Atlantic And Southern Gulf Of America

A Review of “The Devil and Deep Blue Sea” by Linda Pannozzo Introduction In her book The Devil and the Deep Blue Sea: An Investigation into the Scapegoating of Canada’s Grey Seal, Linda Pannozzo accomplishes few important things: she makes a compelling argument for the senseless killing of grey seal; she provides an analytic framework for the reasons of the decline of cod fish; and she provides a wealth of information on the politic behind scapegoating of Canada’s grey seal. Pannozzo presents The Devil and Deep Blue Sea in a clear and unbiased matter, but its presentation is by no mean elementary. Pannozzo’s book is meticulously researched, thus providing us with both quantitative and statistical account surrounding seal ways of life, their diet, history and other necessary aspects of marine life ecosystem. Book Summary

In this week’s chapter The Atlantic World which introduces the history from prehistory through 1566, there were two themes that stand out for me which are: The Big “C”s, Conquest, Commerce, Colonization, & Conversion and Race. The history resembles on the European expansion and the discovery of the Americas by Christopher Columbus. Christopher Columbus was the first person to discover the American continent. The New World was another name given to America. The American territory differed in social, economically and politically. America was divided by three societies: Aztecs, Mayan and Incan which belonged to urban societies. Colonization was a breakthrough for both continents. They adaptation was about to begin, there were new things that one continent had

The study of the Atlantic as an interwoven community is a relatively new theory. Historians are beginning to see Atlantic History as “a sudden and harsh encounter between two old worlds that transformed both and integrated them into a single New World” , and not just separate entities with detached pasts. Atlantic History: Concept and Contours by Bernard Bailyn lays the framework for what Atlantic History is and how it should be studied. Bailyn states that the reasoning behind writing the book is that previous historians focus too much on the imperial history of the Atlantic world, when in fact the colonized areas had just as much of an effect on European powers as Europe had on their colonies. In this concise two part book, Bailyn’s main argument is that the concept of Atlantic History was inevitable because it is impossible to look at any major event of this time period without seeing its effects ripple throughout the entire Atlantic world.

Crayfish, Orconectes propinquus, are ectotherms that do not generate internal heat and rely on external temperatures to determine their body temperature. The crayfish we tested were found in Medway Creek and therefore undergo considerable temperature changes throughout the year. Since these crayfish are able to adapt to various temperatures allowing them to live in numerous places, their survival rate would be higher than many other organisms.

As it stands today the U.S. coast of the Gulf of Mexico is losing more and more land; the amount of land lost each year may seem relatively small to the average person, but to scientists who understand the unprecedented rate at which this is happening, there is reason to be alarmed. On the U.S. coast of the Gulf of Mexico there are more reasons for the rising sea level than simply global warming and melting ice sheets or ice caps. In the Mississippi delta, for example, the oil industry is taking so much fluid (oil) out of the ground that the land is sinking and compacting further. There is also a decrease in the amount of sediment reaching the delta due to many man-made structures, such as levees, drudging, dikes, and

This article presents the impact of low oxygen waters on Chesapeake Bay Zoo-plankton. Anoxia (oxygen deficiency) reduces the cope-pod abundances in Chesapeake's bottom waters, and disrupts the cope-pods inhabits towards the bottom and their migration to the surface. Also, cope-pods will have limited survival ability in low oxygen conditions in bottom waters. Results show the number of cope-pods surviving for 24 hours were significantly lower in water containing smaller milligrams of oxygen liter. Some will have a greater chance of survival because of their low metabolism that requires smaller oxygen. Low oxygen reduces the filtration rate of zoo-plankton and the filtration rate of the fresh water. Decreased filtration reduces metabolic rate in low-oxygen conditions, generally occur in the mesohaline part in summer. Low oxygen-levels may cut phyto-plankton and Cope pod's production. Lower oxygen concentration prevents hatching and the growth of eggs, which eggs could survive a few days if temperatures are cold and as the eggs sink to the bottom.

* 20. Only a very wealthy man could afford the capital to invest in the land, machinery, and slaves needed to establish a sugar plantation. West Indian planters were very wealthy and translated their wealth into political power, controlling the colonial assemblies and even gaining a number of seats in the British Parliament.

In the beginning, America consisted of 13 colonies that were owned by the British.  After we had won our independence in 1776, we had bigger aspirations than just the 13 colonies.  The goal was to make America span from coast to coast, spreading democracy, capitalism, and American ideals across the now country.  This was rooted in the belief of Manifest Destiny.  This was the belief that America should span from coast to coast because we were the best.  Our first major land deal to further this goal was the Louisiana Purchase.  In exchange for 15 million dollars, (or about 233 million adjusted for inflation), America would receive a large portion of the Americas from France.  This purchase includes land from modern day states such as Louisiana, Oklahoma, Kansas, North and South Dakota, Arkansas, Iowa, Missouri, Nebraska, Minnesota, Northern Texas,

The Atlantic Ocean. It is one of the five oceans in the world. It is home to many fish and other creatures. It is one of the five oceans that actually intrigue me. My questions were, How big is the ocean itself, what life lives here, and the trade routes of this ocean.

Today’s eastern oysters range from 3 to 5 inches in length, sometimes as much as 8 inches, although the oysters present during the colonization of the New World were documented to grow much larger (“Oyster History”). Oysters have many great characteristics in regard to their utility for humans as well as wildlife. The build ups of oyster bars, reefs, and beds provide habitat for many aquatic lifeforms and the filtration capabilities they possess is quite remarkable; as filter feeders, oysters feed on phytoplankton and small organisms while removing nutrients from the waters the inhabit, leaving them clear and pristine; just one oyster can filter more than 50 gallons in a day (“Oyster History”). Alas, it was a palatable constitution that made the eastern oyster so popular, creating an extensive economy based on its harvest. Unfortunately, this considerable popularity would ultimately bring the oyster’s

Although the Easter Shore of Maryland is most well known for their shellfish, the abundance of shellfish barely scratches the surface of the marine life found in the Chesapeake Bay. From the shallows of the Bay to the bottom in one hundred feet of water, the life found in the Bay varies drastically. The different conditions foster an assortment of fish such as permanent residents, migrants, and occasional visitors. It is home to mature fish and is also an important nursery ground for millions of ocean fish (Blair and Ansel 111). About two hundred and two species have been recorded as permanent residents of the Chesapeake and there are four classes of migratory fish (“Chesapeake Wildlife”). Species such as shad, alewife, and striped bass leave the marine environment to spawn in fresh water. In the summer, hardhead, spot, and menhaden reside in the Bay. Bluefish are a common migrant found in the

The Gulf Stream is a warm ocean current that originates at the tip of Florida and travels along the coast of the eastern most United States before crossing through the Atlantic Ocean. This powerful current has a strong northward accelerating current that at a point ends up slitting the direction of the stream into two: a northern stream that crosses to northern Europe and a southern stream that circulates off West Africa. Due to these properties the Gulf Stream has a major affect on the western coast of Europe and the eastern coast of North America.

The dead zone in the Gulf of Mexico is a human problem, like most other disasters. What this means is that once the place thrived and was ecologically balanced, but we tipped the balance slightly and wrecked havoc upon the environment. It has been noted to occur since the 1950’s and is ongoing. The reason that this dead zone occurs is because of a phenomenon known as eutrophication. Eutrophication is when there is an excessive amount of nutrients in a body of water and it causes an abundance of plants to grow. In this case the nearby farms had been using nitrogen in their fertilizers. The nitrogen got carried into the ocean through rain and other forms of

Each summer, semitropical fish appear in New England salt ponds. They are carried northward by the Gulf Stream. The Gulf Stream is a warm ocean current. It flows like a river through the cold Atlantic. It originates in the Caribbean. It winds through the Florida straits. It meanders northward along the eastern coast of the United States. Off the shore of Cape Hatteras, North Carolina, the Gulfstream and its warming influence farther from the coast. Semitropical fish are swept into the Gulf Stream from their breeding ground. The breeding ground is south of Cape Hatteras. The fish are carried northward. The strong current carries them. The current is often 20 degrees warmer than adjacent waters. Some of these fish are trapped in eddies. Eddies

If the temperature is optimum (14-16 o C), red abalone larvae hatch about one day after fertilization, develop into a morphologically mature veliger larvae after three days and are capable of metamorphosis after about seven days. Red abalone settlement and metamorphosis are by compounds released from coralline algae, which the young abalones graze upon. Within 2 months, the larvae develop into small sized adults while by the age of 1 year, an abalone reaches about 25 mm long, and within 4 years it reaches sexual
