Trace Elements in Total Atmospheric Deposition Directly Measured Over the Caribbean Region: Natural Versus Anthropogenic Sources and Geographic Origin

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Dust, sea salt, and anthropogenic and biogenic particles in total atmospheric deposition are sources of essential elements that can significantly impact biogeochemical cycles in the Atlantic Ocean and in islands of the Caribbean region. This unique 41‐month data set records direct sampling of total atmospheric deposition from March 2015 to ...

Bulk Hydrogen Isotopes in Ordinary Chondrites

, 2023
Bulk hydrogen isotopes in nominally anhydrous meteorites are a key component in our understanding of the distribution of hydrogen in our solar system, including the provenance of water on the Earth.

Color electron microprobe cathodoluminescence of Bishunpur meteorite compared with the traditional optical microscopy method

REM: International Engineering Journal
Cathodoluminescence (CL) imaging is an outstanding method for sub classification of Unequilibrated Ordinary Chondrites (UOC) - petrological type 3. CL can be obtained by several electron beam apparatuses.

Mössbauer Study of Weathering Products in Meteorites from the Atacama Desert

Magnetochemistry
During their stay at the surface of the Earth, meteorites undergo terrestrial weathering. In particular, the iron-nickel alloys and iron sulfides that are abundant in many types of meteorites transform into oxides and oxihydroxides (magnetite, maghemite,

Mössbauer studies of three ordinary chondrites type H and three ordinary chondrites type LL – uncertainty of the determination of spectral areas [PDF]

, 2019
Mössbauer 57Fe measurements of three ordinary chondrites type H and of three ordinary chondrites type LL were performed at room temperature. The spectral areas were fitted using the “Recoil” program (Lagarec i in. 1998).

Puffy Venuses: The Mass–Radius Impact of Carbon-rich Atmospheres on Lava Worlds

The Astrophysical Journal
The recent advancements in exoplanet observations enable the potential detection of exo-Venuses, rocky planets with carbon-rich atmospheres. How extended these atmospheres can be, given high carbon abundances, has not been studied.
