Ocean Circulation Modulating the Nutrient Distribution and Fluxes at Regional and Fine Scales: A Case Study in the Northwestern Mediterranean Sea

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract In the oligotrophic ocean, nutrient distribution plays a key role in controlling primary production via upward fluxes. In spring 2023, the BioSWOT‐Med cruise investigated how fine‐scale ocean dynamics influence nutrient availability in the Mediterranean Sea.

Barium Isotopes Indicate Spatiotemporal Heterogeneity of Marine Primary Productivity During the Toarcian Oceanic Anoxic Event

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Toarcian Oceanic Anoxic Event (T‐OAE, ∼183 Ma) was characterized by globally enhanced organic‐carbon burial and a negative carbon‐isotope excursion (N‐CIE). However, the role of marine productivity at this time, and its spatiotemporal variability, is unclear.
