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
The Ocean Acidification (OA) problem is referred to a reduction of the sea water pH caused primarily by the anthropogenic increasing uptake of CO2 from the atmosphere. There is a direct relationship between atmospheric CO2 and ocean pH: as CO2[atm]-uptake increases, the pH drops. Industrial activities have resulted in an increase in atmospheric CO2 concentrations
With climate change and ocean acidification of the seas, more alien species are spreading in our seas. The green macroalgae, Caulerpa cylindracea, is considered an invasive species native from Australia that has rapidly spread across the Mediterranean since 1926. C. cylindracea colonises a variety of substrata, and its dominating presence has been found to alter
With the worldwide increase in the production of plastics over the last century, in combination with the overall lack of plastic waste management, the impact of plastics on marine environments has become a critical concern. Microplastics develop from the degradation of larger plastics, such as plastic bottles, bags, and many other improperly discarded objects, that
Since the opening of the Suez Canal between the Red Sea and the Mediterranean Sea there has been a steady flow of invasive species entering the Aegean Sea out of which there are over 32 established fish species. At Archipelagos Institute we are monitoring the spread of these species in the region of the NE
