Summary
The development of Submerged Aquatic Vegetation (SAV) growth model within the Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST) model leads to a change in SAV biomass. The SAV biomass is computed from temperature, nutrient loading and light predictions obtained from coupled hydrodynamics (temperature), bio-geochemistry (nutrients) and bio-optical (light) models. In exchange, the growth of SAV sequesters or contributes nutrients from the water column and sediment layers. The presence of SAV modulates current and wave attenuation and consequently affects modelled sediment transport. The model of West Falmouth Harbor in Massachusetts, USA was simulated to study the seagrass growth/dieback pattern in a hypothetical scenario. The [...]

The presence of SAV modulates current and wave attenuation and consequently affects modelled sediment transport. The model of West Falmouth Harbor in Massachusetts, USA was simulated to study the seagrass growth/dieback pattern in a hypothetical scenario. The model setup was simulated for 56 days, beginning 2 July 2010.

The model domain was developed to test the fully coupled hydrodynamic, biogeochemical, and vegetation model dynamics and study the influence of the presence and absence of nitrate loading on seagrass in West Falmouth Harbor, Massachusetts, USA. These model results may also be reused to support any prospective research work where appropriate.
The data release was modified to include the gzipped tar file of the version of the model code used to generate the results presented in the data release.
