An effort to map the bottom of the Hudson River estuary has yielded important insights into how sediment and contaminants move-while also producing fascinating images of numerous long-lost ships. NEIWPCC's John Ladd, Ph.D., is overseeing the benthic mapping project, which uses sophisticated sonar systems to create images of the river's floor. The mapping process is providing scientists with an incredibly detailed look at the river bottom's configuration, leading to new discoveries about the river's dynamics and life forms. This information is useful in the effort to effectively manage the estuary.
