Abstract
The dynamics of the Chesapeake Bay plume have been studied by examination of 81 dates of Landsat images with color additive enhancement and single-band density slicing. The "plume" was interpreted from surface turbidity discontinuties as revealed in images from multispectral scanner (MSS) bands 4-7. Results show that the Chesapeake Bay plume usually frequents the Virginia coast south of the Bay mouth. Wind and tide vectors are the principal variables affecting the plume dynamics. Southwestern (compared to northern) winds spread and disperse the plume easterly over a large area. Ebb tide images (compared to flood tide images) show a more dispersed plume. Flooding waters produce high turbidity levels over the shallow northern portion of the Bay mouth.
