Title:
Sedimentary Environments in Apalachicola Bay and Vicinity (John W. Kofoed Thesis)
Abstract:
The purpose of this investigation is to determine the distribution of sediment transported by the Apalaohicola River into Apalachicola Bay and vicinity and to determine factors which would aid in the interpretation of similar ancient environments recorded in sedimentary rocks. This objective is based on the premise that the factors and the forces presently acting upon the sediment types are similar to those of the geologic past. The nature and variability of the sediments were investigated by statistical procedures to quantitatively evaluate the parameters of sedimentation; source, transport, site of deposition and diagenesis. In addition, associations of primary sedimentary structures with environment and sediment distribution were also studied. Data of this nature offer a detailed understanding of the environment and permit a quantitative approach to the lithostratigraphic problems of finding similar environments in the rock record.

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):

      • Entity point (110)

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.0000. Longitudes are given to the nearest 0.0000. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1927.
      The ellipsoid used is Clarke 1866.
