Mesocosm/Mesocosm experimental system, marine mesocosm facility, pelagic mesocosm experiment, aquatic mesocosm setup, land-based ocean mesocosm
Mesocosms are partially closed experimental outdoor systems used for the simulation of biological, chemical, and physical processes. They bridge the methodological gap between laboratory experiments and field observations, serving as an important part of climate research to experimentally simulate different future climate scenarios. The pools are filled with natural seawater and accommodate various flora and fauna (algae, shells, macro plankton, etc.) to evaluate the impact of changing environmental conditions and climate change.

Tsunami Buoy/tsunami early‑warning, oceanographic, metocean, real‑time telemetry, deep‑sea, coastal warning system, pressure sensor, bottom pressure recorder(BPR), data logger, offshore deployment
The Frankstar Tsunami Buoy (TB) is a comprehensive system designed for deep-sea tsunami monitoring and early warning applications. It consists of a surface buoy body, seabed base station, underwater acoustic communication link, and satellite communication module. Adopting an architecture of seabed sensing, surface relay, and satellite data transmission, the system continuously monitors tiny variations in seawater pressure via high-precision pressure detectors deployed on the seabed, identifying water level fluctuations caused by tsunamis through data algorithms. During operation, the seabed base station collects, processes, stores, and transmits pressure data via underwater acoustics to the surface buoy, which then sends the data back to the shore receiving center via satellite.

CONTROS HydroC CH₄ FT
The CONTROS HydroC CH₄ FT is a professional flow-through methane partial pressure sensor. It is engineered for continuous flow measurement scenarios, including pumped stationary monitoring stations and ship-based underway observing systems such as FerryBox.The instrument utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS) to detect dissolved methane. Water flows through the sensor flow cell; dissolved methane penetrates the composite membrane and enters the internal gas detection chamber for precise analysis. Every unit undergoes independent water tank calibration to guarantee reliable short-term and long-term measurement accuracy.Typical application fields cover global climate research, marine methane hydrate surveys, limnological observation, freshwater environmental regulation, aquaculture and fish farming water quality monitoring. -
CONTROS HydroC® CO₂ FT
The CONTROS HydroC® CO₂ FT is a unique surface water carbon dioxide partial pressure sensor designed for underway (FerryBox) and lab applications. Fields of application include ocean acidification research, climate studies, air-sea gas exchange, limnology, fresh water control, aquaculture/fish farming, carbon capture and storage – monitoring, measurement and verification (CCS-MMV).
