more-inExtremely low oxygen levels already occupy about 10 per cent of the world’s ocean areaPANAJI: Globally renowned experts will deliberate on decreasing oxygen levels in oceans at an international symposium here beginning Saturday. Experts attending the symposium would aim to address what factors are affecting the rates of marine nitrification (ammonium oxidation and nitrite oxidation) and denitrification so they can assess the role of microbial processes involved in nutrient cycles in the face of falling oxygen levels. The scientific community is aware of the fact that extremely low oxygen levels in the Eastern Tropical North Pacific, the Eastern Tropical South Pacific, and theArabian Sea already occupy about 10 per cent of the world’s oceans area. Declining oxygen concentrations lead to a reduction in rates of aerobic respiration and increase in respiration of oxidised nitrogen. It will provide a platform for cooperation among the attending participants across the globe to advance a more focused and effective research on ocean de-oxygenation.
