Types of Sea Conditions and How to Monitor
Sea is one of the surface of Earth in form of water. In Indonesia, sea is the largest part of area, even compared to the terrestrial ecosystems. Sea plays an important role for the world, because in fact it’s not only in Indonesia that sea area is larger than the terrestrial. On this earth, the area of land is only one third while the water area are two thirds parts. Because sea is very important and influential for the world, we need to understand condition of the sea.
Condition of the sea is very important and must be known, especially for the shipping field. In Oceanography (ie the study of the sea), the condition of the sea is the general condition of free surfaces in large waters that are affected by wind waves and water currents at certain locations and times. The state of the sea includes various things such as ocean waves, current strength, wavelength and even wind power itself. This state of the sea is statistically characterized, including the level of currents, periods and spectrum of strength.
Sea waves are also known as waves. When we go to the high seas, we will feel that the surface of the water in the sea isn’t calm, but always changing. This constantly changing sea level is called waves. Waves vary in magnitude depending on the circumstances. Sometimes the waves will feel big and sometimes even calm. Waves that are too large will certainly be dangerous. The size of this wave depends on several factors and one of them is wind and weather.

In the ocean area, we will find types of wind, including land and sea winds. Land wind is wind that blows from land to sea. This wind blows at night usually. While the sea breeze is the wind that blows from sea to land, and usually blows in the morning. Then it is at these times that the strength of the wind is greater than when outside of these moments.
Is the State of the Sea Changing?
We need to know that the state of the sea is very much influenced by the strength of the wind. This indicates that the state of the sea can change over time in accordance with the strength of the existing wind in the sea. If the wind conditions are strong, the sea waves created are also large even up to several meters and can reach the coastal ecosystem area. while if the wind is not strong, the sea waves are not too big.
Can Sea Conditions Be Monitored?
Regarding sea conditions that can change at any time, does this need to be observed and considered? The answer is of course yes. This is very necessary and very important especially for the world of shipping considering the main terrain is the sea itself. then, who can observe this state of the sea? The state of the sea can be observed by experienced people such as marines who are already trained. The state of the sea can be monitored through several tools such as weather monitors, radar waves and satellites.
