- Abstract:
- Photochemical breakdown of chromophoric dissolved organic matter (CDOM), the light absorbing fraction of dissolved organic matter, has been shown to yield a number of biologically available compounds in aquatic environments, including phosphate and ammonium. We propose to study the photoproduction of ammonium and phosphate from CDOM in the oligotrophic Cyprus Gyre employing nanomolar nutrient analysis techniques. In addition to in situ experiments we aim to investigate phosphate photoproduction under controlled conditions at Newcastle University, in particular the wavelength dependence of the processes involved. We hope to quantify photoproduction rates for the two nutrients and assess the role of ammonium and phosphate photoproduction in the marine environment and the oligotrophic Cyprus Gyre in particular.
