What does this data set describe?
    Title: BUYNEVICH01: Fluvial-Marine Interactions, Maine
    Abstract:
    Grab samples and cores were collected as part of a study of the fluvial-marine interaction in the system comprised by the Kennebec River, Androscoggin River, Merrymeeting Bay, and Kennebec River Estuary. Processes controlling the Holocene evolution of the Popham Barrier were also examined.

Why was the data set created?
The purpose of this data layer is to make available a digital subset of a data set produced by I. Buynevich as part of a Ph.D. dissertation from Boston University.

How was the data set created?
  1. From what previous works were the data drawn?

    (source 1 of 1)
    Buynevich, I.V., 2001, Fluvial-marine interaction and Holocene evolution of sandy barriers along an indented paraglacial coastline: Doctoral Dissertation 317 p., Boston University, Boston, MA.

    Type_of_Source_Media: MS Excel spreadsheet

  2. How were the data generated, processed, and modified?

    Date: 13-Jan-2003 (process 1 of 1)
    Textural data from fluvial and estuarine environments of southwestern Maine were reorganized in Excel and exported to an ASCII file. Stations and sediment data were imported from the ASCII text file to an ArcView table. The table was later converted to an event theme and saved as the final shapefile.

How reliable are the data; what problems remain in the data set?
  1. How well have the observations been checked?

    All attributes were checked by the compilers in a consistent manner.

  2. How accurate are the geographic locations?

    Navigation was by differential GPS. Error +/- 10 m.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    Identifiers, navigation, grain-size data, and textural classification are provided for 388 stations.

  5. How consistent are the relationships among the observations, including topology?

    No additional checks for topological consistency were performed on the data

How can someone get a copy of the data set?
Are there legal restrictions on access or use of the data?

Access_Constraints: None
Use_Constraints: None
