Preparation and Identification of Heavy Minerals for Archaeometrical Studies: Villa of Fiumana (FC), Italy

open access: yesJournal of Raman Spectroscopy, Volume 56, Issue 11, Page 1302-1314, November 2025.
This paper presents a new protocol for the laboratory preparation of archaeological samples. Ceramics that have been hand‐crafted using different sediments as raw materials were collected in a Roman Villa sited in Fiumana (FC), Italy. This method aims at concentrating and analysing heavy minerals in the 15–250 μm grain size fraction, studying the ...

Role of Ocean Circulation in Controlling Zn‐Si Decoupling in the North Pacific

open access: yesGlobal Biogeochemical Cycles, Volume 39, Issue 11, November 2025.
Abstract Zinc (Zn) is biogeochemically important due to its crucial role in biological processes. In the global ocean, there is an apparent coupling between the concentrations of zinc and silicon (Si), and the ratio between their concentrations is nearly constant in the global ocean.

Progressive Oxygenation of the North Atlantic Subpolar Gyre

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 11, November 2025.
Abstract The subpolar North Atlantic (SPNA) is one of the few regions where the deep ocean is in direct contact with the atmosphere, making it a key location for interior ocean ventilation through gas exchange. We use a novel observation‐based data product to analyze large‐scale patterns of the air‐sea flux of oxygen, finding a mean annual flux of 48.1
