Source: AGU Advances Editors’ Highlights are summaries of recent papers by AGU’s journal editors. The shape of fluvial valleys results from the complex interaction between climate and the local environment. Our current knowledge suggests that river discharge and valley-wall lithology are the main controls on valley width. Yet, current models based on these observations fail […]

The Crust Travels to the Earth’s Core and Back in Record Time
Subduction of continental crust around the Gondwana supercontinent may explain the mantle Dupal anomaly of the southern hemisphere.
Outsourcing the Work of Industrial Climate Science
Climate science is increasingly structured in ways that subcontract repetitive activities to graduate students. Here, early career researchers raise the issue and explore some tradeoffs.
Measuring the Microstructure of Snow from Space
There is more to snow than flakes. Microwave measurements are shown to be capable of illuminating the microstructure of snow in ways that will improve our ability to monitor snow fields from space.
Clumped 18O –18O in Ice Reveals Past Ozone and Wildfire
Reactive gases like ozone are hard to preserve, but clumped isotopes and models provide clues to past ozone and suggest a global increase in wildfire at megafaunal extinction.
Coseismic Displacement of 1987 Earthquake from Aerial Images
Differencing digital surface topography models constructed from historical aerial photographs reveal the coseismic surface displacement field of the 1987 earthquake in northern New Zealand.
Callisto’s H Corona: Offspring of the Surface or the Atmosphere?
The mostly unknown Callisto’s H corona is created by a global tenuous H2 atmosphere and not by surface water as previously believed, providing the first evidence for H2 in Callisto’s atmosphere.
Using Big Data for Monitoring Network Design and Beyond
Large data sets can be generated using deep learning to improve the design of observation networks for monitoring subsurface flow and transport.
New Mechanism for “Giant” Greigite Growth in Deep-Sea Sediments
Understanding greigite formation pathways in sediments is a prerequisite for assessing the marine iron-sulfur-carbon cycle and yield reliable near-syn-sedimentary paleomagnetic records.
Accurate Ocean Tides for Earth System Models
Accurate tide models require self-attraction and loading terms, but can this calculation be done accurately and efficiently for use in global tide and Earth system models?
