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.
Greenland is much bigger, but it is much colder.. Experts have attributed sea level rise to two primary effects: runoff from the melting of ancient ice fields, such as the Alaskan glaciers, and an ocean expansion due to warming.laskan Glaciers Melting Faster. An estimated 37 cubic miles of ice are disappearing annually from Alaskan glaciers, turning some imposing ice mountains into minor hills and adding to the steady rise in global sea level.
