Critical military training and testing on lands along the nation’s coastal and estuarine shorelines are increasingly placed at risk because of development pressures in surrounding areas, impairments due to other anthropogenic disturbances, and increasing requirements for compliance with environmental regulations. The U.S. Department of Defense (DoD) intends to enhance and sustain its training and testing assets and to optimize its stewardship of natural resources through the development and application of an ecosystem-based management approach on DoD installations. To accomplish this goal, particularly for installations in estuarine/coastal environments, the Strategic Environmental Research and Development Program (SERDP) launched the Defense Coastal/Estuarine Research Program (DCERP) as a minimum 10-year effort at Marine Corps Base Camp Lejeune (MCBCL) in North Carolina. The results of the first six years of the program (DCERP1) are presented here.The overarching objectives of DCERP are to: (1) understand the effects of military training activities, infrastructure development, and other coastal military installations; (2) develop models, tools, and indicators to evaluate ecosystem health; and (3) recommend adaptive management strategies to sustain ecosystem natural resources within the context of an active military installation.This data package includes seismic sub-bottom profile data are from the shallow (-2 to -11.5m, NAVD88) nearshore region of Onslow Beach. Data were collected in 2007 using a high-resolution Edgetech Chirp 512i (average resolution of 10-20cm). The position of each data point was related to NAD83 using RTK-GPS. Data were collected at a frequency range of 0.5-8 kHz. Heave is apparent in the seismic profiles because no swell filter was applied during acquisition or post-processing. Post-processing was performed using Chesapeake Technology SonarWiz MAP5. Georeferenced .sd files (datums: UTM, Zone 18N, meters & NAVD88, meters) were generated using IVS Fledermaus Pro ver. 7.
