Neospirifer: Marine Autonomy

He noticed that the rocks at the top of the section had a very high percentage of fossils of living mollusc species. Those at the bottom of the section had very few living forms. He deduced that this difference was because of the extinction of older forms and the evolution of living forms during the time that the rocks were being deposited. He divided the Tertiary rocks into three sub-ages: the Pliocene, the Miocene, and the Eocene. 90% of the fossil molluscs in Pliocene rocks were living today. In the Miocene rocks, only 18% of the molluscs were of living species, and in Eocene rocks, only 9.5%.” (Polly et al.,

The guarantee of work, an excellent benefit that offers to employees and the quality of training program at the Seafarers Harry Lundeberg School of Seamanship are the reasons why I want to be a Merchant Mariner. A Merchant Mariner career provide an established job and the outstanding of income to the seamen moreover, it also offers a great benefit to cover their family. With the prospect of jobs demand a merchant mariner has opportunities for growth in the marine jobs and it has high level demand to serve the maritime shipping industry, particularly in the private sector like a cruise ship and cargo industry that operate around the world. These private sector depend on the Merchant Mariners to perform preventative maintenance on equipment and delivery cargo on time. Base on the world consumer and the US economy depend on cargo ship and Cruise ships to support gross domestic product.

While the author of the article believes that Brachiosaurus were aquatic animals, the professor disagrees with this statement. The professor points out that in spite of the fact that some species of dinosaur would spend a great deal of time in water, there was no possible that Brachiosaurus were aquatic ones. To strengthen her point, the professor provides sufficient evidence respectively to the points made in the article.

b) Connell showed that the realized niche of the barnacle semibalanus was the same as its fundamental niche by clearing the upper tidal reach of Cthamalus so

The United States has constantly been developing and advancing their military branches, strategies, and special forces. There are five branches of the military: Army, Navy, Marine Corps, United States Coast Guard, and the Air Force. The first branch of the military to form was the Army in June 1775. The Army formed after the American Revolutionary War. Its purpose was to coordinate attacks on Great Britain’s Military. The next branch of the military to form was the United States Navy. The Navy was formed in October 1775. The Navy had been assigned missions to ambush, prevent, and hinder British aquatic or naval operations. After the Navy came the United States Marine Corps. The Marine Corps was a special tactical team that was able to fight at sea and on shore. 15 years later came the United States coast guard. The United States Coast Guard enforced maritime safety generally to enforce federal tariff and trade. The next branch didn't form for many years later until 1947. The Air Force was created to defend the nation through the control air and space. As you can see the United States has vastly developed their military divisions. Each division has

Summary: The Man Who Mistook His Wife for a Hat" by Oliver Sacks is a collection of cases and studies of patients with bizarre neurological disorders. The neurological disorders discussed include examples of deficits, excesses, reminiscence, and the "world of the simple". Neurologist Oliver Sacks discusses the stories of his patients and patients of other neurologists while appealing to logos, ethos, and pathos. Throughout the text there is a fair balance between logos, ethos, and pathos.

President Obama established a national marine memorial off the coast of New England. The new memorial, which is about the size of Connecticut, houses geological and ecological treasures. Under the surface of this protected ocean rest canyons and extinct volcanoes. Rare fish, coral, whales, and turtles count themselves among the animals that live in the memorial. Critics cite the possible harm the memorial will cause to the fishing industry.

Out of my time in the Marine Corps I have come to notice that my though process has become almost autonomous. Many people know the Marine Corps has a strict command structure however, we operate using a very decentralized system. I would have to say that due to this my strongest characteristic would be Intellectual autonomy which is defined as willingness and ability to think for oneself. The ability to make decisions for my self and my Marines not only gives a more direct link and quicker reaction time to situations but it also allows my marines to grow confidence in the decisions I make. On the Battlefield my Marines and I are faced with taking a piece of key terrain (KT105) that could turn the tide of the fight. There are a number of enemy combatants between my squad and KT105. Although most of the enemy combatants are untrained they have a number of small arms and one machine gun nest posted 100m

All vessels and ports are vulnerable to bombings or WMD attacks. Because of their locations and volume of business ports, cruise ship and ferry terminals are challenging to protect from security threats. They are usually in areas that consist of a lot of people, which makes them a target for terrorism. Additionally, often times these areas also have liquefied natural gas facilities which will make them more vulnerable and attract terrorists. The bombing of the Navy Destroyer, the USS Cole illustrates that any vessel can be attacked. Terrorists utilized a small boat to serve as an improvised explosive device as they navigated it into the ship while it was refueling.

From 1974 to the present, two separate spacecraft have completed journeys to Mercury: Mariner 10 and MESSENGER. The objective was and is the same for both, that objective being to get pictures of Mercury from several angles, so scientists at NASA have multiple points of reference. Mariner 10 attempted this, to little avail, and so MESSENGER was brought on to do the job.

The Marine Corp is full of standards and rules that must be followed at all times. When on duty we are given our 11 general orders that, if not followed closely, will cause death and possibly injuries to not only ourselves but others as well. When in uniform we are to be neat and presentable no matter what as we are representing something more than ourselves. We are to be shaved every day. We are to get a haircut every Sunday. And we are to be clean and honest. Doing these things is just one more way we set ourselves aside from all others. When we’re out of uniform, why should the rules be any different? Well, they’re not. We as Marines are expected to be just as professional in civilian attire as we are when we are in our Dress Blues. But

The author and his colleagues chose to focus on 375 million year old rocks in their search for fossils because amphibians that look dissimilar to fish were discovered in 365 million year old rocks, while fish without amphibian characteristics were discovered in 385 million year old rocks. Thus, it is possible that the evolutionary intermediary, or the “missing link” between fish and amphibians, would be discovered in 375 million year old rocks, between the two time periods. The rocks examined were sedimentary in composition, as the gradual and relatively gentle formation of sedimentary rock under conditions of mild pressure and low heat are conducive to the fossilization of animal remains. Sedimentary rock is also often formed in rivers and seas, where animals are likely to live. This site provides a resource that describes means by which fossils are formed and how the fossil record may be interpreted, and shows some examples of fossils demonstrating evolution through geological periods: http://www.fossilmuseum.net/fossilrecord.htm. In 2004, Shubin and his colleagues were looking for fossils on Ellesmere Island, in northern Canada. This location was chosen because of its lack of human development, as well as of obstructing natural formations and life forms such as trees, which

A marine is an incredibly proud soldier of the sea. That being the starting need for the corps. Being a marine is a mindset and a way of life. Pride of the title that was made into what it is today from those before them, that is what gives confidence to marines. To treasure one another and do their up most to protect and build eachother is the comradarie and power of the marine corps. When exposed to danger or in war the will to fight and protect eachother shows that every marine is a rifleman. In 1950 a rifle platoon was formed from an artillery gun crew, cooks, bakers, and clerks lead by a lieutenant from motor transport; they functioned proficiently several times. Past events such as the Frozen chosin demostrate the marine

Many bivalves are infauna organisms where they burry deeply more than 30 cm and live as permanent burrows where they will move deeper as they grow larger (Gosling, 2003). Although most of them are burrowing organisms, there is also group that live permanently attached on the surface or known as epifauna and epibenthos is groups that live in association with seafloor but also swim temporarily above it (Huber, 2013). Bivalve possess two halves of the mantle that are fused around the edges, with openings anteriorly for the foot and posteriorly for the exhalant opening where the water will expelled from the pallial cavity (Bunje, 2001) as shown in Figure 2.1. In addition, within this posteriorly is also located the inhalant opening that carried
