Whale feces dioxide which holds an estimated 90% of all sequestered carbon. The Southern Ocean is amongst the largest ranges for phytoplankton and has the characteristic of being nutrient-rich in terms of phosphate, nitrate and silicate, while it is iron-deficient at the same time. Increases of nutrient iron results in blooming of phytoplankton.
