Mixing Accounts for More Than Half of Biogeochemical Changes Along Mode Water Ventilation Pathways Open
Mode waters are critical for ocean ventilation and carbon sequestration. Using observations, we trace their subduction pathways and biogeochemical evolution. Solving modified mixing equations that account for respiration reveals that less …

Machine Learning‐Based Clustering of Oceanic Lagrangian Particles: Identification of the Main Pathways of the Labrador Current Open
Modeled geospatial Lagrangian trajectories are widely used in Earth Science, including in oceanography, atmospheric science and marine biology. The typically large size of these data sets makes them arduous to analyze, and their underlying…

Can green hydrogen production be used to mitigate ocean deoxygenation? A scenario from the Gulf of St. Lawrence Open
Ocean deoxygenation and expansion and intensification of hypoxia in the ocean are a major, growing threat to marine ecosystems. Measures currently used to protect marine biodiversity (e.g., marine protected areas) are ineffective in counte…

Temporal and spatial evolution of bottom-water hypoxia in the St Lawrence estuarine system Open
Persistent hypoxic bottom waters have developed in the Lower St Lawrence Estuary (LSLE) and have impacted fish and benthic species distributions. Minimum dissolved oxygen concentrations decreased from ∼ 125 µmol L−1 (38 % saturation) in th…

Remote control of the retroflection of the Labrador Current Open
The Labrador Current carries cold, relatively fresh, and well-oxygenated waters into the subpolar North Atlantic and into the Slope Sea. The relative contribution of these waters to either region depends on the eastward retroflection of th…

Unsupervised clustering of Lagrangian trajectories in the Labrador Current Open
<p>Lagrangian studies are a widely-used and powerful way to analyse and interpret phenomenons in oceanography and atmospheric sciences. Such studies can be based on dataset either consisting of real trajectories (e.g. oceanic drifter…

Variability of the circulation in the western North Atlantic and its impact on deep-water oxygen concentrations in the St. Lawrence Estuary on the western continental shelf: evidence from observations Open
<p>Oxygen concentrations in the deep waters of the Lower St. Lawrence Estuary, in eastern Canada, have decreased by 50% over the past century, reaching hypoxic levels. To study the causes of this deoxygenation, we applied a mixing mo…
