Lodge moraines: a common yet underreported end‐moraine type—a review

Boreas, EarlyView.
Lodge moraines are a distinct genetic type of end moraine formed by submarginal accretion of subglacial till; they are some of the largest end moraines in the world. Although underreported in the literature, they are of equal importance to push, dump and hummocky end moraines. End moraines are formed at glacier ice margins and show the extent of former

Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer

Boreas, EarlyView.
Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

The Effect of Mine‐Related Groundwater Use and Management on Surface Water in the Middle Humboldt River Basin

Groundwater, EarlyView.
Abstract The Humboldt River, in Northern Nevada, USA, is a source of water for agricultural, municipal, and industrial uses. Mining has been active in Nevada since the 1800s. The recognition that groundwater withdrawal for many purposes—including mining—has the potential to deplete streamflow has prompted studies of the Humboldt River Basin.

Demonstration of a High‐Resolution Passive Profiler for Characterizing the Distribution of PFAS in Groundwater: A Comparison of Methods in the Field

Groundwater Monitoring &Remediation, EarlyView.
Abstract Characterizing the concentration and mass flux spatial distributions at sites with complex hydrogeologic conditions is critical to evaluate the fate and transport of contaminants, as well as to design effective remediation programs. PFAS (per‐ and polyfluoroalkyl substances)‐contaminated sites are even more complex due to the large number of ...
