PhD. dissertation
No formal abstract is given. A summary states, "Charles Nittrouer has combined a variety of sedimentological, geochemical, and geophysical techniques to carry out a comprehensive investigation of sediment accumulation in a continental shelf environment. His study area included the Washington and northern Oregon continental shelves, and his investigation involved: extensive box coring of the seabed with subsequent analysis for Pb-210 geochronology, sediment texture and mineralogy, microstratigraphy, and benthic biology; and high resolution seismic reflection profiling for examination of Holocene stratigraphy.
"The distinctive achievements of this dissertation include aspects of both the methods and the results. A budget for sediment accumulation during the past century is established, and evaluated over Holocene time scales. The results of this work significantly improve our understanding of regional sedimentation in the continental shelf environment. The use of independent methodology allows verification of the sedimentological significance of Pb-210 geochronology as a tool for quantitatively determining sediment accumulation rates. This research also lays the groundwork for future investigations of the physical and biological processes that are associated with sediment accumulation and responsible for the preserved stratigraphic record. The concepts developed in this dissertation can be applied to many continental shelf environments, and it is anticipated that they will provide a focal point for future studies by other scientists."
"This study is an investigation of the accumulation of river-borne detrital sediment in a continental shelf environment. The general goal is to elucidate the relationships between sedimentological processes and sediment accumulation, in order to understand the mechanisms by which sedimentary strata are formed on the shelf. This study differs from other process oriented sedimentological studies in that the temporal aspect of shelf sedimentation is directly evaluated."

No estimate made for original data. For inclusion in OFR 00-167, granulometric data were summarized into gravel, sand, silt, and clay fractions. For usSEABED, data were culled from USGS OFR 00-167 and formatted into usSEABED structure. Where appropriate, data were tested for completeness using MS Excel. Locations checked using GIS.
Data fall within normal ranges for the given parameters.
No estimate made for original data. For inclusion into USGS OFR 00-167, individual granulometric measurements are not included; water content and Pb-210 dates were not included. No sub-bottom data (granulometric, summary of granulometric, water content, and Pb-210) are included. For usSEABED, all data in OFR 00-167 provided by this report were included.
No navigational information is given in the original report. Positions given to minute-tenths.
Water depths determination method not recorded in report. Subsample depths given to nearest centimeter.
"Samples from the upper three centimeters of box cores were examined for grain size using a standard sieve (class interval 0.25 phi) and pipette analysis (Krumbein and Pettijohn, 1938)."
