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. -
Lake and Mire Isolation Data Set for the Estimation of Post-Glacial Land Uplift in Fennoscandia
Lake and mire isolation data set for the estimation of post-glacial land uplift in Fennoscandia Jari Pohjola1, Jari Turunen1, and Tarmo Lipping1 1Tampere University, Pohjoisranta 11 A, Pori, Finland Correspondence to: Jari Pohjola (jari.pohjola@tuni.fi) Abstract. Postglacial land uplift is a complex process related to the continental ice retreat that took place about 10,000 years ago and thus started the viscoelastic response of the Earth’s crust to rebound back to its equilibrium state. To empirically model the land uplift process based on past behavior of shoreline displacement, data points of known spatial location, elevation and dating are needed. Such data can be obtained by studying the isolation of lakes and mires from the sea. Archaeological data 5 on human settlements (i.e., human remains, fireplaces etc.) are also very useful as the settlements were indeed situated on dry land and were often located close to the coast. This information can be used to validate and update the postglacial land uplift model. In this paper, a collection of data underlying empirical land uplift modelling in Fennoscandia is presented. The data set is available at https://doi.org/10.1594/PANGAEA.905352 (Pohjola et al., 2019). 1 Introduction 10 Holocene land uplift has been known to people living along the shores of the northern Baltic Sea for centuries. Land uplift is a consequence of the Weichselian stadial and the massive ice layer that covered the Northern Europe from the British Isles to the proximity of Ural mountains in Russia. Heavy ice load pressed the Earth’s crust down during the Weichselian period and when the ice started to melt at the beginning of the post-Weichselian or the Holocene period, the crust began to rebound to its equilibrium state. -
Lake Pyhäjärvi, SW Finland
Quantifying the Groundwater Component within the Water Balance of a Large Lake in a Glaciated Watershed: Lake Pyhäjärvi, SW Finland by Andrew James Wiebe A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Master of Science in Earth Sciences Waterloo, Ontario, Canada, 2012 ©Andrew James Wiebe 2012 AUTHOR'S DECLARATION I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract Accurate estimates of the amount of groundwater entering a lake on a yearly basis may provide valuable information for assessing contaminant loadings such as nutrient mass fluxes and the subsequent contribution of groundwater to eutrophication. Groundwater exchange with lakes is often a critical component of a lake’s water balance, yet its quantification has often proven problematic. Large component uncertainties preclude accurate estimation of the groundwater flux, upon which the assessment of contaminant loadings may depend. In this study, water balance techniques for lake systems were assessed at Lake Pyhäjärvi (near Säkylä, SW Finland), a relatively large lake in a long established agricultural area. A water balance was conducted over 38 water years to estimate the net groundwater discharge into the lake. This was compared with groundwater flux estimates via Darcy’s Law for the adjacent Honkala Aquifer in the Kuivalahti-Säkylä tributary esker (a potential conduit for groundwater impacted by agricultural practices). Direct runoff estimates were initially made using an average of river flow per unit area ratios from the two rivers that flow into the lake. -

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. -
