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,...

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....
