During this expedition we will maintain a log of information relayed from the chief Scientist on the expedition. Whenever possible, images will be displayed along with the text.
April 25 - Day 9 - Status Report
25 April 2005 - On Location Atwater Valley Block 13 - Coring
Location: On location Atwater Valley Block 13
Science Update: Moved from AT14 to AT13. We revised the coring plan for AT13#2 after reviewing all of the LWD results. The plan now is to core intervals 0-45, 115-152, and 220-257 meters beneath the sea floor. This will require 16 FHPC nonpressurized cores and 7 FHC/HRC pressurized. The revised coring plan was based on reinterpretation of the full suite of LWD logs, with focus on the mid-depth range (115-152 mbsf) amplitude anomaly, interpreted as possible gas hydrate-cemented mud, overlain by carbonate cemented mud.
Plans: Expect first core this evening about 0200 hrs.
