Webinars

Thursday, April 16, 10 am US EDT/7 am US PDT/2 pm UTC/3 pm BST/4 CEST/5 pm EEST. Presented by: Kostas Topouzelis of Scidrones. Description: Marine litter is a significant environmental problem that can dramatically affect flora and fauna and have severe economic impacts on coastal communities, tourism, and fisheries. Currently, most mapping protocols for marine litter in the coastal environment rely on conventional on-site sampling, with limited ability to spatially display concentrations of coastal zone marine waste. To provide real-time, actionable data, Scidrones has created the Coastal Marine Litter Observatory (CMLO), an online platform that detects, maps, and monitors marine litter in the coastal zone using Unmanned Aerial Systems (UAS) and machine learning. UAS aerial images – collected using the Scidrones data acquisition protocol and uploaded to the CMLO platform – provide wide area coverage of actual litter, and machine learning algorithms are used to detect marine litter and categorize it (i.e., plastic, paper, metal, cloth, glass and ceramic, rubber, and wood). Marine debris in the coastal zone is then visualized through high-resolution density maps and spatiotemporal analytics, enabling scalable, operational monitoring and empowering stakeholders to take precise, data-driven action for cleaner beaches and coastlines. A free trial covering 1 km of coastline is available, allowing users to test and explore the platform’s capabilities.

Thursday, April 23, at 10 am US EDT/7 am US PDT/2 pm UTC/3 pm BST/4 pm CEST. Presented by: Roland Cormier and Michael Elliott of International Estuarine & Coastal Specialists (IECS). Description: There is long history of multi-disciplinary research dedicated to Ecosystem-based Approaches (EBA) for environmental policies and management plans – these combine to create Ecosystem-based Management (EBM). Research provides valuable insights into environmental impacts and their effects on biodiversity through ecosystem status overviews, impact assessments, and environmental quality reports generated from large data sets and models using conceptual, qualitative, and quantitative methods. Since policies establish the reasons for action and management outlines the priorities to be addressed, it is ultimately technical measures (Ecosystem-based Technical Measures, EBTM) that specify how managers of human activities can best reduce pressures on ecosystems. An applied science approach – Ecosystem-based Science (EBS) – is needed to inform the reliability and effectiveness of such technical measures. This talk will present this EBA-EBM-EBTM-EBS continuum and build on a previous talk given last year on recent advances in environmental science for management (see OCTO webinar July 2025 https://octogroup.org/recent-developments-in-the-sustainable-management-of-marine-resources). Most initiatives and examples presented will be related to marine environments, but some from other aquatic environments will also be used.

Wednesday, April 29, at 11 am US EDT/8 am US PDT/3 pm UTC/10 am COT/4 pm BST/5 pm CEST. Presented by: Lina Gutierrez Cala and Leah Buckley of Global Fishing Watch. Description: With less than 5 years to achieve the global commitment of protecting 30% of the ocean by 2030, transparency and accountability are more important than ever. Access to reliable information about human activity at sea is essential to support the decision-making processes required to meet this ambitious target. This webinar will introduce the Marine Manager platform, developed by Global Fishing Watch in partnership with Donna Bertarelli Philanthropy. The free and open platform serves datasets on vessel activity and presence derived from satellite tracking and imagery sources, as well as environmental datasets. By making these datasets publicly available and easy to visualize and interact with, Marine Manager supports the development and implementation of effective conservation schemes with tangible outcomes, while helping address challenges such as “paper parks” – protected areas that lack the required management and monitoring tools to meet their mandates. As of today, Marine Manager has supported multiple processes, including the designation of critical biodiversity areas, the design and implementation of management plans, and ongoing monitoring efforts. The tool complements local partners’ resources to enhance the protection of key biodiversity areas in the regions in which Global Fishing Watch operates. Through the Marine Manager platform, Global Fishing Watch aims to provide transparent, reliable and accessible information that supports informed decisions and safeguards the ocean for the well-being of the communities that depend on it.

Tuesday, May 19 at 1 pm EDT/10 am US PDT/5 pm UTC. Presented by: Jasmine Fournier of Ocean Sewage Alliance, Description: Nearly half of the world’s wastewater flows untreated into our rivers and oceans, fueling biodiversity loss, threatening human health, and costing the global economy over $4 trillion annually. But here’s the good news: it’s solvable. And eliminating sewage pollution isn’t just good for the ocean; it’s good for business. Clean water means healthier ecosystems, more resilient reefs, and sustainable coastal economies because no one wants more sewage in the ocean. It’s a win-win-win. This webinar will present the vision for a binding United Nations resolution that establishes international standards, unlocks financing, and supports countries in ending sewage pollution at its source. This conversation will explore how a Global Sewage Treaty addresses a root issue across climate, plastics, biodiversity, and water scarcity; how a circular approach can turn waste into a financially beneficial resource; and the growing movement demanding global cooperation on this solvable crisis, and how you can join.
