| Outline of Final Research Achievements |
From sediments collected we have extracted and isolated amino acids and have performed carbon isotope analysis (13C and 14C). These results are revealing carbon isotope patterns in these compounds for the first time and we will interpret and begin to publish the results.

| Academic Significance and Societal Importance of the Research Achievements |
This is the first time the radiocarbon signatures of individual amino acids are revealed in nature. Amino acids are the building blocks of life and their fate in the sedimentary record represents the geological legacy of life on Earth. With radiocarbon we can quantitatively understand this.
