Sea level,also referred to as mean(平均的) sea level is the level at which the oceans exist when averaged between high and low tides.It is calculated by measuring the level of the oceans over long periods of time and under all types of weather conditions. (1) E For instance,the height...
In many cases the real content of the physical concept N of mean sea level is typically this no-no character. "Mean" is — following this concept — the rejection of every thing that could be qualified as being " special" .P. J. Wemelsfelder...

Theis defined as the surface of the earth's gravity field, which approximates mean sea level. It is perpendicular to the direction of the force of gravity. Since the mass of the Earth is not uniform at all points, the magnitude of gravity varies, and the shape of the geoid is irregular...
In recent decades, climate change has emerged as a significant issue, causing ongoing increases in ocean and atmospheric temperatures. This trend indicates
The model is applied to cyclone-induced flooding in the GBMD during Cyclone Sidr. The control simulation uses the MSL in 2000 as the MSL condition. Three different MSL rise scenarios: 0.5 m, 1 m, and 1.5 m, which cover the projected sea level rise scenarios in the BoB from the fifth ...
First, it is apparent that there is seasonal variability in mean sea level along the WIC (as shown in Bertin et al. (2015)), but this has not been assessed in detail to date nor with an evaluation of regional variations along the coast. The inter-annual variations along the Eastern ...
Accurate characterization of Last Interglacial (MIS 5e; ∼129–116 ka) sea level is important for understanding ice sheet sensitivity to climate change, with implications for predicting future sea-level rise. Here we present a record of MIS 5e sea level based on high-precision U-series ages ...
Altimeter data provide a useful complement to tide gages for monitoring the mean sea level or the continental ice topography. We discuss here how these signals can be separated from measurement errors and from other ocean signals. With existing data, the formal error which can be achieved is of...
30,31). The Greenland Ice Sheet was identified as the greatest source of uncertainty associated with the ice sheet contribution to GMSL for 18% of responses for 2100 and 13% for 2300. Uncertainty of the sea level contribution from the Greenland Ice Sheet is dominated by surface mass balance...
