International Symposium on Deep-Sea Corals 2023

Monday 29th May - Friday 2nd June 2023

John McIntyre Conference Centre - Pollock Halls Estate 

Edinburgh, United Kingdom

ABOUT

We are living in a time of unprecedented change with multiple natural and anthropogenic pressures on our oceans, from climate change to fishing, sedimentation and volcanic activity. In addition to understanding how these pressures have impacted these ecosystems in the past and predicting future impacts, we also need to consider how to integrate planning for sustainable development of a blue economy and what changes are needed to existing policy and governance landscapes. As such, the broad overall theme for the 8th International Symposium for Deep-Sea Corals was ‘Corals in a Changing Ocean’. 

The 8th International Symposium on Deep-Sea Corals (ISDSC8) took place in the John McIntyre Conference Centre, Edinburgh between 29th May and 2nd June 2023. The conference was held in hybrid format to promote discussion between in person and online delegates.

The meeting was attended by nearly 200 participants in-person and around 40 people joining remotely.  Th weeks conference programme included:

  • 9 science sessions
  • 147 talks and speed-talks
  • 62 posters & research highlight pre-recorded presentations
  • 9 workshops

We are committed to providing a friendly, professional, respectful, inclusive and safe environment for all participants at the ISDSC8. The Symposium adopted Code of Conduct following previous ISDSC. Code of Conduct and Social Media Policy

SESSIONS

Session Topics 

1. Evolution, Taxonomy and Systematics

Chairs: Tina Molodtsova & Jeremy Horowitz   

Mitigating anthropogenic threats towards deep-sea biodiversity is difficult because we lack fundamental knowledge on the number of valid species, their systematic relationships, and their evolutionary histories. Contributions are welcomed on systematics, species delimitation, evolutionary history, and the diversification of corals and their symbionts. New technological and/or methodological approaches including the use of historical  DNA are also welcome.


2. Coral Reproduction, Biology and Physiology

Chairs: Rhian Waller & Marina Carreiro Silva 

We welcome contributions on the many facets of deep-sea coral reproduction, larval dispersal including modelling, age and growth studies, biomineralisation, and impacts of multiple stressors including climate change impacts (e.g., effects of ocean acidification and ocean warming) and direct human impacts (fishing and mining). New technological and/or methodological approaches to the field are also welcome, as well as any other aspects of coral biology and physiology.


 3. Trophodynamics and Biogeochemical Cycling 

Chairs: Laurence de Clippele & Sandra Maier 

Contributions are invited on, e.g., in situ and in vivo measurements of deep-sea coral (reef) respiration, nutrient cycling, carbon storage and biomass mapping, benthic-pelagic coupling, food supply and food webs. The session includes work on the organism level and (modelling) at the ecosystem scale and covers deep-sea coral reefs below 200 m water depth, mesophotic reefs and rarophotic reefs. New technological and/or methodological approaches to the field are also welcome.

 

4. Geological Approaches for Coral Biomineralisation, Habitat and Palaeoceanographic Reconstructions

Chairs: Chelsea Korpanty, Guillem Corbera Pascual, Joseph Stewart & Andrea Burke 

We welcome contributions from the diverse geological, palaeontological and geochemical fields investigating deep-sea corals, their habitats and ecosystems. Contributions may range from elemental and isotopic analysis of corals, diagenetic effects, sedimentological analysis, mound growth reconstructions, fossil fauna diversity, and palaeoenvironmental and palaeoceanographic proxies. New technological and/or methodological approaches to the geological fields are also encouraged. 


5. Coral Biogeography and Associated Biodiversity 

Chairs: Andrea Quattrini, Martha Nizinski, Covadonga Orejas 

Contributions that focus on the diverse faunal assemblages, including microbiomes, associated with mesophotic and cold-water corals are welcome. This session also welcomes talks that focus on community assembly of coral communities and coral biodiversity and biogeography. We hope that this session emphasises the progress made since the first ISDSC 20 years ago. We also invite presentations that highlight new analytical and technical approaches, such as environmental DNA, to study biodiversity.  We hope this session stimulates discussion on existing knowledge gaps surrounding coral-faunal interactions as well as chart a way forward to better address these knowledge gaps, predict impending community shifts, and conserve habitats in the face of global change. 


6. Policy, Management, and Conservation 

Chairs: Georgios Kazanidis & Anna Gebruk 

We welcome varied contributions on, e.g., impacts of human activities on deep-sea coral ecosystems, the identification, management and reporting on vulnerable marine ecosystems (VMEs), deep-sea coral restoration, the designation and effectiveness of marine protected areas (MPAs) and other area-based management tools (ABMTs) such as marine spatial planning, strategic environmental assessment and environmental impact assessment, and adequacy of fisheries and deep-sea mining regulations. Contributions on the latest negotiations e.g., regarding the Biodiversity Beyond National Jurisdiction (BBNJ) Treaty, are also welcomed.


7. Seascape Genomics and Connectivity 

Chairs: Alexis Weinnig & Cheryl Morrison 

We welcome contributions of deep-sea coral population connectivity (i.e., population genetics/genomics) and seascape genomics through the integration of connectivity analysis with environmental factors and larval/circulation models to better understand distribution patterns. We encourage contributions that shed light on how these data can inform best management practices. New technologies and/or methodologies to the field are welcomed.


8. Habitat Mapping and Environmental Controls of Deep-Sea Coral Incidence

Chairs: Rebecca Ross, Tabitha Pearman & Ryan Gasbarro 

We welcome contributions on the geology and physicochemical aspects of deep-sea coral habitats, e.g., discoveries of new deep-sea coral habitats, geomorphology, hydrography as well as the use of species distribution and habitat suitability modelling approaches (SDM and HSM, respectively), and drivers of deep sea coral placement to understand present day and future distribution patterns. New technological and/or methodological approaches to the field are also welcome.


9. Deep-Sea Corals in Society 

Chair: Anna Gebruk 

This session welcomes a wide range of contributions on the growth in public engagement and education opportunities since the first Deep-Sea Coral Symposium in 2000, as well as citizen science and the resurgence of submersibles for deep-sea tourism. Also welcomed are contributions on, e.g., open-access data portals, and capacity–building/training needs in an era of deep-sea corals in a changing ocean, ecosystem services and valuations of deep-sea corals.

  • Good practices for estimating damage to deep-sea coral and sponge habitat from existing bycatch data

Chair: Heather Coleman, NOAA 

Date and time: Wednesday 31st May 13:45-17:30. Pentland Room (JMCC) 

Description:  

A common problem internationally is how to best interpret data on bycatch of deep-sea corals and sponges to understand and manage the effects of fishing gear on habitats. Therefore, this workshop is guided by the following goals: (1) Share current good practices regarding the use of fishery-dependent and fishery-independent bycatch data to improve our ability to locate and understand the effects of fishing gear on deep-sea corals and sponges; (2) Identify methods of reducing bycatch and gear interactions through commercial fishery management; and (3) Identify specific research questions and knowledge gaps that need to be addressed for the estimation of fishing impacts and development of management-based bycatch reduction. For this workshop, fishing gears to be considered include trawls, longlines, pots, traps, and others that touch on or near the seafloor. We consider bycatch as coral or sponge material that is brought on board. We hope that sharing international strategies for collecting and interpreting bycatch data will help scientists and managers improve methods of analysis that can inform policies. Desired outcomes from this workshop include a set of relevant international references and a paper summarizing international strategies and agreed-upon good practices. 


  • Image analysis made easy: introduction to a new machine learning software for automatically measuring species area 

Chairs: Poppy Clark, Abraham Smith, Laurence De Clippele 

Date and time: Wednesday 31st May 13:45-15:30. Holyrood Room (JMCC) 

Description:  

This workshop will present an open-source and user-friendly machine learning tool capable of measuring species surface area from images. The workshop will demonstrate the tool’s key features, such as its intuitive training process, in-built metrics calculator and model-sharing capabilities. During the workshop, attendees will be guided through the installation of the tool and gain first-hand experience in training models on a practice dataset.  

Chair: Jennifer Ewald, BOEM 

Date and time: Wednesday 31st May 13:45-15:30. Salisbury Room (JMCC) 

Description:  

 Since its inception in 1973, the Bureau of Ocean Energy Management’s (BOEM) Environmental Studies Program (ESP) has provided valuable information to predict, assess, and manage impacts from offshore energy and marine mineral exploration, development, and production activities on human, marine, and coastal environments. The vision of BOEM’s ESP is to realize ocean stewardship through science. This approach complements BOEM’s mission of managing development of U.S. Outer Continental Shelf (OCS) energy and mineral resources in an environmentally and economically responsible way. The ESP also seeks to align the program with the broader stewardship role the Department of the Interior (DOI) plays in managing the Nation’s public lands—the federal government and ocean users working cooperatively with mutual respect to achieve shared natural resource management goals. Dr. Rodney Cluck and his team will be presenting on the historical program and goals for future collaboration and scientific stewardship. https://www.boem.gov/environment/environmental-studies-program-celebrates-golden-anniversary 

Chair: Hermione Cockburn, Dynamic Earth 

Date and time: Wednesday 31st May 16:30-18:00. Dynamic Earth 

Description:  

This 1.5-hour workshop will explore different models for engaging public audiences with deep-sea science. The workshop is suitable for anyone with an interest in ocean literacy and will draw on examples from recent projects led by Dynamic Earth, Edinburgh’s science centre. It will include ideas and examples of hands-on activities and also cover evaluation techniques. 


Chair: Kristopher Benson, NOAA 

Date and time: Thursday 1st June 14:15-16:00. Pentland Room (JMCC). 

Description:  

This workshop will seek input on applications of data compiled and generated in the first three years of ongoing projects to restore of deep sea coral communities in the Gulf of Mexico that were impacted by the Deepwater Horizon oil spill. Workshop conveners will provide in-depth examples of project team applications including gap analyses to prioritize and direct implementation of specific project activities in specific geographic and locations to meet project objectives and performance criteria. These internally-focused applications support establishment of monitoring, sampling, data collection, and data management standards; sequencing implementation mission and mobilization plans; and assessing progress towards project objectives and overall restoration outcomes. Conveners would like feedback from workshop participants on these self-reflective applications intended or performed by the project teams. Participants are also encouraged to consider and discuss the potential for externally-focused applications of these data as they are made public through open-access portals, and to explore this data management and evaluation effort as a model for others supporting the restoration, protection, and management of deep sea coral communities globally.

Chair: Narissa Bax, Tom Hourigan, Ariane Buckenmeyer 

Date and time: Thursday 1st June 14:15-16:00. Salisbury Room (JMCC) 

Description:  

To standardise deep sea stony coral (Scleractinia and Stylasteridae) data, the Global Ocean Observing System (GOOS) community is developing an Essential Ocean Variables (EOV) specification sheet, to complement the existing shallow hard coral EOV. This effort to monitor and understand the ocean environmental parameters for deep sea corals which are critical to ocean health and biodiversity, is guided in part by the United Nations Decade of Ocean Science for Sustainable Development. The Deep Ocean Observing Strategy (DOOS) and other efforts are helping to coordinate input, including both the national and international regulations and conservation issues driving coral observing needs, and the capabilities to deliver this information.  The final specification sheet should ideally be adaptable to a broad range of research objectives and sampling methodologies, assisting researchers, resource managers, and policymakers in understanding deep sea coral ecosystems and informing conservation management efforts, while also supporting consistent data collection and analysis and interdisciplinary research. As part of this effort, we  invite you to comment on the EOV specification sheet to provide feedback and suggestions, as well as to discuss current challenges and opportunities in deep sea coral research and conservation. This collaborative effort will aid in ensuring that the EOV specification sheet is comprehensive and widely applicable, and that it can support global monitoring and conservation. 


Chair: Michelle Taylor, CORDAP 

Date and time: Thursday 1st June 16:30-18:00. Pentland Room (JMCC) 

Description:  

Prior to the conference, CORDAP hosted a workshop on Restoration and Conservation of Deep Sea Corals. The workshop was a scoping study into deep sea corals, to identify gaps in knowledge regarding deep-sea corals and to develop a roadmap giving recommendations of priority future R&D investment areas and directions. The workshop at ISDSC8 will summarize these findings, and invites ISDSC8 delegates to join them in discussion around this with the aim a roadmap for developing this research area further. 


  • Exploring Opportunities and Implications for Scientists under the BBNJ Agreement: A Roundtable Discussion 

Chair: Christine Gaebel, Deep-Ocean Stewardship Initiative (DOSI) 

Date and time: Thursday 1st June 16:30-18:00. Holyrood Room (JMCC) 

Description:  

In response to growing global concern for marine biodiversity of areas beyond national jurisdiction (BBNJ), the international community came together to negotiate a new international agreement for the conservation and sustainable use of BBNJ. After five years of negotiations, the text of this new agreement was recently finalised in March 2023 and is now awaiting formal adoption. Given the recent finalisation of the BBNJ negotiations, the Deep-Ocean Stewardship Initiative (DOSI) and friends are hosting a roundtable discussion to bring together deep-sea scientists to explore the opportunities and implications for the scientific community under the new agreement. The event will begin with a series of brief presentations, followed by open round-table discussions designed to foster dialogue among attendees. All are welcome to attend and no prior knowledge of the BBNJ process is required. 


Chair: Stephanie Sharuga, BOEM 

Date and time: Thursday 1st June 16:30-18:00. Salisbury Room (JMCC) 

Description

At the Ocean Sciences Meeting 2022, a diverse group of scientists and resources managers from government agencies, academia, industry, and NGOs met to discuss collaboration in ocean sciences. Improving relationships and collaborations by sharing knowledge, capabilities, and resources promotes cross-boundary and interdisciplinary studies, which are becoming increasingly common and needed. Increased collaboration will help create and maintain synergies, as well as reduce repetition and redundancy in research and other initiatives. All of this will ensure the best scientific research is being done as efficiently and effectively as possible and will improve return on investment. This workshop is a continuation of discussions related to collaboration and aims to promote knowledge-sharing and discussions on how to increase collaboration in funding and carrying out ocean sciences.

Post Conference Workshop

  • Cold-water corals in aquaria: maintenance and experimentation.
Data and Time: Saturday 3rd and Sunday 4th June

Description: This capacity building workshop on the 3-4th June aims to provide practical guidance on the maintenance of cold-water corals (CWC) in aquaria, offering an overview of the different aquaria systems, collection methods, feeding and daily care. It also provides talks by experienced researchers working with different CWC species in aquaria, addressing a variety of techniques for ecophysiological research, and using different life stages (adult and larval stages). Researchers will also provide advice on troubleshooting, how to address the challenges of experimental design and how to extrapolate data collected in the lab to the natural environment. We believe this workshop will be valuable to any researcher interested in conducting experimental work with cold-water corals in aquaria.
