IODP Expedition 330 Louisville Seamount Trail

Daily Science Report 36 -- Sunday, 16 January 2011

Although the drill bit has accumulated 110 hours of rotation, today’s penetration rate (3 m/hr) and recovery (93%) is still record-high. Cores U1374A-59R to -64R (402.8 - 460.3 mbsf) continue to deliver greenish-gray, relatively homogeneous breccia with intercalated lava flows. Whereas two smaller volcanic units are found in U1374A-59R, a massive flow (>7 m recovered) was found in U1374A-60R. The first sampling party for personal, post-expedition research of “hard rock” samples from Site U1372 was conducted in the conference room. This unusual location was chosen to maintain core-processing activities in the core lab for this high-recovery expedition.
