Water quality will <br />be analyzed and related to these <br />types of metal sources along the <br />main stem of the upper Arkansas <br />River. <br />Several kinds of remote sensing <br /><lata will be used during the proj- <br />ect. The sensors used to collect the <br />data vary in spatial resolution, <br />spectral resolution,. and cost. <br />Obtaining data from a sensor on a <br />satellite platform is less expensive <br />tftan from an airborne platform, <br />but the spatial J;'eSolution is usually <br />poorer. Various sensors will be <br />used in the project. .Severalthat are . <br /> <br />likely to be used are outlined in the <br />"Sensor Types" table above. <br />This is an important project for <br />CGS. Hopefully it will further <br />future application of remote-sens- <br />ing technology in environmental <br />characterization both within and <br />outside of Colorado and help <br />answer some important questions, <br />such as: can hyperspectral remote <br />. sensing help in environmental <br />characterization of both mining <br />and natural sources of metals and <br />acidity to watersheds? What are <br />the geochemical controls on metal <br />solubility and mobility in the South <br />Fork and Lake Creek watersheds? <br />How is water quality in Twin <br />Lakes Reservoir and the Arkansas <br />River affected? How can current <br />sensors be improved to make <br />remote-sensing technology more <br />suitable and cost-effective- for this <br /> <br />Get RockTa'k by E-mail <br /> <br />To request a digital copy, e-moil cgspubs@slate.co.U5.
