Algae Blooms are rapid massive growths of phytoplankton at the water’s surface. Since phytoplankton is the foundation of aquatic food webs, how can this be a negative situation?
Excessive algae eventually run out of nutrients and die
Bacteria decompose dead algae and deplete the dissolved oxygen in stratified water
Draws unwanted animal to the waters edge to feed
The alga depletes the oxygen in the gulf waters

Decrease of oxygen in the gulf waters
Increase of oxygen in the gulf waters
Increase of solid waste in freshwaters
Lack of oxygen in the atmosphere
The primary cause of hypoxia is
Increased amounts of sediment deposits.
Increased levels of fertilizers in the watersheds
Increased amounts of waste production by humans
Increased levels of industrial waste
Freshwater inflow from the Mississippi River provides
Nutrients throughout the gulf
Promotes the growth of phytoplankton
Drives fish out to sea
Attract more sharks
