Andrew Kemp, Ph.D., Assistant Professor, Earth and Ocean Sciences, Tufts University. Dr. Kemp describes the cycles of ocean rise and fall over 2000 years, changes that for most of that time were due to natural forces, and more recently due to human-produced climate change. Dr. Kemp's research focus is on reconstructions of sea-level change over the last 2000 years. To produce an accurate record of a very dynamic process over thousands of years, he combines factors such as salt marsh fossil records, sediments and other indicators that he will explain. We learn how this precise reconstruction uncovers past geological and oceanographic history and how this record is used to help predict the scope of present and future sea level rise.
