Jacqueline LaPerriere talks about the expedition to St. Lawrence Island with Dr. Nako who is from the Geophysics Department at the University of Hokkaido at Sapporo, being the local scientist for the project, taking cores of the ancient lake sediments on St. Lawrence Island so they can look at the climate of the ancient world, Dr. Nako looking for what the climate was like under the arctic air mass during particular times since and before the last glaciation, Dr. Nako's expertise on ancient lake hydrology, granulometric analysis, looking at the size of the grains in the core for information about precipitation and flow coming into the lake, other scientists attached to his team, Ferro-magnetic orientation, carbon dating of the core, a pollen scientist, Dr. Maida, hypothesis about climatic change, what caused it to occur and what accompanied those changes over time, looking for evidences of these changes and testing their hypothesis, how Dr. Nako came to Alaska and worked at Harding Lake in 1979, the team's activities on St. Lawrence Island, water chemistry studies, coring several lakes, taking detailed hydrologic measurements, coring at Harding Lake, the method of coring they used on St. Lawrence Island, the theory that St. Lawrence Island was part of the Bering Land Bridge during ancient times when there was a land connection between Siberia and Alaska, determining if there were trees on St. Lawrence Island at one time through pollen studies, and her role as coordinator for the expedition team.
