On the Measurement of Ocean Acidity With Ambient Sound

Journal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract The volume‐integrated pH of seawater can be determined from the frequency and depth dependence of wind‐generated ambient noise in the ocean. Over the 1–10 kHz frequency band, three main processes contribute to the acoustic attenuation in seawater: the chemical relaxation of boric acid and magnesium carbonate (<3 kHz, related to pH) and of ...

Tidal Evolution of Exoplanets

, 2010
Tidal effects arise from differential and inelastic deformation of a planet by a perturbing body. The continuous action of tides modify the rotation of the planet together with its orbit until an equilibrium situation is reached. It is often believed that synchronous motion is the most probable outcome of the tidal evolution process, since synchronous ...

Ancient Mars Climate With a Polar Ocean and Ice Sheet Dynamics

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract In this article, we study the conditions required to maintain a stable ocean on Mars 3 Ga using a new suite of simulations. These simulations couple a 3D Global Climate Model with ocean dynamics and ice sheet flow. The model includes the main processes of the atmosphere/hydrosphere/cryosphere to investigate Mars' ancient climate.

DYNAMIC EVOLUTION EXOPLANET SYSTEMS, MOVING IN ORBITAL RESONANCES WITH THE ACCOUNT OF SECULAR PERTURBATION FROM N BODIES

Odessa Astronomical Publications, 2017
Equations of exoplanet's motion connected with orbital Lindblad resonances with the account of secular terms caused by gravitational non-resonant perturbation are derived. Qualitative researches of orbital evolution modeling exoplanet systems are carried

Electrical Resistivity of Liquid Fe‐16S‐2Si up to 13 GPa With Implications for the Adiabatic Heat Flux Through the Core of Exoplanet TRAPPIST‐1h

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Thermal convective processes in the liquid cores of terrestrial planetary bodies with the capacity to generate magnetic dynamos may be better characterized by thermal conductivity estimates of core conditions. The composition of the core of asteroid 4 Vesta as determined by geochemical studies of HED meteorites is used as an analog for the ...

OnAIR: Applications of the NASA on‐board artificial intelligence research platform

AI Magazine, Volume 46, Issue 3, Fall 2025.
Abstract Infusing artificial intelligence algorithms into production aerospace systems can be challenging due to costs, timelines, and a risk‐averse industry. We introduce the Onboard Artificial Intelligence Research (OnAIR) platform, an open‐source software pipeline and cognitive architecture tool that enables full life cycle AI research for on‐board ...

Re‐Analysis of Pioneer Venus Data: Water, Iron Sulfate, and Sulfuric Acid are Major Components in Venus' Aerosols

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract We present a new and transformative composition for Venus' cloud aerosols using previously uncharacterized data acquired by the Pioneer Venus Large Probe, which descended through Venus' atmosphere in 1978. This aerosol composition was extracted by re‐analyzing data acquired by the Large Probe Neutral Mass Spectrometer (LNMS) and re‐evaluating ...

The “Analogs for VENus' GEologically Recent Surfaces” (AVENGERS) Initiative: Using Terrestrial Analogs to Study Recent Volcano‐Tectonic Activity on Venus and Inform the Characterization of Terrestrial Exoplanets

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Several missions to Venus have recently been selected for launch, opening a new era for the exploration of the planet. A key question these missions seek to address is whether Venus is geologically active today. Detecting active volcanism on Venus would contribute to a better understanding of volcanic and atmospheric processes on Earth.
