Black Sea Core

Caption: A visual inspection of the core clearly shows different types of sediment deposited over time. Analysis of the first section (far left), determined the sediment was deposited over the past 2515 years and contained E huxleyi coccoliths. The second core section sediment was deposited 2515-7550 years ago. The last three sections (middle to right) contain calcite-rich, lacustrine or lake-related, sediments dating back 7550-~13,000 years.
