Annual Report 2012 of the Working Group on Paleogene Stratigraphy of the North Pacific

In 2012 the Working Group on North Pacific Paleogene continued its activities .
1. New materials on the Paleocene-Eocene development of the Kamchatka-Sachalin region have been prepared for press. Attention was specially payed to evolution of biotic assemblages in changing paleogeographic environments, particularly climate. The materials will be presented in a special monograph and a number of articles.
2. The Working Group met in St.Petersburg in April 2012, where a plan of activities for 2013-2015 was considered. It was noted that there was an urgent need of publication of paleontological material (mollusks and foraminifers) from the Kamchatka Paleogene sections studied.
3. At 34 IGC, Australia, August 2012 some members of the WG made presentations on the North Pacific Paleogene problems ( Gladenkov A. Marine planktic diatoms of the Earliest Oligocene: northern high latitudes versus southern high latitudes; Gladenkov Y. Paleogene and Neogene climatic fluctuations in the North Pacific: biotic evolution and paleogeographic changes).
4. The results of investigations in the North Kamchatka Paleogene have been presented in some publications, e.g. Gladenkov Y. North Pacific molluscan assemblages and paleogeography in the early Paleocene // Climate and Biota of Early Paleogene. Austrian Journal of Earth Sci. Vienna. 2012. Vol. 105/1. pp. 68-71; Gladenkov A. First data on the Eocene diatoms from the marine Paleogene stratigraphic key sections of northeast Kamchatka, Russia // ibid. pp. 63-67.
