Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. The Guin Library Staff compiles and updates bibliographies on several of the estuaries. The web versions of each bibliography are updated monthly. Bibliographies about estuaries not listed here may be available in draft form by contacting the Library: hmsc [dot] library [at] oregonstate [dot] edu.
