The invention discloses a tethered balloon system used for marine environmental monitoring. The tethered balloon system can fixedly float in the sea to achieve monitoring and is good in stability performance and easy to transport, install and recycle in the sea. Floating of a tethered balloon is limited within a certain range through a tension leg platform. When the tethered balloon does not rise to a predetermined height yet, buoyancy force produced by gas stored in a compressed gas bag can guarantee normal working of the tension leg platform. When the tethered balloon rises to the predetermined height and starts to perform monitoring, lift force of the tethered balloon provides tension required by stabilization of the tension leg platform, and therefore the design of a pontoon is omitted. Meanwhile, upward traction borne by the tension leg platform can relieve the influence on a bearing platform by a transverse wave load, and therefore the stability of the bearing platform is improved. Besides, the compressed gas bag can be used for storing a certain amount of helium gas, so the height of the tethered balloon is reduced, the tethered balloon is convenient to maintain and recycle, maintenance difficulty and recycling difficulty are lowered, and the helium gas in the tethered balloon can be recycled.
