Underwater Acoustics: An Invaluable Tool for Cetacean Conservation

The sea gives out the illusion of a serene place to either relax or work in. The tranquility of the sea depth is what most of us expect to hear and see. However, the open seas are realistically noisy and contaminated. Archipelagos Marine Mammal team is working to prove how noisy the Aegean Sea and

Extensive Monitoring of Whale and Dolphin Populations

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

Observation and Monitoring of the Mediterranean Monk Seal around Samos Island

The Mediterranean monk seal (Monachus monachus) is the rarest species of marine mammal in Europe with only around 500 individuals surviving in the world. They are currently listed as “endangered” on the IUCN (International Union for Conservation of Nature) Red List. With such a small remaining population, the actions for their monitoring and conservation are

The Influence of Environmental Factors on the Spatial Distribution of Dolphin Populations in the Aegean Sea

Due to the large biodiversity of cetacean species inhabiting its waters, the Aegean Sea is considered an incredibly important marine area. Archipelagos Institute is conducting a study about the influence of environmental factors on the spatial distribution of dolphins. In particular, this study is focused on two dolphin species that are facing a dramatic population

Development of a Spatio-Temporal Model as a Prediction Indicator of Cetacean Strandings in the Eastern Aegean Sea

Numerous reasons are known as to why marine mammals strand, however, unfortunately it would seem the case that human activity is be a key contributor to these deaths. Data has been collected by the Archipelagos Institute of Marine Conservation ranging from 1994 to the present day, incorporating factors such as seasonality, cause of death, condition

Eco-Navigation: A Citizen Science Platform for Sailors and Sea Enthusiasts to Report Their Observations

Eco-Navigation is a key action developed by Archipelagos Institute, aiming to increase awareness but also public engagement on the biodiversity and conservation of the Mediterranean Sea. Eco-Navigation aims to record valuable data, through reported sightings by sailors and sea enthusiasts on their observations of rare and protected animals such as marine mammals and turtles,  or

Quantification of Microplastics in Dolphin Digestive Systems

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

Behaviour of Delphinus delphis and Tursiops truncatus around Samos Island

Ship traffic has been increasing in the oceans in recent decades, especially in the northern hemisphere, and very likely will increase exponentially in the future. Anthropic activities  produce diffuse and almost continuous noise that may affect very wide areas. Low-frequency (below 1,000Hz) ambient noise levels generated by ship traffic have increased in the northern hemisphere

Eco-Navigation: A Citizen Science Project

Archipelagos’ Eco-navigation project focuses on creating a citizen-science platform about observations of marine mammals (dolphins, whales, seals), sea turtles, invasive species and jellyfish blooms, as well as pollution incidents (plastic debris, oil slicks, etc.) or other unusual sightings. In this way we are in the process of forming a network of sailors, divers, fishermen and

Monitoring Strandings of Marine Mammals and Turtles

The Archipelagos Marine Mammal Research Team has collected for over 15 years, data from stranded marine animals including sea turtles (Caretta caretta), dolphins (Stenella coeruleoalba, Delphinus delphis, Tursiops truncatus), and monk seals (Monachus monachus) from various areas of Greece. The aim of this work is to determine potential hotspots in the Greek Sea and then
