAT Inventory
The Chief Scientist will complete a local inventory form, provided by the Commanding Officer, indicating the amount of each material brought onboard, and for which the Chief Scientist is responsible. This inventory shall be updated at departure, accounting for the amount of material being removed, as well as the amount consumed in science operations and the amount being removed in the form of waste.
3.3 HAZMAT Locker
The ship’s dedicated HAZMAT Locker contains two 45-gallon capacity flammable cabinets and one 22-gallon capacity flammable cabinet, plus some available storage on the deck. Unless there are dedicated storage lockers (meeting OSHA/NFPA standards) in each van, all HAZMAT, except small amounts for ready use, must be stored in the HAZMAT Locker.
3.4 HAZMAT Spill Response
The scientific party, under the supervision of the Chief Scientist, shall be prepared to respond fully to emergencies involving spills of any mission HAZMAT. This includes providing properly-trained personnel for response, as well as the necessary neutralizing chemicals and clean-up materials. Ship’s personnel are not first responders and will act in a support role only, in the event of a spill.
3.5 Responsibilities
The Chief Scientist is directly responsible for the proper handling, both administrative and physical, of all scientific party hazardous wastes. No liquid wastes shall be introduced into the ship’s drainage system. No solid waste material shall be placed in the ship’s garbage. Ancillary Projects shall properly train their personnel in hazardous material handling and disposal.
3.6 Ancillary Projects Hazardous Materials
1. Mercuric Chloride solution 400 ml Scripps/PMEL
2. Mercuric Chloride powder 30 g Scripps/PMEL
3. CO2 cylinder 2-AL30 PMEL
