| Research Abstract |
To investigate the detailed fluid distribution, I renewed our existing deep-towed DC resistivity meter system to improve its performance. The first test observation was conducted in 2009, and an OBEM could obtain the EM signal from this renewed system. On the other hand, new inversion technique with sharp boundary has been improved. As the result, a sharp plate boundary around the plate boundary could be detected using EM data.
