This study aimed to determine phosphorus (P) concentration using reflectance spectra of grass and soils in the Lake Okeechobee drainage basins, Florida. A total of 150 grass samples and 150 soil samples were collected from the three sites in the Lake Okeechobee drainage basins. The reflectance spectra of both fresh and dried samples for grass and soil were measured using UV, VIS, and NIR spectr...

Water quality estimation in fresh and marine water systems with in situ above-water spectroscopy requires measurement of the volume reflectance (rhov) of water bodies. However, the above-water radiometric measurements include surface reflection (Lr) as a significant component along with volume reflection. The Lr carries no information on water quality, and hence it is considered as a major sour...

Acid-saline sediments in shallow-lake environments southwestern Australia host complex mineralogical suites representing long-term weathering and modern extreme acid-saline chemistry. It is not known whether large-scale reflectance spectroscopy datasets from watersheds across the Yilgarn Craton show regional variability. This study assesses over 2500 spectra of shallow subsurface by using autom...
