Ocean Depth Probe - Essay ExampleElectromagneticCompatibility is the dexterity of electrical and electronic systems, equipments, and devices to operate in their intended electromagnetic environment within a delimitate margin of safety, and at design trains or performance, without suffering or ca apply unacceptable degradation as a result of electromagnetic interference (Electronic Project Design 2009). So, various aspects of the Ocean including the natural domain magnetic field at certain depth and the unnatural magnetic fields caused due to pitying being for their different installment of instruments have to be sorted out so that no interferences turn over at the time of maritime depth probe.All types of equipments and systems must be designed to meet electromagnetic compatibility (EMC) specifications. To achieve this aim, special design techniques are necessary. Their effective use in practical applications depends on the instinct of the underlying physical principles. EMC problems involve complex electromagnetic interactions and hence skunk only be tackled efficaciously by a combination of experimental and numerical tools (Christopoulos 1992, pp. 239-247)At the time of investigation of the depth of ocean, using the different techniques to explore the ocean for various purposes the movement of the sound wave in the different level of water is different, depending upon the nature of the water quality and various objects and animal present at particular level. Thigpen et. al (1985) have find out that in marine seismic exploration, an acoustic source disposed beneath the water surface generates a signal which is reflected from layers beneath the ocean floor and received by hydroph bingles committed to a remote recording unit. The further investigation explains that the received reflected signal provides information about the submarine characteristics of the earth (Thigpen, B B et al. 1985). This production of sound may interfere if not used the righ t way for the investigation.In an experimental report find out by Thigpen et. al. (1985) shows that conventional acoustic sources used in marine exploration consist of an array of many air guns or water guns fired simultaneously at pre-selected time intervals. Explaining the effects by this experiment they say the shape of the acoustic wave or jot of the array is dependent upon the depth at which the array is fired and on the synchronization of the lighting instant among all the guns in the array. They find out some contrast results with word of caution that if one of the two parameters or both are not substantially the same for all guns the seismic signature will be less than optimum and if the depths of the guns are different, the firing instant of each gun can be changed by fractions of a millisecond so that the resulting acoustic wave front is at level best amplitude and strength. JAMSTEC (2007) has provided various techniques to standard the depth of ocean and to find out d ifferent aspects of benefit of ocean probe as followsSensors to Investigate the Ocean at Different Depths With the use of CTD (Conductivity (salinity), temperature, depth), an observational instrument to measure the conductivity (salinity), temperature and underwater pressure (depth) of the ocean, electrically, with its deployment in the ocean connected by cable to observe a vertical profile
