Summary of Field Work: |
Cruise will strongly resemble 2003-2008 cruises for US Global Ocean Carbon and Repeat Hydrography program. The I5 cruise will include ca. 193 full-depth CTD/rosette stations from the 200 meter isobath off South Africa to the 200 meter isobath off Australia. Stations are nominally 50 km (30 nmiles) apart, but are closer over steep bathymetry. At ca. 95 of the stations, there will also be a trace metal cast using a separate science-provided winch, cable, and rosette. Near noon each day there may be a hand-deployed optics profiler shallow cast. It is likely that Argo floats will be deployed at ca. 10-20 locations. |
|
Summary of Facility Requirements: |
Ship's facilities required are the same as for the I6S/2008 cruise on R/V Roger Revelle, and include dual CTD winches (w. cables, slip rings, etc.) in excellent condition for CTD casts up to 6000 meters with the science-team-provided large 36x10-liter rosette; A-frame and deck space for the science-team-provided trace metal winch, cable, and rosette; space for 3-4 science-team-provided lab vans convenient to the rosette room (typically on the fantail); space for 1-3 science-team-provided storage vans; underway seawater system with provision to add science-team-provided sensors to ship's sensor suite; underway meteorological sensor/data system; space to mount aerosol and other science-team-provided sampling gear; use of nearly all lab space; -80 freezer for storage of numerous small water samples; walk-in refrigerator for science storage; large amount of hazmat storage (at least as much in terms of volume as on past cruises); at least one laboratory with "tight" temperature specifications for salinometer and nutrients (specs can be provided); storage for ca. 20 Argo floats (these may have lithium batteries?), etc. |
|
Summary of other requirements and comments: |
Program will use nearly all science berths and most lab space. As with recent cruises (I8S, I9N, I6S), the program needs provision to run a propane line (from science-team-provided "barbeque" tank) to the helium sample lab, procedures to keep particulates (from barbecue, incinerator, smoking, paint chipping, stack, etc.) away from rosette room, avoidance of certain solvents, paints, and cleaning chemicals in specified labs (DOM/CDOM team: "if you can smell it we can detect it and so it may contaminate our samples"), avoidance of items using tritium (including some watches) anywhere near rosette room, "clean ship' regarding 14C and tritium (very low levels of these in seawater are sampled by the science team), and so forth as usual. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
This is approximately a repeat of WHP line I5. R/V Roger Revelle is ideal.
57 days at sea includes estimated transits to first station and from last station.
(Transits were based on Durban and Fremantle as ports. If Capetown is used on the west end, this would add about 750 nmiles of transit to the total track, or nearly 3 days to the already-long 57 days at sea. Note that Port Elizabeth saves about half the distance over Capetown. Since 57 days is likely already pushing it re duration, the issue of choice of ports vis-a-vis adjustments to the science plan should probably be discussed with NSF, the schedulers, and the ship operator.) |

Choice of ports is up to operator, within reason. See notes above regarding impact (3 more days of transit needed) of substituting Capetown, a more desirable port in some ways, for Durban, a less desirable port in some ways. |

Explanation of Science Party Requirements and Technician Requirements |
Jim Swift is the point of contact as of this time. If a different Chief Scientist is selected, UNOLS and the ship operator will be informed. The program is likely to use every science berth available. Both a resident technician and a computer technician are requested. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
Prefer dual shipboard ADCPs; GPS attitude sensor. There are numerous science operation requirements that relate to ship's installed instrumentation. These are the same as for past cruises for this program. For example, dual CTD winches, A-frame for trace metal casts, underway uncontaminated seawater, ship's science network, met sensors, etc. etc. are needed. R/V Roger Revelle is an example of a ship well equipped for this program's science operations. At this time we estimate that we will bring 3 lab vans and 2 storage vans. This may change.
