Athinios Port (Basement lithologies-Eruptive Cycles-Caldera collapse events) Basement Lithologies Athinios Port is located at the southern part of the caldera wall (inside the caldera ring) roughly between Fira (capital) and Akrotiri village (excavations). It is built on the basement metamorphic massif, which is part of the prevolcanic island that formed close to the nowadays center of Santorini Island, from late Mesozoic to early Tertiary during the Alpine folding Orogeny. The metamorphic lithologies represented by low-grade phyllites (metapelites and schists) were found along the caldera wall at Athinios port but also at Profitis Ilias and Mesa Vouno mountains. The metamorphic pathway (P-T path) is characteristic of the metamorphic facies of the typical subduction and exhumation processes influenced by (1) an Eocene high pressure blueschist phase followed by (2) an Oligocene-Miocene greenschist to amphibolite facies overprint (Barrovian metamorphic event, a sequence of regional metamorphic mineral reactions that form typical mineral assemblages) which was associated with a granitic intrusion (mostly about 20 - 9 Ma). The latter, which is part of the Cycladic Granitic Province, is the source of various ore minerals and it is observed at this spot.

  • Responding to Water Challenges in Greece Through Desalination: Energy Considerations
    INTERNATIONAL JOURNAL OF WATER RESOURCES DEVELOPMENT, 2016 VOL. 32, NO. 3, 428–441 http://dx.doi.org/10.1080/07900627.2015.1091290 Responding to water challenges in Greece through desalination: energy considerations A. Kartalidisa, E. Tzenb, E. Kampragkoua and D. Assimacopoulosa aSchool of Chemical Engineering, Technical University of Athens, Athens, Greece; bIndependent Engineer, Athens, Greece ABSTRACT ARTICLE HISTORY Desalination technology, and reverse osmosis in particular, is used Received 15 April 2015 by several island authorities in Greece to address water scarcity. Accepted 3 September 2015 However, this is a highly energy-intensive technique, requiring the KEYWORDS consumption of significant quantities of fossil fuels. The case of Syros Greek islands; desalination; Island is presented, to demonstrate the strong water–energy link in reverse osmosis; RES-powered the operation of desalination plants. The article also discusses the desalination; water scarcity; use of renewable energy sources as a means for reducing the energy greek islands; water-energy intensity of desalination. nexus Introduction Economic development and social well-being depend on two vital resources, energy and water, the links between which are both complex and significant: energy production requires large quantities of water, and supplying water requires significant amounts of energy. The analysis of the “water–energy nexus” demands an integrated view of the production and consumption chains of each resource (Marsh, 2008, presents a depiction of the water–energy nexus complexity), focusing on the core operational components, i.e. infrastructure and technologies (Scott et al., 2011). Particularly for the water supply chain, there is a pressing need to map energy demand along the stages, as the energy intensity of each stage depends on the input water quan- tity and quality.

  • Exile from Olynthus
    Exile From Olynthus Women in Archeology.com Mentoring and Networking Greece, 1927-1928 Raymond Dessy Virginia Tech Wilhelmina van Ingen "Willy" Ethel Bell van Ingen Based upon letters to "my little Mother" from Willy, and her diary entries Prof. David (Davy) Robinson PREFACE Some books are written. Others create themselves. This book grew from a feminine strand of mitochondrial DNA that was stumbled upon in a Classical History course taught by a charismatic Professor, Glen Bugh of Virginia Tech. Dr. Bugh, an Hellenic epigrapher, often lectures aboard the Smithsonian’s sailing ship in the Mediterranean, educating and entertaining its passengers with the world that was around them 2500 years ago. During one lecture at Virginia Tech he mentioned briefly the papers of Wilhelmina van Ingen, a young girl, 22 years of age, who had attended the 1927-1928 American School of Classical Studies at Athens (ASCSA). She had participated in the first years dig at Olynthus in the Spring of 1928, working with Prof. David Robinson. Those papers were found in 15 boxes, totaling ~ 30 cubic feet of space in the Storage area for the Special Collections Division of Newman Library at Virginia Tech. Her husband Herschel Elarth donated the boxes to the University after Dr. van Ingen’s death in 1969. Only half of the collection was then inventoried, but the Control Folder of that material was intriguing. There were personal five-year diaries covering the period from 1927-1968, some personal letters she wrote to her Mother, shoeboxes full of postcards from travels she and her husband made around the world during their marriage, and a hodge-podge of personal papers and mementoes.

  • Reconstruction of the Paleo-Coastline of Santorini Island (Greece), After the 1613 BC Volcanic Eruption: a GIS-Based Quantitative Methodology
    Reconstruction of the paleo-coastline of Santorini island (Greece), after the 1613 BC volcanic eruption: A GIS-based quantitative methodology Dimitrios Oikonomidis∗, Konstantinos Albanakis, Spyridon Pavlides and Michael Fytikas Aristotle University of Thessaloniki, School of Geology, 54124, Thessaloniki, Greece. ∗Corresponding author. e-mail: [email protected] A catastrophic volcanic explosion took place in Thera/Santorini island around 1613 BC, known as the ‘Minoan’ eruption. Many papers have dealt with the shape of the shoreline of the island before the eruption, but none with the shape of the shoreline exactly after it, assuming that it would be the same with the contemporary one. However, this is not correct due to the wave erosion. In this paper, a new DEM was constructed, covering both land and submarine morphology, then topographic sections were drawn around the island. Using these sections, the ‘missing parts’ (sea-wave erosion) were calcu- lated, the shoreline was reconstructed as it was one day after the eruption and finally the erosion rate was calculated. 1.

  • Best Practices of Geoinformatic Technologies for the Mapping of Archaeolandscapes Encourage Their Widespread Adoption by the Archaeological Community
    Sarris (ed) Best Practices of Landscape archaeology is being transformed by the recent development of novel geoinformatic techniques that facilitate entirely new ways to study the archaeological record. Despite this stimulating potential, these techniques are developing so quickly that many practitioners are not fully aware of their capabilities GeoInformatic or the most suitable ways to apply them. This volume presents state of the art research in the fields of geophysics, geochemistry, aerial imaging, dating, digital archaeology, GIS and marine archaeology to provide a comprehensive overview of the specialised techniques which can contribute to landscape scale Technologies for archaeological investigations.
