“Noise pollution” in the marine environment has been an increasing concern for conservationists and marine researchers in the past decades. Underwater sounds caused by ships have no impact on humans, however, they may have severe effects on marine life, especially marine mammals. Engine noise from boats increases with size, power, load and speed. It
Although people have long been fascinated by the behaviour of animals, the formal discipline of animal behaviour–ethology–is actually relatively new, dating to the work of Konrad Lorenz in Austria in the 1930s. The application of ethological principles and methods to the study of animal welfare is even newer. Behavioural data can offer insight into the
The Aegean Sea supports some of the most important remaining marine mammal populations in the Mediterranean. Archipelagos´ marine mammal research team monitors year round through regular boat surveys the populations of Common Bottlenose dolphin (Tursiops truncatus), Short-beaked Common dolphin (Delphinus delphis), Stripped dolphin (Stenella coeruleoalba), Risso’s dolphin (Grampus griseus) and Sperm Whale (Physeter macrocephalus).

Dolphins might be one of the most charismatic animals that plough through the oceans and seas. In general, they are social animals that enjoy living in pods. These marine mammals are considered one of the most intelligent species on the planet. Although they are mainly piscivores, their diet varies between species, feeding on fish, cephalopods
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
Archipelagos Marine Mammal Team has been monitoring the population of  Sperm Whales (Physeter macrocephalus) in the north Aegean Sea for over 17 years. Physeter macrocephalus is the biggest species of Odontoceti – toothed whales. A female can reach approximately 12 m and the male 18 m in length. The large head occupies one-third of the
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
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 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
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
