Scientists Say That We Have Only Discovered 1/3 Of All The Sea-life On Earth, How Do They Know Its A Third?
The projection is approached by making a statistical analysis of smaller area and then extrapolating the results to the larger area. So, if it has been shown that in one-square mile 66% more species were found than earlier recognized, then the entire ocean may contain 66% more species than currently recognized. This model has been made more accurate by applying the technique to all depths of seafloor within the one-mile area.
