Psuty NP, McLoughlin S, Schmelz W, Robertson W, Spahn A. 2018. Development of the geomorphological map for Gateway National Recreation Area: Principal characteristics and components. Natural Resource Report. NPS/NRSS/GRD/NRR—2018/1600. National Park Service. Fort Collins, Colorado
This report incorporates the geomorphological map, its philosophical underpinnings, legend descriptions, and the GIS data layers for the three Units of Gateway National Recreation Area, Sandy Hook Unit NJ, Staten Island Unit NY, and Jamaica Bay Unit NY. The theme of the map follows the current scientific organization of geomorphological mapping that includes morphometrics, causative processes, and evolutionary stages. Surface form was interpreted from a variety of data that include recent orthophotos, recent Light Detection and Ranging (LiDAR) data sets, and spatial information on soils and vegetation. The archival information was augmented with field visits. The geomorphological features of the Gateway site include: 1) a portion of a glacial terminal moraine; 2) coastal topography that was created during an early phase of coastal barrier spit / barrier island development; 3) coastal topography that developed with the downdrift extension of the barrier spit / barrier island systems; 4) coastal topography associated with the estuarine margins of embayments situated inland of the developing barrier spits / barrier islands; and 5) cultural modifications to the natural topography, consisting of excavation as well as accumulation. The geomorphological maps of the Units and their subdivisions and the map legend portray the spatial and temporal association of the surface features created during the several stages of landscape development, as well as the broad cultural modifications of the surface. This portrayal of surface form is based on data sets from 2010. A post-Hurricane Sandy geomorphological map has been prepared by these authors and is available as Psuty et al. (2017).
