We will address three main science questions: 1) What are the pathways of exchange between the benthic boundary layer and the pelagic ocean in the Peruvian Oxygen Minimum Zone System? 2) What are the ventilation ages of the water masses in the Atlantic OMZ? 3) What is the effective horizontal exchange of oxygen between the OMZ and its surrounding oxygen rich waters in the eastern tropical North Atlantic? All three questions will be addressed using a combination of existing hydrographic data, SFB 754 model results and four targeted field campaigns.

我们将解决三个主要的科学问题：1）秘鲁氧气最小区系统中底栖边界层和远洋海洋之间的交换途径是什么？2)大西洋OMZ中水团的通气年龄是多少？3)在热带北大西洋东部的OMZ和它周围的富氧沃茨之间有效的水平交换是什么？所有这三个问题将使用现有的水文数据，SFB 754模型结果和四个有针对性的现场活动的组合来解决。
