    Description: Lake Ohrid (Macedonia, Albania) is thought to be more than 1.2 million years old and host more than 300 endemic species. As a target of the International Continental scientific Drilling Program (ICDP), a successful deep drilling campaign was carried out within the scope of the Scientific Collaboration on Past Speciation Conditions in Lake Ohrid (SCOPSCO) project in 2013. Here, we present lithological, sedimentological, and (bio-)geochemical data from the upper 247.8m composite depth of the overall 569m long DEEP site sediment succession from the central part of the lake. According to an age model, which is based on 11 tephra layers (first-order tie points) and on tuning of bio-geochemical proxy data to orbital parameters (second-order tie points), the analyzed sediment sequence covers the last 637 kyr. The DEEP site sediment succession consists of hemipelagic sediments, which are interspersed by several tephra layers and infrequent, thin (〈 5 cm) mass wasting deposits. The hemipelagic sediments can be classified into three different lithotypes. Lithotype 1 and 2 deposits comprise calcareous and slightly calcareous silty clay and are predominantly attributed to interglacial periods with high primary productivity in the lake during summer and reduced mixing during winter. The data suggest that high ion and nutrient concentrations in the lake water promoted calcite precipitation and diatom growth in the epilimnion during MIS15, 13, and 5. Following a strong primary productivity, highest interglacial temperatures can be reported for marine isotope stages (MIS) 11 and 5, whereas MIS15, 13, 9, and 7 were comparably cooler. Lithotype 3 deposits consist of clastic, silty clayey material and predominantly represent glacial periods with low primary productivity during summer and longer and intensified mixing during winter. The data imply that the most severe glacial conditions at Lake Ohrid persisted during MIS16, 12, 10, and 6, whereas somewhat warmer temperatures can be inferred for MIS14, 8, 4, and 2. Interglacial-like conditions occurred during parts of MIS14 and 8.

    Description: This dataset presents the chronological framework, (bio-)geochemical, mineralogic stable isotope, pollen, and tephrochronologic data of the upper 448 m of the DEEP site (5045-1) sediment sequence recovered from the central part of Lake Ohrid (Macedonia, Albania) under the umbrella of the International Continental Scientific Drilling Program (ICDP) and the project Scientific Collaboration on Past Speciation Conditions in Lake Ohrid (SCOPSCO). The investigated interval comprises fine-grained muds with intercalated tephra layers and mass movement deposits of mostly less than 5 cm thickness. Two tephra layers of thicknesses more than 5 cm were excluded prior to age-depth modelling, which is based on tephrostratigraphy, tephrochronology, magnetostratigraphy, and tuning of biogeochemical proxy data versus local orbital parameters. (Bio-)geochemical analyses comprise X-Ray fluorescence scanning at 2.5 mm resolution (Potassium and Calcium intensities), and total inorganic carbon (TOC) and total organic carbon (TOC) determinations at 16 cm resolution. The relative abundance of quartz minerals (Quartz peak area, 16 cm resolution) was detected by means of Fourier Transform Infrared Spectrometry (FTIRS). Oxygen and carbon stable isotope were analysed on (interglacial) sediments where endogenic calcite crystals were found to be abundant. Pollen data presented herein at 64 cm resolution comprise a sub-dataset of the total pollen counts and presents relative percentages of arboreal taxa minus pine (AP-pine), and of deciduous oaks, respectively. Tephrochronologic data comprises geochemical fingerprint analyses of individual glass shards found in the sediments of Lake Ohrid, and a new Ar/Ar age for tephra V5 from the Montalbano Jonico section. Climate time series data are derived from a transient 784 ka simulation using the earth system model LOVECLIM as well as NOAA reanalysis precipitation data of the Lake Ohrid region for the tim period 1979-2017.

    Description: Here we present a multi-proxy record from palaeolake Fucino (Abruzzo, Central Italy), acquired during the F1-F3 drilling campaign. This is the first continuous and high-resolution palaeoenvironmental record in the central Mediterranean region continuously spanning over the last two glacial-interglacial cycles and providing an independent chronology. The record consists of a core composite resulting from two parallel and adjacent core series (F1 and F3). Cores were analysed via high resolution XRF scanning and through geochemical, mineralogical and grain-size analyses on discrete samples. Selected XRF elemental counts (Ca, Ti and Zr), Total Nitrogen (TN), Total Organic and Inorganic Carbon (TOC, TIC), X-ray powder diffraction and grain-size data are used to develop proxies for local environmental processes strictly dependent on the hydro-climatic regime of the Central Mediterranean region. The chronology of the record is based on 17 radioisotopically dated tephra layers interbedded within the sedimentary succession. 14C and 40Ar/39Ar age points are interpolated with the bayesian age modelling package Bacon allowing a robust assessment of age uncertainties.

    Environmental variability between the penultimate deglaciation and the mid Eemian: Insights from Tana che Urla (central Italy) speleothem trace element record (2018)
    Details
    Publication Date: 2018-03-30
    Description: A trace element record (Mg, Sr, Ba, Al, Si, P, Y, Zn) covering the ca. 133 ka to ca. 124 ka time interval was acquired from a flowstone core from Tana che Urla Cave (central Italy). It was compared with stable isotope data to investigate the environmental evolution in response to regional and extra-regional climate changes in the period corresponding to the latter part of the Penultimate Deglaciation and the first part of the Last Interglacial (Eemian). Trace element geochemical changes on centennial and millennial time scales responded to changes in hydrological input, variations in the supply and transport of catchment erosion products to the cave, including those linked to intense rainfall events, and to the state of the overlying soil and vegetation. Abrupt increases in precipitation and the progressive development of soil and vegetation occurred at ca. 132 ka, in response to the development of the global deglacial phase. The major changes in trace element composition are coherent with the previous hydrological interpretation of speleothem oxygen stable isotope composition (δ18O) as predominantly a rainfall-amount proxy. However, reduced growth rate persisted until ca. 130 ka, suggesting still depressed temperatures. An abrupt event of climatic deterioration, with marked decrease in precipitation and soil degradation, is apparent between ca. 131 and 130 ka. Cool-wet conditions between ca. 132 and 131 ka and the subsequent dry period may represent the local hydrological response to an interval of North Atlantic cooling and ice-rafted-debris (IRD) deposition known as Heinrich event 11 (H11). After 129.6 ka there was a rapid recovery according to all of the studied speleothem properties, indicating the onset of full interglacial conditions. A minor amplitude event of reduced precipitation is recorded within the LIG at ca. 127 ka. The record highlights the growing regional evidence for a complex penultimate deglacial climate involving major reorganization of oceanic and atmospheric patterns.

    Constraining the end of the Last Interglacial (MIS 5e) relative sea-level highstand in central Mediterranean: New data from Grotta delle Capre, central Italy (2024)
    Elsevier
    Details
    Publication Date: 2024-01-29
    Description: The current rapid change of the Earth’s climate has resulted in an increasing interest for the past warm periods as potential long-term scenarios of the effects of the present global warming. The last such a period occurred 129–116 ka, known as the Last Interglacial (LIG), when the continental ice volume was significantly smaller than present, leading to a global sea-level (GSL) higher than present one. Detailed morpho-stratigraphic data, supported by a robust U/Th chronology, from Grotta delle Capre, central Italy, provided new chronological insights on the relative sea-level (RSL) dynamic during the LIG in the Mediterranean region. Our results indicate that, on Tyrrhenian Sea coasts of the central Italy, after having stationed at ~9 m a.s.l., the LIG RSL fell at an elevation 〈3 m a.s.l. as early as before 123 ka, and then no longer rose above this elevation either during the later stages of the LIG or afterwards. The results match previous studies based on U/Th dating of terrestrial limiting points from Grotta Infreschi, ~200 km SE from Grotta delle Capre along the same Tyrrhenian Sea coasts, and are in agreement with the Red Sea RLS and GSL records and the probabilistic LIG sea level assessments based on globally distributed records. On the other hand, our reconstruction is not supported by implications of U/Th dating of corals and phreatic overgrowth on speleothems from the Balearic Island of Mallorca. Such an inconsistency in the overall knowledge around the LIG RSL reconstruction results in a high uncertainty in modelling the ice and sea-level dynamic during this warm period, which needs to be reduced through more and more highresolution, stratigraphic and chronological investigations of the morphological and sedimentary sea-level records.
