Baltijos jūros krantai prieš 10 000 metų

LTLeidinyje pateikiama moksliniais tyrimais paremta povandeninio kraštovaizdžio ties buvusia Joldijos jūros kranto linija rekonstrukcija. Tyrinėtoje vietoje buvo nustatyta Joldijos jūros pakrantės augmenija (miškų sudėtis, jų amžius, žolės danga) ir gamtinės sąlygos, kurios leidžia spėti apie paleolito-mezolito laikotarpio žmogaus gyvenseną prie Joldijos jūros krantų. Tai naujausi Klaipėdos universiteto Baltijos regiono istorijos ir archeologijos instituto (KU BRIAI) Povandeninių tyrimų centro (PTC) duomenys. Pastarieji tyrimai remiasi Baltijos jūros dugno distanciniais ir tiesioginiais žvalgymais bei laboratoriniais tyrimais: iš po vandeniu aptiktų objektų paimtų bandinių palinologinėmis ir dendrochronologinėmis analizėmis, radiokarboniniu datavimu.

ENThe publication provides underwater landscape research results: establishment of Yoldia Sea coastline location near Juodkrantė, Yoldia seashore underwater landscape reconstruction (coastal vegetation: relic forest composition, their age, herbal composition), the evolution of Palaeolithic-Mesolithic human development near Yoldia Sea coast. 2011 - 2012 the Klaipėda University Institute of Baltic Sea Region History and Archaeology scientists (IBSRHA), worked on the research project “Early Holocene natural and cultural landscapes research at the bottom of the Baltic Sea (Yoldia). This research was funded by a grant (No. MIP-005/2011) from the Research Council of Lithuania. The project was designed to continue and expand on studies in 2010 (which were carried out Klaipėda University IBSRHA resources), which revealed the existence of relict forest remains from the formation of the Baltic Sea in Yoldia-Ancylus period at the seabed in Juodkrantė location. In order to localize the former Yoldia Sea coasts, the environment and their potential settlement development in Lithuanian waters in the area at about 30 km2 near the Juodkrantė following research aims were established.1. To systematize and to summarize geological, geophysical and archaeological material in Lithuanian waters equator of the Baltic Sea and on the its coastline in the Early Holocene period. 2. In the sea bottom area of 16 km2 surveys were made with side-scan sonar and multi-beam (in 2010 were research was conducted in area of 14 km2) for the purpose of interpretation of relict trees locations, to make detailed bathymetric measurements, to identify underwater relict forest’s tree stumps and trunks, to find locations of in situ remnants of humus or peat layers, perform photo and video fixation underwater, taking samples for laboratory analysis. 3. Develop detailed picture of seabed relief, to identify former Yoldia Sea position, simulation of palaeo-geographical environment, landscape and coastal vegetation, based on underwater archaeological and geological surveys 4. To make the tree-ring and pollen analysis as well as Radiocarbon dating from the material gathered during underwater archaeological research in order to indentify Yoldia Sea coasts, their time of settlement and sea-level fluctuation levels.
