Service DHI offers dating of sediment cores by means of the 210Pb method and may assist with sampling in both marine and freshwater systems.
The sediment samples must remain totally undisturbed during sampling to obtain the best possible dating.
GECSC researchers conduct multi-purpose geologic mapping and topical scientific studies to address issues concerning geologic, climatic, ecosystem, and land surface changes; human interactions with the environment; and physical, chemical, and biological characterization of the Earth's surface and upper crust.

In the water phase 210Pb is adsorbed to particulate matter and together they are deposited in the sediment. The remaining amount of 210Pb at a certain depth will reveal the age of the given sediment layer.
