This is a list of the longest-living organisms that includes oldest individual bioforms. This is usually defined as: ( 1 a) Having a longer life-span than any other known individual species (such as the Methuselah tree) OR. The Jurupa Oak colony is estimated to be at least 13,000 years old, with other estimates ranging from 5,000 to 30,000 years old. 2  A huge colony of the sea grass Posidonia oceanica in the Mediterranean Sea is estimated to be between 12,000 and 200,000 years old.
Greater abundances of solid particles in the water will decrease the depth of light penetration. Therefore, water near the seashore that is more turbid (cloudy) due to particles will show a decrease in light transmission, even in shallow water.
It also increases. This is because the static pressure is increased from the additional weight of water above. This increase in pressure is linearly related to the depth, wâ¦hich at sea level adds about 4.5 psi for every 10 feet of depth.
