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.
The news of expanding Antarctic sea ice stole headlines from global warming alarmists who asserted Arctic sea ice had reached its lowest extent since 1979.' (James Taylor). The most common misconception regarding Antarctic sea ice is that sea ice is increasing because it's cooling around Antarctica. The reality is the Southern Ocean surrounding Antarctica has shown strong warming over the same period that sea ice has been increasing. Globally from 1955 to 1995, oceans have been warming at 0.1Â°C per decade.
