Summary of Field Work: |
We propose two research cruises in 2017 and 2018 that will depart and return to Puntarenas, Costa Rica. The first site is within a 12-hour steam from port. We plan 4-6 days of work at each of 3 strategically selected sites on subducting seamounts, plus additional time for oceanographic and bathymetry surveys, for a total of approximately 20 days at sea per cruise. We will utilize either the Jason ROV or a combination of the Alvin HOV and the Sentry AUV to complete the benthic surveys and sampling. This will be augmented through the use of the user-supplied Wire Flyer water-column sampler to provide a 3-dimensional view of these habitats. The Wire Flyer is a ship-towed (at 3-4 knots) autonomous vehicle that slides up and down a standard 0.322 cable in a controlled manner (Roman and Hebert, 2011) |
|
Summary of Facility Requirements: |
We will need an ROV or HOV/AUV combination, ship with dynamic positioning, 0.322 wire for the Wire Flyer, CTD/rosette, ship-board multibeam, cold room facilities, and -80 ultracold freezer. |

Optimum Start Date:

5/15/2018 |
Dates to Avoid: |
There are two cruises requested, and ideally this cruise should be exactly one year after the previous cruise [now scheduled for May 2017]. It should also start early enough to provide ample time for sample processing and analysis before the end of the project in September 2019. |

Description of Repeating cruise requirements: |
None |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Alvin / Sentry is preferred. Alvin alone will not suffice, as we plan a number of near-seafloor surveys that would require Sentry. The alternative to this combination is the ROV Jason. If Jason, we do not have a preference for the support ship. Cordes currently has a conflict with a cruise that is scheduled for 9/20/17 - 10/22/17. |

Explanation of Science Party Requirements and Technician Requirements |
Numbers are approximate. We will require the necessary personnel to run Alvin + Sentry or 24-hour ops on Jason. We will fill the rest of the available bunks with scientists. |

The Wire Flyer is a ship-towed (at 3-4 knots) autonomous vehicle that slides up and down a standard 0.322 cable in a controlled manner (Roman and Hebert, 2011). Using the lift force created by wing foils, the vehicle can achieve controlled up and down profiling velocities (0- 2.25 m/sec) within a specified depth band down to ~900 m depth. The high repetition rate of the Wire Flyer provides a far more complete data set than would be possible with repeat ship board CTD casts. While being towed, updated commands and condensed data samples can be sent to and from the Wire Flyer via an acoustic modem to refine the sampling speed and depths to ensure proper coverage. The vehicle typically creates high horizontal resolution (T, S, O2, Chl, CDOM, turb) sections. For this project a Satlantic Deep SeaFET pH sensor will be integrated along with the SBE 49 FastCAT, Aanderaa 4831f O2 sensor and Wetlabs triple Ecopuck. These sensors will also be available to be used on the submersibles.
