Species sensitivity assessment of five Atlantic scleractinian coral species to 1-methylnaphthalene

Abstract Coral reefs are keystone coastal ecosystems that are at risk of exposure to petroleum from a range of sources, and are one of the highest valued natural resources for protection in Net Environmental Benefit Analysis (NEBA) in oil spill response. Previous research evaluating dissolved hydroc...
