Occurrence and variation in Submersed Aquatic Vegetation along the northern coast of the Gulf of Mexico

Duration

September 2012 - August 2018

Narrative

Submersed aquatic vegetation (SAV) communities are highly productive ecosystems that provide significant ecological benefits within coastal areas, including support for many important species of fish and wildlife. Despite their critical importance, and loss globally, we lack consistent baseline data on SAV resources across the coastal salinity gradient. This project will provide data on the occurrence and abundance of SAV resources (e.g., coverage, composition, seed resources) within the northern Gulf of Mexico, quantitatively assess environmental factors affecting its spatial and temporal variation and develop a conceptual model of factors influencing SAV resources. These data are critical in identifying empirical relationships between SAV resources and environmental variables, and will enable predictive modeling of SAV resources under different scenarios of landscape and climate change.
