Large-scale forces shape local ocean life, global study shows
... At each site, scientists dove down 30 to 50 feet
below the surface. Then they took standard-sized (18 by 24 inches) photographs of a rock wall area. They took anywhere from 18 to 200 of these photo samples at each site. Back in the lab, they examined a total of 1,500 slides and counted the species ...
