Time Series of Mean Sea Level Trends over Global Ocean

Global or eustatic sea level has fluctuated significantly over Earth's history. The main factors affecting sea level are the amount and volume of available water and the shape and volume of the ocean basins. The primary influences on water volume are the temperature of the seawater, which affects density, and the amounts of water retained in other reservoirs like rivers, aquifers, lakes, glaciers, polar … WebApr 19, 2024 · Global mean sea level has risen about 8–9 inches (21–24 centimeters) since 1880.

Global mean sea level rise is caused primarily by two factors related to global warming: the added water from melting land-based ice sheets and glaciers and the expansion of …

WebMean Sea Level (MSL) has a least two different meanings: 1. For a tide gauge operator, MSL means the 'still water level'. The 'still water level' (without waves) is averaged over some period of time, such as a month or a year. This MSL is measured relative to fixed marks on the land known as 'benchmarks'. WebSea level changes can be driven by variations in the amount of water in the oceans, by changes in the volume of that water, or by varying land elevation compared to the sea surface. Over a consistent time period, conducting assessments can source contributions to sea level rise and provide early indications of change in trajectory.

WebJun 27, 2024 · Mean sea level is the average of the changes in the level of the ocean over time, and it is to this measure that we refer when we use the term sea level.
