Assessment of Gas Hydrate Resources in the North Slope of Alaska, 2018

The U.S. Geological Survey (USGS) has updated the previous 2008 assessment of undiscovered, technically recoverable gas hydrate resources beneath the North Slope of Alaska.  This new 2018 assessment again indicates the existence of technically recoverable gas hydrate resources―that is, resources that can be discovered, developed, and produced using current technology.  Using a geology-based...

Creating a Model to Predict Future Carbon Levels in Tidally-driven Marshes

Tidal marshes are important ecosystems in the San Francisco-Bay Delta. They remove carbon from the atmosphere, they build up soils that buffer our communities from sea level rise, they provide critical habitat and food resources for a diversity of species, and they reduce excessive nutrients which have a negative impact on water quality. As a result of land-use change and urbanization, the San...

Refined Model Provides a Screening Tool to Understand Exposure to Contaminants from Incidental Wastewater Reuse

Refinement of the existing national-scale “de facto reuse incidence in our nation’s consumable supply” (DRINCS) model, complemented by field measurements, provides a screening tool to understand human and wildlife exposure to toxicants and pathogens associated with the incidental reuse of treated wastewater in the Shenandoah River watershed. The model results can be accessed in a companion...

    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.
