Summary of Field Work: |
Characterization of the biological and chemical features of the transition zone between the North Pacific subtropical gyre and the North Pacific subpolar gyre. The cruise entails a transect to and from Hawaii to approximately 47 degrees North (into the iron-limited region) along 158 degrees west. A series of underway instruments that tap into the seawater intake system will be used to define the exact location of sampling stations. Approximately 5 stations will be occupied for 24 hrs with depth profiles of the upper water column (approximately 1000m). |
|
Summary of Facility Requirements: |
We will need a CTD/rosette, radioisotope van, trace metal van and trace metal clean CTD/rosette/line, flow cytometer van, ability to tow a trace metal clean pump while underway, sufficient deck space of on-deck flowing seawater incubators, underway CTD, A frame for deploying radiometer, and sufficient flow of the seawater intake to run multiple instruments simultaneously. |

|
|
Optimum Start Date:
|
5/27/2017 |
Dates to Avoid: |
We are currently scheduled for May 27-June 13. Going much later than this would mean that we have to transit further north to reach the transition zone. As chief scientist, I could delay the cruise by no more than 1 week. |

Description of Repeating cruise requirements: |
This does not consist of a repeating cruise in one year |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We are currently scheduled for the Kilo Moana from May 27-June 13, with mob on May 26 and demob June 14, departing from and returning to Hawaii. The ship time and science has already been funded by the Simons Foundation. This is the second funded cruise by the Simons Foundation to the same location. The first cruise in 2016 was originally scheduled for the R/V Thompson and because of engine problems had to be transferred to the KOK. The KOK will not be acceptable for this 2017 cruise.
The currently funded 2017 cruise has a science party of 26 (a full ship), representing 12 principle investigators. The requested number of days is required to transit from the subtropical gyre through the transition zone to the southern most edge of the subpolar gyre. The location of the transition zone migrates north through the summer and thus delays in the timing of the start of the cruise mean that we will have to transit further north. This would greatly impact the science that could be done. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
Require use of 14C and 3H isotopes for productivity measures so require radioisotope van. Will conduct trace metal measurements so require trace metal clean winch/cable and trace metal clean van. Will also deploy an underway towed trace metal pump that pumps water to the van. May require a third van for a flow cytometer. Require a CTD/Rosette for depth profiles to ~1000m. Will bring from UW, an underway CTD to be launched while underway from a mounted position from the stern. Require use of an A frame to deploy a radiometer.
