HOLOCENE ENVIRONMENTAL AND CLiMATIC CHANGE RECORD IN THE MOLLUSCAN FAUNA FROM THE COASTAL AREA OF BUENOS AIRES PROVINCE (ARGENTINA) Marina L. AGUIRRE Departamento Paleozoologfa Invertebrados, Museo de Ciencias Naturales, D Paseo dei Bosque S/N , 1900 La Plata, Argentina. Palaeoenviranmental changes along the coastal area of north-eastern Argentina (SW Atlantic), originated by different sea-Ievel stands since the late Pleistocene, are revealed by the palaeoecology of the bivalves revised and by the whole qualitative and quantitative molluscan composition from marginal marine deposits. An attempt is made to add new evidence for the reconstruction of the recent c1imatic history along the bonaerensian littoral in SE South America, in comparison with other areas of the Southern Hemisphere. The available evidence from the late Quaternary molluscan assemblages along the NE bonaerensian coastal area allows to recognize: 1) a higher sea-Ievel stand (mostly littoral beach ridges at + 2.5-5m a.m.s.L) corresponding to the Holocene interglacial (ca. 8,000-2,000 14C yrs. B. P.; minimum 0.048 to 0.121 D/L ages on Mactra isabelleana) 2) the maximum of the Holocene transgression at least ca. 7,600 B.P. and the peak of the c1imatic optimum ("Hypsithermal") between ca. 7,600 and 5,000 B. P.(53% warm water taxa) 3) a period from around 5,000 to ca.

  • 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).

  • The Late Quaternary Development of the Baltic Sea
    The late Quaternary development of the Baltic Sea Svante Björck, GeoBiosphere Science Centre, Department of Geology, Quaternary Sciences, Lund University, Sölveg. 12, SE-223 62 Lund, Sweden INTRODUCTION Since the last deglaciation of the Baltic basin, which began 15 000-17 000 cal yr BP (calibrated years Before Present) and ended 11 000-10 000 cal yr BP, the Baltic has undergone many very different phases. The nature of these phases were determined by a set of forcing factors: a gradually melting Scandinavian Ice Sheet ending up into an interglacial environment, the highly differential glacio-isostatic uplift within the basin (from 9 mm/yr to -1mm/yr; Ekman 1996), changing geographic position of the controlling sills (Fig. 1), varying depths and widths of the thresholds between the sea and the Baltic basin, and climate change. These factors have caused large variations in salinity and water exchange with the outer ocean, rapid to gradual paleographic alterations with considerable changes of the north-south depth profile with time. For example, the area north of southern Finland-Stockholm has never experienced transgressions, or land submergence, while the developmen south of that latitude has been very complex. The different controlling factors are also responsible for highly variable sedimentation rates, both in time and space, and variations of the aquatic productivity as well as faunal and floral changes. The basic ideas in this article follow the lengthy, but less up-dated version of the Baltic Sea history (Björck, 1995), a more complete reference list and, e.g., the calendar year chronology of the different Baltic phases can be found on: http://www.geol.lu.se/personal/seb/Maps%20of%20the%20Baltic.htm.

NEXT PAGE(S) left BLANK Abstract The salinity influences which ecosystems will dominate in the coastal area and what property radionuclides have. Salinity is also an important boundary condition for the transport models in the geosphere. Knowledge about the past salinity is important background to evaluate the hydrology and geochemistry in the rock and further to assess the radiological consequences of possible releases from a radioactive repository. This report concerns the salinity in the Baltic Sea during the last 8500 calendar years BP. Shore-level data for the inlet areas and proxy (indirect) data for the palaeosalinity and the climate are reviewed. These data is furthered used in a steady-state model for the salt exchange between the Baltic Sea and Kattegat.

COMPILATION OF INFORMATION ON THE CLIMATE AND EVALUATION OF THE HYDROCHEMICAL AND ISOTOPIC COMPOSITION DURING LATE PLEISTOCENE AND HOLOCENE 98-01-07 Cecilia Andersson Intera KB ABSTRACT This report summarises and evaluates some of the existing information on the Late Pleistocene and Holocene climates, i.e. the last 130 000 years. An estimation of the conditions at the Aspo island (southeast Sweden) has also been made during this time span. The knowledge about Late Pleistocene (Eemian Interglacial and Weichselian glacial) is not yet fully understood. There are still a lot of assumptions concerning this period and more information is needed to be able to establish the climatic conditions. This is not the case for the Weichselian deglaciation and the present interglacial, Holocene, for which the environmental conditions are quite certain.

Over the past 25 years since the ratification of the last official Holocene Stratigraphic Chart in Estonia, the stratigraphic framework of global Quaternary geology has significantly progressed. The Pleistocene/Holocene boundary is defined in the NGRIP2 ice core from Greenland, with an age of 11 700 calendar yr b2k (before AD 2000). The International Subcommission on Quaternary Stratigraphy developed a formal tripartite stratigraphical subdivision of the Holocene into the Greenlandian, Northgrippian and Meghalayan stages/ages, each supported by a Global Boundary Stratotype Section and Point (GSSP). All three GSSPs are defined on the basis of geochemical markers reflecting abrupt global climatic events dated with high accuracy and serving as a reliable foundation for cross correlation. In the light of this development we present a new formal subdivision for the Holocene in Estonia. The new chart is climatostratigraphic with tripartite subdivision. The chronological boundaries and corresponding names for the stages/ages are aligned with the International Holocene Stratigraphic Chart.

    BALTICA Volume 22 Number 1 June 2009 : 51-62 Ancylus Lake and Litorina Sea transition on the Island of Saaremaa, Estonia: a pilot study Leili Saarse, Jüri Vassiljev, Alar Rosentau Saarse, L., Vassiljev, J., Rosentau, A., 2009. Ancylus Lake and Litorina Sea transition on the Island of Saaremaa, Estonia: a pilot study. Baltica, Vol. 22 (1), 51-62. Vilnius. ISSN 0067-3064. Abstract Biostratigraphical, sedimentological and magnetic susceptibility analyses and radiocarbon datings of six Holocene lagoonal profiles of the Island of Saaremaa, Estonia were performed. The examined lagoons were formed during the Ancylus Lake regression and the Litorina Sea transgression. Spatial displacement of the Ancylus Lake and Litorina Sea shores was reconstructed using a digital terrain model with the grid size 50 m x 50 m and the development of the island in terms of the changing sea level and land uplift was described. Due to differences in the isostatic uplift rate, the Ancylus Lake beach formations are located between 35 and 25 m and those of the Litorina Sea between 20.5 and 15.5 m above the present sea level. Radiocarbon dates from buried organic sediments suggest that the Litorina Sea transgression started about 8300–8200 cal yr BP and lasted up to 7300 cal yr BP. Keywords : Ancylus Lake, Litorina Sea, Saaremaa Island, 14 C dates, Estonia.
