Summary of Field Work: |
Cruises will be undertaken to measure hydrography, nutrient concentrations, rates of nitrogen and carbon uptake and fixation, molecular characterization, and other dissolved and particulate constituents. Investigators will be deploying CTD rosettes to make measurements and will collect water samples that will require deckboard incubators (some of which they will bring themselves) for conducting incubation experiments. |
|
Summary of Facility Requirements: |
We require a ship that can operate in Arctic coastal and oceanic waters that is
capable of deploying CTD-rosettes and has ample deckspace and flowing
seawater to facilitate incubation experiments. We require laboratory space for
processing samples indoors. We require wet and dry lab space. Stable isotopes (15N and 13C) will be used in incubation studies and will require lab space separate from where natural abundance samples are taken.. |

|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We are requesting time on the R/V Sikuliaq but any ship of opportunity (i.e. the R/V Healy) that has sufficient laboratory and deck space for a flow through system to incubate samples would be acceptable. Four berths are requested in each year. Since we do not require large amounts of deck space or number of berths for this project, we anticipate working with the PIs of other funded projects to optimize ship resources. |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
Seward, AK, USA |
None |
Barrow, AK, USA |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Prefer Seward to Barrow ports but could Barrow to Seward, Barrow to Barrow, or Seward to Seward as long as we have sample time in the coastal and offshore regions of the Chukchi and Beaufort Seas. We would need to add transit days if the ports were Seward to Seward or Barrow to Barrow. We plan to sample en route between Seward and Barrow. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We would require a CTD, the ability to set up flow through incubations on the deck 4 degree C, -20 degree C and - 80 degree C sample storage. The ship would also need to be able to operate in the Arctic Ocean.
