The wireline winch which is used for lowering down the hydrophone and the instruments for the geophysical borehole logging has arrived the drilling site on level 95. Furthermore, Dr. Hiroshi Ogasawara will take the hydrophone underground tomorrow, hence the hydrophone tests can be undertaken this week. On surface, Michael has finished the subdivision of core runs and core sections and he is now busy to tip the data into the Drilling Information System (DIS).
