Intercalibrated lead concentration measurements in the Atlantic Ocean

Measurements of dissolved (< 0.22 mum) lead concentrations in seawater in s amples collected on the third 1996 Intergovernmental Oceanographic Commissi on cruise (IOC III) in the Atlantic Ocean have been intercalibrated. This r epresents the first successful intercalibration (p < 0.05, paired t-test) o f lead concentration measurements in the IOC's Global Investigation of Poll ution in the Marine Environment (GIPME), which was designed to establish th e baseline concentrations of trace elements in oceanic waters and the repro ducibility of those measurements.
