Figure 11. JNOC seismic line JA90-31 for the eastern drilling transect, overlain with spectral gamma radiation (right curve at each site), bulk density (left curve at Sites 1131 and 1129), and porosity (left curve at Site 1127) from the downhole logs. Because of high H2S in the drill hole at Site 1127, the nuclear source of the HLDS was not used. Thus, there are no bulk density estimates for this site. All data were converted to two-way traveltime using a linear interpolation of traveltime from the seafloor to the bottom of the drilled interval.
