Marine Ecology

Marine Ecology


The Mediterranean is a unique sea with exceptional biodiversity within its waters. Although it represents only 0.8% of the seas worldwide, it supports 7% of all existing marine species. Even though the rich biodiversity spans across the Mediterranean Sea, 25 hotspots have been found in the Eastern Basin alone, which covers the Levantine and Aegean Sea. The Aegean Sea covers an area of approximately 214,000 km2 and holds thousands of smaller and larger islands and islets in its waters. This region comprises one of the most biodiverse areas in the entire Mediterranean and hosts unique ecosystems that have developed over millions of years into a complex web of interdependent species.

Slow growing seagrass meadows provide essential habitats and serve as a nursery for juvenile fish, while invertebrates thrive along macroalgae within the species-rich rocky shores. In deeper waters we are discovering previously unknown coralligenous habitats with incredibly diverse species communities. Hundreds of fish species and thousands of invertebrate species can be found in these extensive areas of priority protected habitats. All of the above highlight the magical world of the Greek seas, but the fact that this biodiversity still survives seems to be purely by luck since few protection or conservation measures are in place. Numerous anthropogenic influences, such as extensive fishing, climate change and the introduction of invasive species threaten to disturb the balance of these biodiversity hotspots. This is a great challenge that all actions of Archipelagos aim to address.

Marine ecology team

With over 18,000 km of coastline and one of the largest fishing fleets in Europe, monitoring of marine activities in Greece is not a simple task. The Aegean Sea supports exceptional biodiversity including rare and protected marine habitats and species. Archipelagos collects data and monitors important ecosystems of the region, assessing habitats and populations as well as their significant by product.  The Marine ecology team consists of a variety of smaller project groups that focus on specific topics to effectively contribute to the overarching goal to provide scientific evidence for conservation efforts. Knowledge acquired in this way enables us to develop successful, targeted management and conservation plans.

Examples of internship projects

  • Assessing the biodiversity of coastal ecosystems with a focus on fish, algae and invertebrates via visual and camera based surveys.
  • Mapping seagrass meadows and coralligenous reefs with participatory GIS surveys and boat-based surveys.
  • Assessing the extent of microplastics distribution on seagrass, sediment, fish and invertebrates.
  • Determining the presence of invasive species, as well as monitoring their distribution and abundance while assessing their impact on native populations.
  • Assessing the impacts caused in coastal ecosystems by anthropogenic influence such as illegal trawling activity and increased sea temperatures.
  • Experimental replanting of Posidonia oceanica seagrass using environmentally friendly and cost-effective methods.


Your role

As a marine ecology intern you will contribute to the conservation efforts by joining one of the project groups in which you are responsible to collect data in the field using a broad variety of equipment and methods as well as the analysis of your data during office work. Since Archipelagos aims to sustain a versatile and up to date overview of the different aspects to the local marine ecosystems, you will be able to gain valuable skills and knowledge in a vast array of subtopics.

Technical skills

At least one of the following requirements is needed:
• Working towards or completion of a relevant scientific degree.
• Experience with snorkeling and free diving.
• Data entry.
• Knowledge in the application of statistics, with some experience in a programming language such as R or Python.
• Good knowledge of the marine environment.
• Experience with scientific surveying.

Other skills

• Fluency in English
• Good communication skills
• Ability to work in a multicultural environment
• Motivation to live in remote places with simple facilities
• Sincere desire to work towards Archipelagos’ conservation efforts

What we offer

We offer an internship at an inspiring institute with experts on coastal conservation. You have the opportunity to collect data for writing a thesis, scientific publications or increasing your skillset within the marine conservation sector. Internships range from 3 - 12 months, although shorter or longer internship periods may be arranged to cover the needs of groups or individuals. As Archipelagos is a non-profit research institute, the internships we offer are unpaid. The experience requires an internship weekly fee of 200 - 245 euros to cover living and research expenses (e.g. housing, 3 meals a day, public liability insurance and other research facilities). Students and recent graduates and researchers are advised to search for possible funding through their universities, by getting in touch with the International Office/ Placement/ Erasmus+ Offices at their Universities or other relevant grant providing organizations in their region.


To apply for this internship, please send an email to our admissions team outlining your program of interest and requesting an application form - admission[email protected]. We will get back to you within 2 working days.
