USGS - science for a changing world

USGS Coastal and Marine Geology Program

Technology and Tools

The U.S. Geological Survey (USGS) Coastal and Marine Geology Program (CMGP) conducts integrated mapping of the coastal and marine environment to define offshore hazards and sediment processes, support habitat and resource management, and monitor change. CMGP is an innovator in mapping and laboratory analyses, whose expertise is sought by other governmental agencies, educational institutions, and private companies. In turn, we seek collaborative research and development opportunities with similar groups to continually correct and perfect the data collection tools, analytical techniques, and technologies utilized in our coastal and marine studies.

Mapping Technologies

Lidar for Science and Resource Management: aircraft-mounted light detection and ranging (lidar) and multi-spectral imaging to map coastal-marine and terrestrial environments

Advanced Remote Sensing Methods for Coastal Science and Management: characterizing and classifying features on the seafloor using data collected by both airborne and underwater instrumentation; ATRIS, topographic complexity, coral fluorescence

Louisiana Sedimentary and Environmental Database: database incorporates a wide range of data types (sediment-sample logs and analyses, geophysical profiles, raster-image basemaps, logbooks, etc.) that are integrated with spatial data

Mapping Systems: surficial, sub-bottom, and littoral mapping; sampling (Pacific Coastal and Marine Science Center)

More Mapping Systems: surficial, sub-bottom, and littoral mapping; sampling (Woods Hole Coastal and Marine Science Center)

Maps of America's Submerged Lands: provides links to publications that contain maps and the digital data used to create them

Laboratories

Core Splitting and Description Lab: equipped for splitting, describing, photographing, and subsampling of sediment cores and other marine samples

Gas Hydrates Project Laboratories: measures the physical properties of natural and synthetic hydrate-bearing sediments using the Instrumented Pressure Testing Chamber (IPTC) and a modular system of laboratory cells and peripherals

GeoTech Lab: specializes in geotechnical studies of marine, estuarine, lacustrine, and terrestrial sediment. Capabilities include fully automated computer-controlled testing of consolidation, permeability, and shear strength properties as well as non-destructive analysis of whole-core sediment sections using a whole-core logging system. Useful for submarine and earthquake failure analysis

Sediment Lab: equipped to determine the basic attributes of marine sediments

X-Ray Diffraction Lab: used to study the characteristics of crystalline structure and determine the mineralogy of finer grained sediments

Software
