Satellite imagery of the north-central Gulf of Mexico, June 1993-May 1997

This CD contains imagery collected by the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA polar-orbiting weather satellites. The AVHRR provides almost daily coverage of a site at a resolution of approximately 1 km. The data types included are sea surface temperature (SST), water reflectance (REF), and a false-color infrared overview (FCI).

Proceedings of Conference on Status of Geologic Research and Mapping, Death Valley National Park

Welcome to this conference on the “Status of Geologic Research and Mapping in Death Valley National Park.” We organized this conference in an effort to foster communication and increase awareness among parties conducting geologic research in and around the park. Additionally, we hope to assess the status of geologic mapping efforts within the park boundaries in an effort to provide a framework for future discussions regarding the impact and merits of the development of a park-wide geologic map. The topics presented at this meeting reflect the breadth of recent and ongoing geologic research in and near Death Valley National Park. Sessions include (1) regional structure, tectonics, and bedrock geology; (2) Neogene basin stratigraphy, geophysics, and hydrology; (3) posters on mapping in the Death Valley region and topical ones on Death Valley National Park; (4) imagery, Quaternary stratigraphy and geomorphology, and Quaternary geochronology; and (5) paleoclimate and active tectonics. On a one-day field trip to Death Valley, we will visit areas of “type locality” status as well as areas of new research.

Digital map of water-level changes in the High Plains Aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming, 1980 to 1995

This data set consists of digital water-level-change contours for the High Plains aquifer in the central United States, 1980 to 1995. The High Plains aquifer extends from south of 32 degrees to almost 44 degrees north latitude and from 96 degrees 30 minutes to 104 degrees west longitude. The aquifer underlies about 174,000 square miles in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital data set was created from 5,892 wells measured in both 1980 and 1995. The water-level-change contours were drawn manually on mylar. The contours were converted to a digital map at a scale of 1:1,250,000. The data should not be used at scales larger than 1:1,250,000.
