Pumping nutrient rich water from the deep ocean to the surface is one proposed way of increasing ocean productivity to repair fish stocks and sequester carbon.<p>This volcano has provided a natural demonstration of this effect.<p><a href="https://en.wikipedia.org/wiki/Ocean_fertilization" rel="nofollow">https://en.wikipedia.org/wiki/Ocean_fertilization</a>
very interesting! could someone explain why the hot water would lead to deep, cold water being brought to the surface? I thought hot water is less dense than cold water. Wouldn't it just sit on the surface for a long time?<p>Or is there just such a large amount of this extremely hot water that the mixing overtime generates movement across the board?
