Insight Material

Climate Oceans Environment Environment Hawaii is turning ocean plastic into roads to fight pollution The ocean plastic that washes up on Hawaii’s beaches is recycled into asphalt to pave roads. Ocean acidification is a reduction in the pH of the ocean over an extended period of time, caused primarily by an increase of carbon dioxide from the atmosphere. Ocean warming enhances hurricane activity, bleaches coral reefs and melts Antarctic sea ice. That warming has been off the charts for the past year. Understanding how the ocean works is foundational to understanding life on this planet and to the discipline of oceanography.

Final Conclusion

Get to know the big systems of the ocean: its cycles, circulation, zones, and connection to the atmosphere. Learn about ocean chemistry, life and landscapes on the seafloor, plate movements, shorelines, and icy regions. The ocean is a vast and critical reservoir that supports a diversity of life, helps regulate climate, provides a large amount of the planet’s oxygen, and stores an abundance of carbon dioxide. NASA satellite, airborne, and in-situ missions and projects are constantly collecting data about the global ocean.
