Polar Motion Dynamics on Slow‐Rotating Venus: Signatures of Mantle Flow
With its 1 day lasting 243 days on Earth, Venus is the slowest‐spinning planet in the Solar System and its rotational bulge is anomalously small. A rotational bulge stabilizes the orientation of planets. Having only a tiny stabilizer, the rotational pole

Cryospheric Excitation on the Earth's Chandler Wobble and Implications From a Warming World
Leveraging Gravity Recovery and Climate Experiment mascon products spanning from April 2002 to September 2023, we, for the first time, ascertain the substantial influence of cryospheric mass variations on Earth's Chandler wobble (CW).

Efficacy of Semen Microencapsulation Technique on the Quality of Spermatozoa From Canindé Goats Kept Under Refrigeration for Three Days. [PDF]
ABSTRACT For approximately 40 years, microencapsulation technology has been utilised across various species due to its ability to release semen gradually after artificial insemination. This study aimed to establish the use of the alginate microencapsulation procedure for goat semen and to investigate whether this method enhances longevity during cold ...

The numerical prediction of the Earth’s polar motion based on an advanced multivariate algorithm
Since there are complicated changes in the polar motion (PM) from sub-annual to decadal, precisely predicting it is challenging. Here, we provide an advanced multivariate algorithm by combining an iterative oblique singular spectrum analysis (IOSSA) with

Abstract Climate model estimates show significant groundwater depletion during the 20th century, consistent with global mean sea level (GMSL) budget analysis. However, prior to the Argo float era, in the early 2000’s, there is little information about steric sea level contributions to GMSL, making the role of groundwater depletion in this period less ...

On Two Formulations of Polar Motion and Identification of Its Sources
Differences in formulation of the equations of celestial mechanics may result in differences in interpretation. This paper focuses on the Liouville-Euler system of differential equations as first discussed by Laplace.

Anthropause environmentalisms: Noticing natures with the Self‐Isolating Bird Club
Short Abstract This paper offers a detailed empirical account of how human‐environment relations were reconfigured in the UK and Ireland during the 2020–2021 COVID‐19 lockdowns, a period which natural scientists defined as the COVID‐19 Anthropause. Bringing this scientific concept into conversation with geographical work, we consider anthropause as ...

Chandler wobble excitation by catastrophic flooding of the Black Sea
It is now widely accepted that during the late Quaternary glaciation the Black Sea formed an isolated inland lake (Ross et al., 1970). New geological data and the recognition of sudden population movements away from the Black Sea coasts suggest that the ...

Chandler Wobble and Free Core Nutation: Theory and Features
Being a torque free motion of the rotating Earth, Chandler wobble is the major component in the Earth’s polar motion with amplitude about 0.05-0.2 arcsec and period about 430-435 days.

A possible interrelation between Earth rotation and climatic variability at decadal time-scale
Using multichannel singular spectrum analysis (MSSA) we decomposed climatic time series into principal components, and compared them with Earth rotation parameters. The global warming trends were initially subtracted.
