In oceanography, a 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 power spectrum. The sea state varies with time, as the wind conditions or swell conditions change. The sea state can either be assessed by an experienced observer, like a trained mariner, or through instruments like weather buoys, wave radar or remote sensing satellites.
In case of buoy measurements, the statistics are determined for a time interval in which the sea state can be considered to be constant. This duration has to be much longer than the individual wave period, but smaller than the period in which the wind and swell conditions vary significantly. Typically, records of one hundred to thousand wave-periods are used to determine the wave statistics.
The large number of variables involved in creating the sea state cannot be quickly and easily summarized, so simpler scales are used to give an approximate but concise description of conditions for reporting in a ship's log or similar record.
A sea generally refers to a large body of salt water, but the term is used in other contexts as well. Most commonly, it means a large expanse of saline water connected with an ocean, and is commonly used as a synonym for ocean. It is also used sometimes to describe a large saline lake that lacks a natural outlet, such as the Caspian Sea.
Arctic (belonging to the Arctic Ocean) and Antarctic (Southern Ocean) seas, as well as some other seas freeze in winter. This occurs below the freezing point of pure water, at about -1.8 °C (28.8 °F). Frozen salt water becomes sea ice.
Humans navigated seas from antiquity. Ancient Egyptians and Phoenicians navigated the Mediterranean Sea and the Red Sea. Hannu was the first see explorer of whom there is any information. He sailed along the Red Sea and further to the Arabian Peninsula and the African Coast around 2750 BC. In the 1st millennium BC, Phoenicians and Greeks established colonies all over the Mediterranean, including its outlets like the Black Sea. The seas along the eastern and the southern Asian coast were used by Arabs and Chinese for navigation, and the North Sea and the Baltic Sea were known to Europeans in Roman times. Other seas were not used for navigation in the antiquity and were actually discovered.
State commonly refers to either the present condition of a system or entity, or to a governed entity (such as a country) or sub-entity (such as a province or region).
The world is like a sun in the darkness,
Absu lives in the deep dark, where Cthulu dreams and waits.
The black abyss of the world that can be reached
By some steps a set of seven gates where the place
Of a terrible and evil forces are found.
It is the genius god, the deceiving devil,
The spectrum, the worm of infinite wickedness.
The dead reign will awake and the incience will be over,
Magic will be get by the chosen one.
The seven zones over the earth detailed by the ancient races
That inhabited in Ur, in the lost temples.
These border lands ruled by the celestial spirits are the eternal underworld.
Dead, the death lives,
The reign awaits and the doors of the Duat open up,
Shining light between the monstrosity
That siege in the death.
The fearful dragons, serpents and demons attack to the immortal future,
But with the word of the magic an mortuary text,
Nothing will stop them.
Great reign, oh great reign,
From my body nothing has been taken away.
Nor my viscera, nor my tongue,
And my head hasn't been devoured,
Oh you Osiris, who waits in the reign of the dead,
And your divinity grows up into me and into everyone.
Oh you Osiris, who dies to live due to your brother Seth,
Hail Osiris, our immortal father,
The sweat of their foreheads boils for awaking
From a storm, the traces of your being
Is an intensive death blow,
where your life is made...
Made for the other,
And you can not solve.
Blind human existence, just blind to the
Real passage that carries the life.
Blood runs through your veins,
It's the appearance of the power that flows in your mind,
It's the depressive thought of abnormal strength
A colossal and breathless
Spiritualism in the mental cataclysm of the magic
And power that impregnates from the throne
Everyone is scared that their entry will get soaked in blood,
And their bodies will be consumed by the splendorous devouration
Of the force upon the Earth.
The atmosphere reddens, the doors break down,
The millions vanish in their own nest
The great concavities are hoping to occupy
The reality of cannibalism and the serpent is each time more.
Devoured those who come across,
Slaughtered everyone at his feet,
Destroyed and torn apart
Ancient and vociferating of the deitities,
That take revenge by destroying with the air of the centuries,
The one that's not solicited,
The one who emits the lugubrious crushing sigh,
The energetic, darkness and silent that wrap up the stars,
It's the devil with serpental fangs of the eternal infinity,
With guttural voices on the skies of the spoken leng.
Powerful, capable of razing the valleys and the small earth
With an invisible destruction for the humanity,
Which annoys faceless,
He is heard, whose name is whispered
From an immense and arid,
The offering of eternal life lives.
The gift from heaven, the gift of the great ones
Lays down on Earth.
The valley of the fertile strip
An the red Earth.
United by the great power,
That in day time it reflects the lights
Of the great god and in night
The moon emits its solitude.
Oh you, divine and the greatest one,
Where the prodigious monuments were made in your shores
And if the time destroys and laughs, the wise mocks time.
Oh you, here is the eternity
And the world spoken for themselves and the demons
Whispered and the ancient race
Woke up the manuscripts
Exhaled wickedness of destruction,
Power, death and humiliation,
And the divinities found their ancient
And for all centuries of centuries
And by the black holes,
We will walk through the cosmos
Will shine in darkness
And the space will give us a bath of its rage and its laments.
With the great protection of the chosen one
By the part of the preferences
Invoke the beholder clean and simple,
So that he can be useful,
And with a flaming sword which will surround us.
Our deitities as an offering,
With the burning blaze.
On earth each step is to walk,
Over each step, each portal to enter
with its four poles fired up.
You will hear the messenger spirit of the sphere
That will tell us the name to pronounce before entering,
To the limit of the light stairs.
You will beg to the portal being inside,
And the wisdom;
The power over the spheres will be on you.
The world will be plagued by death, anguish,
The ancient free again,
And they will take their place one more time,
When the tear slides all over the skin,
When the drops form a river of suffering,
And the face begins to fall in pieces like dry and stink scraps.
Already rotten and torn, that by just touching their bodies,
They disappear in the splendor river.
The whole decrepit and buried planet,
Already abandoned in the tombs under the river
With signs and aqueous skulls.
War laments, dying laments,
Internal hate, are like the same
Evilness hammering the weak people's brain.
Beings regretting their decrepitude,
Tied to the hole of nothingness
Dead and absorbed by the desertion of themselves
Without wanting for it but it's too late
To regret in our unexistence.
