Title
Impact Removal Of Marine Suspended Sediment On Estimate Of Chlorophyll - A Pigment Concentration
Abstract
Determining precisely is hat portion of upwelling water leaving radiance attributed to chlorophyll-a pigment alone is it complex undertaking, The suspended sediment reflect more radiance than chlorophyll-a normally. The calculation of chlorophyll-a using maximum ratio of SeaWIFS band 2/5, band 315 and band 4/5 according to OC4 algorithm gets low accuracy on coastal zone, which is rich suspended sediment distribution impact. A improved approach is de,. eloped to remove the impact of suspended sediment and dissolved organism on chlorophyll-a pigment estimate. The SeaWIFS band 6 with spectrum 660-680 mum, on which the low reflectance of chlorophyll-a pigment is distributed, is applied to detect suspended sediment, the spectral curve model of different suspended sediment concentration is measured in situ and demonstrates that different suspended sediments have a prominent spectral curve between 550-750 mum and varied spectral curve slope, these curve model has been added to the chlorophyll-a concentration calculation algorithm. The correction evaluation of suspended sediment for chlorophyll-a calculation is made to assess the correction quality, the in situ samples of chlorophyll-a are compared with un-corrected chlorophyll-a map and corrected chlorophyll-a map, the results shows that suspended sediment the correction for chlorophyll-a has improved about 5% of accuracy of chlorophyll-a concentration.
