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.

Gas Sampling from Pressure Core |
Science Update - May 18:
Coring was completed in the KC151#3 hole today and preparations for logging were begun. Core 27C returned an empty core barrel. The Hyacinth Rotary Corer (HRC) pressure core attempted as Core 28R was unsuccessful, as was the attempt at piezoprobe insertion. With time running out, the hole was deepened to 440 mbsf and prepared for logging. Core 26R, the HRC pressure core was quantitatively degassed after a full suite of nondestructive logging and imaging experiments. The core was 51 cm in length with minor low-density layers but no obvious indications of gas hydrate. Preliminary results of the degassing experiment suggest that the methane content of the pore water was about saturated with respect to methane hydrate.
Plans:
Start wireline logging and VSP (vertical seismic profile) experiment. Pack up lab equipment and samples, prepare for shipping to various locations at the conclusion of the cruise on Sunday.
