A healthy ocean starts with us. Posts will feature actions we can take to improve the health of the ocean, as well as actions not to take.
How much do you know about our ocean? Get ready to test your knowledge from how many ‘oceans’ there are (just one!) to what makes the ocean blue, and other head-scratching questions.
From bioluminescence to brain coral, the ocean is teeming with incredibly diverse life. Take a fun dive and meet some interesting ocean creatures.
What is sonar? What does an oceanographer do? Find out the answer to these and other questions as we delve into the science of the ocean.
What do you know about our ocean? The ocean is where life began over 3.5 billion years ago. The ocean covers over 70% of the Earth's surface and includes over 96% of the Earth's water. Australia's Great Barrier Reef is the largest living structure on Earth and can be seen from the moon! The deepest part of the ocean is in the Mariana Trench, and nearly 7 miles beneath the waves! Coral reefs cover only 1/50th of the ocean floor but about one quarter of all the marine species make coral reefs their home. No light penetrates the ocean at depths greater than 3,280 feet. Aided by deep diving rovers and remote sensing cameras, scientists are still discovering new species beneath the waves. The Gulf Stream transports more water than all of the Earth's rivers combined. The mid-ocean ridge crisscrosses the globe for over 40,000 miles and is the largest geological feature on Earth. Did you know that about 95% of the ocean remains unexplored? There is only one world ocean. Happy World Ocean Day from NOAA's National Ocean Service.
