Laser gyroscope measures tiny fluctuations in Earth’s rotation – Physics World

Lab-sized instrument could shed light on shifting ocean currents

"After 30 years of painstaking development, researchers in Germany and New Zealand have unveiled a laser gyroscope that can track fluctuations in Earth’s rotation in near real time and accurate to several milliseconds. The technique is much simpler than current methods and could provide further insights into phenomena that cause the fluctuations – such as shifts in ocean currents.

The Earth rotates once in one day, but there are tiny fluctuations in the rate and direction of our planet’s rotation. Some of these fluctuations are well understood – for example those caused by the tidal forces of the Moon and Sun.

Other tiny fluctuations are not well understood including those related to the exchange of momentum between the solid Earth and the oceans, atmosphere and ice sheets. These effects can arise from climate events such as the El Niño southern oscillation, which change ocean currents. As a result, measuring fluctuations in Earth’s rotation could shed light on important processes in the atmosphere.

Most rotation studies involve combining data from global satellite navigation systems; very long baseline radio-astronomy observations of quasars; and laser ranging. Due to the complexity of combining these techniques, only one measurement can be made per day.

Now, a team headed by Ulrich Schreiber at the Technical University of Munich has created a laser gyroscope that can measure the tiny fluctuations in near real time. What is more, their instrument can fit into a large room."

Things that happened once a decade are now happening once a month.

The acceleration is real.

Even the north pole is racing towards Siberia.

This is it folks.

New research suggests that as glaciers melt, the planet's axis is shifting.

Excerpt:

A new study in Science Advances suggests that as glaciers melt, the redistribution of mass is making Earth shift and spin faster on its axis. The idea that this might be happening isn’t new. In 2002, an oceanographer named Walter Munk noted that though increasing sea levels should hypothetically shift Earth’s axis and make it spin more quickly, evidence of that shift could not be found.

“Munk’s enigma,” as it was called, was a real headscratcher, writes Choi. He explains that melting mountain glaciers and the loss of the ice cap in Antarctica take weight off of the rock that lies beneath. As the rock juts up, the poles become less flat and Earth becomes more round—a shift in the arrangement of mass that should make the planet spin more quickly.
