WebIn the Arabian Sea, the monsoons and strong winds impart a lot of energy into the ocean, creating fast and dynamic ocean currents. These currents interact with the complex seabed morphology of steep cliffs and canyons, and sometimes lead to transport of deep water to the shallows. Uniquely, deep waters in the region are very low in oxygen, leading to … WebAlgal blooms occur when water conditions are ideal for phytoplankton growth. Therefore, blooms tend to occur when water is relatively warm and full of nutrients. Algal blooms become harmful when the phytoplankton produce toxins that cascade through trophic levels. The species Pseudo-nitzschia produces a neurotoxin called domoic acid. WebChanges in rainfall and temperature could increase nutrient runoff while decreasing water volume and warming water temperatures, thus creating conditions that encourage algal growth. Decreased fertilizer use and improved timing will be crucial for controlling algal blooms in the future. shared ownership pinner
