Ocean Science exhibition

The Ocean Science Multimedia Exhibition on the Cap San Diego in Hamburg was one of the first public events within the framework of the UN Decade of Ocean Science for Sustainable Development in Germany and is supported by more than 75 partners and stakeholders.

The Ocean Decade is a unique opportunity for ocean stakeholders from around the world to come together to share knowledge and foster partnerships needed to support a well-functioning, productive, resilient, sustainable and inspiring ocean. The exhibition aims to visibly support the goals of the Decade. The exhibition will serve as a learning space for all Hamburg schools, as the combination of multimedia installation, the exhibits and the possibility of discussions on stage will create an attractive extracurricular program.

In addition to the two world premieres of the microplastic collector, a project funded by the German Federal Ministry for Economic Affairs and Climate, and the first research diver-guided underwater satellite, the exhibition features an Argo Float, one of the 3,000 state-of-the-art measuring buoys currently deployed on the ocean, and an active algae reactor from the University of Hamburg as a symbol of the extraction of future food and energy from the ocean. Also on display is one of the first automatic measuring stations for ships, the OceanPack™ from the Kiel-based company SubCtech, which is also used by professional sailor Boris Herrmann from Hamburg on board his IMOCA racing yacht Malizia Seaexplorer. A historic Swedish sea mine and art made from ghost nets by the Hamburg start-up Bracenet, together with a current documentary on the salvage of munitions in the Baltic Sea, bring the topic of marine litter to life. A touch table from the German Ocean Foundation provides visitors with information on the Ocean Decade and they can watch films of all 80 expeditions of the German Ocean Competition on board the research vessel ALDEBARAN, from which a historical weather station is also on display.

Since 2003, the Cap San Diego, the world's largest seaworthy museum cargo ship, has been a maritime monument and floating hotel, now moored at the Überseebrücke in Hamburg. The exhibition takes place in the freighter's former sweet oil tank and hold and consists of a multimedia show on five large video screens and selected exhibits. The Ocean Science multimedia exhibition will be on display on board for the entire duration of the Ocean Decade.

This exhibition is powered by solar energy to protect our oceans - with the support of a photovoltaic system installed by Meyer Burger on the deck of the Cap San Diego - making it the first exhibition in Hamburg to rely solely on self-generated solar power.

Discover the exhibits:

  • Planblue

    Underwater satellite - First diver-guided model of an underwater satellite

    Planblue has developed the first underwater satellite that can automatically scan the seabed in great detail. In the future, it will be possible to show how much CO2 is fixed on the seabed (the seabed can fix CO2 20 times more efficiently than on land), how healthy (e.g. pollution, climate change, diseases) and how species-rich (e.g. loss of species, visualization of the success of environmental measures) the seabed is - the first diver can see this.

  • OceanOPS

    Argo Float measuring buoy - measurement of temperature and salinity profiles in the ocean

    Model of an Argo float for measuring temperature and salinity profiles in the ocean. The buoys drift freely with the ocean current at a depth of 1,000 m and regularly rise to the surface to transmit measurement data and their position.

  • Toxicological Institute of the University of Kiel

    Sea mine (marine litter) - Anchor mine from Sweden, produced and used from 1918 to 1972 (Toxicological Institute of Kiel University, Ministry of the Environment Schleswig-Holstein, Digital Ocean Lab, Fraunhofer ICT, GEOMAR, HELCOM, Aarhus University, IOPAN).

    An anchor mine from Sweden, manufactured and used from 1918 to 1972. The total mass is 303 kg, of which 50 kg is explosive and 168 kg is anchor steel. The anchor line has a total length of 130m. Ammunition parts look very different after more than 70 years in the sea. Only the explosive ordnance disposal experts of the responsible state authority can really recognize and officially assess the danger.

  • Bracenet

    Art from ghost nets - salvaged abandoned fishing nets

    Around the world, 250 divers are out in the wind and waves to recover more and more ghost nets. Over 773 tons have already been recovered - roughly equivalent to the weight of 6 blue whales. The ghost nets are then used to make various products in Hamburg, such as bracelets, dog leashes and the like.

  • SubCTech

    Automated ocean laboratory, OceanPack™ - mobile automated laboratory for ships

    OceanPack™ is a mobile automated laboratory for ships. It can provide unattended climate measurements in the water for science.
    It has integrable sensors for: CO2, salinity, temperature, algae types, pH. The data is used as a weather station and for ocean current models to calculate global energy transport. The technology is now so advanced that racing yachts such as Boris Herrmann's Malizia have a miniaturized device on board.

  • University of Hamburg

    Algae photobioreactor - Tubular algae reactor for the production of algae biomass

  • HelioRec

    Floating solar power plant (premiere) - Floating wind and wave-resistant solar technology

    A wind and wave resistant floating solar technology. It transforms unused water surfaces into a home for clean energy generation with customizable technologies for different applications. Experts design exclusive floating solar systems that meet individual requirements.

  • The SeaCleaners

    Manta - model of an ocean-going catamaran that will clean up the oceans from 2026

  • PlamoWa

    Microplastic measuring device - Automatic microplastic sampler with ultrasonic pre-filter (Nägele Mechanik, 4h Jena Engineering)

    The first and so far probably only automatic microplastic sampler with ultrasonic pre-filter developed by a consortium of the companies 4H Jena and Nägele Mechanik in 2018 with funds from the Central Innovation Program for SMEs of the Federal Ministry of Economics.

  • Historical weather station

    Historical weather station - used on the research and media ship ALDEBARAN - mainly in shallow water areas

    Historical weather station from the Norwegian company Aandera used on board the sailing research vessel ALDEBARAN from 1992-2005. The ALDEBARAN is on tour in shallow water and coastal areas, but also in inland waters and rivers. Today, the station has been replaced by an official weather station of the German Weather Service.


  • German Marine Foundation

    Interactive touch table - expedition films from the federal marine competition "Research at Sea" and information about the work of the German Marine Foundation

  • Aquazoo Löbbecke Museum

    Northern gannet - specimen of the seabird building a nest with plastic parts
