Document Summary
Within the ocean, diversity are heavily skewed towards things living on the ocean floor even though the bulk of the water column is in the ocean. Only about 2% is actually in the water column. Diversity - even things that are living in the open ocean are hanging out closer to shore because there is coastal upwelling and nutrients flowing from the continents. By and large on the continental shelf. Diversity is lower in the open oceans. Rocky and soft intertidal has the importance of zonation due to the influence of waves, tides, sun, air, temperature, pressure, predators, etc. Diff types of subtidal ecosystems - dependant on some kind of producer (kelp, coral, sea grass) Non photosynthetic reef organisms that live on the slope. Abyssal plain is relatively devoid of activity - waiting for things to fall for bottom or filter feeding. Chemosynthetic communities got their energy from the hydrothermal.
