Bulk-elemental analyses for the upper 350 m of samples from Hole 1150A show relatively high concentrations of organic carbon. Sulfur abundances also are relatively high in this interval. Ethane concentrations are typically about 6 ppm from 700 to 900 mbsf. Values then slightly increase with depth to typical values of about 14 ppm. Other hydrocarbon gases are below detection limit.
Data quality is good throughout the logged intervals.
The whole logged section can be divided into six units using the resistivity log in conjunction with other logs. These units are consistent with core descriptions and core measurements. We continued to prepare and test the electronic and mechanical systems that are part of the borehole instruments. We verified that the digitizing and data logging are all functioning. We modified the support tube for the tiltmeter and seismometers, and started assembling the containers for the digitizer electronics.
