17th ICMCF Session Topics Biology of Fouling Organisms Chair: Dr Nick Aldred, Research Associate, School of Marine Science & Technology, Newcastle University, UK. [nicholas.aldred@ncl.ac.uk] From single-celled organisms to macroalgae and sessile marine invertebrates, the focus of this session is the biological adaptations of fouling organisms that enable them to locate, select and attach to surfaces, identify or attract conspecific individuals, deter predators or epibionts, resist contemporary antifouling approaches and reproduce/disperse in a manner that exacerbates the fouling challenge. Talks may focus at the individual or the community level to provide insight into potential fouling mitigation strategies. Fouling as a vector for invasive species Chair: Dr Eugene Georgiades, Senior Adviser, Biosecurity Risk Analysis (Animals and Aquatic), Science and Risk Assessment Directorate, Ministry for Primary Industries, NZ [Eugene.Georgiades@mpi.govt.nz] Vessel biofouling represents an important vector for the spread of non-indigenous species. The introduction of some non-indigenous species to new locations can have far-ranging impacts on the marine environment and the people reliant upon it. This session aims to provide scientists, regulators and end users with new information regarding: • the transport of non-indigenous species via vessel biofouling; • their associated impacts; • the risks associated with different types of vessels or hull treatments; and, • new developments, both regulatory and technical, to address this problem. Microalgal fouling and adhesion processes Chair: Professor Jim Callow, Emeritus Professor of Plant Science, School of Biosciences, University of Birmingham, UK. [j.a.callow@bham.ac.uk] This session is concerned with all aspects of fouling and adhesion processes that concern microalgae, or the microalgal fouling stages of macroalgae. Contributions may range from cellular and molecular processes involved in recruitment and adhesion, up to studies on the dynamics of microalgal communities such as those responsible for diatom slimes. Developments in novel coating technologies to control microalgal fouling and the formation of slime layers are also relevant. Marine Bioadhesion Chair: Dr Gary Dickinson, Assistant Professor, Dept of Biology, The College of New Jersey, USA. [dickinga@tcnj.edu] Adhesion is a matter of life and death for a wide range of marine organisms. Barnacles, sea weeds, oysters, starfish, mussels, limpets, and tube worms (among others), have evolved remarkable physical and biochemical mechanisms that enable secure attachment in a wet environment. Understanding these mechanisms may foster development of antifouling coatings that interfere specifically with the bioadhesion processes. This session will focus on recent insights on the biochemistry, biology, chemistry, interfacial contacts, and mechanics of marine bioadhesives. Biofilms and microbial fouling Chair: Professor Peter Steinberg, Director, Sydney Institute for Marine Sciences; Co-Director, Centre for Marine Bioinnovation, UNSW, Australia; Co-Director, Advanced Environmental Biotechnology Centre, NTU Singapore. [p.steinberg@unsw.edu.au] This session will focus on the ecology, biology and control of microbial communities on marine and aquatic surfaces. Topics will include mechanisms of biofilm formation and development, the use of meta’omics techniques for characterising structure and function of microbial communities and interactions within biofilms. Studies of control mechanisms will include novel approaches to interfering with biofilm formation, structure or dispersal. Microbiologically influenced corrosion Chair: Associate Professor Daniel J. Blackwood, Dept of Materials Science & Engineering, National University of Singapore, Singapore. [msedjb@nus.edu.sg] This session aims to present recent developments in understanding fundamental mechanisms of microbiologically influenced corrosion (MIC).

Risk management in marine corrosion Chair: Dr Brenda Little, Senior Scientist, Naval Research Laboratory, Stennis Space Center, USA. [Brenda.Little@nrlssc.navy.mil] Corrosion risk management in the marine environment is an essential tool for corrosion and materials engineers, requiring prediction, material selection, design, monitoring and mitigation (e.g., coatings and cathodic protection). The session invites papers on tested methodologies and innovative approaches for corrosion risk prediction and management. Biofouling and Corrosion in the Offshore Oil & Gas Industry Chair: Mr John A. Lewis, Senior Associate, ES Link Services, Australia. [jlewis@eslinkservices.com.au] Offshore facilities for oil & gas recovery have projected operating lives of up to 30 years, and project designs are increasingly utilising new engineering and technological innovations to increase production efficiency. Predicting biofouling impacts over this timeframe in the offshore realm is difficult. This session calls for papers on the accumulation, distribution and composition of biofouling on offshore rigs, floating storage and processing facilities, subsea pipelines, and other deep water structures, on corrosion and corrosion control for offshore structures, and on coatings and materials for biofouling and material protection to enable facilities to achieve their design life. Fouling in desalination and seawater cooling systems Chair: Dr Richard Piola, Defence Scientist, Maritime Division, Defence Science and Technology Organisation, Australia. [richard.piola@dsto.defence.gov.au] This session will focus on challenges and opportunities concerning technologies for the management of biofouling in desalination and internal sea water cooling systems, including power plants and ships. Many of these systems experience unique biofouling pressures which present challenges for the research and development of effective treatment strategies. This session aims to bring together industry representatives and science and technology professionals to discuss improvements to current treatment methods and development of emergent technologies for effective biofouling treatment outcomes in these highly critical system environments. Fouling in Aquaculture Chair: Dr Belinda Yaxley, Petuna Aquaculture Pty Ltd Biofouling is a serious problem in the aquaculture industry. Fouling organisms compete with cultured stocks for food and space in culture pens, as well as harbour pest and disease vectors. Due to human health concerns, application of antifouling poses challenges for the industry as there is limited scope for use of bioactive substances. This session will focus on challenges in managing biofouling in the aquaculture industry and new antifouling approaches.
