The Gulf of Mexico Dead Zone The gulf of Mexico’s dead zone is only getting worse doing a great deal of damage to the U.S. economy. The issue in the Gulf of Mexico is the dead zone that has started occurring since 1972 and is only increasing in size. The Gulf of Mexico supplies the U.S. with 72% of their income shrimp 66% of oysters and 16% of fish (Philpott‚ 2013). If the dead zone does not decrease in size fisherman and costal workers will be largely impacted

Are Dinoflagellates?”). Uniquely‚ dinoflagellates have two flagella. One flagellum is around the cell‚ and the other directed to the back. They contain chlorophyll a and c‚ as well as other carotenoid and xanthophyll pigments. When dinoflagellates bloom‚ or overpopulate‚ they tend to change the water to a reddish brown color. Dinoflagellata are sometimes called Pyrrhophyta‚ meaning "fire plants". This is because some species are capable of bioluminescence‚ in which chemicals made by the organism produce

5.4 Eutrophication 5.4.1 Outline the processes of eutrophication. Eutrophication is the addition of excess nutrients to a water system‚ which leads to the growth and subsequent death of algae‚ which reduces the dissolved oxygen available for other aquatic organisms. The main stages or steps of eutrophication are (in order): Nutrients wash into a river or stream. Algae grow quickly in response to the added nutrients. The algae block sunlight to aquatic plants‚ so photosynthesis slows‚ and
