Field Activity Details for field activity 2018-002-FA

Other ID: none

Status: Pending

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s): USGS GAS HYDRATES (LQ000FP)

Contact(s): Carolyn Ruppel

Information Specialist(s): Carolyn Ruppel

Data Type(s): Sonar: Single Beam, Seismics: Sonobuoy, Seismics: Air Gun / Water Gun

Scientific Purpose/Goals: Acquire 1750-2000 line-km of MCS data with 210 in^3 GI-guns and sonobuoys (for long offsets) in the data gap for modern seismics between Hudson Canyon and Currituck slide


Start Port/Location: Lewes, DE

End Port/Location: Lewes, DE

Start Date: 2018-08-06

End Date: 2018-08-24

Equipment Used: Other, SIMRAD EK60

Information to be Derived: deep basin structure, geohazards (slope failures), gas hydrate distribution

Summary of Activity and Data Gathered:

Notes: Nathan Miller co PI; will need 2 gun techs from PCMSC (have already contacted them)

Project needs 210 in^3 guns, 1 km streamer and UNOLS approved winch, and several pallets of sonobuoys

R/V Sharp has not yet chosen the dates on the basis of the STR filed in early July 2017, but the project will likely be at sea a bit over 2 weeks in July 2018, pending completion of the BOEM IAA

Project will require an IHA and a biological opinion from OPR, to be handled by Ruppel with the regulator


Mid-Atlantic margin, Hudson Canyon to Currituck Slide, outer shelf to 3000 m water depth
