Nope, massive amounts of nutrients from sewage and farm runnoff cause massive algal blooms.
Dude.. you seem to only believe the ocean consists of that which you can see from the shoreline..

SURE.. there are oxygen depleted zones that are created by EXCESSIVE nitrates and plentiful supply of Iron in that estuarial run-off.. The kind of algae that is create is NON-Diatomic .. They lack the hard shell structures that would make them sink to the bottom when they die. So they actually decay on the surface, and that decomposition depletes the surrounding water of oxygen (and creates methane as well).

You need phyto-plankton that produce hard structures that make them heavier than the surrounding water when they die, thereby creating MARINE SNOW that sinks to the bottoms...

There are any number of kinds, but the most common are Coccolithophores, which produce calcium CARBONATE structures.

Diatoms produce Silica based structures. Silica is often another limiting factor, like Iron. So an Iron Silicate formula would promote Diatom growth..

Here.. this explains it pretty well for a College Freshman.. Hope it's not too advanced for you.. ;)

And if you are feeling particularly curious (between beers).. Research Oceanic Salps and see what they love to eat and what happens to their fecal pellets..
