Abstract

Particle-bound Th-234 measurements and C:234Th ratios for particles (seston) collected during the 2012-2013 field season of the Palmer LTER program near Anvers Island in the Western Antarctic Peninsula. Particle-bound Th-234 is a useful tracer for particle scavenging and sinking processes in the ocean. Vertical profiles of particle-bound Th-234 and C:234Th ratios were measured approximately weekly. Measurements typically spanned from the surface to a depth of 65 m.
