This data release presents pumping rate data, water-level drawdown and recovery data, and atmospheric pressure data collected during 48 pumping tests conducted in 2015 and 2016 for a hydraulic tomography field experiment in the mudstone aquifer underlying the former Naval Air Warfare Center (NAWC), West Trenton, NJ. The pumping rate data include rates measured by in-line flow meters and rates measured manually by recording the time to fill a known volume with the pump discharge water. The water-level drawdown data include drawdowns measured by fiber-optic pressure transducers, and drawdowns measured by strain-gauge transducers. For many tests, water-level recovery data are also provided, which measure the change...
High-angle, open mode fractures control the presence of natural gas hydrate in water-saturated clays at the Keathley Canyon 151 site in the northern Gulf of Mexico, which was investigated for gas hydrates as part of the Chevron Joint Industry Project drilling in 2005. We analyze logging-while-drilling resistivity images and infer that gas hydrate accumulated in situ in two modes: filling fractures and saturating permeable beds. High-angle hydrate-filled fractures are the most common mode for gas hydrate occurrence at this site, with most of these fractures dipping at angles of more than 40° and occurring between 220 and 300 m below seafloor. These fractures all strike approximately N-S, which agrees with the 165°SE-345°NW...
