B) mix carbon dioxide into the water
C) decrease the salinity of the water
D) add nutrients to the water

Question

Quizplus · Accepted Answer

Adding nutrients to the water would increase productivity in the oceanic region. This is because nutrients are essential for the growth of phytoplankton and other primary producers, which form the base of the marine food chain. Adding nutrients to the water, such as iron or nitrogen, can stimulate the growth of these organisms and increase productivity. Pumping oxygen into the water would not necessarily increase productivity, as oxygen levels are typically already high in the ocean. Mixing carbon dioxide into the water would actually decrease productivity, as it would result in ocean acidification and harm many marine organisms. Decreasing the salinity of the water could also have negative impacts on marine life and would not necessarily increase overall productivity.
