Brine Pool Microbes Enrich Metalliferous Sediments in Salt Giant Basins

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract We report the discovery of an extinct deep‐sea brine pool in the Red Sea's Hume Deep, providing evidence that rift‐shoulder pools are ephemeral on millennial timescales, and that the microbially‐enriched metalliferous deposits produced during the pool's active phase persist into the stratigraphic record.

Calcareous Benthic Foraminifera Under Ocean Alkalinity Enhancement: Synthesis, Knowledge Gaps, and Future Research Agenda

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Limiting global warming to 1.5°C will require carbon dioxide removal, and Ocean Alkalinity Enhancement (OAE) is increasingly being explored as a marine carbon dioxide removal pathway. However, benthic biological responses remain much less constrained than water‐column processes and planktonic responses, even though calcareous benthic ...

Origin of the unusually strong and selective binding of vanadium by polyamidoximes in seawater

Nature Communications, 2017
Amidoxime-functionalized polymeric adsorbents are the most promising materials for harvesting uranium from seawater. Here the authors investigate the preferential extraction of vanadium over uranium by polyamidoximes by exploring the unusually strong and
