Environmental Sciences Division at the Space and Naval Warfare Systems Center, San Diego


The Environmental Sciences Division is part of the Space and Naval Warfare Systems Center (SPAWARSYSCEN, formerly NRaD) in San Diego, California. The Division is a leader in marine environmental quality assessment, sensor development, and remediation. The Division draws on a broad range of in-house expertise and partnerships with industry, academia, and government to research, develop, test, and evaluate environmental technology to support the Navy's goals for:
  • Environmentally safe ships and shore facilities
  • Identification and remediation of hazardous waste disposal sites
  • Regulatory compliance
  • Compliance cost reduction
  • Pollution prevention
  • Protection of natural resources

The Environmental Sciences Division of SPAWAR Systems Center San Diego (SSC SD) is actively focused on marine environmental quality assessment, sensor development, environmental data analysis and remediation technologies. Our group has been active in the field of Ecological Risk Assessment (ERA) and its precursor sciences since the early 1970's. Division personnel bring a multi-disciplinary approach to ERAs and have applied the knowledge and methodologies developed during this period to the assessment of numerous Navy Comprehensive Environmental Response, Compensation and Liability Act/Resource Conservation and Recovery Act (CERCLA/RCRA) and BRAC sites. Their expertise in the areas of environmental chemistry/geochemistry, toxicology, oceanography, environmental data management and analysis have been applied to various ecological risk assessments to support compliance and NEPA, as well as aquatic hazardous waste sites. The "EcoRisk" model has also been used by the Division to propose environmental standards that are both scientifically defensible and acceptable to Fleet operations and facility environmental management.

To meet Navy needs for marine environmental monitoring and risk analysis, SSC SD has developed a Marine Environmental Survey Capability (MESC). The MESC integrates state-of-the-art sensors, computer systems, and navigation equipment to determine spatial and temporal variability of physical and chemical water quality characteristics from a moving vessel in near real-time. The MESC system was developed by the Navy to address water quality issues related to the operation of ships and facilities in the coastal environment. SSC SD has also been active in RDT&E to support ERA with the development of instruments and methods to support rapid and cost-effective risk analysis, including:
