Quantifying estuarine bathymetric changes under sea-level cycles: Insights from a moving boundary framework
Estuaries are dynamic coastal features that support industry, food production, and recreation, and provide habitat for numerous animal species. Their typically low surface gradien…
Standardized daily high-resolution large-eddy simulations of the Arctic boundary layer and clouds during the complete M…
This study utilizes the wealth of observational data collected during the recent MOSAiC drift experiment to constrain and evaluate 190 daily Large-Eddy Simulations (LES) of Arctic…
Electromagnetic Detection of ELF/VLF Signals Emitted by Geminids 2017 Meteors
Skywatchers have been fascinated by ’meteors’ radiant glow for years. Early reports show that the sounds of these luminous meteors have been recorded, a rare occurrence due to ’so…
A flow-curvature-based model for channel meandering in tidal marshes
Channel meandering is ubiquitous in tidal marshes, yet it is either omitted or weakly implemented in morphodynamic models. Here we propose a novel numerical method to simulate cha…
Reducing Flood Insurance Costs by Employing Geographic Risk Complementarity
Flood insurance is an important financial measure for flood risk management. However, a significant protection gap in flood insurance exists in many countries due to high flood in…
Physics-Informed Neural Networks for Estimating a Continuous Form of the Soil Water Retention Curve from Basic Soil Pro…
The soil water retention curve (SWRC) is essential for describing water and energy exchange processes at the interface between the solid earth and the atmosphere. Despite its impo…
EMM EMUS Observations of FUV Aurora on Mars: Dependence on Magnetic Topology, Local Time, and Season
We present a comprehensive study of the nightside aurora phenomenon on Mars, utilizing observations from EMUS onboard EMM. The oxygen emission at 130.4 nm is by far the brightest …
Assessment of Forced Evaporation as a Solution for Onsite Produced Water Management
As a net water production entity where unconventional oil and gas extraction operations generate volumes of hypersaline water (known as produced water, PW) greater than they consu…
Vertical mixing and light penetration regulate timing of seasonal algae blooms in a small temperate lake
Many temperate lakes accumulate sediment derived orthophosphate (PO4) in their hypolimnion during late-summer deep-water hypoxia. In dimictic lakes, fall turnover will mix the PO4…
Understanding Full-Depth Steric Sea Level Change in the Southwest Pacific Basin using Deep Argo
Using nine years of full-depth profiles from 55 Deep Argo floats in the Southwest Pacific Basin collected between 2014 and 2023, we find consistent warm anomalies compared to a lo…
Dust Source Areas and Their Plume Extent Derived from Satellite Data Fields
In this study, prominent dust source areas are identified along with their plume extent using high temporal frequency satellite observations. Hourly dust plume observations of the…
A Physics-Enhanced Neural Network for Estimating Longitudinal Dispersion Coefficient and Average Solute Transport Veloc…
Dispersion coefficients and the average solute transport velocity are pivotal for groundwater solute transport modeling. Accurately and efficiently determining these parameters is…
First Time-Resolved Leader Spectra associated with a Downward Terrestrial Gamma-Ray Flash detected at the Telescope Arr…
Optical emissions associated with Terrestrial Gamma-ray Flashes (TGFs) have recently become important subjects in space-based and ground-based observations since these emissions p…
Characteristics of Convectively Induced Turbulence in East Asia Using Geostationary Korea Multi-Purpose Satellite-2A (G…
Deep convection and its vicinity are important areas of turbulence encounters in cruising aircraft, called convectively induced turbulence (CIT). In this study, deep convection ar…
Effects of the estimated inversion strength and aerosols on monthly variations of subtropical marine stratocumulus to t…
Satellite and reanalysis data over 20years (2003-2022) are used to study how the estimated inversion strength (EIS), other known thermodynamic variables, dust aerosols (DAs) and b…
Abrupt Changes in the Timing and Magnitude of the North Atlantic Bloom Over the 21st Century
The North Atlantic subpolar gyre is a key region for the North Atlantic phytoplankton bloom (NAB), the foundation of the regional foodweb. The NAB is dependent on nutrients season…
Simple-to-complex crater transition for the Uranian satellites Ariel and Miranda
The latest decadal survey identified the Uranus system as the highest-priority new target for a NASA Flagship mission. Ariel and Miranda are potential ocean worlds with evidence o…
COMPARING ROBUST OPTIMIZATION APPROACHES FOR ADDRESSING HYDROLOGIC MODEL UNCERTAINTY IN INFRASTRUCTURE PLANNING: A GREE…
Water resources planning depends upon hydrologic models to estimate flows and storage under candidate engineering designs. However, such models are calibrated with limited flow da…
Geologic exploration activities increase methane emissions from boreal peatlands
Boreal peatlands serve as long-term carbon (C) sinks as well as a significant source of methane (CH4) to the atmosphere. However, peatlands are threatened by both natural and anth…
Hydrologically informed estimation of plant species richness across a vernal pool complex using drone-mounted LiDAR
Understanding the spatial patterns of plant diversity across vernal pool complexes remains challenging, as plant communities change rapidly in time and concurrent collection of re…
Strain localization and deformation mechanisms in melt-/fluid-bearing UHP eclogites: Implications for exhumation dynami…
Melt/fluid evolution processes are important in determining the rheological behavior of lithosphere subducted to and exhumed from ultrahigh-pressure (UHP), controlling the flow of…
Dam reoperation to mitigate changing climate extremes in the Omo River valley
Climate change is projected to increase the intensity and frequency of extremes in river basins around the world. Water infrastructure such as reservoirs are often used to buffer …
The Quantified Galloway Ternary Diagram of Delta Morphology
Waves, rivers, and tides shape delta morphology. Recent studies have enabled predictions of their relative influence on deltas globally, but methods and associated uncertainties h…
Two-Streams Revisited: General Equations, Exact Coefficients, and Optimized Closures
Two-Stream Equations are the most parsimonious general models for radiative flux transfer with one equation to model each of upward and downward fluxes; these are coupled due to t…
The Averaged Hydrostatic Boussinesq Equations in Generalized Vertical Coordinates
Due to their limited resolution, numerical ocean models need to be interpreted as representing filtered or averaged equations. How to interpret models in terms of formally average…
Machine learning classification strategy to improve streamflow estimates in diverse river basins in the Colorado River …
Streamflow in the Colorado River Basin is significantly altered by human activities including land use/cover alterations, reservoir operation, irrigation, and water exports. Clima…
Spatial and Temporal Heterogeneity of Martian Tropical Water Ice Through Analysis of Radial and Layered Ejecta Craters
Martian layered ejecta craters are theorized to form by tapping into water ice. The inference that some equatorial layered ejecta craters are Amazonian indicates ice has persisted…
Future decline of Antarctic Circumpolar Current due to polar ocean freshening
The Antarctic Circumpolar Current is the world’s strongest ocean current. This vast current system is linked to ocean overturning and is pivotal to the uptake of ocean heat and CO…
