A Bayesian change point analysis re-examines the 4.2 ka BP event in southeast Europe and southwest Asia
Ön, Zeki Bora (PERGAMON-ELSEVIER SCIENCE LTD, 2023)The 4.2 ka BP event is a hypothesized global drought and cooling event and is claimed to be supported by proxy records from a wide range of geographical locations. However, recent studies have presented contradictory data ... -
A Bayesian test for the 4.2 ka BP abrupt climatic change event in southeast Europe and southwest Asia using structural time series analysis of paleoclimate data
Ön, Zeki Bora; Greaves, Alan; Akçer Ön, Sena; Özeren, M. Sinan (Springer, 2021)It has been proposed that there was an abrupt climatic change event around 4.2 ka BP that affected societies and even has been linked to the collapse of empires. Subsequent studies have reached conclusions that both support ... -
High-resolution temperature and precipitation variability of southwest Anatolia since 1730 CE from Lake Golcuk sedimentary records
Danladı, Iliya Bauchi; Akçer Ön, Sena; Ön, Zeki Bora; Schmidt, Sabine (TÜBİTAK, 2021)We report high-resolution multiproxy analyses [lithology, mu XRF and magnetic susceptibility (MS)] of two short gravity sediment cores from the crater Lake Golcuk, southwest Turkey. Our results provide a detailed hydroclimatic ... -
Late Pleistocene to Holocene paleoenvironmental evolution of Lake Hazar, Eastern Anatolia, Turkey
Eriş, Kürşad Kadir; Ön, Sena Akçer; Çağatay, M. Namık; Ülgen, Umut Barış; Ön, Zeki Bora; Gürocak, Zülfü; Okan, Özlem Öztekin (Pergamon-Elsevier Science Ltd, 2018)High-resolution seismic reflection profiles and core analyses in Lake Hazar provide a detailed record of the lake level fluctuations and the robust chronology of paleoclimatic events of the Eastern Anatolia during the late ... -
A novel Bayesian multilevel regression approach to the reconstruction of an eastern Mediterranean temperature record for the last 10,000 years
Ön, Zeki Bora; Macdonald, Neil; Akcer-On, Sena; Greaves, Alan M. (SAGE PUBLICATIONS LTD, 2023)Climate reconstructions derived from proxy records for individual sites often fail to incorporate existing regional information, which may help to determine uncertainties and express variability within specific reconstructions ... -
Temperature and precipitation variability in eastern Anatolia: Results from independent component analysis of Lake Van sediment data spanning the last 250 kyr BP
Ön, Zeki Bora; Özeren, M Sinan (Pergamon-Elsevier Science Ltd, 2019)In this study, we present the results of independent component analysis (ICA) of previously published Lake Van data covering the last 250 kyr BP, to shed light on the precipitation and temperature regime in eastern Anatolia. ...
