Conclusively, our research cruise information turns out to fall in general terms. However, there is factors that effect the results. One factor that influences the data results is El Nino. What is El Nino? El Nino is "A southward-flowing, nutrient-poor current of flowing, nutrient-poor current of warm water off the coast of western South America, caused by a breakdown of trade-wind circulation."(Oceanography: An Invitation). Specifically, El Nino influences seawater temperature, density, and oxygen in the water. First all, El Nino influences seawater temperature by causing seawater temperature to increase. For example, in fall of 2014 at a depth of 3 meters water temperature is 19.49 Celsius; however, in fall of 2015 the seawater increases to 21.27 Celsius, which is a 1.78 Celsius increase. The average atmospheric temperature for fall 2014 and fall 2015 is around 25 Celsius (based on personal calculations from various sites). Thus a clear evidence of how El Nino influences water temperature. Additionally, seawater temperature influences the density of the water. In general, the colder the seawater the greater the density and the warmer the seawater the less dense the seawater. Specifically, in the fall of 2014 the seawater density at a depth of 15 meters is 1024.98 g/cm3; however, in comparison to fall of 2015 the seawater temperature in Long Beach is 1023.4 g/cm3. El Nino also effects the oxygen in the seawater. Why? This due to the fact that warmer seawater is able to hold…

government does not pay attention to overfishing and doesn't put a limit on fishing. An example is the Canadian government, the Canadian Cod Fishery in the…

It all begins in Monterey Bay California, where author Johnathan Steinbeck and a close friend by the name of Ed Ricketts seek out boat and crew for a Marine Science expedition. Fishing out of Monterey bay is no strange occurrence, but Steinbeck’s and Ricketts voyage was quite different from all the other boating operations in the area. They were planning on sailing into the Sea of Cortez between the boarder of Mexico, and Baja California. This territory at the time was still being explored and…

depleted ocean fish population lost $164.2 million and realized just 2 percent of potential revenues because decades of overfishing.” They go on and explain how “this additional income could have been earned had these fish populations not been subject to years of overfishing that results in their current depleted condition.” Conservation and Management Act (MSA) with bipartisan requirements want to create science- based catch limits to end overfishing and replenish deplete fish populations. The…

traditions (Mathis et al., 2014). Mathis et al., concluded that Alaska fisheries are extremely vulnerable to the effects from OA in the region’s four seas that ring Alaska--the Chukchi, Beaufort, Bering, and Gulf of Alaska (See Appendix A, Image 1) (Mathis et al., 2014). Alaska’s fishing industry currently supports more than 100,000 jobs and generates over $5.8 billion in annual revenues while contributing to the balance of trade in the U.S. (Mathis, et al., 2014). Southeast Alaska was…

In the mid 1900s, the demand for protein-rich foods substantially increased. Salted and pickled herring were two dishes that greatly rose in popularity in these decades [4]. In Alaska, herring harvests netted profits up to $65 million for 140 million pounds of herring in only one year. Fisheries have broken the harvesting process down to a science by mapping the species’ migration patterns and timing their harvesting seasons to line up with the herrings’ breeding season. These methods help the…

Daniel the Giant Danio Introduction Daniel. What kind of name is that for a fish? A Great one. Oh well. I guess that's the story we're going with. I guess. Anyway, Daniel is a Great big fat Danio which is basically a type of fish that's pretty huge. 5 inches. Big Whoop. Eh, I kinda agree that's not so BIG. Ya know what? I'm done for the Intro. I'll let Kirby take over the next gosh darn part.Who says I'm writing the next part? Fine then. I'll do it. Daniel was in his tank at the pet…

I am writing this letter today to inform you about the big Asian carp crisis. The Asian Carp are an invasive species that came from china. They were brought over to clean fish ponds and escaped due to the flooding of the fish ponds. They are now out there in the lakes reproducing in large amounts and threaten to take over the great lakes. According to “Carp Diem: A Fishy Tale” by CBC, 2013, Asian Carps are reproducing in large amounts and tend to outcompete native species. The Asian carps are…

Change is inevitable, and it is a wave in a stormy ocean that can either bring a person down or lift them up. In Toni Morrison 's The Bluest Eye, the Breedlove family is dragged down by the constant reminder that they are not a beautiful family, and how they never will be. The standards of beauty corrupt the Breedlove family, causing Pauline to become insecure and take her insecurities out on her family; and Pecola 's friendships suffer, as well as her sanity from her many hardships.…

Chinook salmon (Oncorhynchus tshawytscha) is an ecologically and economically valuable species that is found along the Pacific coastlines of Asia and North America. Unfortunately, many Chinook populations have been steadily declining during the last century, primarily due to a variety of human activities. These threats include hydroelectric dams, chemical pollution from planes (Dietrich, et al., 2012), and sound pollution from industry (Halvorsen et al., 2012). North American governments and…
