Other ID: none

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Location: Gas Hydrate Laboratory, U.S. Geological Survey, Woods Hole Science Center, 384 Woods Hole Road, Woods Hole, MA 02543

Principal Investigator(s): William Waite

Affiliate Investigator(s):

Information Specialist(s):

Data Type(s): Environmental Data: Wave

Scientific Purpose/Goals: Establish a means of calibrating wave speed measurements made in hydrate-bearing sand by the primary institutions conducting physical property measurements in hydrate-bearing sediment.

Vehicle(s):

Start Date: 2010-08-10

Start Port/Location:

End Date: 2011-04-08

End Port/Location:

Equipment Used: Pig (High-pressure, wave speed measurement cell)

Information to be Derived: Physical property data;

Summary of Activity and Data Gathered: This activity is part of an Interlaboratory Comparison Project designed to compare wave speed measurements made in different laboratories, but on identical samples. Data include waveforms measured with shear-wave transducers on dry sand, water-damp sand, fully water-saturated sand, frozen sand, and hydrate-bearing sand. Results are combined with those from 7 other laboratories in an excel spreadsheet and analyzed in a paper presented at the 7th International Conference on Gas Hydrates (July 17-21, 2011, Edinburgh, Scotland).
