They contain saltwater and have been called seas for many years, but many oceanographers and geographers are more inclined to call them lakes. Still, that leaves dozens of water bodies that fit the traditional definition of a sea, even though they can be quite different from one another. A sea can be more than 2. Or, it can be as tiny as the Sea of Marmara, which is less than 12, square kilometers 5, square miles in area.
A sea can also be very warm for most of the year. The Red Sea, for instance, has an average temperature of around 30 degrees Celsius 86 degrees Fahrenheit. It is also the saltiest sea, containing 41 parts of salt per 1, parts of seawater. Seas can be quite cold, too. The Greenland Sea, for instance, has surface water that hovers near the freezing mark most of the year. It contains a unique mixture of saltwater and freshwater, making it the largest brackish water body on the planet.
As a result, the Baltic Sea contains a small, but rare, variety of freshwater and saltwater plants and animals that have been able to adapt to their brackish environment. She was part of the crew aboard the exploration vessel Nautilus , a ship that shared its scientific discoveries in the Mediterranean Sea, the Black Sea, and elsewhere with students around the world in online lessons and chats.
She says the seas—big and small, cold and warm—can teach scientists about the rest of the world. The audio, illustrations, photos, and videos are credited beneath the media asset, except for promotional images, which generally link to another page that contains the media credit.
