Sedimentary, geochemical and stable isotope analyses of a sediment core (core AY) recovered from Lake Aygır (NE Anatolia) provide evidence the climatic shifts during last ~500 yrs. Sediments in Aygırare composed silty clay with modeled ~0.16 cm/yr sedimentation rate. Multi-proxy downcore distribution detritally-deposited proxy elements, total calcium carbonate, organic carbon isotopes reveal re...

In the present paper the authors compared skeletal populations (2421 individuals) excavated from four cemeteries, namely Hajdúdorog-Gyúlás (10th century AD), Hajdidorog-Temetöhegy (11th century AD), Hajdúdorog-Katidülö (12th-13th century AD) and Hajdúdorog-Szálldáföld (12th-13th century AD) from a micro-region of Northern Hajdúság (located in the northern part of the Great Hungarian Plain in Hu...

Many sunspot number series exist suggesting different levels of solar activity during the past centuries. Their reliability can be assessed only by comparing them with alternative indirect proxies. We test different sunspot number series against the updated record of cosmogenic radionuclide 44Ti measured in meteorites. Two bounding scenarios of solar activity changes have been considered: the H...
