Impacts of coastal and watershed changes on upper estuaries: causes and implications of wetland ecosystem transitions along the US Atlantic and Gulf Coasts

Estuaries and their surrounding wetlands are coastal transition zones where freshwater rivers meet tidal seawater.  As sea levels rise, tidal forces move saltier water farther upstream, extending into freshwater wetland areas. Human changes to the surrounding landscape may amplify the effects of this tidal extension, impacting the resiliency and function of the upper estuarine wetlands. One...

Arsenic variability in water-supply wells

The USGS, in cooperation with the Town of Seabrook, New Hampshire and a private well owner, is assessing the variability of arsenic over multiple time scales. A network of three wells is being used to monitor changes in arsenic, arsenic species, a host of other chemical constituents, and the distribution of ages of groundwater entering the wells. The wells—one domestic bedrock aquifer well,...

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...
