Oceans losing breath: Is anthropogenic climate change to blame for recent ocean deoxygenation?

在全球范围内，海洋溶解氧浓度已显示出下降趋势。这在一定程度上是因为氧气在变暖的海洋中的溶解度降低。然而，全球气候模型目前在海洋低氧区的增长速度、严重程度和体积方面存在分歧；这可能是由于尚未解决的物理和生物地球化学过程所致。该项目的目的是理清对海洋除氧非常重要的海洋物理过程，特别是在全球气候和海洋模型中通常不考虑的较小尺度上。

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.
