Oceanography As Viewed From Space Essay

1235 words - 5 pages

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...

Bars are created off shore at a location where currents and waves have caused a buildup of sandy deposits that look like “hills” or ridges underwater of sand and sediment. A similar feature to a sand bar is a spit, a spit is a linear ridge of sediment that extends in the direction of longshore drift from land into deeper water near the mouth of a bay.

Hydrogen gas, being the lightest, will rise to the upper troposphere and slowly bleed into space through Atmospheric escape.” (Cote 2013

Sea ice also provides hunting and breeding grounds for marine mammals and birds (Carscallen and Ramanuk 2012). Polar organisms have a strong dependence on sea ice, and the declining sea ice cover will result in major changes to the energy-flow pathways
