Seems to me a comparatively simple matter to stir up the ocean bottom and thereby fertilize large areas of the ocean that are basically a salt-water desert as far as life goes. That will allow plankton to grow, fish to feed, and organic matter to settle to the bottom, capturing carbon on the way down. The amount of energy required to do that seems about the same as that required to pump oil from off shore drilling sites to the surface. The environmental downside should be minimal, considering that's exactly what happens to make the areas near the Arctic and Antarctic so fertile, were the stormy weather stirs up the ocean bottoms to fertilize that water.
