Sediment Transport Instrumentation Facility (STIF)


Overview

The U.S. Geological Survey (USGS) Sediment Transport Instrumentation Facility (STIF), part of the USGS Woods Hole Coastal and Marine Science Center, provides operational support for studies of coastal ocean circulation and sediment transport. The STIF designs, fabricates, deploys and recovers a variety of instrumented platforms for research.   It has capabilities in engineering, software development, project management, data acquisition, data processing and data archiving. Instrument measurement quality assessments, interface design, and development of novel housings are all examples of the engineering tasks routinely completed. The STIF maintains a diverse pool of high-quality oceanographic instruments, and develop new techniques to improve or modify existing sensors and systems. Field experiments are conducted in estuarine, coastal, and continental shelf regions. Oceanographic moorings, tripods and other platforms are deployed at water depths ranges from less than a meter to more than a thousand meters.

The STIF team members have extensive experience in collecting and managing oceanographic data from deep water to near shore environments.  They support research projects carried out by scientists at the USGS Woods Hole Coastal and Marine Science Center and their colleagues, with assistance to other programs as resources allow.

The data collected are typically comprised of measurements from sensors deployed in arrays at fixed locations. These time-series observations are used in studies of regional circulation and sediment transport processes in estuaries, marshes, beach regions and in the coastal ocean. The observation periods range from a few days to more than a year.   Since 1975, the STIF has deployed over 1000 separate platforms in support of field research programs.

An extensive software system has been developed and maintained to decode, process, edit, display, archive and analyze the oceanographic data collected. This system uses Matlab® and outputs files in EPIC-compliant NetCDF format. CF-Compliant NetCDF files are also created and are available at [http://cfconventions.org].

Time series observations collected throughout the U.S. Exclusive Economic Zone (E.E.Z.) by the group since 1975 are managed, archived and distributed to collaborators, other investigators, and the public over the World Wide Web as part of the U.S. Geological Survey Oceanographic Time-Series Database (see http://stellwagen.er.usgs.gov). File downloads and access via OPeNDAP are possible from the page describing each experiment.
