Oysters generate provide numerous large-scale benefits to the environment, termed ecosystem services. Understanding how these services are also influenced by prevailing environmental conditions, preserved or reduced under cultivation, or can be bolstered through restoration is an important focus of the Gray Lab.

Filtration Services

Arguably the most recognized ecosystem service provided by oysters is their filtration services. Oysters are thought to ‘clean the water’, right? As oysters filter-feed, they remove particles from suspension and deposit them on the seafloor. This activity can improve water quality and clarity:

The Gray lab has conducted numerous studies seeking to improve resolution about the intensity and frequency at which oysters clear water and process particles under laboratory and field conditions. Currently, Lab member Laura Wiltsee (MS graduate research assistant) is applying high-tech solutions for resolving long-standing questions on variations in oyster feeding rates over time. The Gray lab is continually seeking new methods and approaches to improve the accuracy of feeding rate measurements and the models that extrapolate these services to ecosystem scales.

Shoreline Stabilization

Historically, large populations formed massive reefs that dampen waves and prevent shoreline erosion. These can be termed shoreline stabilization services

Creating ‘living breakwaters’ or inclusion of oysters into existing grey infrastructure, such as the jetty show in the video below, are just a couple of examples that oysters could be used to improve and protect the environment.

The Gray lab is currently working on several projects seeking to understand how oyster restoration can be used to improve coastal infrastructure and protect coastal communities.
