Effects of Depth and Sediment Concentration on the Penetration of Photosynthetically Active Radiation in Water IntroductionThe purpose of this study plan is to measure the effects of light on sedimentary particles in water This study plan will include information pertaining to equipment procedures and analysis This plan will also discuss problems that could arise during the sampling ObjectivesThe objective of this study is to observe whether sedimentary accumulation at various depths will effect the penetration of light energy One reason for monitoring light penetration is to determine if sufficient energy is available for photosynthesis This energy is effected by the amount of sedimentation that is suspended in the water In order to ensure the datas scientific validity this study needs to include the main principles These include selecting a control a control will be the measurement that all other data is compared to Second the selection of the sample sites must be non-bias and random This ensures that the experiments are not predictable or foreseeable Finally the experiments must be described in great detail so that they can be replicated at a later date LiteratureEnergy is distributed throughout the worlds oceans in several usable forms The heat transmitted during absorption is responsible for ocean waves temperature and currents Light penetration in water will measure in units of quanta This measurement refers to the amount of sunlight that penetrates the water at various depths The light energy is absorbed and scattered by suspended particles dissolved substances and the water itself USGS Other factors include attenuation coefficient rate at which light decreases with depth This means that each site studied may have a different attenuation coefficient An example of a high coefficient would indicate a rapid decrease in light penetration therefore high sedimentation Another factor to be aware of is the color of the water Color can effect the light penetration and intensity Also the turbidity which is a measure of
