Summary of Field Work: |
Two cruises to the high latitude Pacific Ocean (Hawaii to Hawaii, Hawaii to San Diego) to measure the abundance and diversity of Prochlorococcus along meridional transects focusing on gradients in temperature. Collaborators will measure trace metals and other biological variables. Cruises will not enter foreign waters.
This project is a formal collaboration between Johnson (Duke), Erik Zinser (UTK), Steven Wilhelm (UTK) with additional collaborators at U Hawaii, U Otago and USC. |
|
Summary of Facility Requirements: |
For a successful project we require full use of the ships available facilities including: CTD, ADCP, flow through sea water (for on-deck incubators), compressed air, full complement of bunks available to scientists, radioisotope van (with hook-ups), uncontaminated seawater for in laboratory analyses, MET data, 'live' internet (as available) for public outreach. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We are requesting the R/V Revelle or Melville (or similar class) because of its higher berth capacity (we expect a full ship with out collaborators) and because the cruise track is from Honolulu to San Diego (its home port).
The number of days is the minimum to complete the transect from Honolulu, HI to San Diego and includes a northern component that involves a 'Z' transect around the 15C surface temperature region. The transect would track the 18C surface isotherm to San Diego. We also require some days to be on station along the transect. 28 days is the lowest number that allows us to accomplish this project's goals.
3.5 mobilization days are requested: 2 on the front end to set up equipment and 1.5 on the arrival end to unload equipment and samples. These requests are based on our past experience of the time it takes to set up our incubators and equipment on UNOLS ships. |

Short Description of Op Area
for use in schedules: |
N Pacific |
| Description of Op Area: |
The cruise will start in Honolulu and end in San Diego. Initially we will go north, create a Z pattern and then track the 18C isotherm. The final track will be determined by the current sea surface temperature patterns. The following coordinates provide a projected track:
21.3 -157.8
35.6 -157.8
48 -157.8
32.6 -148
48.1 -148
42 -145
43.5 -140

41 -130
34 -125

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
The goals of this cruise are to measure cyanobacteria diversity and activity in the context of temperature variability along meridional transect (with extreme temperature gradients) in the Pacific Ocean. The two ports that accomplish this goal while minimizing the number of days at sea are starting at Honolulu and ending San Diego. If it is logistically more desirable for UNOLS, we are open to ending the cruise in Seattle but would require modification to the number of requested science days. We are also open to returning to Honolulu, but this would add a significant number of days to the cruise request (and increase our shipping costs on demob). Finally, we are open to a round trip voyage from San Diego, but this would require an additional 5 science days to accomplish the same goals. |
