Benthic-pelagic N-cycling under shifting redox conditions and hydro-dynamical forcing (B06)

B6旨在通过实验研究底部水的变化和O2、NO3-和NO2-的消耗对秘鲁海域沉积物中氮损失和再循环途径的影响。第二个主要目标是通过量化底栖营养物通量与上层营养物运输过程和南部冬季通量的结合，确定秘鲁海域底栖-上层营养物收支的自然变异性。以前的SFB 754研究是在秘鲁南部夏季进行的。B6将有力地补充我们对在不同时间尺度上控制秘鲁海域底栖海洋营养物清单的关键贡献过程和主要反馈的理解。

B6 aims to experimentally investigate the effects of bottom water variability and depletion of O2, NO3-, and NO2- on nitrogen loss and recycling pathways in the sediments off Peru. The second major aim is to determine the natural variability of the benthic-pelagic nutrient budget off Peru by quantifying benthic nutrient fluxes in combination with pelagic nutrient transport processes and fluxes in austral winter. Previous SFB 754 studies off Peru were carried out during austral summer. B6 will strongly complement our understanding of key contributing processes and major feedbacks controlling benthic pelagic nutrient inventories off Peru at different timescales.
