Summary of Field Work: |
The overall objective of this project is to advance the understanding of mesoscale and submesoscale processes in a mid- and inner-shelf system, the hypothesized cross-shelf exchange mechanisms associated with them, and some of their biological impacts through direct measurements of the velocity and tracer fields, in a concerted effort with a larger research program called Inner Shelf Dynamics Departmental Research Initiative (Inner Shelf DRI), funded by the Office of Naval Research (ONR).
The field work will consist of a single cruise (approximately 8-16 days long, depending on final ship schedules) near Point Sal, off Central California (~35 N), during which high-resolution (~100 m horizontal resolution) and repeated underway measurements of velocity, temperature, salinity and fluorescence (at different wavelengths with the ALF system) will be made. Ideally, the field work will be scheduled to overlap with the Inner Shelf DRI activities, which are scheduled to take place in an approximately two month-long period (September-October/2017). |
|
Summary of Facility Requirements: |
All necessary equipment is external to the standard UNOLS instrument pool and will be provided by collaborating groups at no extra cost. We will utilize a side-mounted ADCP, a bow chain system instrumented with thermistors and CTD loggers (all provided by the Multiscale Ocean Dynamics group at SIO), an underway Advanced Laser Fluorometry (ALF) system (provided by Prof. Alexander Chekalyuk's group at LDEO or by the CCE-LTER group at SIO) and a towed underway T/S profiling instrument, which will be either a fast profiling CTD (provided by Jonathan Nash, OSU) or an equivalent instrument, provided by groups at SIO. |
|
Summary of other requirements and comments: |
The Ship Time Request will be made giving different scheduling options: 1) Any time slot on the R/V Sally Ride (within the September–October/2017 window) that may become available, 2) The October/14–22/2017 slot currently available on the R/V Sproul or 3) The September/07–23/2017 slot currently available on the R/V Sproul. All proposed slots (or others that may become available) are suitable to achieve the science objectives, and the longest available time slot (currently, option #3) is the optimal choice given the fact that the experiment design is based on obtaining reliable statistics with repeated spatial measurements. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The proposed time slots are:
1) Any time slot on the R/V Sally Ride (within the September–October/2017 window) that may become available (overlapping with the final Inner Shelf DRI schedule);
2) The October/14–22/2017 slot currently available on the R/V Sproul or
3) The September/07–23/2017 slot currently available on the R/V Sproul.
All proposed slots (or others that may become available) are suitable to achieve the science objectives, and the longest available time slot (currently, option #3) is the optimal choice, given the fact that the experiment design is based on obtaining reliable statistics with repeated spatial measurements.
The time period requested is chosen to overlap with the Inner Shelf DRI operations, when the moorings will already have been deployed and concurrent ship and small boat surveys will be underway. The combination of these simultaneous efforts would produce a unique and very powerful dataset for understanding coastal dynamics.
A local class ship (R/V Sproul) is sufficient, however the work can also be done on the R/V Sally Ride. |

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Having San Diego as the start and end port is preferred because the participants reside in the San Diego area and all currently scheduled cruises on the Sproul and the Sally Ride that surround the proposed cruise dates also start and end in San Diego. |

Explanation of Science Party Requirements and Technician Requirements |
2 Res Techs may be needed, because we plan to conduct 24 h underway operations. The party size of 14 (12 scientists + 2 Res Techs) is specified based on the R/V Sproul scientific berthing of 12. We expect 8 or 9 of the science party members to be graduate student volunteers. This approach has proved to be very successful in previous UC Ship Funds cruises. |
