Session 1: Sentinels of the Sea: Ecology and Conservation of Marine Top Predators

Session chair: Dominik A. Nachtsheim and Brigitte C. Heylen

Marine top predators, such as cetaceans, seals, seabirds and elasmobranchs, represent an essential part of marine ecosystems. They are generally regarded as sentinels of the sea since their presence can, for instance, reflect high biological productivity and stabilize marine food webs. Besides their ecological role, these top predators are also socio-economically important. Many populations, however, experience dramatic declines attributed to various human induced threats (e.g., pollution, climate change), which highlight the need for effective conservation. This session invites contributions covering a broad range from fundamental ecological studies over modelling approaches to conservation issues.

Session 2: Reading the book of life – -omics as a universal tool across disciplines

Session chair: Jan D. Brüwer and Hagen Buck-Wiese

From the poles to the tropics and from shallow waters to the deep sea: The marine environment is the greatest and most diverse system on the planet. As diverse as the habitats are the disciplines of marine sciences. Understanding the universal molecular languages, has revolutionized the information available to almost all of them. These advances in -omics generate ever more data, demanding data mining and allow specific research questions. We invite researchers across disciplines to submit their research to introduce cutting-edge methodologies, reveal insights achievable thanks to -omics, and inspire approaches across the board.

Session 3: Physical processes in the tropical and subtropical oceans: Variability, impacts, and connections to other components of the climate system

Session chair: Tina Dippe and Martin Krebs

The tropical-subtropical oceans are key regions of the global climate system and affect livelihoods across the globe. We invite research that is concerned with understanding and predicting variability, or dealing with its regional and global impacts. Possible contributions include, but are not limited to, observational and modeling studies about the El Niño-Southern Oscillation, the Indian Ocean dipole, tropical Atlantic variability, equatorial and eastern boundary upwelling systems, tropical monsoons, and tropical cyclones. While we wish to focus the session on physical processes, we strongly encourage researchers from other disciplines to submit studies that link biological, chemical, and other research to the tropical oceans.

Session 4: Cephalopods: Life histories of evolution and adaptations

Session chair: Fedor Lishchenko and Richard Schwarz

More than 400 million years ago the first cephalopods started inhabiting the World Oceans. Today their modern representatives spread around the world. Impetuous squids, intelligent octopuses and other cephalopods can be found everywhere from epipelagic layer to abyssal depths, from the coast to the open seas in almost every latitude from the tropics to Polar Regions. Living in such different habitats and ecological niches demanded from cephalopods development of several morphological, biological and behavioral adaptations. We warmly welcome biologists, ecologists, paleontologists, neurobiologists and specialists in fisheries management to present results of their studies at our session and to discuss these adaptations.

Session 5: Ecosystems dynamics in a changing world: regime shifts and resilience in marine communities

Session chair: Camilla Sguotti and Xochitl Cormon

Over the last decades many marine ecosystems and fish populations all over the world have undergone drastic changes, termed regime shifts, because of the additive effects of anthropogenic and natural stressors. We invite you to present: i) Studies related to marine ecosystems structure and population dynamics (i.e. food-webs, spatial distribution, regulating processes, top-down and/or bottom-up), as well as potential drivers of regime shifts. ii) Examples of shifts and resilience of ecosystems and studies comparing regimes across different scales (temporal or spatial). iii) Studies investigating impacts of regime shifts on ecosystem services and potential implications for management and stakeholders.

Session 6: The interplay between marine biodiversity and ecosystems functioning: patterns and mechanisms in a changing world

Session chair: Francisco R. Barboza, Maysa Ito and Markus Franz

Existing knowledge on the role of biodiversity in determining ecosystems’ characteristics and their capacity to cope with human impacts has been mainly generated by terrestrial ecologists, leaving the information about marine environments restricted to a small number of publications. Thus, a bigger number of observational and experimental works are required, in an effort to generate valuable data that allow effective conservation strategies in the sea. The scientific session welcomes contributions on the interplay between biodiversity and structure-functioning in marine ecosystems, over all spatial and temporal scales. Theoretical and applied researchers, with a purely ecological or interdisciplinary background are welcome to share their work and ideas.

Session 7: Ocean optics and ocean color remote sensing

Session chair: Veloisa Mascarenhas, Yangyang Liu and Therese Keck

Ocean color remote sensing (OCRS) supports many research fields such as ocean bio-geo-chemistry, physical oceanography, ocean-system modeling and other climate change studies with its unique capability of providing synoptic view of the aquatic ecosystem. This session invites in-situ and satellite studies of marine bio-optics and OCRS such as hyperspectral radiometric observations, light interactions with optically active constituents (phytoplankton, colored dissolved organic matter, total suspended matter), inherent and apparent optical properties, algorithm development & validation, atmospheric correction algorithms, time series analysis, products and applications using multiple platforms and coupled models.

Session 8: Polar ecosystems in the age of climate change

Session chair: Maciej Mańko and Katarzyna Walczyńska

Polar regions are particularly susceptible to climate change. Even smallest modification of any of the physical characteristics of water will cause cascade of dramatic effects influencing all levels of biological organization. Already harsh environment will become even more challenging, thus affecting species reproduction, dispersal, and various other aspects of organismal biology and ecology. Complexity of polar ecosystems, together with logistical constraint in conducting research there are hampering proper recognition of their current state, and as such further predictions of possible impact of climate changes. This session encourages all polar-related contributions investigating these vulnerable ecosystems in the age of changing climate.

Session 9: The physics of the Arctic and Subarctic oceans in a changing climate

Session chair: Camila Campos and Myriel Horn

The Arctic climate system has been drastically impacted by the changing global climate. While summer sea ice reduced dramatically/significantly, and the atmospheric warming is amplified over the Arctic, changes in the ocean are less obvious due to its higher inertia. However, Arctic and Subarctic Oceans play a crucial role in modulating mid-latitude and polar climate. Thus investigating the pathways and timescales of oceanic and atmospheric dynamics is crucial to understand major aspects of current climate change. We invite presentations advancing our understanding of the relevance of Arctic and Subarctic Oceans.

Session 10: Phytoplankton in a changing environment – adaptation mechanisms and ecological surveys

Session chair: Jana Geuer and Laura Käse

The enormous importance of oceanic primary production is not only limited to the marine environment but has an equally great impact on the global atmosphere. Our changing climate affects the composition of phytoplankton species composition and requires the organisms to adapt to this changing environment, influencing micronutrient bioavailability and other biogeochemical parameters. Studies to monitor phytoplankton species composition are as important as are molecular and genetic approaches on understanding adaptation mechanisms of phytoplankton in regard to changing oceanic conditions. Studies dealing with different approaches on monitoring changes in phytoplankton, their impact on the microbial loop and adapting mechanisms are welcome.

Session 11: How do they do it? – Understanding the success of marine invasive species

Session chair: Jonas Geburzi and Morgan L. McCarthy

From the depths of the oceans to the shallow estuaries and wetlands of our coasts, organisms of the marine environment are teeming with unique adaptations to cope with a multitude of varying environmental conditions. With millions of years and a vast volume of water to call their home, they have become quite adept at developing specialized and unique techniques for survival and – given increasing human medi­ated transport – biological invasions. The theme for this session calls for abstracts on marine invasions and how their life history strategies and specialized adaptations have made certain organisms particularly successful at invading new habitats.

Session 12: Coastal ecosystem restoration – innovations for a better tomorrow

Session chair: Jana Carus and Matthias Goerres

Coastal ecosystems provide a variety of services. Due to increasing anthropogenic pressures, such as large-scale shipping, overfishing and eutrophication, the degradation and loss of suitable habitat in the past decades has led to numerous – yet more failed than successful – efforts of ecosystem restoration. This evokes a necessity for innovative approaches and alternative solutions. This session will comprise of the assessment of coastal ecosystem integrity, the identification of suitable restoration sites as well as the design of restoration measures and products. Studies covering these issues in salt marshes, seagrass/macrophyte beds, mussel banks, mangroves or coral reefs are very welcome.

Session 13: Microplastics in aquatic habitats – environmental concentrations and consequences

Session chair: Thea Hamm, Claudia Lorenz and Sarah Piehl

Microplastics (< 5 mm) have recently become a topic of great societal concern and a widely studied field. However, there are still many knowledge gaps concerning abundances, sources, sinks and transportation pathways, as well as their impact on biota. Reasons for this are the challenging analytical methods and demanding experimental set-ups for organism studies as well as the lack of standardized operational procedures. To close these gaps and generate comparable data in the future, we invite young scientists to present innovative methodologies along with studies assessing the concentration of microplastics in the environment or their impact on aquatic life.

Session 14: Tropical aquatic ecosystems across time, space and disciplines

Session chair: Mona Andskog, Hannah Earp, Natalie Prinz and Maha Cziesielski

Coral reefs, mangroves and seagrasses are among the most diverse, productive and complex ecosystems on the planet. They are also among the most vulnerable and are declining at unprecedented rates. The high complexity of these environments means they are difficult to study from a single perspective or on single scales, thus making it of critical importance to study them across time, space, and scientific disciplines. Only then will we fully understand their functioning and how to successfully manage and preserve them for future generations. This session will explore the lessons being learned through current interdisciplinary and comparative tropical marine research.

Session 15: Open Session

Session chair: Simon Jungblut

Marine sciences are a vast and divers field of research and barely any conference is able to represent all topics with a separate session. The Open Session will summarize contributions of young marine scientists from all research fields which do not feel to fit into one of the other sessions.
