The numerical prediction of the Earth’s polar motion based on an advanced multivariate algorithm
Frontiers in Astronomy and Space Sciences, 2023 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

Anthropause environmentalisms: Noticing natures with the Self‐Isolating Bird Club
Transactions of the Institute of British Geographers, Volume 48, Issue 2, Page 232-248, June 2023., 2023 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 ...

On Two Formulations of Polar Motion and Identification of Its Sources
Geosciences, 2022 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.

On a possible connection between Chandler wobble and dark matter [PDF]
, 2009 Chandler wobble excitation and damping, one of the open problems in geophysics, is treated as a consequence in part of the interaction between Earth and a hypothetical oblate ellipsoid made of dark matter.

Make me a test and I will save the world: towards an anthropology of the possible in global health
Journal of the Royal Anthropological Institute, Volume 29, Issue S1, Page 95-113, April 2023., 2023 Abstract What is deemed possible in the wake of failure? The global biotech industry's failure to develop affordable diagnostic devices for use in low‐ and middle‐income countries (LMICs) has inspired a generation of humanitarian entrepreneurs to launch their own diagnostic start‐up companies. This essay traces the rise and fall of one such start‐up in

The Earth’s variable Chandler wobble [PDF]
Astronomy & Astrophysics, 2011 Aims. We investigated the causes of the Earth’s Chandler wobble variability over the past 60 years. Our approach is based on integrating of the atmospheric and oceanic angular momentum computed by global circulation models. We directly compared the result of the integration with the Earth’s pole coordinate observed by precise astrometric, space, and ...

Are Ocean Reanalyses Useful for Earth Rotation Research?
Earth and Space Science, Volume 10, Issue 3, March 2023., 2023 Abstract Oceanic circulation and mass‐field variability play important roles in exciting Earth's wobbles and length‐of‐day changes (ΔΛ), on time scales from days to several years. Modern descriptions of these effects employ oceanic angular momentum (OAM) series from numerical forward models or ocean state estimates, but nothing is known about how ocean

Chandler wobble excitation by catastrophic flooding of the Black Sea
Annals of Geophysics, 1999 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 ...

A possible interrelation between Earth rotation and climatic variability at decadal time-scale
Geodesy and Geodynamics, 2016 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.
