Common dolphin (D. delphis) bioacoustics project – a study about vocalization and sociality of the common dolphin population in the Aegean Sea, February-March 2018. Common dolphins often live in pods consisting of around 12-20 individuals in the Mediterranean Sea (Murphy et al., 2008). The population of this particular species has been declining at an alarming
  Mankind is having a major impact on every ecosystem on earth. From the very tops of the tallest peaks to the deepest abysses in our oceans, the world is changing, and how we measure these impacts, is also changing. Bioindicator species are helping us understand how we have affected our world and can even
Microplastics content found in edible fish and invertebrate species of the Eastern Aegean Sea, February 2018 The increasing abundance of marine plastic debris is a worldwide issue and it represents a critical threat in areas such as the Mediterranean Sea. Many studies so far already documented the negative effects of this global issue on marine
Echinoderms play an important role in marine, benthic ecosystems. They can be both carnivorous or, most importantly, grazers. The grazing of sea urchins specifically reduces the rate of colonization on bare rocks by settling organisms. This keeps algae in check, thereby enhancing the biodiversity of coral reefs. Despite that, echinoderms sometimes have large population swings

The ideal weather conditions allowed the Archipelagos Marine Mammal Team to carry out an extensive survey in the waters north of Samos and Ikaria Islands during the past week. The Team spent several days in the sea with the aim to have an updated census of the cetacean species present in the study area. At the
The Joint Educational Oceanographic Research Course of the University of Essex UK with the Archipelagos Institute, took place in the marine area between Samos and Ikaria islands. For one week, with parallel recordings by Archipelagos’ 3 research vessels, with the aid of contemporary research equipment, the final year students of Marine Sciences from Essex university,
The Marine Conservation Team of Archipelagos Institute has started to use marine bioindicator species to monitor ecosystems of the littoral zone. Bioindicator species are species which only can sustain within high quality environmental conditions. The use of Bioindicator Species is becoming of increasing importance as they can tell us more about the cumulative effects of
The long-term macroplastic monitoring project began in early June 2017 and has since been carried out almost daily in two beaches of SE Samos. Every weekday, two members of the research team go to the sites to collect all the debris left by the public and washed in by the sea. All the collected debris
Posidonia oceanica is an endemic seagrass species in the Mediterranean Sea. It has a key ecological role and many impacts on its ecosystem. Its role in fisheries production and in sediment stabilization are well-known. In fact, seagrass meadows provide habitats for a number of threatened species. However, throughout the Mediterranean these meadows are declining at
