New contaminants as well as common contaminants have been continuously emerging in our coastal and marine ecosystems.  The new contaminants such as micro-plastics, pharmaceutical products, and hormone disrupting agents, as well as the more commonly recognized pollutants (e.g. heavy metals and organic pollutants) will be discussed in this session. We will accept papers in the areas of: (1) elucidation of source, behavior, fate and eco-toxicity of contaminants; (2) evaluation of contaminant impacts and toxic mechanisms to marine organisms; (3) development of methods of detection, monitoring, and modelling of contaminant fate at individual to ecosystem levels; and, (4) development of biological indicators, ecosystem health indices, and remediation techniques. 
C14: Ocean Acidification and its Impacts on Marine Ecosystems

The Western Pacific is among the richest in marine biodiversity in the world, and provides essential ecosystem services, such as food security, livelihoods, and coastal protection to the region and beyond.  Climate change is a major concern, especially its impacts on the marine environment through ocean acidification and warming.  The recent UN Sustainable Development Goal 14 also stressed the need to “minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels”. Since 2014, WESTPAC, through its SEAGOOS, has initiated symposium, trainings, workshops on ocean acidification across the region. The session will invite presentations on ecosystem responses to ocean acidification, an understanding of which is critically needed to develop meaningful projections on future impacts of ocean acidification on marine ecosystems, especially on coral reefs.  This will enable resource managers and policy makers to develop effective long-term mitigation and adaptation strategies in the region, Experts and young scientists who are interested in ocean acidification will have an opportunity to share scientific findings and exchange knowledge.
C15: Harmful Algal Blooms

Harmful Algal Blooms (HABs) have been increasingly reported in the countries of the Western Pacific. The socio-economic impacts of HABs are clearly evident, varying from the closure of commercially important molluscan shellfish due to contamination of marine biotoxins, and economic losses amounting to millions of dollars due to massive fish mortality, either wild or caged. This session is intended for researchers, aquaculturists, environmental managers and other stakeholders to discuss about and exchange the latest knowledge on HABs. Presentations shall cover various aspects, ranging from recent red tide and fish/shellfish poisoning cases, taxonomy and ecophysiology of HAB organisms spanning from laboratory settings to field investigation, causes of HABs such as climate change, socio-economic impacts of HAB events, to the latest development and application of advanced molecular tools for species detection. New and emerging HAB events will be highlighted in this session.
C16: Remote Sensing in Integrated Coastal and Marine Management

Escalating human activities have been posing considerable threats to coastal and marine ecosystems and resources. Given the advantage of remote sensing in observing large area in a relatively short time, it has a wide range of applications in coastal and marine resource management, including shoreline change monitoring, sediment transport tracking, coastal habitat mapping, ocean temperature monitoring and disaster risk reduction etc. The latest technologies such as Unmanned Aerial Vehicles (UAV), new-generation satellites and related sensors have also shown great potential. This session invites presentations on the development and advancement of remote sensing technologies, the validation of remote sensing data and products, and the application of remote sensing in coastal and marine management.
C17: Rehabilitation and Conservation of Marine Ecosystems

Conservation of marine ecosystems against anthropogenic pressure remains as one of the most prevalent challenges for the WESTPAC region and is expected to be aggravated by climate change impacts. Various conservation including rehabilitation tools, methods and approaches have been adopted in the region as countries strive to meet the Aichi Biodiversity Targets of the Convention of Biological Diversity. This session focuses on the conservation and rehabilitation initiatives that have been implemented. The wealth of experience is enormous considering the diversity in scope and scale of such measures. Presentations are invited from those who are or have been involved with conservation and/or rehabilitation projects or programs. Papers are strongly encouraged on the following topics:
1) Innovative approaches and methodologies in conservation and rehabilitation
2) Conservation and rehabilitation that take into account resilience to anthropogenic impacts and climate change
3) Analysis of factors that lead to success or failure in conservation and rehabilitation projects.
