Globally, marine dissolved oxygen concentrations have been shown to be in decline. This partly due to the reduced solubility of oxygen in a warming ocean. However global climate models currently disagree in the rate of growth, severity and volume of low oxygen zones in the ocean; likely due to unresolved physical and biogeochemical processes. The aim of the project is to disentangle the physical oceanographic processes the are important for marine deoxygenation, particularly at the smaller scales not often considered in global climate and ocean models.

全球范围内，海洋溶解氧浓度已显示出下降趋势。部分原因是海洋变暖导致氧气溶解度降低。然而，全球气候模型目前在海洋低氧区域的增长速度、严重程度和体积方面存在分歧；可能是由于未解决的物理和生物地球化学过程。该项目的目的是理清对海洋脱氧很重要的物理海洋过程，特别是在全球气候和海洋模型中不经常考虑的较小尺度上。
