If you have responsibilities in a subject that deal with environmental/earth science topics than I encourage you to give this product a try. The link above will take you to a description of new content and changes over the summer.
This month at columbia earthscape we publish a new batch of reports about water ecosystems. The Preliminary Report of the U.S. Commission on Ocean Policy provides a comprehensive review of policy regarding oceans and recommendations for future reform. Reports from government and non-profit organizations highlight challenges such as invasive species, pollution, global warming, and natural disasters to the world's saltwater and the freshwater environments. Visit the newly updated Hydrosphere section of columbia earthscape's course content for even more content for use in the classroom.
Also, this summer we've revamped the search engine. We invite you to test out the added functionality. New features of search include the ability to search by subject, by region and by publication format. The subject list covers everything from agriculture to oceans.
