Summary of Field Work: |
We propose to carry out measurements of dissolved
gases, dissolved nutrients and dissolve/particulate carbon distributions in
of surface waters along the northern Bering and Eastern Chukchi shelves. This work will consist of a mixture of high-spatial survey of surface waters using the underway system of the research vessel and completion of hydrographic surveys across several shore-perpendicular transects using PI supplied towing/pumping vehicle.
The cruises will be scheduled during the late summer (Aug-Sep) and fall
(Sep-Oct) open water seasons of 2016. |
|
Summary of Facility Requirements: |
We will need to sample water from both the underway systems aboard ship and though a profiling/pumping insturment package that will be towed behind the ship along selected transects. We will need to mount PI-suppplied winch with hose for pumping water to the wet lab. We will also need access to sensor data from the surface underway system as well as on board ADCP and location data. Sampling of water from the underway and towed systems will be accomplished by connecting several PI-specific instruments to the water supply lines and coordinating sampling times with shipboard sensor
data. Space on the wet lab to set up benchtop instruments will be needed.
We also weill need to complete CTD casts at specific station and we will need a CTD/rosette and enough deck/lab space to collect, filter and handle water samples. Freezer and fridge space to store samples will be needed. |

Dates to Avoid: |
We would like to avoid early season dates, when sea ice is still present along the shelf/slope as well as later fall/early winter when sea ice formation starts. |

Repeating Cruise?

Yes |

# of Cruises: |

Description of Repeating cruise requirements: |
Our first cruise would be scheduled in late summer (late August - early September) of 2016 and then the second cruise along the same transect would be scheduled 2 to 3 weeks after completion (late September, early October) fo the same year. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Number of science days are based on our need to sample along the eastern Chukchi and Beaufort shelves and complete 4-6 shore-perpendicular transects.
We are requesting the Sikuliaq because the work is focused on high latitudes - Chukchi and Beaufort Seas. We do not expect to encounter sea ice during the late summer/fall period of our study, so other ships with comparable capabilities to operate in this region would also be appropriate.
Our cruise plan is flexible enough to accommodate additional science teams (which could require additional time) and oceanographic operations. We have identified several collaborators that may request ancillary and collaborative ship time in the near future. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
PI - supplied winch with pumping capabilities to use in conjunction with towed vehicle. Winch is typically mounted in main deck behind A-frame and controlled by PI supplied computers in dry lab.
One normal-sized container that houses towed vehicle supplies/equipment would be mounted on the back deck.
Bench-top mass spectrometer and semi-automated filtration system will need to be connected to the water lines from the underway system and towed vehicle. Bench-top nutrient/carbon analyzers will need to be set up in the lab space to analyze samples.
