Environmental Monitoring Technologies for Marine Energy


Scientists at PNNL have expertise in marine technology/engineering, biotechnology, biogeochemistry, ecosystems science, toxicology, and earth systems modeling. See https://marine.pnnl.gov for more on the expertise at MSL. Research teams at PNNL involved with coastal and ocean modeling as well as international collaboration and knowledge management support Triton through their abundant resources and collaborations within PNNL.


Coastal and Ocean Modeling


Many of our researchers specialize in state-of-the-art oceanographic, hydrodynamic, water quality, and ecosystem modeling aimed at solving water and natural resource issues in a host of aquatic systems. We use comprehensive numerical modeling to build scientific understanding and support decision-making for all aspects of the water hydrologic cycle. This includes everything from rainfall and runoff from watersheds to flows in small streams to distributed flows in larger river systems to circulation in wetlands, estuaries, and coastal waters. Our modeling capabilities span from simple one-dimensional (1-D) flow and effluent dilution models to complex three-dimensional (3-D) computational fluid dynamic (CFD), hydrodynamic, fate and transport, and comprehensive water quality models.


International Collaboration and Knowledge Management


A team at PNNL has developed Tethys, a global, open-access database that facilitates the exchange of information and data on the environmental effects of both wind and marine renewable energy technologies. Tethys was developed to support the U.S. Department of Energy Water Power Technologies Office and the Wind Energy Technologies Office, and functions as a platform for the International Energy Agency Ocean Energy System’s Annex IV Initiative. Tethys cultivates a collaborative research space for project developers, regulatory agencies, stakeholders, and researchers from around the world to access and share data, connect with the research community, and propel the industry forward. Creators and users of Tethys have a common goal: to detangle and clarify the complex environmental issues associated with MRE and wind energy through the exchange of data and information.
