Welcome to the annual meeting of Topic 2!

"Networking, Collaboration and Hot-Science" – this is the motto of the annual Topic-2 meeting in 2022. More than 50 scientists will meet “live” in Bremerhaven to intensify the scientific collaboration between the three centers AWI, GEOMAR and GFZ. The agenda offers plenty of space for a creative "think tank" as well as for socializing in a relaxed atmosphere.

Columbusstraße 65
D-27568 Bremerhaven

14:10 Coffee break

Breakout session (A): Scientific breakouts I

Getting to the breakout sessions

6 A1: Observing and Modelling the Atlantic Meridional Overturning Circulation (AMOC) (past/future 50 years)

We will discuss the current state of observing systems and modelling activities to study the AMOC, and evaluate the potential for joint analyses, publications and projects. The focus should be on the monitoring and understanding of the variability of the past 50 years and the projection of the next 50 years, in particular the detection of (anthropogenic) trends within the range of natural interannual-decadal climate variability.

Speakers: Prof. Arne Biastoch (GEOMAR), Prof. Torsten Kanzow (AWI)

7 A2: Land-Ocean interaction and high-resolution climate archives

We will discuss the potential to build collaborative projects to explore the relationships between the terrestrial and marine realms. Some of the focuses for this breakout sessions will be, for instance, the linkages and feedback processes between sea surface temperatures, ocean circulation, rainfall, weathering and erosion during warm and cold periods of the Quaternary. It will be also of prime importance to determine how to exploit our modelling and proxy-data expertises in topic 2 to tackle these challenges. Time-scales and regions of interest can be defined in the group.

Speakers: Dr Cécile Blanchet (GFZ), Dr Rik Tjallingii (GFZ)

8 A3: Regional versus global: How to connect the polar regions to the global climate system - low and high-latitide linkages

We aim to discuss advective pathways and consequences of increases in polar freshwater export (Arctic Ocean, Greenland and Antarctic ice sheets) under global warming. While typically discussed in a regional context, climate change in high latitude oceans will affect the global ocean circulation, deep as well as intermediate water formation, gyre-gyre interaction and thuscinterfere with internal variability of the subpolar to subtropical regions.

Speakers: Benjamin Rabe (AWI), Dr Torge Martin (GEOMAR)

9 A4: Identifying major shortcomings in ESM: Where do we need to put our focus?

We will discuss ongoing work to identify biases in coupled models. Which processes or regions are poorly represented? Where has there been significant improvement and where do we need to focus our efforts in the near future? Higher resolution? More parametrizations? Better parametrizations?

Speakers: Prof. Joakim Kjellsson (GEOMAR), Dr Sebastian Wahl (GEOMAR)

Breakout session B:: Scientific Breakouts II

Getting to the breakout sessions

17 B1: Earth System thresholds affecting globally relevant CO2 sinks and sources

Our Program lists the implementation of a Cross Topic Activity on “Earth System thresholds affecting globally relevant CO2 sinks and sources” as deliverable. Here we would like to discuss how this could be addressed:
- Which thresholds and tipping points will we focus on?
- Which experts should be brought together?
- Which expertise is missing?
- Which strategies are most effective to reduce carbon dioxide emissions at scale?
- Which land and ocean carbon dioxide removal approaches are effective and safe to implement at scale?
A goal of this discussion is to identify a responsible team and develop a strategy for a scoping workshop for the CTA.

Speakers: Prof. Gesine Mollenhauer (AWI), Prof. Jelle Bijma (AWI), Dr Mar Fernéndez-Méndez (AWI)

18 B2: Greenland ice-sheet retreat: reasons and consequences

The Greenland ice sheet is increasingly losing mass. In our centers various activities are under way regarding the quantification of the causative processes (e.g., surface melt, ice-sheet dynamics, ocean-ice interaction) and the assessment of the multiple consequences, such as changes in sea level, ocean stratification and deep-water formation. Based on these activities the goal of this breakout session is to identify concrete opportunities to strengthen cross-center collaborations utilizing our complementary expertise, datasets and methods.

Speakers: Prof. Maik Thomas (GFZ), Dr Torge Martin (GEOMAR)

19 B3: Small-scale processes & upwelling in a changing world

We want to discuss fine scale processes in the upper ocean and how information from in-situ observations, satellites, and models can be best combined. Particular focus will be on the mixed layer, frontal dynamics and upwelling processes.

Speakers: Dr Johannes Karstensen (GEOMAR), Dr Joke Lübbecke (GEOMAR), Prof. Torsten Kanzow (AWI)
