    Developing an Underwater Network of Ocean Observation Systems with Digital Twin Prototypes - A Field Report from the Baltic Sea (2022)
    IEEE
    Details
    Publication Date: 2024-02-07
    Description: During the research cruise AL547 with RV ALKOR (October 20-30, 2020), a collaborative underwater network of ocean observation systems was deployed in Boknis Eck (SW Baltic Sea, German exclusive economic zone (EEZ)) in the context of the project ARCHES (Autonomous Robotic Networks to Help Modern Societies). This network was realized via a Digital Twin Prototype approach. During that period different scenarios were executed to demonstrate the feasibility of Digital Twins in an extreme environment such as underwater. One of the scenarios showed the collaboration of stage IV Digital Twins with their physical counterparts on the seafloor. This way, we address the research question, whether Digital Twins represent a feasible approach to operate mobile ad hoc networks for ocean and coastal observation.

    Benthic Crawler NOMAD - Increasing Payload by Low-Density Design (2018)
    IEEE
    In:  EPIC32018 OCEANS – MTS/IEEE Kobe, IEEE, pp. 279-285
    Details
    Publication Date: 2021-08-03
    Description: NOMAD is an autonomous benthic crawler carrying scientific instrumentation for scanning a continuous track of the seafloor and performing cyclic oxygen profiles and in-situ measurements of total exchange rates in depth of up to 6000m. It expands the line of preceding crawlers by achieving the highest payload to weight ratio by the application of functionintegrating lightweight design that is instantiated as low-density design in the context of underwater systems.

    ROBEX – Innovative robotic technologies for ocean observations, a deep-sea demonstration mission (2016)
    IEEE
    In:  EPIC3OCEANS 2016 MTS/IEEE Monterey, IEEE, pp. 1-8
    Details
    Publication Date: 2017-02-01
    Description: Innovative robotic technologies are a key to study ocean processes in space and time. The work carried out during the ROBEX-Demonstration Mission on RV Polarstern will test the capability of new and innovative technologies, developed during the HGF Alliance ROBEX, in deep-sea environments. Investigations will include Arctic benthic and pelagic ecosystems strongly influenced by climate change, such as marine arctic sediments hosting gas hydrates and arctic deep-sea benthic communities. Different robotic platforms, including 3 types of crawler, glider, AUV, UAVs and senor systems (like Lab-on-a- Chip and multi-O2-profiler) are described and mission scenarios presented. The use of these new underwater technologies will improve our capabilities to improve our knowledge on the effects of climate change on the Arctic ecosystem and ocean observation.

    TRAMPER - An autonomous crawler for long-term benthic oxygen flux studies in remote deep sea ecosystems (2016)
    IEEE
    In:  EPIC3OCEANS 2016 MTS/IEEE Monterey, IEEE, pp. 1-6
    Details
    Publication Date: 2017-02-01
    Description: TRAMPER is an autonomous benthic crawler equipped with oxygen sensors to perform long-term flux time series measurements at abyssal depth. The crawler is developed within the HGF-Alliance ROBEX. TRAMPER has five main subsystems: the titanium frame with the flotation, the caterpillar drive system, recovery and communication systems, energy and electronics and a multi-optode profiler as the scientific payload. A lithium-ion battery pack provides the energy to run an oxygen profiling system performing consecutive measurements (〉52 cycles) along its transecting moving on the seafloor. This new generation of optode-based oxygen monitoring system allows using 18 oxygen optodes and is able to perform in situ calibrations. A video-guided launching system is used to deploy the crawler at the seafloor. At the seafloor the pre-programmed mission scenario is performed consisting of consecutive sleeping, moving and measurement cycles. The aim is to cover a seasonal cycle of settling organic matter on the seafloor and to resolve the impact on the benthic community respiration activity.
