Uses of radioactive dating
Ocean sediment C-14 data The Lamont-Doherty Earth Observatory of Columbia University has compiled 974 C-14 dates from 309 ocean sediments cores, covering the period from 40,000 years BP to the present worldwide. The USGS Bear Lake Project aims to create records of past climate change for the Bear Lake region,including changes in precipitation patterns during the last 10,000 years and how the size of Bear Lake has varied in the past, to assess the possibility of future flooding and drought.
It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself.
It can be used on objects as old as about 62,000 years.
