Multi-element neutron activation analysis measurements towards the geochemistry of particulate matter exchange between continent—Atmosphere—Ocean

Abstract

Sampling of marine aerosol and ocean water particulate matter yields very small quantities of material. INAA is used for routine analysis since it provides measurements of as many as 25 elements and permits multiple use of the small samples. Results are given for the mean elemental composition of Atlantic marine aerosols and oceanic suspended matter. Such analyses are essential for the interpretation of global geochemical cycles.
