The Essential Principles and Fundamental Concepts described in Version 3 of this guide represent content that does not fall neatly within traditional science disciplines, but rather supports a focus on integrated science. Many Fundamental Concepts illustrate more than one Essential Principle. This guide presents a vision of an ocean-literate society. Along with the "Ocean Literacy Scope and Sequence for Grades K-12," the "Alignment of Ocean Literacy to the Next Generation Science Standards," and the "International Ocean Literacy Survey," it outlines a framework for achieving Ocean Literacy. This guide describes the seven most important ideas, or Essential Principles, about the ocean that everyone should know. The 45 Fundamental Concepts support and add detail to the Essential Principles. [Numerous individuals, institutions, and organizations have made substantial contributions to the development, review, and promotion of additional components of the Ocean Literacy Framework including the Centers for Ocean Science Education Excellence (COSEE), the National Marine Educators Association (NMEA), the College of Exploration, the Lawrence Hall of Science, and Sea Grant.]
