This project combines and reconsiders all the available evidence of the Scheurrak SO1, and use new archival databases and modern archaeological techniques to shed new light on the material culture of the Baltic grain trade and the Holland shipbuilding industry at the turn of the sixteenth century.

Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities.

Papers presented at a colloquium, held in honour of Professor Dr. P.J.R. Modderman, Leiden, 3-7 May 1982.

Escalating tensions in South China Sea have epitomized US–China relations for nearly a decade. Warning signs of a possible collision between a rising China and steadfast US, bring to light the need to think about ways that can halt and reverse the intensification of their confrontational moves.

Identifying the gaps in the legal framework for EU activities in the maritime security domain, and specifically in the areas of combating piracy, human smuggling or trafficking and drug trafficking.

What are the capabilities or limitations of traveling between islands and how does this reflect seasonal variation? Is it possible to show higher levels of connectivity between islands based on generated pathways between several sites on two separate islands?

LAPP was invited by the Plastic Soup Surfer to attend the premiere screening of SOURCE 2 SEA, a documentary following the Plastic Soup Surfer on his journey along the Rhine.

Gayathri Jaikamur has been awarded by the Dopper Foundation in the Change Make Challenge. She is a student of Masters Biology (Specialisation: Evolution, Conservation and Biodiversity) from India - working under the supervision of CML-researcher Dr. Thijs Bosker (and co-supervision of Dr. Nadja Brun).…

A fragment of a human skull discovered in sediments extracted from the bottom of the North Sea, 15 km off the coast off the Netherlands, has been identified as belonging to the extinct Neandertal group.

‘Even at the deepest point in the ocean you can still hear the noise from boats,' says biologist Hans Slabbekoorn. ‘And that's while sound is the most important means of communication for underwater life.' What is the effect of all that underwater noise on fish and other animals? Slabbekoorn is on board…

Physicists, including Dorothea Samtleben from Leiden University, are building a giant underwater telescope to unravel the origin of neutrinos and to solve the mystery surrounding dark matter. The first detector has now been installed. Once it is finished, the telescope will be three cubic kilometres…

On 13 June, Jorrit Rijpma spoke on migration and border control at sea at the Summer School “Open Sea on Migrations, Sea Border Control and Human Rights” organized by the Jean Monnet Centre of Excellence on Migrants’ Rights in the Mediterranean based at the University of Naples (“Orientale”).

One of them turned out to be two thousand years old. And older giant barrel sponges appear to have a faster rate of cell division, unlike us. They produce antibiotics and much, much more. Lina Bayona Maldonado studied how the differences in such factors as age or oceanic depth affect the production…

Just off the coast of Libya, aid organisations try to rescue boat migrants. The confiscation of one of the rescue ships shows how important but difficult it is for aid organisations to remain neutral, independent and impartial, says Eugenio Cusumano.

A flint tool covered with a tar-like substance has turned out to be a top scientific find. Research by a Dutch team of scientists showed the find to be a piece of birch tar that was extracted 50,000 years ago by Neanderthals using complex techniques. The tar was used as an adhesive to make it easier…

A fragment of a human skull from the collection of the Dutch National Museum of Antiquities (RMO) and a decorated bison bone, both from the North Sea bed, are rare finds from the end of the last Ice Age. The finds are 13,000 years old and, as such, form the earliest known modern human from the Netherlands…

From 26 to 29 September 2017 the International Conference on Microplastic Pollution in the Mediterranean Sea was held.

Two years after the first conference, the Napels based Institute of Chemistry and Technology of Polymers, together with a consortium of organisations and research institutes, organised the second conference from 15 to 18 September in Capri, Italy.

By comparing the archaeological evidence at Sedgeford and other sites located on both English and Continental coastal zones, what evidence is there for a shared maritime culture between these North Sea communities? Also if evidence is found, can we reveal to some extent a separate coastal identity to…

The Dutch Research Council (NWO) awarded behavioural biologist Hans Slabbekoorn (Institute of Biology Leiden) a grant of 750,000 euros to study fish and sounds around wind farms in the North Sea.

On 20 April 2017 Jorrit Rijpma, Eugenio Cusumano, and Melanie Fink organise a Workshop to discuss the legal and policy implications of the surge in privately conducted search and rescue operations in the Central Mediterranean. The Workshop takes place in cooperation between the Law School and the Faculty…

In otherwise energetic desserts at the bottom of the sea, researchers have found oases where microbes can harvest energy. Remarkably, the microbes first have to be buried under starving conditions for 80,000 years. An international group of researchers, amongst them José Mogollón from the Insitute of…

Over the years, many spectacular archaeological finds have been washed ashore on the Dutch coast. Among these a large assemblage of barbed points made of bone and antler from the Mesolithic (11,000-8000 BC). The species used by Mesolithic hunter-gatherers to manufacture their barbed points remained…

How can mega sand nourishments, such as the Sand Motor, be designed and managed for optimal ecosystem services provision ?

Are there acoustic cues for settlement stage larvae in deep-sea soundscapes around hydrothermal vents?

From the late Middle Ages onwards, maritime conflict has developed hand in hand with international trade. Over time, specific institutions were established to address disputes arising from violence or mishap at sea and in coastal areas. Conflict resolution at sea has mostly been studied through the…

The project 'Policing the high seas: maritime law-enforcement in a multi-actor environment' aims to identify the gaps in the legal framework for EU activities in the maritime security domain, and specifically in the areas of combating piracy, human smuggling or trafficking and drug trafficking.

There is little evidence of the routes connecting Amerindian communities in the Caribbean prior to and just after 1492. Uncovering possible canoe routes between these communities can help to explain the structure, capabilities, and limitations of the physical links in their social and material networks.…
