When underwater objects vibrate, they create sound-pressure waves that alternately compress and decompress the water molecules as the sound wave travels through the sea. Sound waves radiate in all directions away from the source like ripples on the surface of a pond.

6 Μαρ 2017 · 2 Types of Ocean Waves and Wave Classification. Ocean waves can be classified in several ways (Kinsman, 1965; Massel, 2013; Holthuijsen, 2007, among others). The most intuitive and commonly used classification is based on the wave period or the associated wavelength.
Period: the time it takes for two successive crests to pass a given point. Frequency: the number of waves passing a point in a given amount of time, usually expressed as waves per second. This is the inverse of the period. Speed: how fast the wave travels, or the distance traveled per unit of time.
19 Δεκ 2021 · We can broadly define ocean waves as all sea-surface variations on the timescale of seconds to months as generated in the oceans. MSL is the sea level you get if you average these fluctuations out. This definition of ocean waves includes wind waves, tides and tsunamis.
16 Ιουν 2024 · Water temperature and pressure determine how far sound travels in the ocean. While sound moves at a much faster speed in the water than in air, the distance that sound waves travel is primarily dependent upon ocean temperature and pressure.
20 Σεπ 2023 · A 5% chance of encountering a single wave higher than 35 ft. (11 m) among every 200 waves that pass in about 30 minutes. A 5% chance of encountering a single wave higher than 40 ft. (12 m) among every 2,600 waves that pass in about five hours.
20 Σεπ 2013 · Sounds emitted under water usually cannot be heard above water. There is a layer of water deep in the ocean known as the Sonar Fixing and Ranging Channel (SOFAR) where the speed of sound is very slow. In the SOFAR channel, low frequency waves may travel thousands of miles before weakening. Minimum sound depth is shallower in temperate waters ...
