The G4Foam Experiment: global climate impacts of regional ocean albedo modification [PDF]
Reducing insolation has been proposed as a geoengineering response to global warming. Here we present the results of climate model simulations of a unique Geoengineering Model Intercomparison Project Testbed experiment to investigate the benefits and ...

Northward shift of the Kuroshio Extension during 1993–2021
The Kuroshio Extension (KE) flows eastward at the northern boundary of the North Pacific subtropical gyre. By transporting large amounts of seawater with heat, the KE contributes significantly to the formation of sea surface temperature (SST) fields ...

Observations of Mesoscale Eddies in Satellite SSS and Inferred Eddy Salt Transport
Observations of sea surface salinity (SSS) from NASA’s Soil Moisture Active-Passive (SMAP) and ESA’s Soil Moisture and Ocean Salinity (SMOS) satellite missions are used to characterize and quantify the contribution of mesoscale eddies to the ocean ...

Ocean’s largest chlorophyll-rich tongue is extending westward (2002–2022)
Upwelling in the Equatorial Pacific nurtures an expansive, westward-stretching chlorophyll-rich tongue (CRT), supporting 18% of the annual global new production. Surrounding the CRT are the oligotrophic subtropical gyres to the north and south, which are

Combining BioGeoChemical-Argo (BGC-Argo) floats and satellite observations for water column estimations of the particulate backscattering coefficient [PDF]
As the second-largest carbon reservoir on Earth, the ocean regulates the carbon balance through dissolved and particulate organic carbon (POC) forms. Monitoring carbon cycle processes is key to understanding the climate system.

Structure and variability of the subtropical gyre [PDF]
Le gyre subtropical est un grand système de courants océaniques et de masses d’eau qui s’étendent sur chacun des océans aux moyennes latitudes. Principalement entraînée par les vents, la circulation océanique proche de la surface a tendance à accumuler des masses d’eau au centre du gyre.

Subtropical gyre variability as seen from satellites
A satellite multi-sensor approach is used to analyse the biological response of open ocean regions of the subtropical gyres to changes in physical forcing. Thirteen years (1998-2010) of SeaWiFS chlorophyll a (Chl-a), combined with concurrent satellite records of sea-surface temperature (SST) and sea level height, were analysed to investigate the ...

The most oligotrophic subtropical zones of the global ocean: similarities and differences in terms of chlorophyll and yellow substance [PDF]
The cores of the subtropical anticyclonic gyres are characterized by their oligotrophic status and minimal chlorophyll concentration, compared to that of the whole ocean. These zones are unambiguously detected by space borne ocean color sensors thanks to

Plastic accumulation in the Mediterranean sea.
Concentrations of floating plastic were measured throughout the Mediterranean Sea to assess whether this basin can be regarded as a great accumulation region of plastic debris.

The global distribution of chromophoric dissolved organic matter (CDOM) in the euphotic layer of the Atlantic, Indian, and Pacific oceans (between 35° N and 40° S) was analyzed by absorption spectroscopy during the Malaspina 2010 circumnavigation ...
