Radium Isotopes
Environmental changes in the Arctic Ocean are occurring now!
This is what reveals the first full transarctic section of radium-228 (228Ra) in surface waters measured during Arctic cruises along GEOTRACES transects GN04 (cruise PS94) and GN01 (cruise HLY1502) proposed […]

Revelations from the dissolved 226Ra-228Ra pair distribution in the South East Pacific Ocean
While it is confirmed that radium-226 (226Ra) is an interesting tracer of the water masses encountered along the GP16 US East Pacific Zonal Transect (EPZT) section cruise, 228Ra data coupled […]

Climate change induced spectacular increase of the land-ocean inputs in the Arctic Ocean
Measurements of radium-228 (228Ra) in the framework of the 2015 U.S. GEOTRACES Arctic Transect (GN01), revealed that the surface water content of this tracer has almost doubled over the last […]

Radium quartet reveals no less than four main processes along the GEOTRACES North Atlantic Ocean section (30°N)
The four radium (Ra) isotopes (224Ra, 223Ra, 228Ra, 226Ra, “radium quartet”) are produced in situ via decay of their insoluble thorium isotope parents in sediments from the continental margins and […]
