CEN - Center for Earth System Research and Sustainability

  • New building KlimaCampus

    ... brings together the expertise of nine university institutes and facilities: Members include oceanographers, meteorologists, marine biologists, geophysicists, geologists, soil scientists, geographers and biogeochemists, as well as researchers in the business and social sciences. The CEN research center is part of the MIN Faculty and a member of the KlimaCampus Hamburg.

    Institute of Hydrobiology and Fisheries Sciences

    Researchers in Hamburg have done the math: If fishing in the Baltic Sea continues at the same level as in the past few decades, then even without the effects of climate change there will be only very few codfish in the Baltic in the middle term. As such, adequate sheltered areas for young fish and effective limits on maximum catch are essential.

    Climate governance

    Center for Globalization and Governance

    In an attempt to cut emissions of environmentally harmful carbon dioxide, international trading systems for emissions permits have been established. But why aren’t these systems more effective? Sociologists and political scientists are working together to identify concrete new strategies.

    Institute of Geophysics

    Volcanic eruptions can spark climate change: Sulfate aerosol layers can cool the atmosphere, while ash rains fertilize the seas. Here the researchers’ goal is to be able to better predict these eruptions’ effects on the climate.

  • Workers in the rice field

    Rice cultivation

    Research Unit Sustainability and Global Change

    How should farmland be used in the future? What are the arguments in favor of biofuels – and those against them? Can business, climate protection and social justice all be reconciled? At the Research Unit Sustainability and Global Change, researchers from various disciplines work together to find solutions.

  • Buoy in the ocean

    Institute of Oceanography

    Large spherical buoys ‘anchor’ measuring equipment at different ocean depths. After roughly two years, they are recovered and the recorded data is analyzed. How warm is the ocean, and how large is the salinity? What currents are there? Simulations show how the ocean transports heat and energy around the planet.

    Institute of Geography

    How will climate change affect at-risk regions? Researchers are using the example of the Okavango Delta to develop future scenarios for land use in Africa. Combining on-location studies with analyses using geo-software of their own design, they are working to determine how many people the region will be able to feed in the future, and under which conditions.

  • Sediment layers

    Geological Institute

    Sediments hold vital clues to the history of our planet: How have climate conditions changed over the millennia? With the help of these historical archives, researchers can differentiate between naturally occurring and anthropogenic influences.

  • Field research in Siberia

    Institute of Soil Sciences

    Braving temperatures of minus 30 degrees Celsius, a researcher from the Institute of Soil Science examines the soil of the Siberian tundra. These permanently frozen soils are enormous carbon reservoirs. If they continue to thaw as a result of global warming, considerable amounts of greenhouse gases will be released into the atmosphere.

  • Precipitation over Hamburg

    Rain Radar

    Meteorological Institute

    Four high-resolution radar stations have been installed around Hamburg, measuring and transmitting the latest precipitation every 30 seconds and with an accuracy of up to 60 meters. This information can be used to predict flood risks and to provide researchers with key information on water cycles and the exchange between land and atmosphere.
