Sea state - Wikipedia
In oceanography, sea state is the general condition of the free surface on a large body of water—with respect to wind waves and swell—at a certain location and moment. A sea state is characterized by statistics , including the wave height , period , and spectrum .

Sea heaps up and white foam from breaking waves begins to be blown in streaks along the direction of wind. Necessary to lean slightly into the wind to maintain balance. Smoke rises at about 5 to 10 deg. Higher pitched moaning and whistling heard from rigging.

Understanding Sea State: A Comprehensive Guide - OUCO
Mar 30, 2023 · Under moderate conditions (sea state 3-4): Waves can reach up to 6 feet and there may be some whitecaps. The progress of offshore operations may be affected, so understanding potential hazards and wearing appropriate safety gear is crucial.
Douglas sea scale - Wikipedia
The Douglas sea scale is a scale which measures the height of the waves and also measures the swell of the sea. The scale is very simple to follow and is expressed in one of 10 degrees.
Beaufort scale - Wikipedia
A ship in a force 12 ("hurricane-force") storm at sea, the highest rated on the Beaufort scale. The Beaufort scale (/ ˈ b oʊ f ər t / BOH-fərt) is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale.
Sea State and Swell | MetService Blog
Combining the Beaufort Scale sea state images – what a mariner would expect the sea to look like – with the expected corresponding wind speeds and the Douglas Sea Scale (figure three), you get figure four.
3 SEA STATE PARAMETERS AND ENGINEERING WAVE SPECTRA
Traditionally sea state is a scale for the average wave height somewhat similar to the Beaufort scale for wind. The most complete wave spectra we are considering are the wavenumber spectrum , and the directional spectrum .
Sea State - wmo.int
Sea State is the characterization of wave and swell, typically in terms of height, wavelength, period, and directional wave energy flux. Waves generated by ocean surface stress evolve from wind waves to swell through nonlinear dynamical processes.. Wave characteristics are modified by bathymetry when the depth of the water is comparable to the ...
Sea State 3 Limitations Mean Failed Operations - Next Navy
May 14, 2018 · By now it should be pretty obvious that the post-Cold War U.S. Navy forgot about high-Sea-State operations…and somehow decided to harness the Navy’s future to a foolish idea that Sea State 3 was a fine operational goal for critical shipboard systems.
