What event's typically contribute to an algal bloom in a lake or an ocean?

In fresh water radical changes in PH balance. It can be due to pollution in freshwater environments where stagnant water provides a good habitat for algae and acidic pollutants encourage growth. Red tides are not due to pollution though. They are caused by natural changes in salinity, temperature and nutrient levels that allow Karenia brevis algae, the culprit behind red tides, to grow exponentially. It's still not fully understood what causes such increases but many theories regard high temperature, a lack of wind and rainfall as major factors.

What causes algal bloom?
Algal Blooms are caused by over fertilization, runoff.
Which season do algal blooms mostly occur?
Not all flowers bloom in spring. Those that do so largely because they need to set fruit or seed and have it mature before winter. In the winter, the fruits would not be able to withstand the cold and freeze. Sometimes, the flower's petals will wither during and die in the winter, so they must bloom during the spring, the season of warmth and new life.
Why algal blooms occur?
Fertilize runoff
What are red tides caused by?
Red tides are a natural phenomenon caused by an increase in the amount of nutrients that algae need usually due to farm runoff. When the amount of nutrients reaches a certain level there is a significant increase in Karenia Brevis algae. Many also believe that red tides occur when there is a combination of very high temperatures, wind, and rainfall.Red tides is mostly caused by the increase of temperature and the difference of temperature between hot surface and a cold layer beneath the hot surface. When it is night, the dinoflagellates move to the cold layer to absorb nutrients. When it is day, they move to top to photosynthesize.Red tides are caused by algal blooms. Certain types of algae in the ocean multiply at rapid rates, typically by excess nutrients found in the water. The algae die and the decay process consumes the oxygen in the water -- one of the reasons these red tides are so destructive.By the way, not all algal blooms are red. It all depends on the algae present which grow quickly.A bloom of red algae, usually due to increased nutrients in the water.These extra nutrients can come either from natural sources or human caused pollution.The red algae both deplete oxygen in the water and produce toxins, which kill fish and other sealife. The toxins can also kill people if they eat seafood (especially filter feeders e.g. clams, mussels, oysters, scallops) caught during the period of the red tide or immediately afterwards.
What is a algal bloom that occurs in the ocean called?
when there is an excess of nitrogen (for example when all the snow melts in the spring and washes nutrients into bodies of water), blue green algae / Cyanobacteria can grow very rapidly and essentially coat the surface of the water. This creates problems for any underwater vegetation because the sunlight it needs to grow is being blocked out by all of the algae growing above it. This problem is reflected in all of the species of animals that eat the vegetation and etc down the food chain, because cyanobacteria is not good food for zooplankton and fish. Eventually the blue green algae will run out of nutrients and will die off and the bacteria that bloom to consume the dead blue green algae consumed oxygen and in extreme situations the oxygen supply in the body of water (in smaller closed off bodies such as ponds or lakes) can be depleted by all of the dead decomposing algae and this can kill fish and other species.
What events typically contribute to an algal bloom in a lake or an ocean?
A decrease in the populations of the things that eat the thingies.
What can happen after a lake receives a large amount of limiting nutrients?
an algal bloom.
What is unnatural related to humans about an algal bloom?
Some of the algae that makes up an algal bloom can be toxic. This would probably be the main difference between an algal bloom and humans. Hope this helps!
What is alga boom?
An algal bloom is a rapid increase or accumulation in the population of algae (typically microscopic) in an aquatic system. Algal blooms may occur in freshwater also.
What causes algal bloom?
Algal Blooms are caused by over fertilization, runoff.
What is bloom growth?
There is an article on algal bloom in Wikipedia which is very comprehensive. Bloom that is not of a floral nature usually refers to algal bloom which occurs in acquatic environments where the oxygen levels are depleted.
An overpopulation of saltwater algae is called a?

What impact if any would an algal bloom be likely to have on its ecosystem?

What is the scientific name for an Algal Bloom?
The scientific name for an algal bloom is "phytoplankton bloom." This phenomenon occurs when there is a rapid increase in the population of algae, leading to the visible discoloration of water bodies.
What happens during an algal bloom?
When algae rapidly produce
