MARIENE INFORMATIE SERVICE MARIS BV

Their core work

MARIS is a Dutch SME specializing in marine and ocean data management, interoperability, and information services. They build and operate data infrastructure that connects ocean observation networks, research vessels, and environmental monitoring systems across Europe. Their core work involves making fragmented marine datasets findable, accessible, and usable — from bathymetry and coastal observations to deep ocean research data. They serve as a technical backbone for pan-European marine research infrastructures, handling data integration, metadata standards, and cloud-based virtual research environments.

What they specialise in

How they've shifted over time

In the early H2020 period (2015–2018), MARIS focused on ocean observation, Atlantic monitoring, and domain-specific marine data platforms — projects like AtlantOS, ODIP 2, and BASE-platform dealt with sensors, fisheries, climate ecosystems, and bathymetry. From 2019 onward, their work shifted decisively toward research infrastructure integration and EOSC — projects like ENVRI-FAIR, EOSC Future, EGI-ACE, and Blue Cloud reflect a move from sector-specific marine data toward cross-domain cloud computing, FAIR data services, and federated scientific infrastructure. The trajectory is clear: from marine data specialist to European-scale research data infrastructure provider.

MARIS is positioning itself as a marine-to-EOSC bridge, making them a strong partner for any project that needs to connect domain-specific ocean or environmental data into European open science infrastructure.

How they like to work

MARIS operates exclusively as a participant — across all 14 projects they have never coordinated, which is typical of a specialized technical SME that provides essential data services within larger consortia rather than leading them. With 412 unique partners across 55 countries, they are remarkably well-networked for a small company, indicating they are a trusted, repeat contributor that large infrastructure projects actively seek out. Their presence in successive generations of the same initiatives (JERICO-NEXT → JERICO-S3, SeaDataCloud → Blue Cloud) shows consortia value their continuity and institutional memory.

With 412 unique consortium partners across 55 countries, MARIS has one of the most extensive collaboration networks of any marine data SME in Europe. Their partnerships span from coastal observatories to EOSC-scale cloud initiatives, giving them connections across both marine science and e-infrastructure communities.

What sets them apart

MARIS occupies a rare niche: a small private company that has become indispensable to Europe's marine data infrastructure. While many organizations contribute scientific knowledge or computing resources, MARIS brings deep expertise in marine metadata standards, data integration, and interoperability — the connective tissue that makes multi-national ocean data systems actually work. Their dual fluency in marine science infrastructure and EOSC/cloud architecture makes them an unusually versatile partner for any consortium bridging domain science with European-scale data platforms.

Highlights from their portfolio

• SeaDataCloud
  Their largest funded project (EUR 732K), building the pan-European infrastructure for marine and ocean data management — the backbone of European sea data services.
• EOSC Future
  Second-largest funding (EUR 647K) and a flagship EOSC project, showing MARIS's successful transition from marine-only to cross-domain European research infrastructure.
• Blue Cloud
  EUR 533K project piloting virtual research environments for marine research and the blue economy — represents MARIS's work at the intersection of cloud computing and marine science.
