The map below is a blow-up of
Area 1 Tappan Zee. This is the area we focus on in this website.
The Tappan Zee area stretches
from the Tappan Zee bridge in
the south to Croton Point in the
north. Our interactive map shows
this area in detail.

Hudson River benthic mapping takes
place in 4 main areas. The red rectangle superimposed on the New York State
map above corresponds to the expanded infrared area map in the center.
