Summary of Field Work: |
13-day cruise on US Atlantic Margin upper continental slope methane seeps between Cape Hatteras and Wilmington Canyons. Approximate area of operations from shelf break to 1200 m water depth. We will conduct CTDs along a maximum of 5 transects down the upper slope and will do intensive surveying of the seafloor and water column (for methane plumes) from the shelf-break to the upper slope. The surveys will include a user-provided (USGS) multibeam with water column imaging capabilities, a user-provided (USGS) EK80 with 38 kHz transducer (used on the Sharp in September 2015), and real-time measurements of greenhouse gas concentrations in near-surface waters (requires a user-provided --Rochester--dedicated pump system). |
Summary of Facility Requirements: |
Standard navigation and met parameters, ADCP, CTD, 2 free pods in the retractable keel, various reefer/freezer, possible occasional Knudsen use (USGS technical staff can handle) |
Summary of other requirements and comments: |
Rochester provided equipment to be deployed: high-rate seawater pump mounted in transducer well or over the side (USGS operational personnel will assist with configuring)
USGS will provide a portable MBES system with water column imaging capabilities and an inertial navigation system (unless the R/V Sharp's Reson inertial nav is available to be used), the EK80 and 38 kHz transducer, internal network and data storage |

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.) |
No foreign clearance. Cruise is entirely outside of area covered by CZMA or Submerged Lands Act and within US EEZ. No seismic sources and no need for IHA or OPR consultation. USGS will complete NEPA requirements and DOE will approve NEPA prior to cruise. |
