  Description:
    Abstract:
      The dataset contains the core number, location, latitude/longitude,
      date collected, and core surface description for cores from Rabbitt
      Key, Cluett Key, Whipray Basin, Bob Allen Key, Rankin Bight, Lake
      Ingraham, Russell Bank, Johnson Key, Porjoe Key, Trout Creek, Little
      Madeira Bay, Crcodile Point, Pass Key, and Park Key
    Purpose:
      The use of radioactive isotopes is founded on the known physical
      property of radioactive material, the half-life.  A half-life of an
      isotope is the amount of time it takes for half of a given number of
      atoms to "decay" to another element.  The age of objects that contain
      radioactive isotopes with known half-lives can be calculated by
      determining the percent of the remaining radioactive material.  To use
      this method successfully certain other prerequisites must be met.
      These are: 1. the chemistry of the nuclide (element) is known; 2. once
      the nuclide is incorporated into the substrate the only change is
      radioactive decay, and 3. in order to be useful, it is relatively easy
      to measure.  The objective of the project is to measure the
      distribution of short-lived radionuclides to provide a temporal
      component to the processes at work within the Ecosystem.

      Process_Description:
        Long cores (>1 m in length), were taken in >30 cm of water through
        the "moon pool" of a motorized 25 ft pontoon barge either grounded
        on the bank or anchored with 4 anchors.  The location was
        established by GPS.
