Historical changes in phosphorus accumulation in a small lake

Isotopes like 210Pb and 137Cs are effectivetools for determining chronology in lake sediments. Once the chronology is established, environmentalchanges in lakes can be investigated, and the causesfor those changes can often be inferred. 210Pband 137Cs profiles were constructed for thesediments of Crystal Lake, Connecticut, USA. Thegeochronology was used to… CONTINUE READING
