Marine Mammals & Sea Turtles

Conservation & Monitoring

Overview

Marine mammal research and conservation has been a key area of focus for Archipelagos Institute since its establishment. Work in this field aims to fill important knowledge gaps on the population distribution of marine mammals, whilst also recording and understanding the key factors that impact the survival of these populations, of rare and endangered species. Key factors that we assess include fisheries interactions, depletion of prey stocks, shipping traffic as well as pollution (plastic, chemical and noise pollution). The close cooperation with the local communities and authorities in all phases of this research and conservation is a key asset contributing to their protection.

The North-Eastern Mediterranean hosts some of the most important remaining marine mammal and sea turtle populations in the Mediterranean Sea. These include 4 species of dolphins (bottlenose, common, striped and Risso’s dolphin), 2 species of whales (sperm whales and Cuvier’s beaked whales), the highly endangered Mediterranean monk seal, as well as two species of sea turtle (loggerheadand, green turtle). Despite the international and national legislation  on these species, there is a clear lack of effective conservation actions, causing further threats. Archipelagos’ research and conservation work on marine mammals of the NE Mediterranean with a focus on the Aegean Sea aims to improve the implementation of conservation actions in order to lasting reduction to the threats impacting these charismatic species

Research & Conservation Actions

Cetacean distribution studies on boat-based surveys

Knowledge on abundance, trends and distribution of cetacean population is needed to increase marine conservation efforts, ecosystem models and spatial planning. Boat-based surveys, conducted along pre-designed transects with dedicated observers, are used to assess the cetacean occurrence and density over our study area area.

Bioacoustics monitoring and recording of the communication of cetacean species

Bioacoustics study is essential to understand the different functions of cetacean  communication combined with the influence of anthropogenic activities. The study is carried out using a Hydrophone Array System and PAMGuard Software to detect the presence of cetaceans and to study their vocalizations. At the same time anthropogenic noise pollution is assessed in order to investigate possible effects of marine traffic and other forms of underwater noise pollution on cetacean behaviour and habitat selection.

Behavioural study on marine mammals

The analysis of specific ethograms based on the data collection during boat-based surveys is conducted parallel to other research to better assess the ecology of marine mammals. Statistical analysis and the use of innovative software such as BORIS are helping us to identify and quantify the influence of human activities on the life of marine mammals and to map their habitats (the sites they use for feeding, resting, nursery,, etc.).

Movement pattern, residency pattern and social structure through mark recapture photo-identification techniques

The research enables a census of the presence of a population in a specific area, while also helps in creating a Photo-ID catalogue for each year.The Capture-Mark-Recapture is considered a useful tool for making abundance estimates. During the boat-based survey, dedicated observers are taking picture of specific anatomical parts of the dolphins sighted in order to capture identificationmarks such as patch on the dorsal fin, notch, scars, etc.

Assessing fishstock biomass to estimate prey availability

Archipelagos’ marine mammal research team is currently working to develop a protocol for the estimation of cetacean prey availability, combining data of marine mammal abundance and distribution with data originating from a fishstock biomass scanner.

Aegean Marine Life Sanctuary

The Aegean Marine Life Sanctuary (AMLS) is a model sanctuary where expert care and rehabilitation will be provided to sick and injured marine animals in and around the Greek islands and formerly captive dolphins can thrive in a natural environment. The AMLS is currently under construction on the island of Lipsi, aiming to become the first of its kind sanctuary using the highest standard of animal welfare and serving as a research and educational facility, that allows study without human disturbance to the animals.

Located in a pristine natural location being cost-effective, sustainable, innovative and far from the impacts of humans the AMLS is a solution to a global problem that is replicable and scalable.

Monitoring the Mediterranean Monk Seals

As the Eastern Aegean region is considered a key habitat for the Mediterranean Monk Seal, Archipelagos is carrying out research on this important endangered species. The research is conducting by citizen science awareness and information campaigns, habitat suitability and identification as well as land survey to monitoring the behaviour of spotted individuals. Their interactions with fishing communities, as well as other threats,is monitored in order to develop and enforce realistic conservation and urgently needed schemes.

Archipelagos Stranding Response Network

Over the last decade, the Archipelagos Stranding Response Network has been developed with the cooperation of local communities in the Aegean Islands. It helps providing first aid and rescuing of stranded and, entangled animals as well as data sampling during necropsy on dead animals. The strandings are assessed by qualified staff able to provide guidance also from distance to people reporting the events.

Microplastic/Macroplastic: marine litter monitoring and assessment 

The microplastic research, conducted by Archipelagos Team, is focused on the quantification and categorisation of microplastics in the marine environment. To get a better picture of this global issue, marine animals from different level of the food chain are analysed starting from invertebrates up to megafauna (dolphins, seals, sea turtles found stranded). Furthermore, a parallel microplastic analysis focuses on the measurement of its concentration in both sea column and freshwater, as well as its effect on marine fauna and human's health.

 

The macroplastic research consists of daily and seasonal beach clean ups around Samos island, as well as in other Aegean islands. Moreover, during the boat-based and ferry fixed-transect surveys, a floating marine litter monitoring is conducted. This research can give us the chance to assess the origin of the plastic pollution identifying the seasonal trends and distribution of human litter. In this way, we can be able to realise targeted awareness campaigns to involve locals and tourists adopting conservation strategies to mitigate the problem.

 

Eco-navigation: a citizen-science platform for sailors and sea enthusiasts to report their observations 

Eco-navigation is a a citizen-science platform that addresses to sailors, divers, fishermen and sea enthusiasts and in general people who love the sea. It aims to encourage them to report their interesting observations while at sea such as the observations of marine mammals (dolphins, whales, seals), sea turtles, sharks, invasive species and jellyfish blooms, but also pollution incidents (plastic debris, oil spill, etc.) or other unusual or interesting sightings. The information they gather is made available to expert scientsts throughout Europe, strengthening in this way the cooperation between active citizens and scientists for the conservation of our seas but also for covering the large knowledge gaps that still exist in relation to marine life. 

Citizen science and School education and awareness projects

The Archipelagos’ team is active in various parts of the Aegean region, involving and engaging the island communities in its research and conservation efforts.  A wide variety of media material is produced to raise awareness, including leaflets, posters, booklets, children’s fairy tales, educational games and DVDs. Various events to raise awareness, such as workshops and conferences, also take place in island schools and communities throughout the year. For Archipelagos, this important investment is the key to long-term protection of the Greek seas and the entire Eastern Mediterranean.

A few decades ago the common octopus (Octopus vulgaris) was very abundant in the Greek seas, today overfishing has caused a severe decline to their populations.
According to Greek legislation, the minimum legal fishing size for a common octopus is 500gr; however, the proposed minimum sustainable fishing size is 1100-1300gr.
Therefore, in order to be consumed sustainably, without impacting the stock, it is important to select octopus that are over 1300gr in weight. Additionally, by avoiding fishing and consumption during the main breeding season (April- May), stocks of this species can be naturally enriched and continue to exist in the coming years!

A hopeful image we have recorded at 96 meters depth. In regions where human activity is limited, ecosystems still thrive!
We cannot know or comprehend what are the consequences nor how many decades are required for recovery after the unfortunate destruction these sensitive ecosystems have faced. Therefore, Archipelagos Institute continues the push for legal establishment of a depth limit below which humans do not have the right to overexploit marine resources.

Καλό μήνα και καλό υπόλοιπο διακοπών σε όσους βρίσκονται σε θάλασσες και σε βουνά. 
Διαπλέοντας διάφορα μέρη του Αιγαίου, βλέπουμε σκάφη κάθε τύπου - ταχύπλοα, φουσκωτά, βάρκες - να προσεγγίζουν ακόμα και τις μικρότερες ακατοίκητες νησίδες, συχνά με μεγάλη ταχύτητα και οχλαγωγία.
Υπενθυμίζουμε ότι στις ελληνικές θάλασσές δεν υπάρχει καμία νησίδα, από την πιο μικρή έως την πιο μεγάλη, που να είναι ακατοίκητη ή έρημη. Ακόμα και η μικρότερη νησίδα, πέρα από τα μοναδικής αξίας γεωμορφολογικά στοιχεία, αποτελεί καταφύγιο, από την ανθρώπινη όχληση, για σημαντικά είδη πανίδας και χλωρίδας.
Η όχληση που πολλές φορές προκαλείται - ακόμα και μη ηθελημένα - από όσους επισκέπτονται αυτές τις δυσπρόσιτες περιοχές των θαλασσών μας μπορεί είναι έντονη ή και επιβλαβής για τα είδη που πρέπει να επιβιώσουν εκεί όλο τον χρόνο. Η ζωή στις μικρές νησίδες θα πρέπει να συνεχιστεί και μετά το τέλος του καλοκαιριού.

We wish a good month to everyone and happy holidays to those on vacation at the seaside or in the mountains. 
As we sail across different parts of the Aegean we see boats of different types such as speedboats, rubber boats and boats approaching at great speed and with great uproar even the smallest uninhabited islets. 
We’d like to remind you that in the Greek seas none of the islets, from the tiniest to the largest, is uninhabited or desolate. Even the smallest one has geomorphological elements of great value and are a shelter from human disturbance, for important flora and fauna species.
The disturbance that is often caused - even unintentionally- by those visiting these hard-to-reach areas at the sea can be harmful to the species that try to survive there all year round. Life on the islets must continue after the summer.

Καρχαρίες στις Ελληνικές Θάλασσες #SharkWeek
Καθώς διανύουμε την Εβδομάδα Καρχαριών, είναι μία καλή αφορμή να αναφερθούμε σε αυτά τα ιδιαίτερα είδη. Στις ελληνικές θάλασσες έχουν καταγραφεί 36 είδη καρχαριών, όμως πολύ λίγα είναι γνωστά για τους πληθυσμούς τους. 
Ως κορυφαίοι θηρευτές, οι καρχαρίες παίζουν σημαντικό ρόλο στην διατήρηση της ισορροπίας των θαλάσσιων οικοσυστημάτων και έχουν τον ρόλο του εξυγιαντή των ιχθυαποθεμάτων. 
Η δραστική μείωση των πληθυσμών των καρχαριών λόγω της περαλίευσης και της παρεμπίπτουσας αλιείας μπορεί να έχει δραματικές επιπτώσεις στην θαλάσσια τροφική αλυσίδα αλλά και στα 3 δισεκατομμύρια ανθρώπων παγκοσμίως η επιβίωση των οποίων εξαρτάται από τους αλιευτικούς πόρους. 
Η κατανόηση του πώς οι καρχαρίες κινούνται, συμπεριφέρονται, αναπαράγονται και τρέφονται αποτελεί προϋπόθεση για την προστασία τους. Το Ινστιτούτο Αρχιπέλαγος ξεκίνησε μία νέα ερευνητική δράση για την αξιολόγηση της βιοποικιλότητας των καρχαριών στο Αιγαίο, τόσο στα ρηχότερα όσο και στα βαθιά νερά.

Sharks of the Greek Seas 
As it is #SharkWeek, it is a good chance to talk about this special species. In the Greek seas, 36 shark species have been recorded, however very little is known about their populations. 
As apex predators, sharks play a critical role in maintaining balance in #oceans around the world as they are fed by weak or ill #fishes. However, their numbers are dwindling rapidly due primarily to overfishing and falling victim to bycatch. Their disappearance could trigger widespread trophic cascades and have a great impact on the marine food web as well as on the more than three billion people who rely on the #fishing stock for their livelihoods.
Understanding how #sharks move, behave, reproduce, and feed is essential if we hope to protect them. Therefore, we initiated a project to assess the #biodiversity of #coastal and deep waters shark species in the #aegeansea.
