Scientific breakout sessions

Brief introduction before getting to the breakout sessions

Convener: Maik Thomas (GFZ)

6 Introduction to Scientific Breakout Sessions

Flash-talks with 1-2 introductory slides by the chairs to introduce the breakout session.

7 AMOC variability and North Atlantic sea level

Sea level variations and future rise in the North Atlantic region are related to both freshwater inflow from Arctic regions and the Greenland ice sheet as well as salinity, heat and volume transport variations of the AMOC. This session aims at connecting activities in ST2.1 and 2.3 to find approaches of better estimating the competing (or additive) effects of norther ice melt vs. southern AMOC change.

Speakers: Torge Martin (GEOMAR), Torsten Kanzow (AWI), Henryk Dobslaw (GFZ)

8 Can we get a coherent timeline of Late Quarternary events in the Arctic Ocean?

The reconstruction of conditions in the Arctic Ocean in past cold and warm periods is crucial to our understanding of the sensitivity of the climate system to external forcing. Significant contributions to the subject have come from both AWI and GEOMAR, amongst others. There is large disagreement on dating Arctic deposits, and the field is rapidly evolving with new evidence, new views and new methods. This breakout session would allow a collection of current viewpoints and discuss future collaborative work to identify and address open questions.

Speakers: Walter Geibert (AWI), Robert Spielhagen (GEOMAR)

9 Explainable Artificial Intelligence

We discuss novel methods for explaining the "what, why, and how" aspects of AI decisions.

Speakers: Mike Sips (GFZ), Willi Rath (GEOMAR)

10 Future perspectives in paleoceanographic research from high to low latitudes

Discussion of ongoing and future paleoceanographic and paleoclimatic research foci with particular emphasis on collaborative research between the three centres including topics such as the importance of the Southern Ocean, high/low latitude teleconnections and land/ocean interaction. This will include joint sea going expeditions and any other collaborative efforts such as proxy development.

Speakers: Martin Frank (GEOMAR), Frank Lamy (AWI)

11 Marine Reference Records

In this breakout session we will discuss the potential Reference records proposed within subtopic 2.1 and 2.4. The aim is to define several reference records that also link with the warm climates topic (ST 2.1). We will discuss temporal/thematic foci, sampling, and synergies in order to maximize the benefit of these cores and the choices of sediment cores for the achievement of milestone M2.20-1/2 (ST2.4, marine reference core). Furthermore we will collect expressions of interest by scientists at AWI and GEOMAR and their potential contributions.

Speakers: Florian Adolphi (AWI), Rik Tjallingii (GFZ)

12 Tipping Points - Communication and Research

We recently observe scientific publications on "tipping points" going alongside with increasing attention by the public. The effect on the public assessment of the climate crisis is severe: Tipping points imply an emergency and a point of no return, but in the same time they imply a “safe point” in case of no tipping (neglecting the consequence due to linear changes). Both, the science and communication on tipping points require a scientifically sound and responsible approach. Should we as AWI/GFZ/GEOMAR (Helmholtz?) develop our own strategy on research and communication about tipping points?

Speakers: Maria Hoerhold (AWI), Jan Saynisch-Wagner (GFZ)

16:15 Getting to the guided tours

Guided tour I: Core- and rock repository

The GEOMAR core and rock repositories hold an extensive collection of marine sediment cores and rock samples. The oldest cores of the collection are taken in 1964 in the coastal region of Egypt. Land samples come from Germany, France, central and southern Americas, Iceland, Canary Islands, Kamtchatka, Namibia and from land expeditions affiliated to ship expeditions.

Guided tour II: ARENA 2 Visualization Laboratory

The ARENA (Artificial Research Environment for Networked Analysis) provides visualization services to all scientific disciplines at GEOMAR s well as associated Kiel based marine sciences, with an initial focus on seafloor geology.
