Summary of Field Work: |
We are requesting to add 3 days to the scheduled Revelle/Jason cruise in 2020, Nooner and Chadwick are PIs. A new in-situ laser spectrometer under development now will be tested on a CTD rosette. Niskin water samples for calibration/verification of methane concentration and methane carbon isotope ratios will be collected. The primary test site is over known methane seep sites on Cascadia Margin. A secondary objective is to collect vent fluid samples at Axial Seamount during the geodetic dives that are the primary NSF project (Nooner/Chadwick). We will bring our Hydrothermal Fluid and Particle Sampler to mount on ROV Jason for vent fluid sampling. |
Summary of Facility Requirements: |
We require laboratory space on board for 5-6 scientists to set up the laser spectrometer, gas chromatography system, sampling equipment, and other laboratory equipment for water analysis. We require space on the ship's CTD rosette to mount the in-situ laser spectrometer, which will run on battery power and store data on board. We will use the ship's CTD rosette to collect Niskin water samples. |

Description of Repeating cruise requirements: |
Not applicable. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Nooner and Chadwick have a funded NSF cruise on Revelle with ROV Jason and AUV Sentry, leaving from Newport OR and working at Axial Seamount. This allows us to add days for testing a new instrument on Cascadia Margin methane seep sites near Newport. We also have a common interest in Axial Seamount and will work with Nooner and Chadwick to conduct time series vent fluid sampling during their operations, as we have done in previous years. We strongly prefer adding ship time to this cruise. The lab space on Revelle can accommodate our needs. As time permits, we would do CTD operations at Axial between ROV dives for more instrument testing opportunities. Butterfield is involved in another expedition on NOAA ship Ron Brown (West Coast Ocean Acidification, Feely/Alin chief scientists) currently scheduled for July 20 - August 8, ending in San Francisco. If the Nooner/Chadwick cruise departs Newport on Aug 14 or 15, this would provide enough time to transfer equipment from San Francisco. |

Explanation/justification for requested ports and dates of intermediate stops or to list additional port stops |
Revelle is currently scheduled to start and end the Chadwick/Nooner cruise in Newport OR. This is very close to our operations area, near a direct line to the Nooner/Chadwick ops area at Axial Seamount. |

Explanation of Science Party Requirements and Technician Requirements |
We have engineers responsible for the laser spectrometer and chemists responsible for water column and vent fluid sampling and analysis. We may also bring 1 or 2 students. |

Explain Instrumentation or Capability requirements that could affect choice of ship in scheduling. |
We will use the ship's multibeam system to image gas bubble plumes in the water column. We will use the ship's CTD to test a new instrument and collect water samples. We are collecting samples for stable carbon isotope analysis of dissolved methane. We prefer to have no work on board involving stable or radioisotopes of carbon without a clear plan for how to avoid contamination.

Explain Major Ancillary Facilities Requirements and list description and provider for "other" systems. |
Note that Nooner and Chadwick have requested ROV Jason and AUV Sentry for their work. We do not require those facilities for our primary project (testing in-situ spectrometer in water column). However, we will take advantage of the opportunity to collect vent fluid samples at Axial Seamount. |
