- •
Thorium and particle data measured using settling velocity sediment traps were used in this study.
- •
A “two-layer” model was built to describe thorium particle interactions.
- •
Maximum likelihood method was applied to estimate particle thorium reaction rate constants.
- •
Source and sink terms for 234Th and 230Th were clearly defined.
