Aquatic organisms depend on the level of oxygen dissolved in water. Even if water is saturated with oxygen, (containing as much O2 as it is capable of holding), it may contain less than 5% oxygen. The air we breathe contains 21% oxygen. Many factors can affect the oxygen content of water. Turbulence, temperature, organic matter and plant growth all influence daily and seasonal oxygen levels.
The graph to the left shows the dissolved oxygen measurements from 10 Bay of Islands sites in the years 2005 & 2006.
The data used to generate the graph was collected in the Fall season of 2005 & 2006.
