Bottom Classification by QTC View Near the Dry Tortugas.

Abstract

The research described in this report represents an important step forward in the development of seabed classification technology. First, it represents the application of the QTC VIEW technology to a new seabed environment. The data sets analyzed here involve reef seabeds which have not previously been studied. Second, they represent a consistent effort to compare the results obtained by using two different frequencies of sounder over the same seabed type. The results suggest that both 200 kHz and 24 kHz sounders can be used to classify the four bottom types involved in the study. However, it is clear that multispectral seabed classification holds significant potential in situations where, for example, a gravel bedform is overlain by a thin veneer of mud.
