Mahi Mahi
Mahi mahi – one more invaluable resident of our seas. It is a particularly important species in our waters, as it preys on young silver-cheeked toadfish – one of the most problematic invasive species that are spreading at an alarming rate in the Greek seas. It is therefore crucial to recognize that the overfishing of […]
Turtle (Caretta caretta) information
Our daily companions in the depths of the northern Aegean… For about forty days now, we have been coexisting with this particular loggerhead sea turtle. We always encounter her in Posidonia seagrass meadows, reminding us how vital these forests of the sea are—not only for marine animals, but also for us humans. In these meadows, […]
Cuvier’s Beaked Whale above the Ikaria Sea Trench
Cuvier’s Beaked Whale above the Ikaria Sea Trench The Cuvier’s beaked whale is a truly enigmatic marine mammal. It is one of the least studied cetacean species worldwide, and at the same time one of the most difficult to research, as it systematically avoids contact with boats or humans. Remarkably, unlike the other six species […]
Young Sperm Whale Washed Ashore Dead in Samos
A young sperm whale (Physeter macrocephalus), approximately four meters long and weighing around one ton, washed ashore dead along the northern coast of Samos. Throughout most of the year, this area of the Aegean Sea is one of the most important migratory routes for these giants of our seas. Unfortunately, it is not the first […]
Plastic Pollution in the Aegean
An image of the Aegean in August In waters where humans have exchanged ideas, culture and goods for thousands of years, we are now exchanging plastic waste. It’s rare to find a place where plastic isn’t visible – floating on crystal-blue waters, scattered along shores, or polluting roadsides. But the problem isn’t simply aesthetic. The […]
Risso’s Dolphin monitoring
Risso’s Dolphin: a charismatic species that we have been monitoring for the past few days over the Ikaria Trench — a remarkable underwater canyon reaching depths of up to 1,400 meters. Relatively unknown to the general public, the Risso’s dolphin is the largest dolphin species found in Greek waters, reaching up to 4 meters in […]
Two sperm whales begin a deep dive above the Ikaria Trench
Sperm whales – the giants of our seas. They are some of the most impressive marine mammals we have recorded in recent days with the crew of Triton. They are the largest toothed whales on the planet, weighing up to 50 tonnes and reaching lengths of 16–18 meters. This deep and steep underwater canyon, which […]
Planting Posidonia seagrass gardens
The Archipelagos Institute has continued to add new plants this season to the underwater meadows of Posidonia oceanica, a carbon-absorbing seagrass species. The effort began in 2018 and has continued at an intensive pace annually from early spring through the end of the year, aiming to reverse the ever-increasing destruction of Posidonia seagrass meadows in […]
Planting underwater Posidonia seagrass gardens
This great effort, which began 7 years ago, continues at an intensive pace from early spring until the end of the year. Our goal is to contribute to reversing the ever-increasing destruction of Posidonia seagrass meadows in Greek seas. Since 2018, the Archipelagos Institute has been developing and implementing experimental underwater seagrass planting techniques, in […]
Sperm whale Peloponisos
Sperm Whale sighting off the coast of Astros Kynourias, in the Argolic Gulf. This is the largest mammal species that we have recorded in these deep underwater canyons east of the Peloponnese — an area that remains understudied in terms of marine mammal populations. Notably, the sperm whale is the largest toothed whale in the […]
