INTRODUCTION
Until late in the 1990s we were unable to 'visualize' what was at the bottom of the Hudson River. Then in 1998 the New York State Department of Environmental Conservation through the Hudson River Estuary Program (HREP) began on an extensive mapping project in partnership with Lamont-Doherty Earth Observatory and SUNY Stony Brook. The HREP was interested in learning about the habitats that existed underneath the water in the estuary. The project mapped the estuary bottom from Troy all the way down to the Battery collecting 'information' on the depth, bottom features, bottom surface hardness and sediments, and human impacts. This was done using geophysics (GPS, multibeam swath mapping, sidescan sonar, and subbottom profiling using CHIRP and ground-penetrating radar). Maps were created as part of the project that show river depth, sediment grain size and type, the river bottom shape and the impact of humans on the river.
RESOURCES
Included on this website is information developed from that program made available to "The Day in the Life of the Hudson River" program. The river has been divided into different sections so you can focus on your area with your students. For each section a ppt (also loaded as a pdf) has been provided with background information for you to share with your students if you view the presentation in "notes" view. Small movie fly throughs of the various parts of the river have also been included (credit Frank Nitsche, Lamont-Doherty Earth Observatory). For more visualizations on the Hudson River visit Frank's research page on his website.
