Research Interests

Numeric modeling - Cold-water corals - Robotic monitoring technologies

Numeric modeling

My research focuses on the use of numerical climate and biogeochemical models (full coupled GCMs, earth system models of intermediate complexity, and biogeochemical box models) in global and regional climate research. Covering geological, present day, and future time scales I investigate the role of global biogeochemical cycling of C, P, O2, ... and the terrestrial hydrological cycle on e.g. marine nutrient inventories, ventilation of the water column. Most of my research is dedicated to times of global warmth, e. g. greenhouse climates where I currently work on the underlying orbital and biogeochemical cycles that lead to the development of Oceanic Anoxic Events (OAEs). The understanding of processes ‘unique’ to greenhouse climates is of great interest for insights into past and future climate change. Currently, we’re coupling and running biogeochemical box models to a GCM to investigate marine oxygen concentrations during OAEs in the Cretaceous.
Another focal point of my research is the influence of orbital cycles, so-called Milankovitch cycles on Earth’s climate and sedimentation patterns during the geological past.

Cold-water corals

A second topic of my current research is the growth and distribution of cold-water corals (e.g. Lophelia pertusa) and their relation to the hydrographic regime of the ambient water masses. Therefore, we use state-of-the-art marine stand-alone observatories to conduct long-term measurements of various physical and biogeochemical parameters in bottom waters and throughout the water column in multiple ocean basins

Projects

iFOODis - Improving the sustainability of food cycles through intelligent (robotic) systems (2023-2027)

iFOODis contributes to the improvement of sustainable food production by establishing an intelligent robotic monitoring network for the continuous assessment of ecosystem health on land and surface waters in relation to agricultural activities. The synoptic observation of food crop state, agricultural activity and environmental parameters in the atmosphere, on land and in surface waters enables the development of management options and recommendations for authorities and policy makers based on a scientifically sound data base. To this end, iFOODis will encompass the development and application of satellite remote sensing as well as aerial, ground-based, and underwater robotic and sensor networks.
This includes methods for data acquisition and interpretation, robotic semantic navigation and exploration, autonomous sampling and sensor deployment, robust wireless communication, ranging, and timing, as well as data management aiming to collect relevant data in an efficient manner and use it to improve the situational awareness.
The iFOODis network is intended for three fields of application and is aligned with the "Sustainability Development Goals (SDGs)" of the "United Nations Development Program (UNDP)" as well as the guidelines of the international bodies for marine protection. The first application is envisaged for the
Schlei-region (Baltic Sea, Germany), belonging to one of the areas most severely impacted by agriculture. We aim for a high and cost-efficient transferability of the network to other regions. Recommendations will address, e.g., measures of how to improve ecosystem health in land and water, resource efficiency, strategies for land-use and fisheries. A further focus is on the remote-operated transport of food and material in flooded, harsh, and difficult-to-reach regions, where conditions could be hazardous to human operators. Lastly, a third use case of intelligent robots and observational networks is the growing field of commercial agricultural robotics in land management and farming. Specific topics in robotics, data- and agricultural/environmental sciences will be addressed in the iFOODis Graduate School hosted by MUDS and JUB. iFOODis strives for a high transferability of technology and knowledge into the industry in the field of robotics and intelligent data processing as well as for an open-access data policy.

REDRESS – Restoration of deep-sea habitats to rebuild European Seas (2023-2028)

REDRESS aims at providing a key contribution to the European Commission commitment towards nature restoration targets, focusing on the restoration of degraded deep-sea ecosystems. The ambition of REDRESS is to provide solutions to plan the priorities for future restoration actions, extend the deep-sea restoration to new habitat types so far neglected and demonstrate the success of deep-sea habitat restoration. The project will focus on trawled soft bottoms with seapens and bamboo corals, deep-water corals, sponge fields, cold seeps, and other vulnerable marine ecosystems with the highest potential to provide essential ecosystem services to contribute to climate change mitigation. REDRESS will map deep-sea habitat degradation and identify the habitat refugia to prioritize future restoration efforts and contribute to the adaptation to climate change impacts. REDRESS is based on up-to-date knowledge acquired through the H2020 Project MERCES and will provide nature-based solutions to public authorities and operators to up-scale ecosystem restoration in the deep sea. The results of the project (new approaches and technologies, standardized protocols, maps, measures of success) will allow a step change in the marine restoration strategy at EU level for deep-sea ecosystems. The project aims also at providing evidence of the cost effectiveness and the benefits of planning and upscaling restoration by combining active and passive restoration to recover deep-sea ecosystem services and to achieve Good Environmental Status (sensu Marine Strategy Framework Directive) in degraded areas, to substantially increase the benefits on which EU citizens depend.

DIGI4ECO - Digital Twin-sustained 4D ecological monitoring of restoration in fishery depleted areas (2024-2028)

The EU has created 5 missions to provide concrete solutions for the primary challenges that face the EU’s citizens, environment, and climate by 2030. Its ambitious goals are clearly dictated1 in ECs COM (021) 6092. One of these missions is to “Restore our Ocean and Waters by 2030”. This mission will also support the marine and freshwater targets of the European Green Deal, which dictate the protection of 30% of the EU’s marine area and restoration of marine ecosystems. Although several strides have and are being made to offer solutions for the preservation of oceans and seas, there is still a need to develop tools that offer real-time and future predictions of the state of protection or conservation areas. This is the European Digital Twin Ocean (DTO) - a digital representation of the physical ocean, i.e., its area and processes. Although research is being performed toward the realization of the DTO3, there are still many hurdles in populating that virtual infrastructure with data, historically stored or newly acquired. This aspect also includes the harmonization, real-time coverage and data collection of wide areas, advanced prediction capabilities of DTO as well as correlation with human nature generated actions. Moreover, autonomously operating permanent systems for the monitoring of marine activities are multiplying worldwide providing valuable multidisciplinary data as a benefit for scientific, industry and civil stakeholders. This is occurring in a context where permanent marine infrastructures and deployed technologies for ecological monitoring are multiplying into oceans to provide national and international governmental agencies with supervision capability of all industrial activities into continental margins and abyssal basins. That development would be benefited by a concomitant DTO, to manage platforms requirements and protocols for data collection capability, including data organization and modelling with existing official and sleeping repositories.

COWIO - Cold-water Corals in the West Indian Ocean (2024-2026)

Cold-water corals and their associated deep-sea ecosystems are known for the West Indian
Ocean, but are largely unexplored so far. The aims of this project are therefore (I) to conduct
for the first time a systematic inventory of their recent distribution, vitality and biodiversity under
the influence of prevailing environmental conditions (recent situation), (II) to reconstruct their
past evolution steered by climate-induced changes of the paleo-environment (palaeosituation),
in order (III) to finally assess their future development in times of Global Change
based on scenarios of the IPCC. The project will be based on extensive data and sample
material to be obtained during the expedition SO-306 with the RV SONNE (August/September
2024) using state-of-the-art marine technology (e.g. multibeam mapping, remotely operated
vehicle, benthic landers). Main working areas will be volcanic islands and seamounts of the
Comoros and the East-African continental margin off Tanzania and Mozambique. By
combining the expertise of the involved project partners (MARUM, Bremen: Geology/Paleo-
Environment, Senckenberg am Meer, Wilhelmshaven: Geo-Biology, GEOMAR, Kiel: (Paleo-
Oceanography), the proposed project will significantly contribute to our understanding of the
global distribution and importance of cold-water coral ecosystems as well as to the relevant
controlling environmental parameters (today and in the past). The work of GEOMAR will focus
on the invesigation and evaluation of the hydrograhy and the investiagtion of environmental
proxies. This includes the interpretation of the relation between observed cold-water corals
and the ambient physical and chemical boundary conditions. Furthermore, we will assess the
primary control mechanisms of cold-water coral growth and occurrences within the context of
existing data from the Atlantic Ocean and their proxy record in the coral skeleton.
