This research will study                                                   (identify and enumerate) diatoms in                                             the Sirius Formation and age-                                                   equivalent and related sediments                                                collected on various parts of                                                   Antarctica with the following                                                   objectives in mind:                                                                  1.  A relatively high                                                      resolution stratigraphy will place                                              age constraints upon each sample.                                               These data will allow such topics                                               as the timing of late Neogene                                                   deglaciation and reglaciation of                                                Antarctica, glacial overriding                                                  events and the deposition of non-                                               ice related sediments.                                                               2.  The diatoms found in the                                               tills and other Neogene sediment                                                from the Antarctic continent impose                                             some constraints on our                                                         paleoenvironmental interpretation of                                            this region and the surrounding                                                 Southern Ocean.  Because many of the                                            species found in these sediments are                                            extant, diatoms can be used to                                                  characterize the paleotemperature                                               and paleoclimate regime around the                                              continent, particularly for the                                                 middle to late Pliocene.  Since                                                 this time interval covers the                                                   prelude to, and inception of,                                                   northern hemisphere glaciation,                                                 these data will draw Antarctica                                                 into the discussion of events                                                   leading up to the Quaternary                                                    climatic deterioration.
