The technique used is called carbon dating and in this lesson we will learn what this is and how it is used. Carbon dating, or radiocarbon dating, is a method used to date materials that once exchanged carbon dioxide with the atmosphere. In the late 1940s, an American physical chemist named Willard Libby first developed a method to measure radioactivity of carbon-14, a radioactive isotope.

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.

Carbon dioxide in the atmosphere contains a constant amount of carbon-14, and as long as an organism is living, the amount of carbon-14 inside it is the same as the atmosphere.Here you can publish your research papers, essays, letters, stories, poetries, biographies, notes, reviews, advises and allied information with a single vision to liberate knowledge.
