Summary of Field Work: |
9-science day ROV-based cruise to (a) collect high-resolution video, acquire geochemical and biological samples, and sample authigenic carbonates, (b) acquire CTDs; (c) acquire hydroacoustic (water column) imagery and seafloor backscatter data between Cape Hatteras and Baltimore Canyon, at both shallow (upper slope, few hundred meter water depths) and deeper (up to 1400 m at Norfolk Canyon) methane seep sites |
|
Summary of Facility Requirements: |
Require DP, space for a van and ROV + ROV winch, appropriate A-frame, CTD capacity, basic wet lab: R/V Sharp meets all basic requirements based on discussions with marine superintendent and with the ROV operator (Oceaneering) |
|
Summary of other requirements and comments: |
USGS will supply hydroacoustic imaging equipment (EK80 and 38 kHz transducer--previously used on R/V Sharp in September 2015) and will lease a portable pole or retractable keel transducer pod mounted MBES system that will be operated by USGS technical staff and that will acquire swath water column imagery and seafloor backscatter on the upper slope only. USGS will likely supply the inertial navigation system for the MBES, but will discuss this with R/V Sharp technical staff. |

 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 |

Comments about foreign clearance requirements or
description of any other special permitting requirements
(e.g., MMPA, ESA, IHA, Marine Sanctuaries, etc.) |
Cruise does not include operations requiring IHA to comply with MMPA or OPR review for impact on marine mammals. Cruise entirely outside CZMA area and areas covered by Submerged Lands Act and entirely within the US EEZ. The USGS will complete standard NEPA documentation and approval for this activity according to application of its DOI Categorical Exclusion and rules outlined within the USGS NEPA Handbook. Ruppel handles many compliance activities for USGS Coastal and Marine operations and, based on her expertise with the various acoustic sources and other activities, the USGS has no concern about environmental concerns hindering the completion of this cruise. |
