    • 17:00 18:00
      Guided Tours 1h

      Please sign up for one of the three guided tours when you register online to facilitate our planning.

      • Guided Tour 1: Laboratory for Earth Magnetism in Time and Space (GFZ) 1h

        This laboratory deals with magnetostratigraphic dating of paleoclimate archives and the reconstruction of geomagnetic field variation in the geological past as well as with analyses of magnetic minerals.
        - Determination of intensity and directions of sedimentary magnetizations
        - Characterization of magnetic minerals by their physical properties, such as coercivity, Curie-temperature, grain size, and concentration, as well as by their chemical composition and preservation status

      • Guided Tour 2: Gravity Observations on Telegrafenberg (GFZ) 1h

        During this guided tour, we will first visit the Satellite Laser Ranging (SLR) Station of the GFZ Potsdam, which has been continuously operating within the framework of the International Laser Ranging Service (ILRS) since January 2003. Further, a short walk will bring us to the life-size GRACE satellite models displayed in the park. Since 2002, the mission has provided invaluable insights into the Earth's water cycle. The tour will end in the historical Pendulum Hall. Between 1898 and 1904, the absolute determination of the Earth's gravity using reversion pendulum measurements was carried out here by Friedrich Jakob Kühnen and Philipp Furtwängler (Geodetic Institute).

      • Guided Tour 3: The Great Refractor 1h

        The "Great Refractor" is the world´s fourth largest refracting telescope, which was completed in 1899. This telescope bears tremendous witness to the optical precision manufacturing and early astrophysical science taking place at the turn of the 19th/20th century.

      • Guided Tour 4: Isotope & DNA Laboratory (AWI) 1h

        The ISOLAB facility of the AWI in Potsdam develops and utilizes stable H, O, C, N isotope methods to decipher Quaternary environmental change on in polar regions of both hemispheres.

        Turquoise Transitions: Sustainable Ocean Use and Blue-Green Innovation 45m

        How can we advance sustainable ocean use that contributes to climate mitigation, adaptation and ecological conservation?
        How can we transfer findings from ocean science into transformative application?
        What transition pathways can we identify for current, often unsustainable, ocean use by sectors such as tourism, fisheries, energy, water and transport?
        How can coastal regions provide for long term sustainable development, decarbonise marine transport and infrastructure and scale marine renewable energy?
        Can sector-coupling and technological innovation help accelerate required transitions?
        The session will discuss potential innovation strategies for a sustainable blue-green economy.

        Breakout 1: Paleoceanographic research 1h 45m

        One "paleo session" with topics such as paleo-climate, southern ocean, arctic chronologies and reference cores.

        Speakers: Martin Frank (GEOMAR), Frank Lamy (AWI), Florian Adolphi (AWI), Cecile Blanchet (GFZ), Rik Tjallingii (GFZ)
      • 09:30
        Breakout 2: Sea level: bridging the scales between remote forcing and coastal impacts 1h 45m

        We would like to take a look at fingerprints of sea level change (e.g. related to ice sheets, AMOC, etc) and their manifestation along the ocean margins.

        Speaker: Torsten Kanzow (AWI)
      • 09:30
        Breakout 3: From data to products - needs & barriers 1h 45m

        Scientists often produce data products as part of their research, e.g. ocean state indicators from time series data or via gridded fields.
        It is of interest in Topic 2 to discuss how disclosure and access to such data products is achieved, what limitations exist and how access can be improved. The discussions are linked to milestones and results of PoF IV.

        Speakers: Johannes Karstensen (GEOMAR), Wilken von Appen (AWI)
      • 09:30
        Breakout 4: Changing surface accumulation in Antarctica 1h 45m

        Surface mass balance in Antarctica has been changing. The East Antarctic Ice Sheet became a mitigator of sea level rise. The beakout session will discuss our state of knowledge from observations and models, identify needs and present eventually where research efforts should be focused on for the remainder of the PoV IV period.

        Speaker: Olaf Eisen (AWI)
      • 09:30
        Breakout 5: Harnessing AI for Climate Science 1h 45m

        Recent years have seen significant advancements in climate science through the use of AI, including machine learning models that outperform traditional weather forecasting methods, automated analysis of vast amounts of satellite data, and the exploration of data-driven insights into climate processes. In this breakout group, we will discuss the current applications of AI in climate science within Topic 2, explore new directions, and foster interdisciplinary collaborations.

        Speakers: Nikolay Koldunov (AWI), Nils Hutter (GEOMAR)

        Breakout Session 6: Picturing our Future in a 2.5 degree world 1h 45m

        While we are all familiar with physical maps projecting temperature changes by 2100, imagining the possible implications of these changes is challenging. Do they signal a significant risk for civilization, or a future where challenges that already exist, like heatwaves, become more intense or frequent but yet manageable through adaptation?
        Climate science struggles not only with estimating probabilities but also with effectively communicating them, especially when it comes to low-probability, high-impact events or slow-moving yet inevitable processes. Equally important is moving beyond the current one-way communication. What kind of information is actually needed for society to understand and relate to the problem? What kind of information is needed for decision-makers to take action, why is taking action and decision making in itself a complex field? How can there be better "integration" and effectiveness of climate science for society?
        “Picturing Our Future” seeks to establish a scientific approach that goes beyond one-way communication and includes diverse stakeholders, forming evidence-based images and communication strategies to support decision making in the climate crisis.
