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...
MSL is defined as the zero elevation for a local area. The zero surface referenced by elevation is called a vertical datum. Unfortunately for mapmakers, sea level is not a simple surface. Since the sea surface conforms to the earth’s gravitational field, MSL also has slight hills and valle...
In the same way, the oceans constitute a huge, irregularly-shaped body of water whose surface is disturbed by one cause or another so that its level at any point is constantly changing in elevation. And we conceive mean sea level at any point along the shore as the level of the ocean ...
Because RSL is modeled using GIA, it ensures that we account for processes such as ocean siphoning, which can cause RSL highstands in tropical regions even in the absence of a GMSL highstand5. Fig. 1: Postglacial relative sea level (RSL) data. A Geographic distribution of RSL data. ...

In recent decades, climate change has emerged as a significant issue, causing ongoing increases in ocean and atmospheric temperatures. This trend indicates
The geoid is 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 no
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 ...
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 ...
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...
