Mapping riverine habitats of the Delaware River using bathymetric LiDAR

Ecosystem management and assessment of rivers requires detailed data on bathymetry before estimates of aquatic habitats can be determined. However, mapping bathymetry in shallow rivers is challenging due to river depth limitations for watercraft.  Light detection and ranging (LiDAR) technology has revolutionized aerial mapping of topography and vegetation, but the infrared lasers used on these...

Assessing stream health and fish habitat in streams of the Chesapeake Bay Watershed

Streams and rivers provide habitat for a diverse array of aquatic and semi-aquatic species. However, human alteration to landscapes and riverscapes has affected this habitat resulting in its degradation and thus loss of habitat and associated sensitive aquatic species.  While this relationship has been known for many years, only recently has the availability of data and analytical capabilities...

Exploring the potential effects of shale oil and gas development on freshwaters

Widespread shale oil and gas (unconventional oil and gas, UOG) has only recently begun and many gaps in our knowledge of its potential effects to freshwaters exist. We conducted several studies aimed at filling these gaps, providing data on the rates and volumes of materials spilled, proximity of spills to important ecosystems, and overall production of wastes.

Estimating the impact of seep methane oxidation on ocean pH and dissolved inorganic radiocarbon along the U.S. mid‐Atlantic Bight

Ongoing ocean warming can release methane (CH4) currently stored in ocean sediments as free gas and gas hydrates. Once dissolved in ocean waters, this CH4 can be oxidized to carbon dioxide (CO2). While it has been hypothesized that the CO2 produced from aerobic CH4 oxidation could enhance ocean acidification, a previous study...

Seismic anisotropy measurements show that upper mantle hydration at the Middle America Trench (MAT) is limited to serpentinization and/or water in fault zones, rather than distributed uniformly. Subduction of hydrated oceanic lithosphere recycles water back into the deep mantle, drives arc volcanism, and affects seismicity at subduction zones....
