The Impact of Trawling on Nitrogen Removal through Sediment Denitrification in Western Moreton Bay

拖网捕捞对西摩顿湾沉积物反硝化除氮的影响沿海水域的营养物富集是一个需要采取紧急行动的全国性问题。沉积物反硝化是少数能够抵消富营养化过程的自然过程之一。虽然拖网捕捞在澳大利亚沿海水域进行，但对沉积物反硝化和沿海系统氮收支的影响从未被考虑过。在接下来的十年里，可能会花费数亿美元用于管理澳大利亚沿海水域的氮富集。本研究将量化拖网捕捞对沉积物反硝化的影响；对有效分配管理资源至关重要的信息。

The Impact of Trawling on Nitrogen Removal through Sediment Denitrification in Western Moreton Bay. Nutrient enrichment of coastal waters is a national problem requiring urgent action. Sediment denitrification is one of the few natural processes capable of counteracting the process of eutrophication. Although trawling is undertaken in coastal water bodies around Australia the impact on sediment denitrification and the nitrogen budgets of coastal systems has never been considered. 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 quantify the impact of trawling on sediment denitrification; information which is critical for the efficient allocation of management resources.
