WebSpeed. How to win a Nobel Prize. Scientists incorrectly believe that tides are caused by the moon's gravitational attraction to seawater, causing the surface of the water to bulge and move around the Earth. If the moon's gravity causes two water bulges that move around the ocean causing tides, we should see two large tides 12 hours apart moving ... WebThey are obtained with the second degree Love and Shida numbers. For sub-centimeter position precision the polar tide corrections need to be applied to obtain an apparent station position; that is, these corrections have to be subtracted from the position solutions in order to be consistent with ITRF. Unlike the solid earth tides and the ocean ...

WebA Correction Strategy for Instrument Drift and Tides. The result of the drift and the tidal portions of our gravity observations is that repeated observations at one location yield different values for the gravitational acceleration. The key to making effective corrections for these factors is to note that both alter the observed gravity field as slowly varying … WebAs Earth rotates within this layer of water, its landmasses pass through the two bulges.
