Turbidity Levels : Causes Of Algal Growth

The purpose of this is experiment is to more closely understand the effects of nutrient enrichment on samples of water from Encanto Park Lake and the Rio Salado River. More specifically the concentration of nitrogen, phosphorus, and nitrogen and phosphorus together were altered and the effects this had upon algal growth were then observed. The results indicated that an increase in nitrogen concentration showed minimal

Phosphorus, “...the primary algae-feeding nutrient in Lake Erie, and contributed to the largest algae bloom in history last year” (McCarty, para. 3), is a key factor in how

Answer = The graph shows the fish population increases in due to more dissolved oxygen that is found in the body of water.

Since the algae population decreases, so does the algae bloom, which sink to the bottom and decompose to create oxygen many underwater animals need. Some blooms also produce toxins, which can harm or kill the fish, harm animals that drink the water, and cause problems for humans as well. With a decrease in algae blooms, plants and animals would no longer have a steady population. They would end up

Algae blooms have been an issue in the Chesapeake Bay, especially in the Baltimore Inner Harbor. Algae is a natural and critical part of the ecosystem, however in large doses it is harmful to the plants and organisms within the ecosystem. Algae blooms can block out sunlight and kill other plants in the water. Algae depends on various factors such as water, nutrients and carbon dioxide to grow. Eutrophication of the Inner Harbor has lead to algae blooms that have caused large fish kills in the past. When there is an over abundance of certain chemical nutrients eutrophication can occur. Runoff from land and farms is the main cause of excess nutrients into the water. The most common nutrients that are related to algae outbreaks are nitrate nitrogen and phosphate. In addition, a lack of dissolved oxygen can also be an indicator for the process of eutrophication and risk of an algae outbreak. A particular type of algae commonly found in Maryland is known as Prorocentrum minimum. Prorocentrum tends to cause “mahogany tides” causing water to be brown and have an odor. There has been a campaign launched by the Healthy Harbor

This article, posted by Kelsy Solway, on “CBC News”. It was published on July 8 2015 regarding the algae growth in Jackfish Lake. The article title is “Yellowknife dump runoff may be causing Jackfish Lake algae blooms” and can be access here. Additional analysis and summaries can be read below.

Results: After recording the data, we found a total of 10 different types of microorganisms in Winthrop wetlands (figure 1). In the lake, we found a total of 13 different types of microorganisms (figure 1). Since we found more organisms in the lake, we did a chi-squared test to see if the difference was statistically significant. The value we got after our calculation was 0.53 which is not statistically

The snow crab population is also increasing (Frank et al., 2005; Scheffer et al., 2005). This increase has led to the decrease in the large-bodied zooplankton species (>2 mm) because this is what the shrimp and crab populations prefer to feed off of (Frank et al., 2005; Scheffer et al., 2005). Now that the zooplankton abundance isn’t as high, the phytoplankton population has increased, which is due to the reduced pressure being put on them by the zooplankton (Frank et al., 2005; Scheffer et al., 2005). Lastly, the concentration of nitrate is lower, which suggests the phytoplankton populations are depleting it more strongly (Frank et al., 2005; Scheffer et al., 2005). These changes in the ecosystem can be quite harmful and can lead to breakouts of disease in the lower trophic levels because the populations become so dense that they are more prone to catching a disease (Jackson et al., 2001).

In this paper I will examine multiple perspectives in an attempt to understand the recent eutrophication of the Chesapeake Bay. Our textbook, Cambell Biology defines eutrophication as a process in which nutrients, usually phosphorus and nitrogen, are unusually present in a body of water, leading to algae blooms and accelerated growth. Anoxia is a condition in which areas of water are severely depleted of dissolved oxygen.

The purpose of this experiment is to understand the effects of nutrient enrichment and eutrophication, using samples of water from Rio Salado and Encanto Park. The samples will contain different concentration levels of nitrogen, phosphorous and nitrogen and phosphorous combined and the impact it has on algae growth. The results recorded showed that the nitrogen concentration levels had a little change, phosphorous levels had a higher change and phosphorous and nitrogen combined had a significantly higher change, resulting in higher algae growth. The results showed that phosphorous indeed is a limiting nutrient in algae growth, but to achieve the highest growth rate, both nitrogen and phosphorous need to be combined.

Did you know that algae blooms can form from pollution? They can. If citizens do not put a stop to pollution more algae will form. First of all, citizens need to put a stop to pollution because algae blooms die and release a chemical called phosphate. Phosphate causes more algae to form. Did you know that only one bloom has covered 800 miles of Lake Erie? That is only one bloom! Imagine

In Lake Erie, there is out-of-control algae growth that created dead zones. The problem has become critical in the western Lake because of harmful chemicals. Contaminants in fish certainly are causing health problems. At present, the solution is to make

Nitrogen in the lake is detected under the forms of Ammoniacal Nitrogen, Nitrate, and Nitrite. These three types of Nitrogen formed a parameter named Dissolved Inorganic Nitrogen (DIN). This factor DIN couples with the organic form of Nitrogen to define Total Nitrogen (TN). Total Nitrogen and Total Phosphorus are two of the most important micronutrient components for algal development and hence very important parameters to be used for predicting scenarios of algae bloom occurrence and

A few different factors that affect bacterial growth are the availability of resources and nutrients, temperature and pH. (Act For Libraries) stated in the above paragraph, once the resources and nutrients are

In addition, Some Vallisneria leaves changed colour from green to yellow-brownish as shown in figure 8. Plant nutrients, nitrate and phosphate supported production of chlorophyll, increasing rate of photosynthesis. However, excess of these nutrients reduced amount of chlorophyll and photosynthesis stopped. Green Algae formed
