Sargassum DOM optical properties tested for photodegradation rates and pH dependence from experiments conducted in outdoor tanks with Sargassum samples collected off the coast of Bermuda and in the Sargasso Sea in 2016

Abstract:

Sargassum DOM optical properties tested for photodegradation rates and pH dependence. Sargassum was collected during two sampling events in July and in late September/early October 2016. Sargassum samples were collected aboard the R/V Henry Stommel off the coast of Bermuda and R/V Hugh.R. Sharp in the Sargasso Sea. Outdoor exudation experiments were performed under natural (sunlight) conditions (n = 4) (data were published in Powers et al., 2019). After incubation experiments, Sargassum dissolved organic matter (DOM) was isolated by a solid phase extraction (SPE) technique. Sargassum SPE-DOM was primarily used for the irradiation and pH titration experiments. Optical properties were monitored during these experiments.
