Woods Hole Coastal and Marine Science Center Technology and Tools

USGS Gas Hydrate Project Laboratories - Methane and water can combine to form solid, ice-like gas hydrate under the pressure and temperature conditions that characterize the sediments of continental margins and permafrost areas. Our laboratories measure 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, respectively. These properties are particularly critical for understanding the energy and geohazard aspects of gas hydrates.  
Modeling - The U.S. Geological Survey and others are promoting the development of an open-source numerical model for sediment-transport in coastal regions. We are collaborating with other federal agencies, academic institutions, and private industry, with the goal of adopting and/or developing one or more models for use as scientific tools by the research community. We hope these models will evolve into standards for us, and possibly for use in applications by the broader community interested in coastal issues.  
Sea Floor Mapping - Our operational group provides the technical expertise and innovations to plan, acquire, process, interpret, archive, and publish Sea-floor Mapping products to support the USGS and WHSC's coastal, and inner-continental shelf geology, sediment transport, environmental geoscience, and energy/tectonics research programs.  
Analytical Laboratories - This lab is equipped to determine the basic attributes of marine sediments. Grain size analysis equipment includes a rapid sediment analyzer, sieves, and sieve shakers to determine distributions within the coarse fraction, and a Coulter Counter, a constant temperature bath, and settling tubes to determine distributions within the fine fraction. Available computer software allows users to acquire, process, display, and archive the textural data. Camera-ready petrographic and binocular microscopes are available to facilitate compositional analysis.  
Sediment Transport- The Sediment Transport Instrumentation Facility at the USGS Woods Hole Field Center maintains and deploys oceanographic instrumentation for the study of coastal and ocean circulation and sediment transport. The time-series observations are used in studies of regional circulation, to document and understand processes of sediment transport (including major storms and catastrophic events), and provide observations for circulation and sediment transport model testing and evaluation. Instruments are typically deployed for 1-12 months in spatial arrays as part of process or long-term monitoring studies.
