Vedenalaisuus refers to the state or condition of being underwater. It encompasses the vast realm beneath the surface of oceans, lakes, rivers, and other bodies of water. This environment is characterized by unique physical properties such as pressure, temperature, light penetration, and water currents, all of which vary significantly with depth and location.
