Mesoscale eddies have drawn extensive attention due to their central role in ocean energy and mass transport. From July to August 2017, we launched thirteen Petrel-II underwater gliders developed by the Tianjin University, China, in the South China Sea to observe a mesoscale eddy and obtain relatively complete three-dimensional (3D) data. The complex network methodology is advanced to construct a novel Ocean Observation Complex Network (OOCN) with multilayer structure, based on the continuous observation data with higher resolution acquired by Petrel-II gliders. The hierarchical structure of the mesoscale eddy is obtained, which partly validates the three-compartment structure of the eddy. A number of interesting results shows that the dynamic structure analysis can be carried for mesoscale eddies and other complex ocean phenomena.
