Intense, potentially dangerous standing waves – seiches – can penetrate the Round Bay south of Sevastopol from other bodies of water. This was shown by a study by scientists from the Institute of Marine Hydrophysics of the Russian Academy of Sciences (MGI RAS). The Ministry of Education and Science told socialbites.ca about the results.
The round bay south of Sevastopol is connected to other bays and together form a little-studied system. In a new study, scientists from MHI RAS and other institutes obtained data from direct long-term observations of sea level in Krugloya Bay for the first time.
A special ultrasonic sea level meter was placed on one of the concrete supports of a disused pier, 35 meters offshore, at a depth of 1.7 meters. Two months of volatility data were analyzed using mathematical modelling. Scientists have found that intense seiche vibrations can occur in Kruglaya Bay, which are standing waves that occur in closed and partially closed water bodies.
“Due to the connection in the bay system, waves from one bay can penetrate into the neighbors. In the literature they are called “strangers”. The intensity of “foreign” emissions can significantly exceed the intensity of a given bay’s own emissions and pose a danger to ships and coastal infrastructure. Senior Researcher, Candidate of Physical and Scientific Sciences at the Department of Wave Theory, MHI RAS, we found that in the Kruglaya Bay there is a wide variety of seiches, including oscillations determined not only by the parameters of the Kruglaya Bay, but also in neighboring bays. Mathematical Sciences, socialbites.ca told Yuri Manilyuk.
Researchers plan to create a sensor network for long-term monitoring of long-wave oscillations in all bays of Sevastopol, study wave regimes and evaluate possible hazards associated with fogs. This will allow you to be warned of threats in advance and take the necessary security measures.
