Article
We investigated the calcareous nannofossil biostratigraphy and magnetostratigraphy of middle Eocene – lower Oligocene sediments from ODP Hole 709 C, equatorial Indian Ocean. The new bio-magnetostratigraphic analyses have resulted in an accurate biochronology of the interval spanning Chrons C20r (middle Eocene) to C12r, in which 29 bioevents were in...
Article
A marine sediment core from the western Mediterranean provides a new high-resolution 4500 year record of palaeomagnetic secular variation and relative palaeointensity. In 2013, the 7.1 m C5 core was recovered from the Tyrrhenian Sea as part of the NextData climate data project. The coring site, 15 km offshore from the Volturno river mouth, is well...
Article
A new high-resolution pollen record, spanning the last five millennia, is presented from the Gulf of Gaeta (Tyrrhenian Sea, central Italy), with the aim of verifying if any vegetation change occurred in the central Mediterranean region in relation to specific well-known global and/or regional climate events, including the 4.2 ka event, the Medieval...

A new annually resolved sedimentary record of Southern Hemisphere mid-latitude hydroclimate was recovered from Lake Ohau, South Island, New Zealand, in March 2016. The Lake Ohau Climate History (LOCH) project acquired cores from two sites (LOCH-1 and -2) that preserve sequences of laminated mud that accumulated since the lake formed ∼ 17000 years a...

Antarctic climate changes have been reconstructed from ice and sediment cores and numerical models (which also predict future changes). Major ice sheets first appeared 34 million years ago (Ma) and fluctuated throughout the Oligocene, with an overall cooling trend. Ice volume more than doubled at the Oligocene-Miocene boundary. Fluctuating Miocene...

After the formalization of the base of the Miocene in the Lemme-Carrosio section (Italy) at the base of Subchron C6Cn.2n, the calcareous plankton biostratigraphy was refined in several open ocean Deep Sea Drilling Project/Ocean Drilling Program sites. However, high-resolution quantitative biostratigraphic studies, integrating planktonic foraminifer...
Poster
In this study, we investigate the calcareous nannofossil biostratigraphy and magnetostratigraphy of middle Eocene – lower Oligocene sediments from ODP 709C. Our goal is to test the reliability in the Indian Ocean of the biohorizons recently identified at Site 711 (Fioroni et al., 2015), by means of quantitative analyses on calcareous nannofossils....
Conference Paper
Full-text available
A new high resolution pollen, planktonic foraminiferal and oxygen isotopes record from a shallow water marine sedimentary core from the central Tyrrhenian Sea (Gulf of Gaeta) provides information on vegetation and climate changes occurred in the central Mediterranean region during the last 5000 cal. years BP (Margaritelli et al., 2016). Nine tim...

Benthic foraminifera are single-celled eukaryotes that make a protective organic, agglutinated or calcareous test. Some agglutinated, single-chambered taxa, including Psammophaga Arnold, 1982, retain mineral particles in their cytoplasm, but the selective mechanism of accumulation is not clear. Here, we report the ability of a foraminiferal species...
Article
Full-text available
We report new data regarding the environmental history of the Taranto Area since MIS 11, which possibly led to the peculiar sediment preservation characterizing the Fronte Section. This section is a very promising candidate for the Upper Pleistocene GSSP. Some preliminary results achieved after the multiple core drilling at the Fronte locality (Tar...

New magnetobiostratigraphic data for the Late Oligocene through early Miocene at Deep Sea Drilling Project (DSDP) Hole 516F provide a significantly revised age model, which permits reevaluation of developments that led to the Mi-1 glacial event at the Oligocene-Miocene boundary. Our new high-resolution paleomagnetic study, which is supported by qua...
Article
Full-text available
The Roveto Valley is a narrow, elongated, NW-trending depression filled with continental Plio-Quaternary deposits that outcrop at different topographic elevations. A morpho-lithostratigraphic succession of the continental deposits has been defined in order to reconstruct the geological Quaternary evolution of the area. These deposits do not contain...

We present new data collected at the Fronte composite section near Taranto, where the Upper Pleistocene marine sedimentary succession is continuously exposed. Above a fossiliferous calcarenite yielding the “Senegalese” fauna, and abundant Cladocora, the 230Th/U age of which is consistent with Marine Isotope Stage (MIS) 5, a 6.25 m thick pelitic uni...

PuffinPlot is a user-friendly desktop application for analysis of paleomagnetic data, offering a unique combination of features. It runs on several operating systems, including Windows, Mac OS X, and Linux; supports both discrete and long core data; and facilitates analysis of very weakly magnetic samples. As well as interactive graphical operation...
Article
The palaeoenvironmental significance of glaucony has long been appreciated, but accurately dating the events recorded by glauconitic horizons often requires an understanding of its palaeomagnetic behaviour. We present the results of the first investigation into the relationship between glaucony and remanence acquisition. Pure glauconitic minerals a...
Thesis
Full-text available
When did the first ice form on Antarctica? Large, stable ice sheets started to appear in the Oligocene, but there may have been earlier, transient Palaeocene glaciations which left only brief traces in the sedimentary record. Correlation of such traces across the New Zealand region requires the accuracy provided by magnetostratigraphic dating. Howe...
Thesis
Full-text available
Disambiguating an utterance occurring in a dialogue context is a complex task, which requires input from many different sources of information -- some syntactic, some semantic, and some pragmatic. The central question addressed by this thesis is how to integrate data sources for utterance disambiguation within a bilingual human-computer dialogue s...
Article
Full-text available
We discuss the data sources available for ut-terance disambiguation in a bilingual dialogue system, distinguishing global, contextual, and user-specific domains, and syntactic and seman-tic levels. We propose a framework for combin-ing the available information, and techniques for increasing a stochastic grammar's sensitivity to local context and a...

Project
Mountains are sentinels of climate and environmental change and many marine regions provide information on past climate variations. The Project of Interest NextData will favour the implementation of measurement networks in remote mountain and marine areas and will develop efficient web portals to access meteoclimatic and atmospheric composition data, past climate information from ice and sediment cores, biodiversity and ecosystem data, measurements of the hydrological cycle, marine reanalyses and climate projections at global and regional scale. New data on the present and past climatic variability and future climate projections in the Alps, the Himalaya-Karakoram, the Mediterranean region and other areas of interest will be obtained and made available. The pilot studies conducted during the project will allow for obtaining new estimates on the availability of water resources and on the effects of atmospheric aerosols on high-altitude environments, as well as new assessments of the impact of climate change on ecosystems, health and societies in mountain regions. The system of archives and the scientific results produced by the NextData project will provide a unique data base for research, for environmental management and for the estimate of climate change impacts, allowing for the development of knowledge-based environmental and climate adaptation policies. The NextData Project has defined three Grand Challenges: (1) the construction of a system of archives and portals for distributing climate and environmental data on current conditions and ongoing changes in mountain regions; (2) the reconstruction of climate and its variability in Italy in the last two Millennia, with special focus on the last 100 years; and (3) the development of an ensemble of high-resolution downscaled temperature and precipitation fields from future climate scenarios over Italy for the next few decades.
