“…140 ka. These volcanic event layers provide information on ash dispersal from the prominent volcanic regions in Italy and contribute significantly to the construction of a robust chronology by comparison with other dated records in the region using tephrochronological cross-correlation of geochemical fingerprints Caron et al, 2010;Vogel et al, 2010b;Damaschke et al, 2013). In addition, analysis of Lake Ohrid sediments will generate information on tectonic events.…”

Abstract. The Scientific Collaboration on Past Speciation Conditions in Lake Ohrid (SCOPSCO) project is an international research initiative to study the influence of major geological and environmental events on the biological evolution of lake taxa. SCOPSCO drilling campaigns were carried out in 2011 and 2013. In 2011 we used gravity and piston coring at one of the five proposed drill sites, and in 2013 we undertook deep drilling with the Deep Lake Drilling System (DLDS) of Drilling, Observation and Sampling of the Earth's Continental Crust (DOSECC). In April and May 2013, a total of 2100 m sediments were recovered from four drill sites with water depths ranging from 125 to 260 m. The maximum drill depth was 569 m below the lake floor in the centre of the lake. By retrieving overlapping sediment sequences, 95 % of the sediment succession was recovered. Initial data from borehole logging, core logging and geochemical measurements indicate that the sediment succession covers > 1.2 million years (Ma) in a quasi-continuous sequence. These early findings suggest that the record from Lake Ohrid will substantially improve the knowledge of long-term environmental change and short-term geological events in the northeastern Mediterranean region, which forms the basis for improving understanding of the influence of major geological and environmental events on the biological evolution of endemic species.Published by Copernicus Publications on behalf of the IODP and the ICDP.

“…The ESR dates of the Dreissena shells and shell fragments from the Lake Prespa core provide a mean age for the deposition of the shell horizon and the reconstructed lake level lowstand of 73.6 ± 7.7 ka (Damaschke et al, 2013). Despite relatively large uncertainty, the mean age is supported by tephrostratigraphic markers above the shell horizon and by chronological tie points below and above the shell horizon (Damaschke et al, 2013).…”

“…Published data from Lake Prespa indicate that the sedimentary record is very sensitive to environmental change over the last 92 ka, which is partly due to a relatively small volume (3.6 km 3 ), a large surface area (254 km 2 ), and a mean water depth of only ca. 14 m (Wilke et al, 2010;Damaschke et al, 2013;Wagner et al, 2012;Leng et al, 2013;Panagiotopoulos et al, 2013b). However, none of the published studies have considered that the sedimentary record could indicate the impact of the 74 (75) ka Toba eruption.…”

“…Despite relatively large uncertainty, the mean age is supported by tephrostratigraphic markers above the shell horizon and by chronological tie points below and above the shell horizon (Damaschke et al, 2013). The chronological tie points were obtained by cross correlation of mainly TOC, which is known to be a very sensitive proxy of climatic change in the Lake Prespa sediments , with the NGRIP ice core record (Fig.…”

Distinct lake level lowstand in Lake Prespa (SE Europe) at the time of the 74 (75) ka Toba eruption

Abstract. The 74 (75) ka Toba eruption in Sumatra, Indonesia, is considered to be one of the largest volcanic events during the Quaternary. Tephra from the Toba eruption has been found in many terrestrial and marine sedimentary deposits, and acidity peaks related to the eruption have been used to synchronize ice core records from Greenland and Antarctica. Seismic profiles and sedimentological data from Lake Prespa on the Balkan Peninsula, SE Europe, indicate a lake level lowstand at 73.6 ± 7.7 ka based on ESR dating of shells. Tephrostratigraphy, radiocarbon dating and tuning of the total organic carbon content with the NGRIP isotope record, corroborate that the lake level lowstand was a short-term event superimposed on the general cooling trend at the end of MIS 5, most likely at the onset of the Greenland Stadial GS-20. Acknowledging that tectonic events or karst processes could have triggered this lake level lowstand, the chronological correspondence between the lowstand and the Toba eruption is intriguing. Therefore a Toba-driven short-term shift to aridity in the Balkan region, leading to lake level changes and triggering spatial expansion events in one of the lake's most abundant benthic species, the carino mussel Dreissena presbensis, cannot be excluded.

In this paper, we provide chronological constraints to reconstruct the Late Middle Pleistocene to Holocene geomorphological, stratigraphical and tectonic evolution of the inner Sarno plain, along the Tyrrhenian flank of Southern Italy. These constraints derive from tephrostratigraphical analysis and 40Ar/39Ar dating of volcanic deposits, chronologically constrained between ca. 40 ka and 184 ka, recovered from a borehole located in the pediment of the Sarno Mts. The lack of marine to transitional deposits in the borehole testifies that the entire area has been above sea level during this period. Conversely, analysis of previously drilled borehole data indicates the presence of an at least 200 m thick sequence of marine and transitional deposits beneath the Sarno Plain. The top of the marine to transitional deposits in the Sarno basin has been correlated with those in the San Valentino Torio High to the SW, dated to the MIS 5. Consequently, it may be envisaged that the upper portion of the marine deposits in the Sarno Plain also correlates with the MIS 5. This allows to estimate a mean subsidence rate in the last 125 ka, which is 0.32 mm/a. On the other hand, the uninterrupted 200 m‐thick marine succession means that subsidence in the Sarno basin was ≥0.7 mm/a during the preceding interval between ~285 ka and the last interglacial (LIG; MIS 9‐MIS 5). The subsidence was likely driven by the activity of the Sarno Fault, whose slip rate in the last 40 ka was significantly lower than the subsidence rate since the LIG and the MIS 9‐LIG interval. This implies that the fault slip rate has decreased during the last 285 ka. This paper provides a valuable contribution to the study of the complex interplay between glacio‐eustatic oscillations and tectonics to assess reliable paleo‐sea level indicators.
