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.
Researchers have discovered evidence of water â enough to fill oceans â embedded in minerals deep beneath the surface of the United States that could alter the current understanding of the Earth's composition and how it was formed.he depth of this water is around 400 miles, or 700 kilometers, and the deepest hole ever drilled in the Earth is about 10 kilometers, Jacobsen said. The story has more to do with understanding the composition of the Earth..
