Title:

CERCTM34: USACE ICONS Cores, Palm Beach to Cape Kennedy, Florida

Abstract:

The Inner Continental Shelf off eastern Florida was surveyed by CERC to obtain information on bottom morphology and sediments, subbottom structure, and sand deposits suitable for restoration of nearby beaches. Primary survey data consists of seismic reflection profiles and sediment cores. This report covers that part of the survey area comprising the inner Shelf between Palm Beach and Cape Kennedy. Sediment on beaches adjacent to the study area consists of quartzose sand and shell fragments. Median size of midtide samples generally lies in the range betwen 0.3 to 0.5 mm. (1.74 to 1.0 phi) diameter. The Shelf in the study area is a submerged sedimentary plain of low relief. Ridge-like shoals generally of medium-to-coarse (0.25 to 1.0mm.) calcareous sand resting on the seaward dipping subbottom strata contain material suitable for beach restoration. A minumum volume of 92.2 X 106 cubic yards of suitable sand is available within study limits..

   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 (104)

   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 0.000000. Longitudes are given to the nearest 0.000000. 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.
      The semi-major axis of the ellipsoid used is 6378206.400000.
      The flattening of the ellipsoid used is 1/294.978698.

   Entity_and_Attribute_Overview:

   Sample identifiers, navigation, core descriptions, and grain size statistics from the USACOE ICONS program project from Palm Beach to Cape Kenndey, Florida. Some enries for top and bottom depths were originally reported as "top." In the digital files, "top" was changed and defined as 0-0.02 meters.
