In order to be able to invert optical remote sensing data. it is necessary to understand the absorption. scattering and attenuation spectra. In this paper we present a study of the vertical distribution and spectra of the inherent optical properties by the particulate and dissolved materials in the Gulf of California. https://mysocialfeeder.com/story4381548/investigation-of-furrow-formation-by-rotary-tillage-tools-with-an-active-drive
