Dataset: Thorium isotope data summaries from R/V Yuzhmorgeologiya, RVIB Nathaniel B. Palmer AMLR2006-Leg1, NBP0606 in the Southern Ocean from January to August 2006 (Ant2006 project, BWZ project)

Thorium isotope data summaries from AMLR and NBP cruises to the Antarctic in 2006

Particulate organic Carbon (POC) flux was determined through measuring Thorium (234Th) reported in dpm/kg .
 

Cruises

AMLR (Antarctic Marine Living Resources) R/V Yuzhmorgeologiya Jan2006:
The research program was focused in the southern Drake Passage
along the Shackelton Shelf located near the Bransfield Strait.
Samples were obtained from the R/V Yuzhmorgeologiya and inflatables
that were taken to island locations.
