Net primary production from daily cycles of biomass using Argo floats

August 31, 2023

Net primary productivity is a central metric in ocean biogeochemistry that is costly and time-consuming to estimate using traditional water sampling methods. As a result, it is difficult to detect large-scale trends in ocean productivity. While satellite remote-sensing has partially solved this issue, its observations are limited to the top 10 to 40 m of […]

Identifying the water mass composition of a sample has never been so easy!

August 31, 2023

When we collect seawater in any point of the ocean, we are collecting a mix of water masses from different origin that traveled until there keeping their salinity and temperature properties. The Atlantic Ocean is likely the most complex basin in term of water masses containing more than 15 in its depths. Some of them […]

RPiAlk: Balancing Measurement Uncertainty and Accessibility

August 31, 2023

High-accuracy measurement of total alkalinity (TA) is crucial for our understanding of ocean acidification and the inorganic carbon complex. It is also particularly expensive in terms of labor and resources. These barriers limit its application in understudied settings such as inland waters and developing coastal regions. To address this problem, the authors constructed an instrument […]

Unveiling the Hidden Secrets of Ancient Carbon Burial

August 31, 2023

How much carbon has been buried in the depths of our ancient oceans, and how did it shape our planet’s climate? Unraveling this enigma has long eluded researchers, but a recent groundbreaking “bottom-up” study unveils the surprising history of organic carbon burial in marine sediments during the Neogene period. Departing from conventional methods, this study […]

Adaptive emission pathways to stabilize global temperatures

May 11, 2023

Around the world, countries have agreed in the Paris Agreement to limit global warming well below 2°C and to pursue efforts to reduce global warming to 1.5°C. However, large uncertainties remain about which emission pathways will allow us to reach this goal. A recent paper presents a new adaptive approach to create emission pathways and […]

Hydrostatic pressure substantially reduces deep-sea microbial activity

May 11, 2023

Deep sea microbial communities are experiencing increasing hydrostatic pressure with depth. It is known that some deep sea microbes require high hydrostatic pressure for growth, but most measurements of deep-sea microbial activity have been performed under atmospheric pressure conditions. In a recent paper published in Nature Geoscience, the authors used a new device coined ‘In […]

Does dark carbon fixation supply labile DOC to the deep ocean?

March 30, 2023

Nitrifying microbes are the most abundant chemoautotrophs in the dark ocean. Though better known for their role in the nitrogen cycle, they also fix dissolved inorganic carbon (DIC) into biomass and thus play an important role in the global carbon cycle. The release of organic compounds by these microbes may represent an as-yet unaccounted for […]

Enhanced-warming Kuroshio Current experiences rapid seawater acidification and CO2 increase

March 30, 2023

In order to project the future states of the climate and the marine ecosystem it is vital to understand the long-term changes in ocean carbon chemistry driven by anthropogenic influence. A paucity of data make the rates of seawater acidification and partial pressure of CO2 (pCO2) rise on ocean margins highly uncertain. A recent study in Marine Pollution […]
