Ocean Wave Dissipation and Energy Balance (WAVE-DB): Toward Reliable Spectra and First Breaking Statistics
Lead PI: Dr. Fabrice Ardhuin, Service Hydrographique et Oceanographique de la Marine (SHOM)
The proposed work is aimed at improving wave prediction models by improving wave dissipation parameterizations and field observations. Emphasis will be given to swell dissipation due to air-sea interaction and new field measurements, in conjunction with other research efforts at the PI’s institute.

Observation-based Dissipation and Input Terms for Spectral Wave Models, with End-user Testing
Lead PI: Dr. Alexander Babanin, Swinburne University of Technology
The proposed reserach is aimed at improving wave prediction models by taking the advantage of new development in dissipation and input terms in the PI’s institution and collaborations with three end user groups in the U.S. New source terms for breaking dissipation and energy input based on field measurements in Lake George will be refined, implemented and tested by a partnership among a university (Australia) and three federal laboratories.

TSA-A Two Scale Approximation for Wind-generated Ocean Surface Waves
Lead PI: Dr. William Perrie, Bedford Institute of Oceanography
The goals of this proposal are to provide an accurate, efficient computational model of the 4-wave interactions, using the two-scale approximation (TSA), that can be used in operational models of coastal, regional, and ocean basins, and provide a seamless transition from deep water to just outside of the surf zone.
