An accurate measurement of sea level is very hard to pin down. But it is an important measurement for two main reasons:
The problem with measuring the sea level is that there are so many things that perturb it. If you could take planet Earth and move it out into deep space so that the sun, moons and other planets did not affect it and there were no temperature variations worldwide, then everything would settle down like a still pond. Rain and wind would stop, and so would the rivers. Then you could measure sea level accurately. If you did this, the level of the ocean's water projected across the entire planet would be called the geoids. On land, you can think of the geoids as the level that ocean water would have if you were to dig a canal from the ocean's shore to any point on land.
But the Earth is not in deep space -- it is in the middle of a chaotic solar system. There are all sorts of things changing the water level at any given point, including:
If you were to stand on the ocean shore and try to measure sea level with a ruler, you would find it to be impossible -- the level changes by the second (waves), by the hour (tides) and by the week (planetary and solar orbit changes). To get around this, scientists try using tide gauges. A tide gauge is a large (1 foot [30 cm] or more in diameter), long pipe with a small hole below the water line. This pipe is often called a stilling well. Even though waves are changing the water level outside the gauge constantly, they have little effect inside the gauge. The sea level can be read relatively accurately inside this pipe. If read on a regular basis over a time span of years and then averaged, you can get a measurement of sea level.
You can see that getting an accurate reading (for example, down to the millimeter level) is extremely difficult. Satellites are now used as well, but they suffer from many of the same problems. Scientists do the best they can, using extremely long time spans, to try to figure out what the sea level is and whether or not it is rising.
LMS is taken this as serious in order to solve the problem of its customers and is soon going to launch the variety of tide gauges which are best in present market of tide gauges.
