Abstract
Penetration of ultraviolet radiation (UVR) in stream ecosystems is determined by the concentration and optical properties of suspended sediment and dissolved organic carbon (DOC). This study documents the base-flow optical environment of 37 first- and second-order tributaries distributed throughout the Lehigh River watershed, eastern Pennsylvania, over a four year period. We measured a large range of attenuation coefficients (Kd380: 0.68 – 151.1 m−1, Kd320: 0.95 – 316.2 m−1) and 1 % transmission depths (2 cm – 147 cm)...
