During the COVID-19 pandemic, in an effort to slow down the spread, many countries are applying temporary restrictions on travel from countries outside the EU by closing borders. Some countries have also applied national border closures and/or border checks at their borders or when moving between different regions at the national level. These restrictions are subject to a continuous evaluation of the epidemiological situation by countries and they change frequently.
If you intend to travel in the EU, including Greece and Italy, check the European Commission Re-open EU web platform containing real-time information on borders, available means of transport and tourism services in the Member States (choose the country from the menu available).
Please refer to the dedicated pages for more detailed information about travel, anti-covid measures adopted at Tethys’ projects and useful links

The Tethys Research Institute is a non-profit research organisation supporting marine conservation through science and public awareness, founded in 1986 and headquartered at the Civic Aquarium of Milano, Italy. Tethys’ main goal is the conservation of the marine environment, achieved through the provision of scientific knowledge to conservation policy, the participation in the international conservation process, and public awareness. Over almost three decades of work, Tethys has generated one of the largest datasets on Mediterranean cetaceans and communicated the results of its research in hundreds of scientific publications. In 1991 Tethys was the first to conceive and propose the creation of an iconic protected area, the Pelagos Sanctuary for the Conservation of Mediterranean Marine Mammals, the world’s first to be established beyond national jurisdiction. Since 1987 Tethys has involved thousands of people from all over the world as research volunteers in its conservation activities. Funding to Tethys derive from government and EC grants, private donors, and contributions from research volunteers. The work of Tethys is based on the collaboration of approximately 30 associates and assistants.
Befriend a sperm whale from the Pelagos Sanctuary or donate its friendship to someone you love for Christmas time. With this symbolic gift you will support the research and conservation of Mediterranean cetaceans through the Tethys Research Institute.
