The 2022 International Oil Spill Science Conference (IOSSC) was held on October 4-7, 2022, in Halifax, Canada. As a hybrid event, the virtual sessions of IOSSC were conducted on October 13 and 14, 2022. This conference was co-hosted by the Multi-Partner Research Initiative of Fisheries and Oceans Canada (DFO), Industry Technical Advisory Committee (ITAC), and Concordia University. This joint conference with ITAC’s annual meeting was a huge success with over 250 in-person attendees (and another 150+ virtually) from around the world sharing their latest research in the field of oil spill science including spill prevention, contingency planning, and environmental rehabilitation. The conference provided a platform for professionals, scholars and students from the oil spill response community, government, industry, and academia to work together to deal with the challenges in the field of oil spill response.
