Abstract

Seafloor sediments hold histories of certain processes occurring on land and in the ocean. Radioisotopes can be used as tracers to study some of these histories—for example, the history of how rapidly sediment accumulates on the seafloor or the history of contaminants released into the environment. Interestingly, these two examples can be used together because of nuclear proliferation during the mid-1900s. During…
