The mask, dubbed Triton, acts like a fish gill to extract oxygen from water so that the user can keep on breathing while under the sea. The scaly texture on the arms conceal small holes in the material where water is sucked in.
Bacteria in the water use oxygen to break down this organic material. When there is a lot of organic debris, the dissolved oxygen in the deeper water can be used up. If the water at the surface (which has plenty of dissolved oxygen) is not mixed with the deeper water layers form and the water becomes stratified.Then there is no new dissolved oxygen for the deep water. When this happens, the deep water can become unhealthy.old water can hold more dissolved oxygen than warm water and fresh water can hold more dissolved oxygen than salt water. So the warmer and saltier the water, the less dissolved oxygen there can be. The maximum amount of dissolved oxygen that the water can hold is called the saturation value.
