The Problem of . the Cochrane in Late Pleistocene * Chronology
The Problem of . the Cochrane in Late Pleistocene * Chronology ¥ GEOLOGICAL SURVEY BULLETIN 1021-J A CONTRIBUTION TO GENERAL GEOLOGY 4 - THE PROBLEM OF THE COCHRANE IN LATE PLEISTOCENE CHRONOLOGY By THOR N. V. KAKLSTROM .ABSTRACT The precise position of the Cochrane readvances in the Pleistocene continental chronology has long been uncertain. Four radiocarbon samples bearing on the age of the Cochrane events were recently dated by the U. S. Geological Survey. Two samples (W-241 and W-242), collected from organic beds underlying sur face drift in the Cochrane area, Ontario, are more than 38,000 years old. Two samples (W-136 and W-176), collected from forest beds near the base and middle of a 4- to 6-foot-thick peat section overlying glacial lake sediments deposited after ice had retreated north of Cochrane, have ages, consistent with stratigraphic position, of 6,380±350 and 5,800±300 years. These results indicate that the Cochrane area may have been under a continuous ice cover from before 36,000 until some time before 4500 B. C.; this conforms with the radiocarbon dates of the intervening substage events of the Wisconsin glaciation. The radiocarbon results indicate that the Cochrane preceded rather than followed the Altither- mal climatic period and suggest that the Cochrane be considered a Wisconsin event of substage rank. Presented geoclimatic data seemingly give a consistent record of a glaciation and eustatic sea level low between 7000 and 4500 B. C., which appears to corre late with the Cochrane as a post-Mankato and pre-Altithermal event. A direct relation between glacial and atmospheric humidity changes is revealed by com paring the glacioeustatic history of late Pleistocene and Recent time with inde pendently dated drier intervals recorded from Western United States, Canada, and Europe. -

Ridge 617-627-3494 or 617-627-2890 Dept. of Geology [email protected] Tufts University Medford, MA 02155 1 1. Project Summary Intellectual merit. Rapid climate change events during deglaciation are closely linked to ice sheet, ocean, and atmosphere interactions. Understanding these interactions requires high resolution comparisons of climate and continental ice dynamics. Although general patterns of Laurentide Ice Sheet (LIS) variation have been discerned, they are not continuously resolved at a sub-century scale. This lack of continuous, high-resolution terrestrial glacial chronologies with accurate radiometric controls continues to be a limiting factor in understanding deglacial climate. Such records, especially from the southeastern sector of the LIS, can provide critical comparisons to N. Atlantic climate records (marine and ice core) and a rigorous test of hypotheses linking glacial activity to climate change. Consolidation of the New England Varve Chronology (NEVC), and development of its records of glacier dynamics and terrestrial change, is a rare opportunity to formulate a complete, annual-scale terrestrial chronology from 18-11.5 kyr BP. Glacial varve deposition, which is linked to glacial meltwater discharge, can be used to monitor ice sheet ablation and has a direct tie to glacier mass balance and climate. -

Late Weichselian and Holocene Shore Displacement History of the Baltic Sea in Finland
Late Weichselian and Holocene shore displacement history of the Baltic Sea in Finland MATTI TIKKANEN AND JUHA OKSANEN Tikkanen, Matti & Juha Oksanen (2002). Late Weichselian and Holocene shore displacement history of the Baltic Sea in Finland. Fennia 180: 1–2, pp. 9–20. Helsinki. ISSN 0015-0010. About 62 percent of Finland’s current surface area has been covered by the waters of the Baltic basin at some stage. The highest shorelines are located at a present altitude of about 220 metres above sea level in the north and 100 metres above sea level in the south-east. The nature of the Baltic Sea has alter- nated in the course of its four main postglacial stages between a freshwater lake and a brackish water basin connected to the outside ocean by narrow straits. This article provides a general overview of the principal stages in the history of the Baltic Sea and examines the regional influence of the associated shore displacement phenomena within Finland. The maps depicting the vari- ous stages have been generated digitally by GIS techniques. Following deglaciation, the freshwater Baltic Ice Lake (12,600–10,300 BP) built up against the ice margin to reach a level 25 metres above that of the ocean, with an outflow through the straits of Öresund. At this stage the only substantial land areas in Finland were in the east and south-east. Around 10,300 BP this ice lake discharged through a number of channels that opened up in central Sweden until it reached the ocean level, marking the beginning of the mildly saline Yoldia Sea stage (10,300–9500 BP). -

These investigations have revealed sedimentary evidence of the Yoldia Sea regression, the Ancient Lake Vättern transgression, and the following stepwise river formation process. Around 9000 cal BC, two small kettlehole basins at Strandvägen and Kanaljorden became isolated from the Baltic basin. As the ice sheet retreated further north, the isostatic uplift isolated the Vättern basin from the Baltic basin. Due to the uneven isostatic uplift, the basin tilted toward the south, and the Ancient Lake Vättern transgression started in Motala. The threshold in Motala at 92.5 m a.s.l. was reached around 7200 cal BC, and River Motala Ström was formed. -

Reid and Marina I. Orlova1 Abstract: Between 1985 and 2000, ~70% of new species that invaded the North American Great Lakes were endemic to the Ponto-Caspian (Caspian, Azov, and Black seas) basins of eastern Europe. Sixteen Ponto-Caspian species were also established in the Baltic Sea as of 2000. Many Ponto-Caspian endemic species are characterized by wide environmental tolerances and high phenotypic variability. Ponto-Caspian fauna evolved over millions of years in a series of large lakes and seas with widely varying salinities and water levels and alternating periods of isolation and open connections between the Caspian Sea and Black Sea depressions and between these basins and the Mediterranean Basin and the World Ocean. These conditions probably resulted in selection of Ponto-Caspian endemic species for the broad environmental tolerances and euryhalinity many exhibit. Both the Baltic Sea and the Great Lakes are geologi- cally young and present much lower levels of endemism. The high tolerance of Ponto-Caspian fauna to varying environmental conditions, their ability to survive exposure to a range of salinities, and the similarity in environmental conditions available in the Baltic Sea and Great Lakes probably contribute to the invasion success of these species. Human activities have dramatically increased the opportunities for transport and introduction and have played a cata- lytic role. Résumé : Entre 1985 et 2000, environ 70 % des espèces qui ont envahi pour la première fois les Grands-Lacs d’Amérique du Nord étaient endémiques aux bassins versants de la région pontocaspienne de l’Europe de l’Est, soit ceux de la mer Caspienne, de la mer d’Azov et de la mer Noire. -
