Ambient air consists of many gasses, but of that mix, only 19% of it is oxygen. Many applications will require a higher percentage than the 19%. That's where Concentrated Oxygen fills the need.Concentrated Oxygen refers to oxygen which is a minimum of 90% pure with moisture removed to a -100 deg F dew-point.It can be produced from an oxygen concentrator or delivered in a pressurized cylinder bottle.mbient air consists of many gasses, but of that mix, only 19% of it is oxygen.

Globally, it doesnât sound like much â just 0.049 millimetres per year â but if all the sea ice currently bobbing on the oceans were to melt, it could raise sea level by 4 to 6 centimetres. Fresh water, of which icebergs are made, is less dense than salty sea water. So while the amount of sea water displaced by the iceberg is equal to its weight, the melted fresh water will take up a slightly larger volume than the displaced salt water. This results in a small increase in the water level.
But the mountain glaciers have been telling scientists what the West Antarctica glacier disintegration is now confirming: In the coming centuries, more land will be covered by water and more of nature will be disrupted. A full melt would cause sea level to rise 215 feet.During recent ice ages, glaciers expanded from the poles and covered nearly a third of the continents. And in the distant past there were episodes known as Snowball Earth, when the entire planet froze over.hat is because most of the mountain glaciers lie in areas where temperatures are closer to the melting point than they are in Greenland or Antarctica, and so slight warming tips them to melting. Greenland, with 10 percent of the worldâs ice, has enough to raise sea level by 23 feet.
