Harmful Algal Blooms in Pennsylvania

The U.S. Geological Survey is collaborating with State and local partners to develop models that provide real-time estimates of Escherichia coli (E. coli) (for pathogens) and (or) microcystin (for freshwater cyanotoxins) levels at Great Lakes beaches and drinking-water intakes.

Geologic Energy Storage

The United States (U.S.) domestic energy supply increasingly relies on natural gas and renewable sources; however, their efficient use is limited by supply and demand constraints. For example, a) in summer, natural gas production may outpace home heating fuel demand and b) in daytime, wind and solar electricity production may outpace industrial power requirements. Storing rather than dumping...

Modeling population dynamics with count data

In this chapter, we describe models of open populations that are subject to change over time due to additions and subtractions. Additions may be in the form of recruitment and immigration, and subtractions may be in the form of mortality, emigration, or both. Conceptually, these models are described by the Birth-Immigration-Death-Emigration (BIDE...

Dynamics of marsh-derived sediments in lagoon-type estuaries

The role of pre-magmatic rifting in shaping a volcanic continental margin: An example from the Eastern North American Margin

Both magmatic and tectonic processes contribute to the formation of volcanic continental margins. Such margins are thought to undergo extension across a narrow zone of lithospheric thinning (~100 km). New observations based on existing and reprocessed data from the Eastern North American Margin contradict this hypothesis. With ~64,000 km...
