<td class="ecxtext1" bgColor="#eaeaea"><font face="Times New Roman">Studying life
on Earth during the past 3 billion years has led the community of
astrobiologists to an understanding of what type of record Earths
earliest life would have left. Traces of organic carbon, nitrogen, and
sulfur along with the isotopic compositions of these elements are powerful
tools that weve used for these studies. Controversy comes in finding
evidence of life in even older sedimentary rocks-those greater than 3.5
billion years old. Marilyn Fogel and the Carnegie Institution of
Washingtons astrobiology team has studied the characteristics of abiotic
carbon, nitrogen, and sulfur from carbonaceous chondrites, mantle
peridotites, and hydrothermal synthesis experiments in order to understand
the patterns of abiotic organic matter formation so that it can be
distinguished from the remains of biological processes. Fogel will
describe her work studying a Mars analogue environment in Svalbard and
contrast that with recent work on organic matter found in Martian
meteorites. </font></td></tr></tbody></table></center>
