X-Radiographs Data
Listed in NASA Earthdata CMR
The x-radiographs of Florida Bay cores were used to examine the internal sediment structure of sediment contained in a core and assess whether the sediment was mixed.
Description
In order to manage an ecosystem, it is imperative to define the rate at which ecologic, physical and chemical changes have occurred. The lack of historical records documenting ecological changes dictates that other methods are used to measure the rate of change.
A common method of "dating" change is to measure the decay of naturally occurring radioactive nuclides.
