Algal bloom

In an advancing twenty first century, technology is playing a part in every sector of people’s lives. There are always positive and negative affects to everything, and new technologies are a prime example of this. People have always been interested in what the World’s oceans can provide, and people are using new technology to investigate these possibilities. However, technology can have a negative affect on different biodiversity in the ocean. Focusing specifically on the Atlantic Ocean,…

the fertilizer spurred cyanobacteria growth. Hot summers and other factors made matters worse” (Kowalski 34). As a result of pesticide entering into lakes and rivers farmers must reduce their use of pesticide. The main contaminant causing toxic algal blooms in Lake Erie is pesticide coming from farms. Lake Erie has become unhealthy as pesticide use from farms have increased due to runoff of nitrogen and…

marine environment. Sewage disposal is also harmful. All of the toxins that are in the sewage travel through ponds, lakes, rivers and end up in the ocean creating toxic algal blooms. These algal blooms are very harmful, if any animal makes contact with the blooms they are either contaminated or the die instantly. Harmful algal blooms have severely harmed human health, aquatic ecosystems and environments. All of the different categories of pollution are all relevant to each other, the ones…

areas with instances of water eutrophication. According to the NOAA, farmland runoff from the Mississippi river basin empties into the Gulf of Mexico, and contains high enough concentrations of fertilizer nutrient ions that massive algal blooms are…

A recent study proposed and led by researcher Dr. Peter Cook has established a connection between Domoic acid, a neurotoxin produced by Pseudonitsczhia algal blooms and spatial memory loss in Californian Sea Lions (Zalophus californianus). In one of the experiments conducted, similarities between within session errors and spatial tasking of sea lions and rodents’ were measured. Test subjects were given four locations to forage for food after initial feeding at the central location, and are later…

Lake Erie’s toxic algae blooms are becoming deadly, all of the local residents need our help. Everything started in the 1960’s in Cleveland, Ohio. Many factories/machinery at that time made lots of pollution that was dumped into the lake on purpose. All of this pollution gave Lake Erie many bad vibes, which led to the nicknames Lake On Fire or Dead Lake. Lake on Fire is due to the Lake catching fire many times. “As a result of these pollutants, Lake Erie contained increased levels of phosphorus…

affect the primary production of an ecosystem, namely light and nutrients, I learned that there can be harmful results if these factors are altered. If there is an increase in nutrients, which causes an increase in the production of diatoms, the algal bloom that can result effect not only the fish who directly eat the diatoms, but it can also have effects at a larger scale. Because the diatoms are at the bottom of the food chain, if there is a problem at that level, it can cause consequences…

Algae, a form of biomass, help lakes, but they do need the right environment with the correct pH and different light conditions in order to aid the lake’s health. Algae use sunlight to make food for themselves and give themselves energy through the process known as photosynthesis by using chlorophyll. They also absorbs carbon dioxide, turning it into energy, which would take place more in the nighttime when it’s dark. In this longer-term experiment, I will be evaluating the sun or lack of sun’s…

parts per million. Introducing additional phosphates into water results in a massive growth of algae, which are aquatic plants including many single-celled, free-floating plants. Excessive amounts of algae cloud the water in an effect called an algal bloom, which reduces the sunlight available to other plants and sometimes kills them. When the algae die, the bacteria that break them down use up dissolved oxygen in the water, depriving and sometimes suffocating other aquatic…

Ocean Pollution: A Manmade Crisis In modern society, people do not give a second thought to what is going on in the environment or the changes occurring around them. Many people live with the notion of “out of sight, out of mind” but how much longer can that kind of thinking go on before it is too late? Ocean pollution has been a problem since the Roman times. Which means it has been going on for roughly 2,000 years. 2,000 years of polluting the seas, endangering the marine life, and even…
