Tidal currents created by COASTMAP Data Services. COASTMAP is a framework used to integrate and deliver data from a variety of numerical models and observation systems. (www.coastmap.com
The current vectors seen here are generated from a tidal model called ADCIRC. Note that these vectors represent only the astronomical tidal component of the currents and not other current flows generated from winds or fresh water inflows.
The vectors are calculated from a database that ASA has developed from original work implemented by the U.S. Army Research and Development Center, Coastal and Hydraulics Laboratory (ERDC/CHL) using ADCIRC simulations (Luettich et al., 1992). ADCIRC is a coastal hydrodynamic circulation model that employs a finite element grid which allows flexible gridding (large elements in deep offshore region and fine elements near coasts).
Applied Science Associates (ASA) is an international leader in the development and application of computer tools to analyze marine and freshwater environments. ASA answers questions about our environment and human interaction within that environment, using computer models to simulate physical, chemical, and biological processes, as well as hydrodynamic models to predict surface and subsurface currents in water bodies all over the world.
