Bay Effluent Discharge Transport and Dispersion:
is an acoustic backscatter visualization of the presently operating
Deer Island Outfall plume located at an exit of the Boston (Mass)
harbor. The colors correspond to strength of acoustical backscatter.
is an acoustical backscatter visualization of the water column
in Massachusetts Bay extending from the location of the Deer
Island outfall plume (at the extreme right of the figure) to
the location of the diffuser site for the new offshore outfall
presently under construction by the Massachusetts Water Resource
Authority (a total distance of approximately 15 km). Seen in
this visualization is a possible residual Deer Island effluent
plume and a possible plankton ensemble.
is an acoustic backscatter visualization of a portion of Massachusetts
Bay water column at a site in the western boundary area of the
Slethwagen Basin. Shown is what is thought to be a plankton
layer undergoing vertical deformation due to a Lee-like wave
created by tidal flow over bottom topographic features. Also
visible are ensembles of discrete scatters thought to be fish.
