Core Eigenmodes and their Impact on the Earth's Rotation. [PDF]
Surv Geophys, 2022 Changes in the Earth’s rotation are deeply connected to fluid dynamical processes in the outer core. This connection can be explored by studying the associated Earth eigenmodes with periods ranging from nearly diurnal to multi-decadal. It is essential to

Measurement of the Earth's rotation: 720 BC to AD 2015. [PDF]
Proc Math Phys Eng Sci, 2016 New compilations of records of ancient and medieval eclipses in the period 720 BC to AD 1600, and of lunar occultations of stars in AD 1600–2015, are analysed to investigate variations in the Earth’s rate of rotation.

Reconciling past changes in Earth's rotation with 20th century global sea-level rise: Resolving Munk's enigma. [PDF]
Sci Adv, 2015 Reanalysis of Earth rotation observations reconciles them with globally averaged sea-level change in the 20th century. In 2002, Munk defined an important enigma of 20th century global mean sea-level (GMSL) rise that has yet to be resolved.

ESD Ideas: A 6-year oscillation in the whole Earth system? [PDF]
Earth System Dynamics, 2023 An oscillation of about 6 years has been reported in Earth's fluid core motions, magnetic field, rotation, and crustal deformations. Recently, a 6-year cycle has also been detected in several climatic parameters (e.g., sea level, surface temperature ...

Modeling of the Earth’s rotation variations using a novel approach inspired by the brain emotional learning [PDF]
AUT Journal of Modeling and Simulation, 2022 DT is a quantity that converts universal time (UT; defined by the Earth’s rotation) to terrestrial time (TT; independent of Earth’s rotation). The DT values during the time show the Earth’s rotation variations.

Variations in the Earth’s rotation rate measured with a ring laser interferometer
Nature Photonics, 2023 An exact knowledge of the instantaneous Earth’s rotation rate is indispensable for accurate navigation and geolocation. Fluctuations in the length of sidereal day are caused by momentum exchange between the fluids of the Earth (namely, the atmosphere ...

Earth’s Rotation: Observations and Relation to Deep Interior
Surveys in geophysics, 2021 Observation of the variations in the Earth’s rotation at time scales ranging from subdiurnal to multidecadal allows us to learn about its deep interior structure. We review all three types of motion of the Earth’s rotation axis: polar motion (PM), length
