海洋混合被认为控制了具有重要气候意义的海洋翻转环流。在这里，我们认为，海洋生物圈通过一种类似于海洋沉积物中发生的生物扰动的机制，像风和潮汐一样有效地混合海洋。这一说法最终来自净初级生产中向海洋环境提供的估计62.7太瓦特的化学电力。不同的方法认为，大约1%(0.63太瓦特)的电力投资于无光海洋机械能，这一比率与风能和潮汐输入相当。
Ocean mixing is thought to control the climatically important oceanic overturning circulation. Here we argue the marine biosphere, by a mechanism like the bioturbation occurring in marine sediments, mixes the oceans as effectively as the winds and tides. This statement is derived ultimately from an estimated 62.7 TeraWatts of chemical power provided to the marine environment in net primary production. Various approaches argue something like 1% (.63 TeraWatts) of this power is invested in aphotic ocean mechanical energy, a rate comparable to wind and tidal inputs.
