Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

Boreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Phylogenetic and ecological duality in the otoliths of Sciaenidae

Cladistics, EarlyView.
Abstract Teleost fishes have evolved taxon‐specific otoliths that vary greatly in size and shape and are primarily involved in hearing and balance. This study identifies the main drivers of otolith shape disparity in Sciaenidae, a clade of sound‐producing bony fishes, using three‐dimensional geometric morphometrics (3DGM).

The G.I. Bill and underemployment

Contemporary Economic Policy, EarlyView.
Abstract Recent veteran college graduates report experiencing high levels of underemployment, which have a negative impact on their well‐being and hinder their successful transition to civilian life. This paper quantifies the scope of this problem by estimating the impact of World War II, Vietnam War, and Post‐9/11 G.I.

Enhancing Recharge in the Edwards Aquifer, Texas: Measures, Outcomes, and Lessons for Karst Aquifers

Groundwater, EarlyView.
Abstract Managed aquifer recharge is a widely adopted method that involves storing excess water underground for future use. While managed aquifer recharge has been applied globally to different aquifer types, its use in karst aquifers is less common due to the unique hydrogeological characteristics of these systems, including high permeability ...

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.

Impact of River Morphology on River–Groundwater Exchange in Braided River Systems

Groundwater, EarlyView.
Abstract Braided river systems are an important source for groundwater recharge, but their complex morphology makes river–groundwater exchange fluxes difficult to estimate. Their river channel morphology changes frequently after floods, which has effects on recharge rates that have rarely been studied in the past.
