- Povzetek: Namen te študije je bila analiza zmanjšanja ravni podvodnega hrupa, izmerjenih v slovenskem morju v letu 2020, ko so bili zaradi razglašene pandemije COVID-19 uporabljeni omejitveni ukrepi. Glede na metodološke standarde za spremljanje in ocenjevanje so bile iz izmerjenih ravni hrupa v letih 2019 in 2020 izračunane letne povprečne vrednosti ravni zvoka v terčnih frekvenčnih pasovih s središčnima frekvencama 63 Hz in 125 Hz. Študija kaže, da so se ravni podvodnega hrupa v slovenskem morju v letu 2020 v primerjavi z letom 2019 zmanjšale zaradi manjšega ladijskega prometa kot posledica omejitvenih ukrepov pandemije COVID-19. Poleg tega je bilo zmanjšanje ravni podvodnega hrupa v letu 2020 potrjeno tudi z modeliranjem ravni podvodnega hrupa s parabolično enačbo na podlagi podatkov o ladijskem prometu iz avtomatskega informacijskega sistema. Na modelirane vrednosti je najbolj vplivala hitrost ladij. Te ugotovitve kažejo, da bi bila uporaba preprostih operativnih ukrepov, kot sta preusmerjanje ladij in omejevanje hitrosti, lahko zelo koristna za to, da bodo morja in oceani v prihodnosti tišji.
