Fluorescent dissolved organic matter production via microbial respiration: A comparison between the equatorial Atlantic Ocean and the subantarctic zone of the South Atlantic Ocean
IV Congress of Marine Sciences, 11-13 June 2014, Las Palmas de Gran Canaria.-- 1 page The distribution of humic-like fluorescent dissolved organic matter (FDOM) at two different Ex/Em wavelengths, 340/440 nm and 320/410 nm, were obtained for both the equatorial Atlantic Ocean and the subantarctic zon...
