Summary of Field Work: |
Two expeditions are proposed, both to the Santa Barbara Basin, in contrasting seasons. Field work will include CTD casts as well as AUV and ROV operations. ROV operations will focus benthic flux measurements using a custom benthic chamber, as well as sediment push coring at the same locations. Sampling will be conducted along transects. AUV operations will include extensive photimaging surveys. Multi-coring capabilities are requested as a backup and supplement to ROV push coring. Extensive elevator use is anticipated to cycle the benthic chamber deployments. |
Summary of Facility Requirements: |
We are requesting use of ROV Jason and AUV Sentry for both cruises. We are also requesting use of a van for radioactive use of Sulfur-35 on both cruises. We require a working area maintained at 5 degrees C, to conduct incubations. An elevator is also requested to facilitate sample retrieval from Jason. |
Summary of other requirements and comments: |
We will be working in the Santa Barbara Basin in and around the shipping channel. We have had discussions with USCG sector command (LA/LB) and they have offered to help us with operation planning and notifications for our operations. Advanced coordination with the ship operator on this issue will be sought. As with previous cruises to the SBB, we expect fresh water to be an issue and will work with the Captain and Engineers to integrate water-making into our station planning. |

Optimum Start Date:

Dates to Avoid: |
We are targeting benthic conditions, that are controlled by seasonal factors, and the timing is important to the study. Late summer and early fall provide the best oceanographic conditions for basin deoxygenation. We also have an undergraduate component that is best matched to summer months. |

Description of Repeating cruise requirements: |
We seek a repeat cruise, but in Spring, 2020. See our second STR. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Ship Choice: We require a vessel that can handle ROV Jason and AUV Sentry operations, with space for a radioactivity van, CTD capability, and potentially multicoring. The Atlantis is an excellent platform for these studies. Similarly, the R/V Roger Revelle is also an appropriate platform. Smaller UNOLS vessels do not allow for sufficient science berthing, because ROV Jason and AUV take up ~15 science berths.
Dates: This is a seasonal study that targets benthic conditions. This is the Fall cruise, where we are targeting low oxygen conditions in the deep Santa Barbara Basin.
Number of days: We estimate 11 days of science operations, which we estimate to be sufficient for our in-situ measurement and sampling program as well as the intercalated AUV operations. We request 3 days of transit because we anticipate 2 days to and from the study site, and one day to leave the Santa Barbara Basin for a mid-cruise-water making session. |

Important Info on Foreign Research Clearances
|
|
Are you or any member in your science party bringing in any science equipment items which are regulated for export by the International Traffic in Arms Regulations (ITAR) and/or the Export Administration Regulations (EAR)?
|
No |
If yes, have you applied for the necessary permits through your export control office?
|
No |
Questions about ITAR/EAR regulations?
|
Comments about foreign clearance requirements or description of any other special permitting requirements (e.g., MMPA, ESA, IHA, Marine Sanctuaries, etc.) |
We will work in the Santa Barbara Channel, and may wish to sample within the Channel Islands National Marine Sanctuary. This decision will be made during the detailed cruise planning phase and through consultation with Sanctuary management team, located on the UCSB campus. |

Explanation/justification for requested ports and dates of intermediate stops or to list additional port stops |
As per previous cruises in this area, we may opt for a mid-cruise transfer of personnel and samples.
We would also like to explore the option of using a port in the Los Angeles area, specifically the AltSea port. |

Explanation of Science Party Requirements and Technician Requirements |
We plan 24 hour operations that include CTD casts, as well as ROV and AUV operations, and will need round-the-clock technician support. |

Explain Instrumentation or Capability requirements that could affect choice of ship in scheduling. |
We plan to use sulfur 35 to conduct sulfate reduction rate measurements in push cores collected by ROV. We require a van with space to conduct incubations at ~5 degrees C.

Explain Major Ancillary Facilities Requirements and list description and provider for "other" systems. |
We may not need the cold lab van, depending on the adequacy of the ship's environmental rooms. |
