次表层漩涡是已知的海洋环流特征，但由于观测的稀疏性，无法评估其对生物地球化学的重要性。在这里，我们使用一个全球涡旋(0.1度)海洋生物地球化学模式，对起源于东部边界上升流系统(EBUS)的次表层相干涡旋进行普查，并量化它们向西传播到副热带环流时的生物地球化学效应。虽然大多数涡流存在几个月，移动距离数百公里，但有一小部分(
Subsurface eddies are known features of ocean circulation, but the sparsity of observations prevents an assessment of their importance for biogeochemistry. Here we use a global eddying (0.1 degrees) ocean-biogeochemical model to carry out a census of subsurface coherent eddies originating from eastern boundary upwelling systems (EBUS) and quantify their biogeochemical effects as they propagate westward into the subtropical gyres. While most eddies exist for a few months, moving over distances of hundreds of kilometers, a small fraction (
