Critical flux paths influencing ecological processes in an urban estuary. This study will focus on the roles of benthic algae, denitrification and consumers on nutrient fluxes and planktonic production in the Swan River estuary, Western Australia. A 5-year research program of measurements and numerical modelling has identified these processes as poorly quantified, critical to the estuary trophic status, and essential data in order to accurately predict potential impacts of remediation strategies. We will validate the impacts of denitrification through in situ measurements, review data on higher order consumers, and use this information in a numerical model to understand the interactions of biogeochemical fluxes, plant, animal and microbial communities, and transport processes in the estuary.

影响城市河口生态过程的临界通量路径。本研究将着重于底栖藻类，反硝化作用和消费者的营养盐通量和浮游生产在天鹅河河口，西澳大利亚州的作用。一项为期5年的测量和数值模拟研究计划已确定这些过程量化不佳，关键的河口营养状况，和必要的数据，以准确地预测潜在的影响补救策略。我们将通过原位测量验证反硝化作用的影响，审查高阶消费者的数据，并在数值模型中使用这些信息来了解河口的生态地球化学通量，植物，动物和微生物群落以及运输过程的相互作用。
