Historical Shorelines for Fire Island and Great South Bay, New York (1834 to 1875): Georeferenced Topographic Sheets and Vector Digital Data Historical Shorelines for Fire Island and Great South Bay, New York (1834 to 1875): Georeferenced Topographic Sheets and Vector Digital Data
Topographic sheets (t-sheets) produced by the National Ocean Service (NOS) during the 1800s provide the position of past shorelines. The shoreline data can be vectorized into a geographic information system (GIS) and compared to modern shoreline data to calculate estimates of long-term shoreline rates of change. Many t-sheets were scanned and digitized by the National Oceanic and...
Data Release for the 2018 U.S. Geological Survey - California Geological Survey Fault-Imaging Surveys Across the Hollywood and Santa Monica Faults, Los Angeles County, California Data Release for the 2018 U.S. Geological Survey - California Geological Survey Fault-Imaging Surveys Across the Hollywood and Santa Monica Faults, Los Angeles County, California
We acquired multiple types of controlled-source seismic data across the Hollywood Fault in Hollywood, Calif., and the Santa Monica Fault in Beverly Hills, Calif., in May and June of 2018. We acquired two separate profiles across the Hollywood Fault, and from those data we can evaluate multiple seismic datasets and calculate seismic models including guided-wave data, tomographic VP data
Data and Shapefiles for the Potentiometric Surface of the South Coast Aquifer and Hydrologic Conditions in the Santa Isabel area, Puerto Rico, March-April 2014 Data and Shapefiles for the Potentiometric Surface of the South Coast Aquifer and Hydrologic Conditions in the Santa Isabel area, Puerto Rico, March-April 2014
A groundwater-level survey and reconnaissance of the hydrologic conditions in the coastal alluvial plain of southern Puerto Rico was conducted by the U.S. Geological Survey, in cooperation with the Puerto Rico Department of Natural and Environmental Resources. The objective of the field survey was to delineate the potentiometric surface of the coastal alluvial aquifer between the Rio...
