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.
21 Δεκ 2022 · We find that about 30–40% of the global ocean experienced robust seasonal trends in mean and extreme wave height, period, and direction.
6 Μαρ 2017 · Depending on the location among many other factors, tides can assume a period of 12.25 h, when two almost equal high tides and two low tides occur each day (semidiurnal tide), and/or 24.5 h, when one high tide and one low tide is expected each day (diurnal tide).
7 Νοε 2023 · As the underlying surface of the atmospheric boundary layer, the sea surface plays an important role in atmosphere–ocean coupling simulations [18, 19]. The common parameterization schemes of ocean waves include the parameterization of the wave height, drag coefficient, and wave period.
20 Απρ 2022 · The short-term statistics of wave conditions in coastal waters around the United Kingdom have been investigated using over 40,000 half-hour long sea state records with significant wave height greater than 3 m. The extensive data set facilitates an assessment of various wave height and period distribution models in shallow and intermediate waters.
To compare noise levels in water to noise levels in air, one must subtract 26 dB from the noise level referenced in water. For example, a supertanker radiating noise at 190 dB (re 1µPa @ 1m) has an equivalent noise level in air of about 128 dB (re 20µPa @ 1m).
