MULTISPECTRAL IMAGERY FROM ERTS-1

In 1970, Congress authorized the deepening of the Tampa Bay channel (Rivers and 
Harbors Act of 1970) froni 34 to 44 feet. In order to determine tke effects of this deepening 
on circulation. water qua!ity, and biota, during and after the construction, the U. S. Geo- 
logical Survey. in cooperation with the Tampa Port Authority, has collected data and de- 
veloped a digital simulation model of !he bay. 
In addition to data collected using conventional tools, i!se is k ing  made of data cob 
lected from ERTS-1. Return-Beam Vidicon (RBV) multispectral data were cdlected, while 
a shell dredgine barge was operating in the bay, and used for turbidity recognitio~l and unique 
spectral signatures representztive of type and amount of material in suspension. The proces- 
sed data integrated with other modeled parameters provide an overview of the dynamics of 
turbid material during dredging periods. A three-dimensional concept of the dynamics of 
th? plume was achieved by superimposing the parts of the plume recognized in each RBV 
band. This provides a background for automatic computer processing of ERTS data and 
three-dimensional modeling of turbidity pfumes
