Agia Bay is located on the southeastern coast of Lemnos Island. The coastal area today characterized by aeolian sandy deposits (dunes). systematic investigation a 15.5-m long sediment core from plain aimed to shed light paleoenvironmental evolution that prehistoric groups occupied. exhaustive study faunal and floral remains including benthic foraminifera, ostracods, mollusks, pollen, dinoflagellate cysts as well plant was further supported sedimentological, micromorphological, elemental...
Abstract Large explosive volcanic eruptions from island arcs pour pyroclastic currents into marine basins, impacting ecosystems and generating tsunamis that threaten coastal communities infrastructures. Risk assessments require robust records of such highly hazardous events, which is challenging as most the products lie buried under sea. Here we report discovery by IODP Expedition 398 a giant rhyolitic pumice deposit emplaced 520 ± 10 ky ago at water depths 200 to 1000 m during...
Abstract Caldera-forming eruptions of silicic volcanic systems are among the most devastating events on Earth. By contrast, post-collapse activity initiating new caldera cycles is generally considered less hazardous. Formed after Santorini’s latest caldera-forming eruption ~1600 bce , Kameni Volcano in southern Aegean Sea enables eruptive evolution a recharging multi-cyclic to be reconstructed. Kameni’s record has been documented by onshore products and historical descriptions mainly...
The consolidation state of sediments provides crucial information about the pore pressure in sediments, as well loading and unloading history sedimentary basins. We performed tests on mudstones calcareous oozes just below thick volcaniclastics Hellenic Arc Volcanic Field, Greece. These were sampled from International Ocean Discovery Program (IODP) Expedition 398 Christiana, Santorini, Kolumbo (CSK) volcanic field.To understand in-situ stress pressure, we compared preconsolidation (pc) test...
The present study provides additional data on the distributional range of six alien foraminiferal species in living assemblages from Greek coastal areas (Aegean Sea, Eastern Mediterranean). Amphistegina lobiferaLARSEN 1976, Sorites orbiculus (FORSK L 1775) and Coscinospira hemprichii EHRENBERG 1839 are well established areas, whereas Triloculina fichteliana D'ORBIGNY 1839, Planogypsina acervalis (BRADY 1884) Cymbaloporetta plana (CUSHMAN 1924), recorded for first time this paper. occurrence...

Abstract Amphistegina lobifera Larsen is a relatively large (adult diameter ∼1–3 mm), robust, diatom-symbiont-bearing benthic foraminiferal species that thrives in clear, nutrient-poor coastal waters throughout much of the subtropical/tropical Indo-Pacific. Studies late 19th to mid-20th century noted predominance shells and Calcarina Holocene reef sediments, enhanced by hydrodynamic sorting resistance these abrasion. Having migrated through Suez Canal at least 60–80 years before present, A....
Abundances and assemblage composition of benthic foraminiferal, dinoflagellate cysts pollen were analysed together with sedimentological geochemical proxies to investigate paleoenvironmental changes recorded in the Gulf Corinth during MIS 1-5. The is a relatively young (
During the last decades, hundreds of species Indo-Pacific origin from Red Sea have traversed Suez Canal and settled in Eastern Mediterranean. Nowadays, Amphistegina lobifera Larsen, is known to be a successful immigrant that widely distributed coastal ecosystems Mediterranean Sea. most common epiphytic, symbiont- bearing large foraminifer.

The geosites of Lemnos represent local touristic products that, beyond their high aesthetic value, display significant scientific links to the geological past as well prehistory and history, archaeology, mythology religious heritage island. unique wealth in combination with abundance archaeological sites, cultural monuments museums composes basis what we define here “Geo-Archaeo-Routes”: certain routes that can be geographically defined, offered, guided finally followed by masses. outcome...
Abstract. Corfu Island (Greece) is located in the northern Ionian Sea and exhibits unique diverse marine coastal habitats suitable for high-diversity assemblages such as shallow-water foraminifera. The island also lies near current range expansion front of invasive species Amphistegina lobifera. We analyzed foraminiferal 51 samples from 25 sites around island, calculated diversity indices, community structures comparison to local environmental variables. In addition that, using spatial...
The Saronikos Gulf, including the industrial zone of Elefsis Bay, is subjected to a variety urban and impacts that significantly contribute environmental degradation. Benthic foraminifera comprise significant component meiobenthic communities they are widely used as reliable indicators for determination natural anthropogenic impact in shallow coastal systems. present study analyses living benthic composition its relation parameters such grain size, organic carbon content, heavy metal...
A natural pH gradient caused by marine CO2 seeps off the Methana peninsula (Saronikos Gulf, eastern Peloponnese peninsula) was used as a laboratory to assess potential effects of ocean acidification on coccolithophores. Coccolithophore communities were therefore investigated in plankton samples collected during September 2011, 2016 and March 2017. The recorded cell concentrations up ~50 x103 cells/l, with high Shannon index 2.8, along from 7.61 8.18, values being occasionally <7. Numerous...
