Summary of Field Work: |
Exploring the seafloor and oceanic footprints of Escanaba Trough hydrothermal sulfide system.
This work will use ROV ops (and potentially AUV ops) to map and sample Escanaba Trough over approximately 20 days. We will perform hull mounted multi beam during transit to and from port (request, Newport, OR). The rest of the cruise will be devoted to joint ROV/AUV ops.
ROV ops will include grab sampling of rocks, high temperature fluid sampling, push coring, low temperature fluid sampling, sampling of organisms including corals, clams, and mussels; slurp sampling and integration with sensors (CTD, turbidity, O2, redox/ pH).
Cruise will ideally coincide with best weather window in the NE Pacific (summer). |
Summary of Facility Requirements: |
We will need a CTD and rosette for max water depth 3500 m; hull mounted multi beam bathymetry; sufficient deck space for joint ROV/AUV ops (requesting ROV Jason; requesting a Hugin AUV through NSERC) |

Description of Repeating cruise requirements: |
Not a repeating cruise |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We need a global class vessel to accommodate going ROV/ AUV ops. Please include Chris Beaverson (301-734-1013), our NOAA contact, on correspondance. |

Short Description of Op Area
for use in schedules: |
Escanaba Trough |
Description of Op Area: |
The area of work is Escanaba Trough, a spreading center at approximately 3350 m depth bounded by ridges approximately 1000 m higher. We are mainly interested in sampling the bathymetric highs within the trough. There is limited active hydrothermal venting occurring (one known location). |

None, |
Newport, OR, USA |
Explanation/justification for requested ports and dates of intermediate stops or to list additional port stops |
Newport, OR or other coastal OR port is closest. Additionally, we would like to cross the Cascadia Subduction Zone during transit in order to perform hull mounted multi beam for added project benefit. |

Explain Instrumentation or Capability requirements that could affect choice of ship in scheduling. |
DP is needed for Jason ops; Multibeam would be used during transit; "other operator provided inst" refers to Jason. Van refers to AUV van to Sentry van.
