Climate change and additional anthropogenic pressures induce a wide range of environmental changes in aquatic environments, such as gradual warming, ocean acidification, amplified extreme events, or altered light- and nutrient regimes. However, community and ecosystem level responses to these changes remain unclear as highly controlled laboratory experiments cannot reflect the full complexity of natural systems. Mesocosm experiments are an important tool to fill this knowledge gap by providing a near-natural setting for studying higher system complexity, species interactions, and by offering a wide range of possibilities to manipulate environmental conditions and to test mitigation measures. In this session, we welcome submissions on mesocosm experiments examining single or multiple stressor impacts on different aquatic systems. Studies can focus on the effects on single organisms, populations, or communities (e.g., phytoplankton, zooplankton, benthos, fish), their ecosystem functions, resistance, resilience and recovery as well as eco-evolutionary responses. We aim to include studies across a wide range of aquatic habitats (e.g., fully marine, intertidal, lakes, rivers). Overall, the session aims to provide a comprehensive insight into the possibilities and limitations of mesocosm research for assessing the impacts of global change related stressors on aquatic systems. We hope that this session will fuel the discussion on the status quo in mesocosm research and inspire future collaborations. Join us in exploring the diversity of mesocosm-based experiments used across aquatic systems!

Benthic ecosystems, comprising the diverse communities of organisms inhabiting the ocean floor, play a pivotal role in maintaining ecological balance and sustaining the health of marine environments. Focusing on these vulnerable ecosystems, we examine the multifaceted threats faced by benthic organisms and the subsequent repercussions for ecosystem resilience. Benthic organisms are exposed to a myriad of stressors such as rising sea temperatures, ocean acidification, and alterations in nutrient cycling. Benthic macrofauna plays a key role in organic matter processing and benthic-pelagic carbon cycling directly through their metabolism and indirectly through bioturbation. The on-going changes in the ocean disrupt symbiotic relationships, hamper reproductive success, and influence biodiversity elements and physiological traits of benthic communities. The environmental changes could therefore lead to a different functional role of benthic flora and fauna in key ecosystem processes. Linkages between benthic ecology and ecosystem health including local stressors and global climatic factors, need to be recognised for effective conservation and management strategies of benthic ecosystems in the face of an uncertain future. If you are studying the benthic ecosystems (no matter if fauna, flora, sediment or water) in our changing oceans, you are very welcome in our session!

Marine coastal environments are considered as the most diverse places on Earth. They are subjected to strong dynamic interactions both with the pelagic and the terrestrial environment, and thus more vulnerable to global change and anthropogenic pressure. There is a strong need to understand current ecological processes at different biological scales in the field (individual to ecosystems) and how climate change could modify the physiology, interactions and ecosystem structure. We are looking for researchers working on coastal ecology and/or climate change effect on coastal ecology, using different tools at any biological and taxonomic level. We would like to bring different expertise together to highlight the potential of using complementary approaches for coastal ecology research.

Recognising the pivotal role that coastlines, seas, and the ocean play in human existence underscore the critical need to prioritise marine environmental protection. In response to this necessity, major international organisations such as the International Maritime Organization (IMO) have taken extensive and targeted measures to protect marine life. The current international legal regime in the field of marine environmental protection is governed by a relatively advanced treaty and customary legal system. Advancements in marine environmental law even leveraged developments in other fields of environmental law. Despite international endeavours to lawfully protect the marine environment and biodiversity against pollution, overexploitation, or the effects of climate change, the main question arises: how does international environmental law effectively protect and preserve the marine environment? Join our session to scrutinise critical aspects of marine environmental protection, exploring the international legal order consisting of instruments and organisational initiatives contributing to this paramount cause.

How humans interact with the environment has a considerable influence on marine ecosystems and the associated species. The interconnectedness between human societies and marine ecosystems unravels into multifaceted dimensions, requiring multi- and transdisciplinary approaches to address complex challenges and identify sustainable solutions. Looking through a social-ecological lens, opportunities arise to apply knowledge with innovative resource management strategies that cultivate a positive relationship with nature. Moreover, there is an opportunity to explore best practices and applications across diverse dimensions such as adaptive governance, marine spatial planning, policy formulation, and economic frameworks. Moreover, a discussion on the varying interpretations of sustainable use among stakeholders and communities is essential for advancing the development and utilization of tools for biodiversity conservation. The complexity of the challenges faced requires a balance between human and ecological needs to ensure a sustainable future. In this session, we invite presentations showcasing case studies that exemplify the innovative application of interdisciplinary and participatory methodologies across different scales to address the challenges confronting marine ecosystems. By sharing experiences and insights, we aim to enrich our collective understanding and chart pathways toward a more resilient and thriving marine environment.

Plastic pollution is a significant global challenge in marine environments. It manifests in various forms, from large-scale plastic garbage patches in the open ocean to the widespread presence of microplastics permeating marine waters, organisms, and sediments. The pervasive presence of this pollutant in the seas and oceans poses a substantial threat to the sustainability and health of marine ecosystems, underscoring the urgency for comprehensive action. Addressing this problem necessitates extensive research and collaborative efforts between scientists from diverse research fields.

The main goal of this session is to encourage dialogue among early-career scientists from different disciplines within the scope of marine plastic pollution, highlighting the importance of a multidisciplinary approach in addressing this issue comprehensively. We welcome work from a broad spectrum of research areas, ranging from observational and modelling studies to identify sources and pathways of plastics, to laboratory experiments assessing their impact on the environment and biota and innovative mitigation strategies to combat plastic pollution. This collective integration of diverse research methodologies and insights is a crucial step towards to provide scientific evidences to support target strategy to mitigate and combating this pressing environmental issue.

This session will also create the space for researchers to emphasize the importance of bridging the gap between plastic pollution research and policy implementation, fostering collaboration between scientists, policymakers, and the public to translate scientific findings into actionable strategies.

Marine plastic pollution is a considerable challenge faced across the globe, irrespective of locations and climates. Considerable sources of marine plastic pollution include several industries, such as fisheries and aquaculture. Both fishing and aquaculture industries and other maritime operations are highly reliant on use of plastic materials in various equipment which can result in production in marine plastic litter. Such plastic materials often used by fisheries and aquaculture industries could remain in the ocean for a long time and create macro- and microplastic pollution with associated negative effects on the marine environment. Furthermore, in fisheries, one of the large challenges is pollution caused by abandoned, lost or otherwise discarded fishing gears (ALDFG). Such gear can result in prolonged continuous capture and mortality of marine animals, so-called “ghost fishing” due to use of persistent plastic material in fishing gear construction. This session aims to bring together ideas and previous and ongoing research on marine plastic pollution resulting from fisheries and aquaculture industries or marine operations as well including, but not limited to, pollution rates, ghost fishing, impact of plastic pollution on the marine environment. The session could include a broad range of topics from fishing gear technology related fields up to toxicity caused by microplastics that are resulted from fisheries and aquaculture.

The vastness of our ocean is still largely unexplored, and it is becoming clearer that to unravel its mysteries, scientists need to be able to generate and handle an expansive amount of data. The tools that have become standard in the field in recent years are plentiful. With autonomous technology, we can overcome singular high-cost measurement campaigns and move towards recurring autonomous monitoring of the oceans. Using novel high-accuracy sonars, we are able to monitor swarm characteristics better. Back on shore, we can find correlations in large datasets that would take humans centuries to process. Technology, once an enabling tool to support scientists in their venture into the ocean realm, has transformed into an independent discipline. It now facilitates every aspect from data acquisition to finding correlations in huge datasets. Thus, the scope of this session is supposed to be broad and wide arching. Join us in this broad-ranging session where ocean technologists meet to share innovative solutions from their respective fields. This session aims to be a hub for young researchers, fostering interdisciplinary collaboration and novel ideas. We welcome proposals in ocean technology, ranging from new adhesives to cutting-edge machine learning models, to contribute to a vibrant and constructive community.

Over the past few decades, Remote Sensing (RS) technologies have emerged as pivotal tools for monitoring and assessing health of aquatic ecosystems, estimating water quality and aquatic vegetation parameters by analysing the spectral characteristics of the water bodies and their key components. These technologies offer extensive spatial coverage and frequent monitoring, furnishing near real-time data at a large scale, thereby complementing traditional in-situ measurements. Beyond assessing optically active water quality parameters, RS technologies offer unparalleled capabilities for the retrieval of lake bottom characteristics, turbidity, chlorophyll concentration, dissolved organic matter, and detection of harmful algal blooms. In recent years, spaceborne and airborne hyperspectral imaging, joint with LiDAR and radar sensors, along with the well-established multispectral RS technology, enable mapping and monitoring of aquatic vegetation distribution, abundance, and health, as well as the impacts of human activities on aquatic plant communities. Additionally, the integration of RS data with in-situ measurements are useful to investigate vegetation ecological functions and plant functional traits at different levels. Who should attend: This session is aimed at young researchers interested in advanced remote sensing technologies, real case studies and applications in aquatic environments. If you are involved in environmental activities aimed at preserving precious aquatic ecosystems, this session offers valuable insights, networking opportunities and knowledge exchange in the field of aquatic remote sensing. Join us for an immersive session that explores the potential of Remote Sensing technologies for application in freshwater ecosystems and coastal habitats by crossing a diverse range of aquatic environments, each playing a critical role in supporting life on Earth. This session aims to show innovative approaches and applications in a real-world scenario to address key challenges in water resource management and conservation strategies.

Sclerochronology is known as a discipline that provides baseline data for a variety of life history, ecology, and management studies. Nowadays it’s hard to imagine a comprehensive study on species biology that does not provide a piece of information on its maximum age or growth rates. In paleoclimatic studies, it allows the reconstruction of past environmental conditions. Many stock assessment protocols presume collecting data on the age composition of the stock units. But sclerochronology is much more than a convenient tool! The discipline provides a great variety of insights per se. Analysis of recording or hard structures trace element or isotope composition, modelling of morphological responses in these structures to different environments, and global variation in growth rates of animals, all are just the tip of the iceberg of the variety of sclerochronological studies. Moreover, the field of research has been rapidly developing in the past years, and the dream technologies of the past, like 3D image analysis or modelling of hydrodynamic properties of molluscan shells, become true and even routine. In our eyes, this theme session provides a platform for a broad discussion on the recent advances in all the fields of sclerochronology, from studies on micro- and macrostructure of recording structures to the practical application of the age and growth data in stock assessment. Are there fields of sclerochronological research we didn’t mention here or ones we even can’t imagine? We are excited to hear about it! At the “Sclerochronology – providing insights for life history, ecology, and management studies” theme session we warmly welcome paleontologists, biologists, ecologists, fishery scientists, and everyone who shares our passion for sclerochronological research.
