Nitrification and nitrous oxide production in the offshore waters of the Eastern Tropical South Pacific
Marine oxygen deficient zones (ODZs) are dynamic areas of microbial nitrogen cycling. Nitrification, the microbial oxidation of ammonia to nitrate, plays multiple roles in the bio…
Structure of pre-monsoon convective systems over a tropical coastal region in southwest India using C-band polarimetric…
The structure of pre-monsoon convective systems over southern peninsular India using polarimetric doppler weather radar (DWR) observations has been analyzed. Convective-stratiform…
Influence of Observational Datasets on ECS and TCR Estimates
Uncertainties in estimates of Equilibrium Climate Sensitivity (ECS) and Transient Climate Response (TCR) are influenced by observational datasets. Variability exists not just amon…
In-situ regolith seismic velocity measurement at the InSight landing site on Mars
InSight’s seismometer package SEIS was placed on the surface of Mars at about 1.2 m distance from the thermal properties instrument HP3 that includes a self-hammering probe. Recor…
Adiabatic temperature profile in the mantle, revised
This study re-evaluates the adiabatic temperature profile of the Earth’s mantle. The global average temperature at the 410-km discontinuity is estimated to be 1805(18) K by compar…
Microplastics, road dust, and biological particles drive hazardous urban ice fog formation
Ice fog is a common form of air pollution that forms at low temperatures and poses extreme hazards for aircraft and automobile travel, particularly in high-latitude environments. …
The Global Conductivity Structure of the Moon
Magnetic sounding is a powerful tool to explore the interior of planetary bodies through the electrical conductivity structure. The electrical conductivity structure of the lunar …
A Late Cretaceous-Eocene Geomagnetic Polarity Time Scale (MM26) that combines marine magnetic anomaly records, radioiso…
The Geomagnetic Polarity Time Scale (GPTS) is essential to date geological events in stratigraphic sequences and to reconstruct plate motions. The first GPTSs were based on the re…
Regime transition in rotating convection driven by inner-core boundary thermochemical coupling
Convection in Earth’s liquid outer core is powered by a combination of thermal and compositional buoyancy released at the inner-core boundary (ICB). The interaction between these …
Can the Moon's Center of Mass–Center of Figure Offset Be Explained With a Uniform Primordial Crust?
A fundamental constraint on the Moon's interior mass distribution is the 1.935-km lunar center of mass (COM)–center of figure (COF) offset. Extant constraints on the mass asymmetr…
Recurrence Quantification Analysis of Volcanic Seismicity: Physically Interpretable Features for Multi-class Event Clas…
Volcano-tectonic (VT), long-period (LP), and hybrid (HB) events arise from distinct source mechanisms but are difficult to classify automatically due to waveform overlap and path …
Seismic Magnitude Variance Consensus Detection Framework: A Six-Criterion Approach for Identifying Critical Earthquake …
We present a six-criterion consensus framework for identifying seismically critical earthquake zones using only standard seismic catalog data. The framework combines three newly d…
1st Adiabatic Invariants and Phase Space Densities for the Jovian Electron and Proton Radiation Belts-Galileo and GIRE3…
The fluxes and phase space densities for a fixed 1 st adiabatic invariant for high energy electrons and protons provide important inputs for various scientific studies for determi…
Preliminary Assessment of PAHs in Soil Near a Coal-Fired Power Plant
Power plants emit particulate matter into the air, making them potentially significant polluters. It includes polycyclic aromatic hydrocarbons (PAHs), which are known legacy pollu…
Modeling ionospheric TEC using gradient boosting based and stacking machine learning techniques
Accurately predicting and modeling the total electron content (TEC) of the ionosphere can greatly improve the accuracy of satellite navigation and positioning and help to correct …
How Clear-Sky Spectral Overlap Shapes Radiation in Cloudy Atmospheres
Optically-thick clouds largely emit thermal radiation at their cloud top temperature across the longwave spectrum. However, the degree to which cloud top temperature dominates out…
Radiation-enhanced fission track annealing revisited and consequences for apatite thermochronometry
Apatite fission track (AFT) analyses for granitoid and metamorphic bedrock samples from the Western Superior Province (Ontario), the Churchill-Rae Province (Melville Peninsula and…
Ambiguous stability of glaciers at bed peaks
Increasing ice flux from glaciers retreating over deepening bed topography has been implicated in the recent acceleration of mass loss from the Greenland and Antarctic ice sheets.…
Hallett-Mossop rime splintering dims the Southern Ocean: New insight from global cloud-resolving simulations
In clouds containing both liquid and ice that have temperatures between -3C and -8C, liquid droplets collide with large ice crystals, freeze, and shatter, producing a plethora of …
Tropical Cyclone Wind Waves in the Gulf of Mexico under a Changing Climate
The expected rise in major tropical cyclones due to climate change will increase their associated hazards, including ocean waves which are the main design parameter for maritime s…
Geomagnetic data from the GOCE satellite mission
The Gravity field and steady-state ocean circulation explorer (GOCE) is part of ESA’s Earth Explorer Program. The satellite carries magnetometers that control the activity of magn…
Ecological Monographs Comment/brief communication Does restoring apex predators to food webs restore ecosystems? Large …
Open Research Statement: This comment uses only previously published sources; no new data was collected.
Automatic Segmentation of Geophysical Trackline Data Applied to Pacific-Rivera Motion
Magnetic trackline data are of central importance in estimating relative plate motions, have allowed a detailed apparent polar wander path to be determined for the Pacific Plate f…
Keeping Coffee and Chocolate on the Table in a Warming World
Despite being global staples and daily comforts for many, coffee and chocolate can only grow in specific regions, making these two crops particularly susceptible to global warming…
Biomarker reconstructions of temperature, salinity, and stratification across glacial-interglacial cycles spanning 240 …
Pleistocene glacial-interglacial climate variability led to cyclical expansion/contraction of the North American ice sheets with corresponding shifts in temperature and hydroclima…
Free-Grid Sediment Budget and Resultant Longshore Transport Distribution on Arbitrary Spatial/Temporal Scales
The concept of a free-grid sediment budget on arbitrary local scales is presented. It is demonstrated that, unlike a traditional sediment budget where the level of detail is predi…
