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.
Antarctica is losing ice mass while gaining ice extent. This is a confusing point to some. There are a few keys that can help us understand what this means in the context of global warming. Land ice is different than sea ice.ntarctica is melting, not growing. In fact the ice mass is dropping at an accelerating rate due to multiple factors including accelerated glacial ice calving rates. The loss of sea based ice allows the Antarctic ice to move faster towards the ocean resulting in an increased rate of loss of the Antarctic ice.
