Arc Heat Flow and Magmatic Heat Budgets

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

Protracted High‐Grade Metamorphism and Slow Cooling in the Adirondacks Recalibrate Neoproterozoic Global Paleogeography

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The assembly and breakup of the supercontinent Rodinia set the stage for Earth system evolution through the Neoproterozoic Era. Laurentia, the central craton in Rodinia, lacks well‐dated paleomagnetic poles between ca. 990 Ma and 780 Ma. In this study, we develop new U‐Pb petrochronology and thermochronology data sets from zircon, garnet ...

CAMSS: A spectroscopic survey of meteoroid elemental abundances

, 2014
International audienceThe main element abundances (Mg, Fe, Na, ...) of some Near Earth Objects can be measured by meteor spectroscopy. The Cameras for All-sky Meteor Surveillance (CAMS) Spectrograph project aims to scale up meteor spectroscopy in the ...

Unsupervised Deep Representation Learning for Infrasound Phase Identification

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Infrasound phase identification is challenging because atmospheric variability strongly influences signal propagation on short timescales that are not resolved by standard atmospheric models. While traditional approaches rely on propagation modeling and array‐derived parameters, recent work suggests that waveform structure itself encodes ...

Late Jurassic Carbon Isotope Excursion (Middle Oxfordian Event) Paces With Astronomical Forcing in the Northwestern Tethys

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Marine carbonate carbon isotopes (δ13C), over orbital to multi‐million‐year timescales, provide critical insight into the carbon cycle connecting Earth's atmosphere, lithosphere, hydrosphere and biosphere. However, the influence of astronomical forcing on deep time carbon cycle dynamics remains poorly constrained.

What Observations Would an Energetic Neutral Atom Imager Have Made During the Voyager 2 Flyby of Uranus?

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

Impacts of E‐Region Neutral Wind Shear on Equatorial Plasma Bubbles: SAMI3 Simulations Including Metal Ions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The vertical shear of horizontal neutral winds plays an important role in forming dense metallic layers in the E region. Previous studies suggest that metal ion layers may inhibit equatorial plasma bubble (EPB) development by enhancing E‐region Pedersen conductivity.

Effects of Comet Encke's Meteoroid Stream on the Seasonal Variation of Mercury's Ca Exosphere

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Mercury's calcium (Ca) exosphere, observed by NASA's MESSENGER mission, exhibits high temperatures (>50000 K) and pronounced seasonal variability, with its source mainly on the dawn side. Enhanced Ca emission near True Anomaly Angle (TAA) ∼25° and ∼150° has been attributed to Comet 2P/Encke meteoroid streams.

Long‐Term Deformation in the Alpine‐Provence Foreland Constrained by In Situ Calcite U‐Pb Dating

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The evolution of the Alpine‐Provence foreland is characterized by multiple deformation phases since the Mesozoic, representing successive compressional and extensional episodes. The precise timing and spatial evolution of these deformation phases remain poorly constrained due to the lack of absolute geochronological data. Here, we present U–Pb

Provider Perceptions of Perinatal Mental Healthcare Access

Birth, Volume 53, Issue 2, Page 341-349, June 2026.
Study methodology and conclusions: Primary barriers to care and action items for providers. ABSTRACT Background The consequences of untreated perinatal mental health conditions are well‐established, yet fewer than one in five women experiencing perinatal mental health distress receive treatment. Although recommendations for evidence‐based treatment are
