Why do algal blooms frequently occur during spring and fall in temperate oceans?
What will be an ideal response?
Algal growth is limited by nutrient availability (usually nitrogen and phosphorus), light availability, and dissolved carbon dioxide concentrations. Since available light levels in the spring and fall are less than in the summer, it is not the changing light levels that are responsible for spring and fall blooms. During the spring and fall, storms frequently mix the water column in shallow coastal seas bringing nutrients to the surface that stimulate algal growth.
