Map showing location of the study area.
Bathymetric contours are in meters.
Boxed area shows extent of geophysical and geologic survey. The New York Bight Apex is one of the most heavily populated impacted coastal regions of the United States. A regional synthesis of the sea floor geology is needed to provide the information necessary to address these issues from a system-wide perspective. The USGS mapping program includes a description of sedimentary environments, sediment texture and chemistry, sea-floor morphology, geologic history, and the geometry and structure of the Quaternary strata. Over the past 80 years, the New York Bight Apex has received about 250 million cubic meters of dredged material and construction waste.
