A review of present techniques and methodological advances in analyzing Th-234 in aquatic systems
The short-lived thorium isotope Th-234 (half-life 24.1 days) has been used as a tracer for a variety of transport processes in aquatic systems. Its use as a tracer of oceanic export via sinking particles has stimulated a rapidly increasing number of studies that require analyses of Th-234 in both ma...

The short-lived thorium isotope Th-234 (half-life 24.1 days) has been used as a tracer for a variety of transport processes in aquatic systems.

The original Th-234 method is labor intensive. Thus, there has been a quest for simpler techniques that require smaller sample volumes. Here, we review current methodologies in the collection and analysis of Th-234 from the water column, discuss their individual strengths and weaknesses, and provide an outlook on possible further improvements and future challenges.
