Methane monitoring apparatus and system for stereoscopic and real-time methane monitoring of ocean profile

A methane monitoring apparatus, comprising:

• a plurality of first floating ball assemblies for submerging, wherein each first floating ball assembly comprises at least two floating ball that are vertically stacked and coupled to a fixing rope,
• a real-time monitoring module comprising an ocean current meter, a Conductivity Temperature Depth (CTD), and a methane sensor, each of which is hard-wired to a common data acquisition cabin for simultaneous time-stamped acquisition of ocean current, temperature, salinity, and methane content,
• a data acquisition cabin for processing monitored data,
• a first communication module connected with an external communication apparatus, and
• a fixing rope for connecting the plurality of first floating ball assemblies and the data acquisition cabin, wherein
• the real-time monitoring module is connected with the first communication module through the data acquisition cabin, and the plurality of first floating ball assemblies are connected to the data acquisition cabin through the fixing rope, wherein the first communication module communicates with outside of the methane monitoring apparatus, and the fixing rope does not communicate with the outside of the methane monitoring apparatus.
