Other ID: AT47

Status: Completed

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

Funding Program(s): Marine Geohazards Sources and Probability (LQ00ENR)

Principal Investigator(s): Jason Chaytor

Affiliate Investigator(s): Ying -Tsong Lin, WHOI

Information Specialist(s): Brian Andrews

Data Type(s): Imagery: Photo, Seismics: Sub Bottom Profiler, Sonar: Sidescan, Sonar: Multibeam

Scientific Purpose/Goals: Seafloor characterization of top of Atlantis II seamount.

Vehicle(s):

Start Port/Location: Woods Hole MA USA

End Port/Location: Woods Hole MA USA

Start Date: 2022-03-02

End Date: 2022-03-11

Equipment Used: CathX HD camera, Knudsen 3260, EM124 12 kHz multibeam, EM2040, Edgetech 2200M-subbottom, EdgeTech 2205

Information to be Derived: Multibeam depth and backscatter, subbottom profiles, and seafloor photographs from Hugin 6000 AUV.

Summary of Activity and Data Gathered: The original plan to survey the top of the Atlantis II Seamount was cancelled on 6 Mar because USBL communication "challenges" between Ocean Infinity's (contractor) Hugin AUV and the R/V Atlantis. Instead, it was decided to collect data in 2 areas of the continental shelf using the EM 124 multibeam, and Knudsen 3260 sub bottom sonars. Towards the end of the survey, two short AUV missions were conducted in shallow shelf waters without reliable USBL navigation as a demonstration.
