Discover the ocean learning hub—your gateway to trusted ocean science content Easily explore by topic, media type, grade level, and educational standards. 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. Without the ocean, life as we know it wouldn't be possible There are a number of key reasons why
First, the ocean is the largest source of oxygen on earth According to scientists, approximately half of the planet's oxygen production originates from the sea Most of this oxygen is created in the top 200 meters (656 feet) of the ocean's surface Within this depth, sunlight penetrates. Understanding how the ocean works is foundational to understanding life on this planet and to the discipline of oceanography Get to know the big systems of the ocean
Learn about ocean chemistry, life and landscapes on the seafloor, plate movements, shorelines, and icy regions. Why is the ocean blue People have wondered this for hundreds of years One idea is that it reflects the sky From the coast, it may appear a deep blue on a sunny day Or gray when it's stormy
Or even turn a brilliant pink during sunrise or sunset But if we sink below the surface, the blue color remains Here, the water isn't reflecting the sky Dive in and find answers to your deepest ocean questions Get the facts and increase your ocean knowledge.
