Small variations in amplitude (“short” pressure waves) produce weak or quiet sounds, while large variations (“tall” pressure waves) produce strong or loud sounds. The two examples below show sound waves that vary in frequency and amplitude.

We are most familiar with the kind of waves that break on shore, or rock a boat at sea, but there are many other types of waves that are important to oceanography: Internal waves form at the boundaries of water masses of different densities (i.e. at a pycnocline), and propagate at depth.
19 Δεκ 2021 · There are various ways to discern between the different types of ocean waves, viz. by: the disturbing force, i.e. their mechanism of generation; the restoring force, i.e. the mechanism that dampens the wave motion; the length of the wave (wavelength or equivalently wave period or frequency).
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.
Sound Waves and Ocean Acoustics. Acoustic (sound) waves have been called the “daylight” of the ocean. Unlike the air, light in the ocean is absorbed within tens of meters and the vast reaches of the ocean depths are almost completely dark. However, the ocean is largely transparent to acoustic waves.
16 Ιουν 2024 · The channeling of sound waves allows sound to travel thousands of miles without the signal losing considerable energy. In fact, hydrophones, or underwater microphones, if placed at the proper depth, can pick up whale songs and manmade noises from many kilometers away.
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.
