CHEMMAP is a chemical discharge modeling and response system that predicts the transport, fate, and biological impacts of a wide variety of chemical substances in the marine environment and atmosphere.

Applications of CHEMMAP

  • Emergency response
  • Risk assessment
  • Contingency planning- including worst case scenario
  • Natural resource damage assessment
  • Drills and education
  • Cost-benefit analysis

  • Interactive GIS
  • Access to real-time met-ocean data via EDS


  • 3D chemical transport and fate model in water and air
  • Includes integrated GIS, compatible with other GIS tools
  • World-wide application
  • Includes algorithms for dissolution, evaporation, volatilization, sediment interaction, adsorption, shoreline interaction
  • Easy to interpret visualization of chemical concentrations over time
  • Seamlessly linked to AIRMAP
  • Biological exposure model to predict exposed fish and wildlife impacts
  • Extensive chemical database providing physical-chemical data for over 900 chemicals
  • EDS: Environmental Data Server integration

CHEMMAP modules

CHEMMAP simulates the following processes:

  • Initial plume dynamics
  • Slick spreading, transport, and entrainment of floating materials
  • Evaporation and volatilization (to atmosphere)
  • Transport and dispersion of dissolved and particulate materials in the water column and in the atmosphere
  • Dissolution and adsorption to suspended sediments
  • Sedimentation and resuspension
  • Natural degradation
  • Shoreline interaction
