Exploring a link between Atlantic coral mounds and Phanerozoic carbonate mudmounds: Insights from pore water fluorescent dissolved organic matter (FDOM), Pen Duick mounds, offshore Morocco

Sediment Pore Waters

“…Fluorescence spectroscopy has been applied to pore water DOM in a variety of environments including estuarine and marine sediments (Benamou et al, 1994;Burdige et al, 2004;Chen and Bada, 1989;Chen and Bada, 1994;Chen et al, 1993;Coble, 1996;Komada et al, 2004;Komada et al, 2002;Seretti et al, 1997;Sierra et al, 2001;Skoog et al, 1996), intertidal sand flats and subterranean estuaries (Kim et al, 2012;Lübben et al, 2009), mangrove and salt marsh sediments (Marchand et al, 2006;Otero et al, 2007), and deep-sea coral mounds (Larmagnat and Neuweiler, 2011). These studies examined properties of fluorescent DOM (FDOM) through the determination of fluorescence intensity at fixed excitation and emission wavelengths, emission spectra at a limited number of excitation wavelengths, synchronous scan spectra, or full three-dimensional excitation-emission matrix (EEM) spectra.…”
