Ocean Floor Geophysics (OFG), in cooperation with Fukada Salvage and Marine Works (Fukada), has completed another high resolution CSEM survey of near surface gas hydrates.
The survey was executed using the Scripps Institution of Oceanography Vulcan system for the National Institute of Advanced Industrial Science and Technology (AIST) in Japanese waters.
Following the successful 3D CSEM survey and inversion models completed in 2014, the 2015 survey comprises over 670 line kilometers of high resolution data collected from the Fukada vessel Shin Nichi Maru.
A 3D inversion of the EM data for an area of interest for this year’s survey has been completed.
The contract for the 3D inversion of the data for the entire 2015 survey area has also been awarded to OFG and will be completed in November this year.
Fukada Salvage and Marine Works acted as prime contractor to AIST.
