An Eco-immunological Study of Chesapeake Bay Waterfowl

The Challenge: The health of the abundant waterfowl species of Chesapeake Bay has become a major concern due to the spread of Avian Influenza (AI) across North America and the role of waterfowl as a vector of AI. For decades, the health of the Bay’s waterfowl has been affected by the degradation of water quality and food supply due to industrial contaminants,agricultural run-off, pollution...

Summary of Monthly Hydrologic Conditions in New Jersey

The U.S. Geological Survey New Jersey Water Science Center’s monthly summary reports and tables of hydrologic conditions for surface and ground water are based on average monthly conditions for the period of record at each index station. Statistical analyses that correlate current conditions with previous climatic extremes are commonly used to develop these averages.

Estuarine Processes Eutrophication

Increased loadings of nutrients to estuaries have altered ecosystem function by encouraging growth of phytoplankton and macroalgae while inducing large swings in dissolved oxygen and threatening the sustainability of seagrass meadows. We are measuring and modeling these processes to understand the future trajectory of estuarine ecosystems.

Estuarine Processes Tidal Wetlands

Tidal wetlands are an important geomorphic and ecological feature of the coastal zone. Our projects deal with the physical forcings that affect wetland stability over event-to-annual timescales, including wave attack, sediment supply, and sea-level rise.

Estuarine Processes Coastal Hazards

Extreme tides and coastal storms transfer high water levels to estuaries through natural and managed entrances. The size of the transfer depends on the duration of the event and the geomorphology of the estuary. We use observational data and modeling scenarios to understand and spatially map this transfer at our study sites.

China’s domestic and foreign influence in the global cobalt supply chain

In addition to increasing interest in the supply risk of minerals produced in China, there is also concern that China’s efforts to mitigate mineral supply risk—through foreign direct investment—may limit mineral availability for other countries in the short-term (due to production capacity constraints). However, little is publicly known about the...

Global virtual water trade and the hydrological cycle: Patterns, drivers, and socio-environmental impacts

The increasing global demand for farmland products is placing unprecedented pressure on the global agricultural system and its water resources. Many regions of the world, that are affected by a chronic water scarcity relative to their population, strongly depend on the import of agricultural commodities and associated embodied (or virtual) water....

Geochemical and mineralogical maps, with interpretation, for soils of the conterminous United States

Between 2007 and 2013, the U.S. Geological Survey conducted a low-density (1 site per 1,600 square kilometers, 4,857 sites) geochemical and mineralogical survey of soils in the conterminous United States. The sampling protocol for the national-scale survey included, at each site, a sample from a depth of 0 to 5 centimeters, a composite of the soil...

Role of tidal wetland stability in lateral fluxes of particulate organic matter and carbon

Tidal wetland fluxes of particulate organic matter and carbon (POM, POC) are important terms in global budgets but remain poorly constrained. Given the link between sediment fluxes and wetland stability, POM and POC fluxes should also be related to stability. We measured POM and POC fluxes in eight microtidal salt marsh channels, with net POM...
