After a successful (open hole) re-entry into U1376A in the early morning, coring of the massive, highly olivine-augite-phyric lava flow continued today with Cores U1376A-11R and -12R (86.8 to 101.2 mbsf). Drilling has now advanced 28 m into this single unit with an excellent recovery of 90% but with an extremely slow penetration rate of ~1m/hr. At noon, the U1375 Site Meeting was conducted with joint presentations from the Sedimentology, Paleontology, Igneous Petrology, Alteration Petrology and Structural Geology lab groups. The U1375 Site Reports were submitted by the end of the day.
