The U.S. Geological Survey (USGS), in cooperation with the Arkansas Geological Survey (AGS), has gathered available geophysical logs and related data from the USGS office archives in Arkansas and Tennessee as a basis for developing a hydrogeologic framework for the Southeast region of the United States. Similar efforts were undertaken by the Mississippi Embayment Regional Aquifer Study (MERAS) and the Regional Aquifer-System Analysis (RASA) Program. The logs compiled for these older efforts were difficult to access from the paper files; however, and partly because of this, older and newer logs were compiled into a single digital database for the current study.

Understanding how effectively methane can be extracted from a gas hydrate reservoir requires knowing how compressible, permeable, and strong the overlying seal sediment is. This data release provides results for flow-through permeability, consolidation, and direct shear measurements made on fine-grained seal sediment from Site NGHP-02-08 offshore eastern India. The sediment was collected in a pressure core from the Krishna-Godavari Basin during the 2015 Indian National Gas Hydrate Program Expedition 2 (NGHP-02). Gas hydrate is a crystalline solid that forms naturally in the sediment of certain marine and permafrost environments where pressure is relatively high (equivalent to the pressure measured ~300 meters water...

Meteor Crater, located in northern Arizona, is one of the best preserved and easily accessible impact sites on Earth. Scientific investigations of this crater have led to improvements in our understanding of impact mechanics, cratering dynamics, and ejecta distribution [e.g., 1-5]. In addition, this site has a rich history as a terrestrial analog that has been used for training astronauts, scientists, and engineers [e.g., 6-8]. In the 1970s Dr. David Roddy conducted a rotary drilling campaign at Meteor Crater, along the rim, flanks, and surrounding ejecta blanket [9]. This work resulted in 2,500 m of drill cuttings from 161 drill holes. The original samples were placed in sandwich-sized plastic bags with slips of...
