Abstract

The distribution of naturally occurring radioactive isotopes in the ocean can be used to understand the movement of water and particles through the ocean. Measurements of these same isotopes in ocean sediments can, in turn, be used to reconstruct ocean processes back through time. The objective of this project is to measure the isotope beryllium-10 in samples of seawater, ocean particles, and sediment samples from…
