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.
Relative dating stems from the idea that something is younger or older relative to something else.
In a stratigraphical context objects closer to the surface are more recent in time relative to items deeper in the ground.
More recently is the radiocarbon date of 1950 AD or before present, BP.
There are two techniques for dating in archaeological sites: relative and absolute dating.
The radiocarbon method is applied in many different scientific fields, including archeology, geology, oceanography, hydrology, atmospheric science, and paleoclimatology.
