Let me tell about these ice sheets. They have a mass of glacier ice which covers the terrain. The terrain has a total of more than 50,000 square kilometers. That is 19,305 square miles. There are only two ice sheets currently. Those are in Antarctica and Greenland. Since the last ice age happened it covered many parts of Canada and North America. There was an ice sheet that was called the Weichselian ice sheet which covered Northern Europe. The Patagonian ice sheet was another one which covered South America.
The Antarctic ice sheet is the biggest mass of ice on Earth. The ice sheet that is in Greenland covers 83% of the land. If the ice melts it would rise above sea level by 7.2 meters. The rate at which the ice melts is about 239 cubic kilometers per year. Ice sheets are even bigger than glaciers.
An ice cap is something that feeds a series of glaciers around it. They cover less than 50,000 kilometers . The surface of an ice sheet is typically cold but the base of the ice sheet is somewhat warmer. It is warm because of geothermal heat. Because of the hotter side, the ice tends to melt and it will begin to flow at a faster rate. That is what we call ice streams. www.sciencedaily.com/articles/i/ice_sheet.htm

Phytoplankton
Most Phytoplankton are too small for the human eye to see them. Phytoplankton obtain energy through a process which is called photosynthesis. They are very much like plants. Phytoplankton (or plankton) live in the surface layer of the ocean. They may be in the sea or lakes as well. Because the process, photosynthesis, plankton are responsible for most of the oxygen on Earth's atmosphere. Even though they are really small, they play a huge role in our lives.
Planktons energy in carbon compounds is the basis for the majority of freshwater food chains. There are different types of phytoplankton. The most common kinds are diatoms. Baleen whales in the ocean eat a lot of plankton. It is mostly because they are on the surface of the water. Phytoplankton depend on minerals. The minerals would be nitrate, phostrate, and silicic acid. Plankton are very limited in the oceans.

Ocean Currents
In this article we will talk about the currents in the ocean. Currents are generated from the forces that are in the ocean. This is because the earth's rotation. It is also because the wind, the temperature, and the gravitation of the moon. All these things cause how tong and the direction the current will go. These currents can flow for as many as a thousand kilometers. The best example of currents is in the Gulf stream. The currents there are very strong.
Deep ocean currents are driven by density. They are also driven by temperature and gradients. Thermoline circulation (the oceans conveyor belt) refers to the deep ocean density ocean currents. Another thing you may want to know about currents is that they flow under the surface of the ocean. They are mostly hidden from the immediate direction. These are called submarine rivers. www.sciencedaily.com/articles/o/ocean_current.htm

Sea Water
Sea water. It has a salinity of about 3.5%. This means that for every liter of seawater there are 35 grams of salts. The freshest water on earth is the Gulf of Finland. The most open saline sea is the red sea. In 1715, Sir Edmond Halley proposed that salt and other minerals were brought into seas by rivers. He thought that this happened by the rain. His theory is not all correct but it was a good theory. You can find this article at www.sciencedaily.com/articles/s/seawater.htm

Saving Fiji's Coral Reefs
There is only 3 percent of land in Fiji. So that means most of it is water and inside that ocean are coral reefs. No one in this country has been protecting these reefs. In 2008, a committee in Fiji came together to protect 20 percent of the land and 30 percent of the ocean. They would do this by 2020. By protecting the reefs they had to make sure nothing could get near it that would hurt them. This was probaly very hard to do. With their help, a lot of fish were protected in this process. www.sciencedaily.com/releases/2013/12/131217155329.htm
