Russian scientists create climate-active substances monitoring system in the Arctic Ocean

03 march 2025

Scientists from the Shirshov Institute of Oceanology (IO RAS) have developed Russia’s first climate monitoring system in the Arctic, which includes both ship-based and autonomous systems for observing the state of the natural environment.

According to the statement from the institute cited by TASS, the system will ensure effective monitoring of all parameters of the near-surface atmosphere and the surface layer of the ocean, allowing for stable assessments necessary for closing regional balances of gas and energy flows in the ocean.

The data obtained from the hydrometeorological station made it possible for the first time to measure quantitative characteristics of the variability of energy flows and greenhouse gases between the ocean and the atmosphere in real time.

"The key element of the system developed by the IO RAS scientists was the Sea-Air-Wave Station (SAWS), a hydrometeorological station tested during last year's Arctic expedition. Measurements of greenhouse gas concentrations demonstrated the high efficiency of the gas analyzers installed at the SAWS station," the scientists noted.
