The National Methane Hydrates R&D Program
The DOE/JIP Gulf of Mexico Hydrate Research Cruise
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 21 - Day 5 - Status Report
21 April 2005 - On location at Atwater Valley Block 14
Location: On location Atwater Valley Block 14
Science Update: AV13#1 LWD hole was terminated at a depth of 261 meters beneath the sea floor. Preliminary analysis of the pulsed log results indicates some zones of possible hydrate occurrence. Uncle John moved to location of proposed LWD hole AT14#1. Attempt at ROV push coring of shallow sediments while setting the beacons was unsuccessful. Topics at daily science meeting included a review of AV13#1 preliminary log results and a discussion of strategies for shipboard pressure core experiments. The gas chromatograph has been installed and calibrated, and was used for headspace gas analysis of sediment from one of the shallow push cores taken at AV13#1.Besides air gases, the samples contained only small amounts of carbon dioxide. Methane and hydrogen sulfide were below detection levels.
Plans: Interpret logs on AV14#1 in context of seismic data to plan core coverage and other measurements for proposed AV13#2 hole.
