After two years of online conferences, this year we could finally meet in person again for ICYMARE 2022 BREMERHAVEN. The conference took place from 13th to 16th of September in Bremerhaven in the North of Germany, and was hosted by the University of Applied Science Bremerhaven. We were happy to welcome 333 participants from 37 countries and representation from all continents at the conference. Participants were mainly master students (66%), followed by bachelor (22%) and PhD candidates (12%). In 30 sessions, a total of 114 oral and 20 poster presentations were given, and participants could choose from a variety of workshops.

The Icebreaker event in the main hall of the Alfred-Wegener Institute, Helmholtz Centre for Polar and Marine Research on Tuesday evening presented the kick-off for the conference. More than 80 participants joined for drinks and snacks. A highlight was the game ‘bingo’, where participants got the chance to get to know each other in a playful way.

On the following days, the University of Applied Science Bremerhaven opened the doors for the participants for three days full of presentations and networking activities. The opening words from the university and our local sponsors ‘Freundeskreis Bremerhaven’ gave the start to the conference and warmly welcomed the early-career-scientists (ECRs) in Bremerhaven.


Scientific Sessions

The following sessions and presentations at ICYMARE 2022 BREMERHAVEN centred around six main streams: management and conservation; new age of monitoring; insights into a changing ocean; ecosystem dynamics; an ocean full of numbers; and innovative technologies. For the first time at ICYMARE, the stream management and conservation included several interdisciplinary sessions at the interface of social/political science and marine conservation. Sessions in this stream included emergent topics, such as the importance of weaving Indigenous knowledge into research, social-ecological systems research and transforming governance for sustainable futures.

More emerging and highly relevant topics were also addressed in other streams. For example, within the stream new age of monitoring, novel monitoring techniques and progressive methodologies for assessing biodiversity and marine resources were presented. Presentations tackled this topic from the species to the population level and through time, including alternative methods for monitoring marine wildlife and resources, bioarchaeology of marine systems, molecular tools, and aquatic animal telemetry.

Other streams included latest research on the impact of changing conditions on marine life, providing insights on climate change, plastic pollution and biodiversity loss in the marine realm (insights into a changing ocean), and ecosystem dynamics from microbial communities, over marine forests to coral reef ecosystems. Finally, presentations in the streams an ocean full of numbers and innovative technologies presented a more mathematical and physical approach to the marine sciences, including sea ice dynamics, impacts of whirls and waves, and new technologies for and from ocean science, such as marine biotechnology and marine engineering. Presentations that did not fit into any of the other sessions were presented in the open session.


Art Projects

Besides the scientific program, participants joined various networking events and contributed to amazing art projects. This year we celebrated the first ICYMARE Art Exhibition! In the 6 weeks leading up to the conference, 10 ICYMARE participants created a series of 30 Artworks around the theme “Exploring Boundaries and the Bottom”. It was based on this video featuring one of the first bathymetric maps of the Ocean created by Marie Tharp and Bruce Heezen and an excerpt from the book “Undrowned – Black feminist lessons from marine mammals” by Alexis Pauline Gumbs. The art project used the “Exquisite Corpse Method”, where participants create a series of artworks centred around the main seed, but based on exchanging their artworks with each other and building on what other people have created. If you want to learn more about the process, you can check out the poster we created for the exhibition here.

Soon, we will also share a video showing the exhibition and creations on our website! But in short – there was a huge variety of artworks and mediums ranging from photography, comics, art installations, collages, writings, videography, to a poetry sculpture. Apart from this exhibition, there was also a mini-story sculpture installation in the Lounge room. Here, everyone was invited to tie an object or little note, representing their own ocean stories and connection to a big braided rope. Overall, there seemed to be a big interest in all of our artsy activities and we are planning to expand them for ICYMARE 2023 OLDENBURG!


Keynote presentations and plenary discussion

After the opening on day one, participants engaged in the first keynote presentation by Julia Olsen from the Nordland Research Institute and a following plenary discussion. In her keynote presentation, Julia emphasised the deep-rooted relation between society and nature by using the Arctic Ocean as an example. Julia also highlighted the need for inter- and transdisciplinary approaches to translate scientific knowledge into action within the UN Ocean Decade. Using an interactive tool, participants could reveal their motivation to contribute to marine research and the meaning of the UN Ocean Decade (results are shown in the word clouds below). Participants could also show their agreement to three statements around the need for communicating scientific findings to society and decision-makers, the usefulness of social media, and the question, if early-career researchers (ECR) are in a position to make the change they want to see.

One highlight from the discussions was that even though most of the participants agreed that they do not see the necessary change they would like to see, we – as ECRs – are part of the change. We are the next generation of researchers, who will be in charge in the next decades and will shape the emerging research agendas! Participants also agreed that social media is a useful tool to share scientific results, but it is not the task of ECRs to make sure that their results reach decision-makers. More importantly, ECRs should concentrate on what they are best at – science – and leave the communication to people who are more trained in that field. The UN Ocean Decade provides a useful frame for societal relevant research and means many different things to the ECRs – but mainly creating an awareness in public for achieving sustainable development for the oceans (second word cloud).

In the second Keynote presentation Caroline Ngorobi further explored the connection between science and society by highlighting the role that art can play in this process to connect, share and mobilise. Caroline started her presentation with her own journey and experience of being a theatre producer in Kenya and moving into working in collaboration with scientists to inspire behaviour change and social activism. She shared her experience of managing to connect and create impactful theatre pieces together with scientists by developing a shared language and understanding. Through a series of artworks created as part of the Bahari Huru Ocean Art festival and residency hosted at Jukwaa Arts Productions, she invited the audience to take some quiet moments to reflect and feel the impacts of the artworks in their own bodies.

In the second part of her talk, Caroline shared best practices about how to collaborate in the ArtScience space. At the end of her talk, Caroline invited the audience to put into practice what they just heard. She engaged the audience to develop a news story about the Ocean from the perspective of a marine organism. Challenging everyone to put on a different hat to find a funny, thoughtful or unexpected framing of common marine issues brought out a lot of laughter and new insights on the latest news about the “octopus housing crisis” and “jellyfish invasion”. In the Q&A part of the session, many participants shared their inspiration and hopes from Caroline’s talk. One key takeaway was the idea that while the Ocean as well as ECRs face many challenges, we do not have to overcome them alone. As a community and ICYMARE family, we can support each other. From a disciplinary perspective, marine researchers do not have to do it all alone – we can connect with others and draw on other disciplinary tools, ways of thinking and perspectives.

1 Management and Conservation

Implementation of scientific results into conservation approaches; Interworking of scientist, stakeholders and policymakers

Hosted by Jorge Moreno

The oceans are a vast resource, providing food, raw materials (extractive activities), as well as supporting tourism activities all over the world (non-extractive). As such, it is fundamental to protect and conserve this system and its inhabitants. Adequate management and enforcement are necessary for conservation, but they can only be accomplished through science. Therefore, it is our best tool for marine conservation. If your research is contributing to the conservation of the marine environment, we invite you to submit an abstract for this section and share your experience with the rest of early career ocean professionals and conservationists!


Hosted by Solomon Sebuliba & Sonia Akrour

Effective conservation and management of biodiversity depends on defining, measuring, and representing the different levels of biodiversity (e.g., species, genes, and ecosystems) in time and space when formulating policies. Therefore, all research processes (investigations, data collection, dissemination of results) are critical. This session is for researchers who have studied a particular area or ecosystem and are interested in disseminating their results or finding out how their data can be used to promote management policy. It may also be of use to individuals who wish to replicate conservation actions that have been conducted in other countries/contexts.


Hosted by Emily Chen

There is a global need to address the social impacts of marine conservation, especially since the communities most vulnerable to climate change impacts are rarely given an equal voice. We welcome abstracts of studies conducted on the inclusion of any social science field in marine research, from traditional knowledge to socioecological consequences to linguistic barriers in policy decisions. Submissions should focus on interdisciplinarity and best practices to approach and standardize social science methods into marine research. We hope to receive submissions on a range of original topics and invite you to take part in this important conversation!


Hosted by Natalie Prinz & Megan Ranapia

Managing and restoring our complex marine ecosystems from past and present anthropogenic activities requires a comprehensive understanding of social ecological interactions. Globally, there is increasing appreciation that indigenous and traditional ecological knowledge (TEK) can provide valuable lessons towards conservation and contribute significantly to ecosystem management. Despite this proposition, indigenous knowledge is severely underutilized, partly because there is a large void as to how practitioners can synthesize different knowledge systems. Our interest lies in research by ECRs who collaborate with local communities, how to overcome obstacles and seize opportunities. We invite presenters from multiple disciplines to contribute to our online session.

Marine ecosystems are increasingly threatened by a multitude of anthropogenic pressures. Identifying systems at risk and vulnerable components is therefore highly important for ensuring the sustainability of our oceans. However, this can be challenging as pressures often interact with each other, leading to cumulative impacts and feedback loops. This warrants not only for single species assessments evaluating multiple pressures but also holistic approaches focusing on entire ecosystems. We therefore invite everyone working on risk and vulnerability evaluations ranging from single species to ecosystems, including status and distribution assessments and services they provide, especially under the influence of combined impacts

As the Arctic ice is melting, coastal communities of the North face some of the most uncertain futures, battling increasing maritime activities, economies dependent on limited resources, depopulation, non-representation and consequences of rapid climate. To adapt to such conditions, transformative approaches to governance need to be applied. This session will explore governance issues and transformative approaches to enable shared understanding across the Arctic and beyond. We invite you to submit your abstract on research relating to governance issues and solutions in coastal communities in the North. Submissions are accepted from all scientific fields with special focus on interdisciplinary work.

The proper control of the exploited marine resources is essential for the adequate management either from an environmental or human health point of view. Different approaches can be applied to reach an appropriate transparency regarding the product that is being consumed, such as the identity of the species, its origin or the possible contaminant content. For this, different techniques might be used: genetic tools, pollutants analysis, etc. Avoiding commercial fraud and raising awareness about possible health hazards and the troubling management of some species (especially those of conservation interest) are factors that may be of special importance in the future.

In marine aquaculture systems organisms throughout the natural food chain are cultured. However, contrary to the general assumption, marine aquaculture production is dominated by extractive species, mostly seaweeds, but also filter feeders and deposit feeders like bivalves or echinoderms. In order to push forward sustainable aquaculture, integrated systems where organisms of different trophic-levels are complementary cultured, gain in interest. We are inviting researchers from both, natural and social sciences to share their story on low-trophic aquaculture organisms, techniques and challenges.

2 New Age of Monitoring

Emerging monitoring techniques and progressive methodologies to assess biodiversity and marine resources, from species to population level, and even through time

Hosted by Constanze Hammerl

Monitoring is a key aspect of managing marine environments. It has enabled the development of a science-based understanding of marine ecosystems and human impacts affecting it. In the context of increasing construction at sea, the establishment of no-take zones and the associated inappropriateness of many traditional methods, as well as the general societal quest for more efficient and sustainable technologies, the following question arises: How can future monitoring be designed? This session is for anyone investigating more sustainable methods of marine monitoring, whether you are working on new monitoring devices, sampling strategies and concepts or more efficient data processing.

Hosted by Magie Aiken

Bioarchaeological investigation of marine species adds to our understanding of human exploitation and its impact on marine ecosystems. This directly ties into modern ecological studies by contextualizing current research within a long-term approach not otherwise feasible. We invite researchers who use bioarchaeological methods to study any aspect of marine systems to share their research. This session invites contributions from a broad range of bioarchaeological methods, research questions, time periods, and target species to share their perspective on the past, present, and future of marine systems.

Marine samples archiving (biobanking) is a growing field. Repositories offer hedges against rapid biodiversity declines and sources of reference samples for research. They also pose new and accelerating problems to be explored. Are you interested in cryopreservation or -omics databases? Do you work with bioactives and biomaterials? Do you study equitable access or organize citizen/community science efforts? Join our interdisciplinary conversation on coalition building, citizen science, information accessibility, and technical methodologies, as applied to wide-scale distributed biobanking efforts. This session aims to bring together participants with diverse backgrounds and interests, to share complementary views on the future of archival collections.


Hosted by Eileen Heße & Kim Ludwig

Marking the 30th anniversary of the Convention on Biological Diversity, this session will be dedicated to modern approaches to studying marine biodiversity. In a conceptual context, functional biodiversity has gained much attention over recent years, considering species characteristics (“traits”) rather than -identities and thereby allowing for new insights into the drivers of biodiversity. Technologically, molecular methods such as metabarcoding have emerged and provide new possibilities for identifying cryptic species. In this session, we invite speakers working on marine biodiversity questions to share their experiences with, and insights gained from, using modern techniques of biodiversity research in marine ecosystems.


The use of Environmental DNA (eDNA) is increasingly applied within molecular biology for the detection of species based on DNA-traces left behind in the environment. In this session, we want to explore the technical advancements made, and hear all about the hands-on applications of the concept.

Subsession 1: Aquatic Biodiversity and Stock Assessment: Genetics and Computational Methods

Hosted by Yassine Kasmi

Technological progress in high-throughput sequencing and bioinformatics has raised questions about the necessity of continuing with invasive methods for biodiversity and single species stock assessments in aquatic habitats. This subchapter aims to highlight applied molecular and computational biology methods as well as bio-modelling to solve these questions.

Subsession 2: eDNA approaches to ecological questions

Hosted by Paulina Urban, Lara Jansen & Anna Joelle Greife

The concept of eDNA can be applied to activities within ecosystem surveillance, monitoring or conservation. This subchapter focuses on WHERE, WHEN and WHY eDNA is used, including, but not limited to fields like fisheries management, population dynamics, modelling, invasive species detection, studies on aDNA, nsDNA or iDNA and more!

Hosted by Jena Edwards & Eleanor Greenway

In aquatic ecosystems, observations of individual animal behaviours are limited by factors such as broad-scale habitat connectivity, study site inaccessibility, and physical properties including extremes in ambient pressure, temperature, and light levels. By employing biotelemetry, numerous approaches are now available for capturing individual movement behaviours remotely and for extended periods, providing insight into broader ecological consequences related to species distributions, migratory patterns, and habitat use. This session aims to explore all aspects of aquatic animal movement ranging from long-distance movements to diel vertical migrations and fine-scale behaviours to better understand the links between individual behaviours, population dynamics, and community-level processes.

3 Insights into a changing ocean

Changing conditions and their effects across on biological communities

Hosted by Christian Simeoni & Fabiola Espinoza

Marine coastal ecosystems play a central role in maintaining healthy marine regions. However, cumulative impacts arising from multiple pressures are threatening their ecological conditions and the services they provide, decreasing their ability to response to impacts such as climate change. Therefore, unravelling the climate change-biodiversity-ecosystem services nexus, paying attention to both environmental and socio-economic dimensions is a priority for researchers. This session invites presentations on methods and applications from various field of studies, exploring how integrated frameworks and models can expand our current knowledge on this nexus, and, guide ecosystem-based practices to both address and adapt to climate change.


Hosted by Selma Mezger & Johanna Berlinghof

(Sub-)tropical coastal waters are among the most diverse and productive ecosystems, providing various ecosystem services and sustaining human well-being. However, coastal ecosystems, like coral reefs, seagrass meadows, and mangrove forests are impacted by local and global environmental stressors (e.g., climate change, eutrophication, overfishing). Understanding their ecological and biogeochemical responses to environmental changes is key and can ultimately help to inform managers, policymakers, and stakeholders as a step towards better conservation and restoration. We welcome presentations on all kinds of (sub-) tropical coastal ecosystems to discuss and learn about the impacts of changing environments.


Hosted by Magda Cardozo & Anabel von Jackowski

Global climate change, increasing temperatures and pollution affect the health of the oceans with distinct effects on marine systems on multiple scales. Tracking the ecological and physicochemical impacts of environmental change might be monitored better if we coordinate global observing systems more cohesively. This includes better coordination, standard practices and harmonised outputs across observatories. Long-term studies are key to detect comprehensive indicators and generate valuable assessments. In this session we aim to bring together transdisciplinary research working on bioindicators of the Global Ocean’s health and on coordinated efforts. We invite researchers from multiple disciplines and all career stages, but early career researchers are especially encouraged.

Marine primary producers play a fundamental role within oceanic ecosystems. Not only do they form the base of marine energy flux and provide half the atmosphere’s oxygen, they furthermore contribute significantly to major biogeochemical cycles and thus carbon export. Due to global change, they are partially facing drastic alterations of their habitat in terms of temperature, nutrient availability, pH and salinity. Especially in extreme environments such as polar regions, the tropics, intertidal systems, and estuaries, primary producers could be pushed beyond their limits. We encourage all scientists working on marine primary producers – from algae to seagrass – to join our session.

Hosted by Annabell Klinke & Svea Vollstedt

Species are on the move because of human-mediated climate change, shifting their distribution (generally) poleward at regional to global scales. This, in turn, alters ecosystem structures, functions, and services with consequences for human well-being. Species redistribution dramatically affects fisheries and socioecological systems worldwide, yet leaving some more vulnerable than others (i.e., Small Island Developing States). Therefore, we invite presenters from natural and social sciences to advance our knowledge on the challenges generated by climate-driven species redistribution. We welcome abstract submissions from studies filling knowledge gaps related to climate change effects on marine species, communities, ecosystems, or socioecological systems.

Hosted by Erik Sulanke

Climate change is undoubtedly the greatest challenge humanity is facing in modern times. It will alter the world’s oceans’ chemistry, physics, and biology, which will have cascading effects on all marine ecosystems. Millions of humans worldwide depend on the services those ecosystems provide, be it in the form of food, oxygen, protection, or employment. We call for dedicated young marine scientists who use state-of-the-art approaches to explore, predict, and model the effects climate change will or might have on the marine ecosystem with special respect to human use forms and socio-ecological interactions.

Recently, novel microplastic sources such as ship paint contamination have been identified. These polymer-based paints have been recorded in the relatively pristine environment of Antarctica, from the surface waters of the Weddell Sea to the depths of the South Sandwich Trench, and in rocky intertidal gastropods from the North Sea, Mediterranean and Atlantic Ocean. Furthermore, novel plastic pollution types (‘plasticrusts’, ‘pyroplastics’ and ‘plastiglomerates’) which were recently identified may become part of the future sedimentary record. We welcome you to submit an abstract on novel plastic sources and types and join us at ICYMARE Bremerhaven 2022.

4 Ecosystem dynamics

Ecological and physiological transformation of ecosystems and organismal interactions

Hosted by Kara Engelhardt & Jana Vetter

Oceans harbour a variety of ecosystems inhabited by a wide range of organisms. From competition, over predator-prey to symbiotic relationships, they interact and communicate in multiple ways, forming a complex interaction network. Interactions can occur via direct contact or mediated by the surrounding water. Understanding these relationships and their underlying processes is crucial for conservation efforts. This session wants to bring together lines of research that investigate relationships of organisms on the holobiont, species, or ecosystem level. We look forward to all research that deals with interactions between marine organisms and studies which investigate changes in interactions through anthropogenic stressors.


Hosted by Ronen Liberman & Jessica Bellworthy

Coral reefs are the most biodiverse and economically important marine ecosystems worldwide. However, due to anthropogenic pressures, present day reefs are undergoing immense changes in species’ abundance and community composition, which are likely to influence future coral generations, the myriad of organisms they support, and the services these ecosystems provide. This session aims to bring together researchers working to elucidate the past, present, and future dynamics and ecology of coral reef regions around the world. We are seeking to incorporate a wide range of techniques at every organizational level from molecular to ecosystem functioning.


Hosted by Celina Burkholz & Philipp-Konrad Schaetzle

Marine macrophytes are hosts to individual microbial communities on their leaves, roots, and other compartments of the plant. The relationship between host and microbes is complex, and the host‘s fitness and performance can either benefit or suffer from this relationship. Additionally, the microbial community can greatly vary with changing environmental conditions and other surrounding factors, which in turn has varying impacts on the host. This session invites scientists to present their findings on the relationship between marine macrophytes and microbial communities and the resulting effects on the host organism and microbiome.

“It is not the strongest of the species that survives, not the most intelligent that survive. It is the one that is the most adaptable to change.” (Charles Darwin). Today, the climate is changing fast and all organisms have to adapt to increasing temperature, acidic enriched oceans and lower oxygen level otherwise they will get extinct. What are the strategies and mechanisms of marine animals to cope with climate change? The session will examine this question from the perspective of ecological and physiological mechanisms of marine organisms facing elevated temperature, hypercapnia and/or hypoxia.

Marine forests characterized by large brown macroalgae, also known as kelp forests, are known for their role as ecosystem engineers. They provide habitat and shelter, food, and protect the coastlines by slowing down waves and currents. Furthermore, kelp forest ecosystems are socio-economically important as they provide jobs and income in many parts of the world. In recent years, kelps have gained more attention as a source of blue carbon. This session welcomes all studies related to kelps and other macroalgae – be it their ecology, physiology, the ecosystem services they provide, or their utilization and restoration efforts

Hosted by Fedor Lishchenko & Andrew Balashov

Tropical coastal ecosystems are an iconic example of rich and complex but vulnerable marine habitat. Complexity and delicacy of linkages between coral reefs, seagrass beds and mangrove forests left the whole system exposed to modern threats, such as global warming, introduction of invasive species, overexploitation and pollution. There is an urgent need to develop old and implement new approaches to research of tropical coastal ecosystems, to support its conservation and rational exploitation. Do You have suggestions on how to fulfil this goal? Then join us and share your vision!

5 An ocean full of numbers

Maths and Physics in ocean science to observe and understand complex environmental systems and ecological datasets

Hosted by Ellen Oldenburg

Communities of various trophic levels are central elements of marine ecosystems. Strongly influenced by the environment, they exhibit pronounced regional and temporal variability. A profound understanding of their dynamics is essential to predict the fate of future marine habitats and to provide a wider range of future scenarios for marine ecosystem functionality and services. Current descriptive analyses alone are insufficient to understand microbiome composition and interactions. For this session, we invite contributions employing statistical, computational, and mathematical approaches to analyse complex dynamic environmental data, aiming at increasing our understanding of complex marine ecosystems and predicting the expected effects of, e.g. global climate change.


Hosted by Hannah Niehaus & Linda Thielke

Sea ice is a very fascinating, but also complex component of the polar climate system. There are numerous linkages between the physical processes of the ice and the other components of the polar climate system. Ice dynamics as well as heat exchange and light transmittance influence the atmosphere, ocean and ecology depending on the season. With a combination of observations, satellite measurements and modelling we can gain a better understanding of the processes related to sea ice in polar regions. This is important especially in a warming climate as the polar climate also influences other parts of the Earth.

People of all ages and cultures dream about living within sight of the ocean. Globally, between 50-60% of the world’s population live at the coastlines, and relevant infrastructure is positioned there. However, in the last century, the rising sea level led to unprecedented changes. With more frequent extreme weather events such as storm surges, societies at the coast are one of the most vulnerable groups in a changing climate. Is it still possible to stop sea-level rise? To answer that, we invite you to participate in our session and investigate with us the mechanisms of sea-level rise.

Hosted by Nicolas Dettling & Simon Felix Reifenberg

Eddies and internal waves are prominent dynamic features transferring energy from the large-scale ocean circulation to small scales, where they can drive intense mixing. They thereby shape the local dynamics and stratification, as well as the transport of passive tracers like nutrients or pollutants. Many questions still remain about the generation, distribution and impact of ocean mixing, requiring innovative approaches from many marine science disciplines. We therefore invite contributions from all researchers interested in describing, observing or modelling small-scale oceanic motions that lead to ocean mixing, and its impacts

Hosted by Finn Heukamp & Zerlina Hofmann

In our changing climate, polar regions are particularly affected. Sea ice cover in the Arctic is rapidly declining, oceanic heat transport is changing and the Arctic Ocean is becoming subject to novel environmental conditions. A thorough understanding of the large-scale circulation, associated (sub)mesoscale processes such as eddies, fronts or filaments in the ocean, and their impact on heat transport, ice melt, and biology are essential for future projections of Arctic climate. In this session we invite contributions from observational and model studies, studying the processes, mechanisms, and changes of the Arctic Ocean.

6 Innovative Technologies

New technologies for and from ocean science

Hosted by Inês Moutinho Cabral & Cátia Gonçalves

The oceans hold a tremendous biodiversity, withstanding an immense span of natural products that may be translated into multiple biotechnological applications: therapeutical drugs, cosmetics, pesticides, fuels, biomaterials, feed and supplements. They can constitute a safer, cost-effective and more eco-friendly solution than the complex process of producing synthetic compounds. Also, it contributes to shift between deleterious exploitations of the seas towards “green-industry”. Recently, this area has been attracting growing enthusiasm among young marine researchers. Therefore, we kindly encourage ICYMARE participants to contribute and share their research on Marine Biotechnology as we expect to discuss novel approaches, methodology and prospective biotechnological applications.

Autonomous and remotely operated vehicles are becoming more influential as research platforms for ocean sciences, the industry, and other applications. This trend emerging from better lasting cells for electrical energy, or the new development of microelectronics and sensors provides an attractive field for young engineers. Apart from a large variety of AUVs and ROVs available on the marked or self-made, there are multiple different approaches to collecting data underwater. In this session, we would also love to learn about your ideas on sensors and systems one can use on such a platform. Professionals, researchers and graduates from different backgrounds get the chance to present their own ideas and involve others in a constructive discussion.
