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.. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
This cruise will focus on the coastal Chukchi and Beaufort Seas and is a continuation of a 4 week Arctic cruise that took place in Sept 2016. The original cruise was to have been a 7 week cruise but due to complications with research and the timing of fall whaling we broke the cruise into two shorter cruises. After much discussion we received general approval from the Alaskan Eskimo Whaling Commission to operate in coastal waters in August with the understanding that we would be out of the Arctic by the first week in September and well south of Barrow by August 25. This was a hard fought compromise. |

Intermediate Port(s) |
Requested End Port |

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

Explanation of Science Party Requirements and Technician Requirements |
The proposed work requires six science party members. We also request the help of one technician to help with CTD deployment and recovery. |

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. We also require access to flow through uncontaminated seawater. The ship would also need to be able to operate in the Arctic Ocean.
