Documentation of the U.S. Geological Survey Oceanographic Time-Series Measurement Database

Abstract

The U.S. Geological Survey (USGS) Oceanographic Time-Series Measurements Database contains oceanographic observations made as part of studies designed to increase understanding of sediment transport processes and associated dynamics. Analysis of these data has contributed to more accurate prediction of the movement and fate of sediments and other suspended materials in the coastal ocean. The measurements were collected by investigators at the USGS Woods Hole Science Center (WHSC) and colleagues, beginning in 1975. Most of the field experiments were carried out on the U.S. continental shelf and slope.

This report describes the instrumentation and platforms used to make the measurements; the methods used to process, apply quality-control criteria, and archive the data; and the data storage format. The report also includes instructions on how to access the data from the on-line database at http://stellwagen.er.usgs.gov/. As of 2008, the database contains about 4,250 files which may include observations of current velocity, ocean temperature, conductivity, pressure, and light transmission at one or more depths over some duration of time.
