Distribution and rare earth element abundances of apatite in Bennu samples determined by synchrotron X‐ray fluorescence spectroscopy

Meteoritics &Planetary Science, EarlyView.
Abstract Apatite is often the most rare earth element (REE)‐enriched mineral in chondritic meteorites. REE enrichment and fractionation levels in apatite grains can give insight into the aqueous fluids in which they formed and the conditions prevailing within the host body. In this study, we applied synchrotron X‐ray fluorescence (SXRF) spectroscopy to

Entering the Era of Directly Supporting Society With Observation‐Based Ocean Acidification Data

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Ocean acidification is a growing concern for many nations around the world. However, our capacity to monitor changes in carbonate chemistry with sufficient spatial and temporal resolution, has until now, been limited, which has impeded effective action and decision‐making at international, national, and regional levels.

A Field Guide to Corralling the Chaos: A Planning Framework for Using Models to Guide Opportunistic Field Studies of Natural Disturbances

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Watersheds regulate biogeochemical processes and provide ecosystem services to human societies, but disturbances can fundamentally alter these processes across space and time. Determining when and where to sample to capture disturbance impacts in watersheds remains a central challenge.

The Consortium for the Advancement of Marine Arctic Science: Breaking the Barriers to Collaboration

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Consortium for the Advancement of Marine Arctic Science (CAMAS) has been created in response to the need for improved capabilities in Earth system modeling, specifically focused on the Arctic marine system. Designed to enable collaborative research, CAMAS has so far carried out a series of 3 hybrid workshops from 2024 to 2026.
