Abstract：An inovative marine fine-scale drifting buoyand its networked observation system were designed.The buoy hardwarefeaturedaself-developed detachable wave-resistant structureand low-power corecomponent integration technology. Withthehelpofitsdual-antennacommunicationarchitecture，thebuoywassubjectedto laboratoryandfieldlaketeststo quantitativelyevaluateitsmeasurementaccuracy，environmentaladaptability，anddatastability.BasedonLoRa-enabled distributedloTcommunicationtechnology，aninovativetopologicalnetworkingarchitecturewasused toconstructafour-node， 10km-scale 3D observation network with a packet loss rate of less than 0.1% .FFTspectral analysis was conducted to analyze datafeatures，andanoise reduction method wasproposed.Testresultsshowed that thenetwork could synchronouslycapture quasi-steady-stateoceanenvironmentaldata，providingascalablesolutionforhigh-density，multi-dimensional，fine-scale oceanmonitoring.The research results were applied in teaching practice.Inaddition，expansion toa10-node network has been planned to advance the engineering application of fine-scale ocean observation technology.
