neOcean was launched in January 1998, during the International Year of the Ocean, to showcase the Coastal Resource Management Project (CRMP). It has since evolved into a rich and comprehensive resource on the Philippine experience in coastal resource management, which spans over two decades and is looked up to for models of best practices in community-based and local government-driven coastal management.

Under CRMP, OneOcean documented and made available to the Internet public a wide collection of information tools and resources on CRM and other environmental concerns, serving as a "virtual library" where Internet users can readily access and download valuable guidance documents. For this, it was named the Best Environmental Web Site by the 2nd Philippine Web Awards (1999), and received an Award of Excellence (PR Tools - Electronic and Interactive Media-Web Pages/Home Pages) from the 35th Anvil Awards (2000) of the Public Relations Society of the Philippines.

With the completion of CRMP in 2004, OneOcean now serves as the web site of the Fisheries Improved for Sustainable Harvest Project (FISH), documenting experiences and lessons from the FISH Project's implementation, while maintaining the rich information resource developed during CRMP's time (1996-2004).
