Ocean Floor Geophysics Ltd. (OFG), in cooperation with Fukada Salvage and Marine Works Co. Ltd. (Fukada), has completed another high-resolution controlled source electromagnetics survey of near surface gas hydrates in Japanese waters, according to a news release.

For the survey, Ocean Floor Geophysics said it used the Scripps Institution of Oceanography Vulcan system. The survey, which was conducted for the National Institute of Advanced Industrial Science and Technology, comprised more than 670 line km of high resolution data collected from the Fukada vessel Shin Nichi Maru, the release said. A 3-D inversion of the electromagnetics data for an area of interest for this year’s survey has been completed.

The contract for the 3-D inversion of the data for the entire 2015 survey area has also been awarded to OFG and will be completed in November, the release said.
