Through reports, articles, a glossary, and 80+ links, the Online Clearinghouse for Education & Networking: Oil Interdisciplinary Learning (OCEAN-OIL) explores the causes, magnitude, and consequences of the world's largest marine oil spill, as well as offshore drilling and the use of energy and society. The site is open-access and peer-reviewed — funded by the National Science Foundation and created by Boston University, Louisiana State University, and the National Council for Science and the Environment.
