Facts About Oceans

1.  The United States ocean economy produces about $282 billion in goods and services. Ocean dependent businesses employ almost 3 million people. (

2.  The ocean is a giant buffer for temperature and is a “carbon sink”, meaning it can absorb CO2 from the atmosphere without much change in acidity; however with climate change, the ocean is getting warmer and more acidic, causing coral bleaching and slower growth rates of calcifying organisms.  (

3.   About 140 million square miles or nearly 71% of the Earth surface is covered by oceans. ( ocean_facts.htm)

4.  The average ocean depth is 12,200 feet. ( ocean_facts.htm)

5.  Although tap water freezes at 0° Celsius/32° Fahrenheit, seawater does not freeze until about minus 2° Celsius because 3 percent of the ocean is salt.  (

6.  Microplastics are small plastic pieces less than five millimeters long which can be harmful to our ocean and aquatic life. Microplastics are found in many health and beauty products. (

7.  Many serious coral reef ecosystem stressors originate from land-based sources, most notably toxicants, sediments and nutrients. (

8.  Fifty percent of the United States (in terms of complete jurisdiction, which includes ocean territory) lies below the ocean. (

9.  The deep sea is the largest museum on Earth: there are more artifacts and remnants of history in the ocean than in all of the world’s museums combined. (
