英文摘要
Nutrient enrichment of coastal waters is a significant national and international problem requiring urgent action. Despite many studies and many millions of dollars in research funding we know virtually nothing about the relative importance of the major nitrogen cycling pathways, N-fixation and denitrification. Many hundred's of millions of dollars are likely to be spent over the next ten years on the management of nitrogen enrichment of Australia's coastal waters. This study will use a new method for directly measuring N-fixation to resolve uncertainty over the importance of N-fixation versus denitrification in coastal systems; information which is critical for the efficient allocation of management resources.
