The current status of environmental requirements for deep seabed mining issued by the International Seabed Authority

Abstract

Up to September 2018, the International Seabed Authority has issued a total of 100 mandatory requirements (published between 2011 and 2015) as guidance for potential future miners when collecting data for their environmental baseline studies during the exploration phase. An in-depth analysis of all current requirements highlights twelve themes covered by multiple requirements: methodology for seabed sampling, methodology for water column sampling, statistical evidence, spatio-temporal considerations, toxicology, modelling needs, genetic studies, species-specificity, documentation and archival storage, impact-related studies, area-based management tools, and comparison and assessment. Within each theme, the relevant requirements are compared with each other to allow a comprehensive assessment of the research effort needed to satisfy all of the 100 requirements.
