A current synthesis on the effects of electric and magnetic fields emitted by submarine power cables on invertebrates

Abstract The goal of clean renewable energy production has promoted the large-scale deployment of marine renewable energy devices, and their associated submarine cable network. Power cables produce both electric and magnetic fields that raise environmental concerns as many marine organisms have magneto and electroreception abilities used for vital purposes. Magnetic and electric fields’ intensities decrease […]

Radiolarians and the silicon cycle: Natalia Llopis-Monferrer’s work in the spotlight!

The American Geophysical Union (AGU) has declared “Research Spotlight” the recent article by Natalia Llopis-Monferrer in “Global Biogeochemical Cycles” on the importance of radiolarians (marine planktonic organisms) in the silicon cycle of the world ocean. This recent work re-evaluates the role of these tiny protists, which could contribute up to one-fifth of the world’s silica […]

Bivalve δ15N isoscapes provide a baseline for urban nitrogen footprint at the edge of a World Heritage coral reef

Abstract Eutrophication is a major threat to world’s coral reefs. Here, we mapped the distribution of the anthropogenic nitrogen footprint around Nouméa, a coastal city surrounded by 15,743 km2 of UNESCO listed reefs. We measured the δ15N signature of 348 long-lived benthic bivalves from 12 species at 27 sites and interpolated these to generate a […]

The TONGA mission

David Gonzalez Santana and Géraldine Sarthou from the Chibido team are on board the R/V Atalante in the South Pacific for the TONGA cruise (PIs Sophie Bonnet (MIO) and Cécile Guieu (LOV), + link on the CHIBIDO team website). The objective of TONGA is to study the inputs of trace elements from shallow hydrothermal sources […]
