Oceanography As Viewed From Space Essays - Oceanography,
Oceanography As Viewed From Space Oceanography as Viewed from Space Introduction At first thought, studying the oceans from space seems to be a bizarre idea. Space observation helps oceanographers do research with manned and unmanned space systems. The space systems can be satellites and/or space shuttles that observe various features of the ocean such as sea-surface winds, sea-surface temperatures, waves, ocean currents, frontal regions, and sea color. Technological advances have greatly improved the ability of oceanographers to gather and use information that is received. Oceanography as viewed from space has and will become more and more valuable as we begin to understand more of the world's oceans. Projects Space oceanography uses a number of different sciences to research the oceans that include physics, geology, biology, chemistry, and engineering (Cracknell 13). This is evident in the projects that send satellites into space for observation of our oceans. In 1992, the Topex/Poseidon project was launched to observe the interaction between the ocean and the atmosphere (Cracknell 17). The Topex/Poseidon mission is to gather information about sea level heights and ocean currents (Cracknell 17). The Topex/Poseidon orbits above the earth at 840 miles and has a 10-day repeating cycle in which it takes pictures of all of the earth (Cracknell 17). Information about the how the sea level changes can tell scientists that there are changes in ocean currents and in climate patterns (Cracknell 25). This information is valuable to both oceanographers and meteorologists because it gives information about the phenomena, El Nino. Figure 1 is a picture of how the Topex/Poseidon works. Figure 1(NASA) The Topex/Poseidon receives information as to what it is supposed to do from a beacon on earth. The satellite then gathers the information it is supposed to gather and then sends it to the beacon on earth. The beacon on earth processes this information so that scientists can use it. As the Topex/Poseidon nears the end of observation new developments are being made to continue with similar work. Jason 1 is an observation satellite that will look at extending research about the interaction of oceans with the atmosphere, improving predictions about the climate, continue to monitor El Nino, and observe ocean eddies (Cracknell 26). These satellites are leading the way to a better understanding of our oceans as well as weather on planet earth. History Observations of oceanographic features with pictures were first realized with the invention of the camera (Pinet 181). Soon after the invention of the Camera, hot air balloons were used to take high altitude pictures of the land and sea, for mapping purposes (Pinet 181). In World War II, pilots took pictures of large areas of land that were used to develop strategies in the war (Pinet 181). At the beginning of the space age, just after World War II, rockets (although never in orbit) used movie cameras to photograph the surface (Pinet 182). The first manned shuttles took pictures of Earth and realized there were many observations of the oceans to be made (Pinet 182). Soon remote sensing came into action as satellites were sent into orbit (Pinet 182). Process of Remote Sensing Remote Sensing involves two types of instruments, passive and active (Gautier 58). Passive instruments detect natural energy that is reflected or emitted from the Sun (Gautier 59). Scientists use a variety of passive remote sensors such as a radiometer, imaging radiometer, and spectrometer. A radiometer measures the intensity of electromagnetic radiation in a band of wavelengths in the spectrum (Gautier 59). The spectrum is a measure of the visible, infrared (heat), and microwaves emitted from the Earth (Gautier 60). An imaging radiometer has the capability to scan an area and provide pixels of an area giving more detailed images of the surface than a radiometer (Gautier 60). A spectrometer detects, measures, and analyzes the wavelengths of the spectrum using prisms to separate the colors (Gautier 61). Active instruments provide electromagnetic radiation to observe an object (Gautier 69). Satellites that use active instruments send a pulse of energy towards the object being observed, then wait for the energy to be reflected (Gautier 69). This energy is then picked up as weaker or stronger in areas, which can define what features the satellite is looking at (Gautier 70). Some active instruments are radar, scatterometer, and

Next order mult. papers and PPT. they need to build on each other too Essay
Next order mult. papers and PPT. they need to build on each other too - Essay Example The customer has added to the complaint that after a period of three months the cylinder head had started to show leaks and he had to get repairs done. After a period of five months the engine had started showing problems that were repaired and by that time the warranty had expired so a new engine had to be bought. I have noticed similar complaints in the case of the 1997 as well as the 2000 models of Ford Expedition. In addition to the oil cylinder and the engine problems the one point that has been raised very aggressively by the customers is that the company has not been too helpful in paying the repairs for the losses. It has been mentioned by one of the customers that her expedition had been reporting errors in the gasket and she asked our organization for the repairs that was under warranty. But for unknown reasons our organization had been unable to pay for the losses and had not paid for the repairs either. All the complaints can be summarized by saying that there are problems in the case of the head gasket as well as the oil cylinder. The engine might be in need of being rechecked in a detailed manner so that the newer Expedition do not show such problems as these are the problems in the Expedition models that have become, sadly, well known among the people. The organizationââ¬â¢s reputation is the most important to me and the other clients. Any kind of issues that might be harmful to the companyââ¬â¢s reputation have to be dealt with in a strategic manner so the future clients can be made to trust the organization. The issues that we might face in the future, as I might say, need to be dealt with at this very point so that they are resolved at an earlier stage rather than being delayed. The customers are the main stake holders for the organization and we, at Ford Motors respect this relationship in the business. The customers need to be heard regarding their complaints so all the trust is regained in order that they
