Dissolved thorium and protactinum isotopes (Th-232, Th-230, and Pa-231) were analyzed as core parameters on GEOTRACES cruise transect GA13. This cruise transect focused on known hydrothermal venting sites along the mid-Atlantic ridge of the North Atlantic. The Th/Pa isotopes are excellent tracers of inorganic scavenging (chemical adsorption) onto hydrothermal particualte material and help demonstrate the impact particles can have on scavenging other trace metals of biogeochemical interest. A start-up grant from the University of Southern Missisippi funded the analysis at USM. The cruise was funded by the UK NERC.
