Tiny creatures, massive impact: How zooplankton store 65 million tonnes of carbon annually

Zooplankton, including species like copepods, play a crucial role in the ocean's carbon cycle, far beyond their reputation as mere fish food. These tiny organisms are responsible for storing an astounding 65 million tonnes of carbon each year. As they engage in their daily vertical migrations, zooplankton transport carbon from the ocean's surface to its depths, effectively acting as natural carbon sinks. Every winter, these minuscule creatures undertake a remarkable journey, diving deep into the ocean's colder waters. This seasonal movement is more than just a survival tactic; it is a significant mechanism for carbon sequestration. By descending to the ocean depths, zooplankton help trap carbon dioxide that has been absorbed by surface waters, preventing it from re-entering the atmosphere and contributing to climate change. The impact of zooplankton on the global carbon cycle underscores the importance of preserving marine ecosystems. These organisms not only support the marine food web but also play a vital role in regulating the Earth's climate. As research continues, understanding and protecting these carbon-hauling powerhouses could be key to mitigating the effects of climate change and ensuring the health of our oceans.
