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

Radium and Thorium isotope data summaries from AMLR and NBP cruises to the Antarctic in 2006 Naturally occurring radium isotopes (224Ra, 226Ra, 228Ra) were used in determining lateral mixing processes which are reported in dpm/m3. Particulate organic Carbon (POC) flux was determined through measuring Thorium (234Th) reported in dpm/kg.

Cruises
AMLR (Antarctic Marine Living Resources) R/V Yuzhmorgeologiya Jan/2006:
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.
