The optical characterization of chromophoric dissolved organic matter using wavelength distribution of absorption spectral slopes.
Steven Loiselle,Luca Bracchini,Arduino Massimo Dattilo,Maso Ricci,Antonio Tognazzi,Andrés Cózar,Claudio Rossi +6 more
TL;DR: In this article, the authors used a new approach to characterize the absorption characteristics of chromophoric dissolved organic matter (CDOM) in standard solutions and in several tropical lake ecosystems (Lakes Victoria, Lake Tanganyika, Laguna Ibera) in order to identify similarities between lakes and standard solutions as well as to show the wavelength intervals in which photodegradation modifies spectral slope.

Chemical and optical phototransformation of dissolved organic matter.
Steven Loiselle,Davide Vione,Claudio Minero,Valter Maurino,Antonio Tognazzi,Arduino Massimo Dattilo,Claudio Rossi,Luca Bracchini +7 more
TL;DR: The results show that the triplet states of chromophoric dissolved organic matter (CDOM) are potentially key players in CDOM photodegradation and that such transformations are strongly influenced by small differences inCDOM sources and sinks.

Variability in factors causing light attenuation in Lake Victoria
Steven Loiselle,Nicholas Azza,Andrés Cózar,Luca Bracchini,Antonio Tognazzi,Arduino Massimo Dattilo,Claudio Rossi +6 more
TL;DR: In this article, the major optical components controlling the attenuation of photosynthetic available radiation in nearshore areas of Lake Victoria (Uganda and Kenya) were examined and their impact compared.

The spatial distribution of optical properties in the ultraviolet and visible in an aquatic ecosystem.
Luca Bracchini,Steven Loiselle,Arduino Massimo Dattilo,Stefania Mazzuoli,Andrés Cózar,Andrés Cózar,Claudio Rossi +6 more
TL;DR: The methodology permitted a quantitative description of the interaction between solar radiation and aquatic ecosystems as well as a spatial classification of the dominating processes within the lake, including the determination of the role played by DOM loading and changing chemical propertiesWithin the lake optical environment.
