Marine Mammal Behaviour Research

  The rapid decline of several marine mammal species such as dolphins and whales is a growing problem on a global scale. Losses in abundance have been especially important in the Mediterranean, a biodiversity hotspot which supports a diverse range of marine ecosystems. Marine mammals are threatened by various human activities and their effects, such

Research Expeditions over the Ikaria Trench 

During the research expeditions over the Ikaria Trench, the Archipelagos’ marine mammal team aim to gather data on the species living over this important hotspot, to increase our knowledge on their behaviour, distribution and density. Weather-allowing, boat surveys extend to  further areas during multiple-day research expeditions.  The surveys usually occur between the islands of Ikaria,

Kayak based-mapping of Posidonia seagrass meadows

My name is Liam P. Kennedy. I am from Annapolis, Maryland, U.S.A. and I am currently pursuing my Bachelors in Environmental Studies & Sciences: Geographic Information Systems (GIS) at Towson University. Currently, I am on a summer placement with Archipelagos, from June 2021 until late August 2021. My project at Archipelagos is to create maps

Assessment of microplastic accumulation on Posidonia oceanica seagrass meadows

I’m Imogen, a 22-year-old New Zealand intern currently in the Microplastic and Marine Mammal Team at Archipelagos on Lipsi Island. I am currently completing my masters in Evolutionary Biology via the MEME programme, with the intention to study conservation genetics in combination with field work. While my current study is officially based at Ludwig Maximilian

Photo Identification – An invaluable tool in cetacean research

Photo identification (Photo ID) is a method used within marine mammal research to identify individuals based on photographs. The identification of dolphins is done via the characteristics of their dorsal fins because these are as unique to each dolphin as fingerprints are to humans. The characteristics found on dorsal fins include scars, notches and variable

Great Data from 11 Boat surveys in 15 days by the Archipelagos’ Marine Mammal Research Team

We have recently had the opportunity to reopen our base on the Northern Aegean Island of Samos, which has been closed since the start of the Covid-19 pandemic. This is an exciting change of pace for Archipelagos, as this marine region is a hotspot for many species of cetaceans, creating unequalled opportunities for boat surveys

Bioacoustic Research – Understanding Underwater Sounds

Bioacoustics is a field in biology that studies the way that sound is produced, dispersed and received by animals. Marine mammals are highly reliant on acoustics, due to the low reliability of other available senses, especially sight, in underwater environments. Furthermore, sound travels nearly five times faster in seawater than in air.    Dolphin acoustics

Monitoring Seabird Populations

Besides studying marine mammals and turtles, Archipelagos’ marine mammal team also collects data on the seabirds spotted during boat surveys. The number of individuals, species, and location of encountered seabirds is recorded by dedicated observers. In 2021 only, our team has already recorded more than 3000 sightings! The most common species include the Mediterranean shearwater,

Monitoring Diurnal Variation in Marine Macroinvertebrates

Our names are Irene and Lea. We are both fascinated by the ocean‘s complexity and therefore joined the Archipelagos Institute of Marine Conservation to get an insight into marine biology and conservation. Irene is completing a BSc. in Biology at the University of Sevilla and I (Lea) graduated from the University of Hamburg aftering completing

Comparison of Microplastic Accumulation in Native and Invasive Sea Urchins of the Aegean Sea

There are many problems facing the Mediterranean Sea. We have all heard of the issues with overfishing, warming water temperatures, invasive species, and plastic pollution. But how much do we know? And what is being done about it? Archipelagos is a Greek non-profit organisation founded in 1998, focused on conservation and research in the Aegean
