Ocean Clean-up Symposium 2019

17th - 19th December 2019

The Institute for Risk and Uncertainty at the University of Liverpool is planning to host a symposium and workshop on risk tradeoffs, with the removal of plastic pollution from oceans such as by The Ocean Cleanup project as the main example.

There will be three related events over three days. The symposium will introduce and explore the issues from many perspectives, including those of proponents from environmental groups and ocean ecologists. The workshop will be a collaborative event in which we will articulate risk analyses to address those issues. These analyses will employ stochastic demography, including uncertainty propagation for abundances, vital rates, and other variables that are known imprecisely.

We believe that finding quantitative answers to the questions of whether and by how much the benefits from plastics removal outweigh the potential risks to ocean organisms, and how they compare with harms from unabated accumulation of oceanic microplastics, can only be answered by modern quantitative environmental risk analysis at the interface between engineering and ecology.

On Thursday 22nd November the Risk Institute held a seminar posing the question: Should we remove plastics from the ocean's surface?

The increase in plastics in the oceans is a major area of concern for marine biologists. In an effort to address this problem, the startup firm Ocean Cleanup is already at work collecting plastics from the ocean's surface. However, any such operation is also likely to affect ocean surface organisms. Is the net effect on ocean surface organisms benign or adverse? Matt Spencer will present a model for this effect. This was a warm-up event for the symposium in December.

Event Layout

The event will be spread over three days, commencing with a symposium discussing the impact of plastics in the ocean and the efforts to remove them. A major factor that has been neglected in many environmental impact studies is how groups such as The Ocean Clean-up will effect neuston species who thrive on the surface of the oceans. This is gap in our understanding of this situation is compounded by a lack of demographic studies on these diverse species of plants and animals. Dr. Rebecca Helm, a specialist in jellyfish biology and critic of The Ocean Clean-up, will present the keynote lecture discussing how neuston have adapted to changes in their environment, and how the well-intentioned efforts to remove plastics may endanger this poorly understood ecosystem.

Our second day will start with talks by Scott Ferson, Matt Spencer and Megan Powell to frame the nature of an upcoming paper. Problems with The Ocean Clean-up's current system will be discussed, and the factors that will need to be taken into account when developing a model of it's impact on a variety of species. Following this, a "Hackathon" style workshop will ensue, with students and researchers alike splitting into groups to solve the proposed problems and contribute to development of a new model, building upon the work an international research team.

On our final day, the Risk Insitute will host a morning social of coffee and breakfast. Open to everyone, we can unwind before concluding the session with the second half of our "Hackathon". Teams will be allowed to present their models and discuss how they account for the variety of issues that can arise from placing a wall in the ocean. The research team will consolidate this information and identify which approach may work best, with the winning team having their work incorporated into a future research paper. After the event, attendees are invited to join us for an evening of dinner and drinks.
