Purpose, Objectives, & Integration
How do we design an OTEC plant to sustainably and economically process and discharge the massive seawater flows associated with OTEC?
Use a numerical model to quantify OTEC discharge component design, OTEC performance, and environmental changes that may result from OTEC flows.
This bio-plume modeling supports other OTEC development efforts funded by NavFac, Lockheed, ONR and the State of Hawaii

Numerical ocean circulation model of Hawaii. (HIROM)
Numerical simulation of plankton growth caused by nitrate enrichment. (in EFDC)
Validate the circulation model with new (2010) current and density data. (e.g., temperatures at right indicate vertical nutrient oscillation.)
