There is. A lot of it. But constant turbulence of the surface prevents it from getting too clumped up. Additionally, there are a *lot* of things eating the algae, too, which keep algal populations manageable.

Sometimes those things get out of whack and you end up with [massive algal blooms](https://earth.esa.int/documents/257246/2274906/Algal_Blooms_animation) that cover huge swaths of the ocean.

You rarely see solid mats of algae, though, because of the constant motion and turbulence. Algae that *does* clump together has evolved into different forms that are strong enough to deal with the ocean currents and don’t *look* like algae, like [giant kelp](https://upload.wikimedia.org/wikipedia/commons/f/f8/Sanc0063_-_Flickr_-_NOAA_Photo_Library.jpg), which is, in fact, algae, not a plant.
