Topography, management, and extreme precipitation influence greenhouse gas emissions in a cool, humid corn silage system

open access: yesJournal of Environmental Quality, Volume 55, Issue 3, May/June 2026.
Abstract Agricultural soils are sources of nitrous oxide (N2O) and, under prolonged saturation, methane (CH4)—two potent greenhouse gases (GHGs). Soil management, field topography, and climate all influence GHG emissions, yet their interactions are not well understood.

An autonomous and economical benthic incubation chamber for measuring dissolved oxygen fluxes in shallow, low‐flow environments

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract Benthic incubation chambers enclose a known volume of water overlying a known area to measure water chemistry changes and are typically used to quantify the metabolic activity of benthic organisms or communities. Here we present an economical benthic incubation chamber for shallow, low‐flow environments, built using off‐the‐shelf components ...

The Roles of Climate and Tectonics in the Tectonomorphic Evolution of the Sagarmatha (Mt. Everest) Region, Eastern Nepal Himalaya

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract To understand the interplay of climate and tectonics in driving long‐term erosion and landscape evolution in the Himalayan orogen, this study examines the tectono‐thermal evolution of the Sagarmatha (Mt. Everest)‐Rolwaling‐Okhaldhunga region in eastern Nepal.
