Autumn storms help the ocean absorb atmospheric carbon dioxide and stimulate marine life by ‘stirring-up’ the nutrients that feed blooms of tiny marine plants. These microscopic marine plants, or phytoplankton, play a key role in moving carbon dioxide from the atmosphere into the deep ocean, as well as forming the base of the marine food-web. To fuel their growth they absorb atmospheric carbon dioxide and nutrients from the top hundred meters of the ocean. This depletes the upper ocean of nutrients. Understanding the processes of replenishment has preoccupied oceanographers for generations, partly because of suggestions that global environmental change might suppress it....
