Sentences with phrase «land motion»

The variations in sea level trends seen here primarily reflect differences in rates and sources of vertical land motion.
These are stations not experiencing significant vertical land motion.
Sea level change based on satellite altimetry is measured with respect to the Earth's centre of mass, and thus is not distorted by land motions, except for a small component due to large - scale deformation of ocean basins from GIA.
To extract the signal of sea level change due to ocean water volume and other oceanographic change, land motions need to be removed from the tide gauge measurement.
The estimation of other land motions is not generally possible unless there are adequate nearby geodetic or geological data, which is usually not the case.
Land motions related to GIA can be simulated in global geodynamic models.
Scientists expect regional variations in land motion to continue, and to affect local sea - level rise.3 So, for example, a two - foot (61.0 cm) rise in global sea level would produce a relative sea - level rise of 2.3 feet (70.1 cm) at New York City.3, 17
While there is some difference in these numbers associated with ending the period in 1990 or 1999, the major discrepancies relate to tide guage selections, vertical land motion corrections, area weighting and statistical analysis methods.
An improved calibration of satellite altimetric heights using tide gauge sea levels with adjustment for land motion
To know what these high numbers mean for local changes on the world's coastlines, you need a framework that accounts for all the key drivers: among them not just Antarctica, but also Greenland, mountain glaciers, the expansion of the warming ocean, changes in winds and current, shifts in Earth's gravitational field, and land motion.

They are essentially neutral with respect to vertical land motion, and tide gauges located therein show between 1 mm / yr (3.9 inches / century) and 1.5 mm / yr (6 inches / century rise).
