The period and Q of the Chandler wobble [PDF]
The calculation of the theoretical period of the Chandler wobble is extended to account for the non-hydrostatic portion of the earth's equatorial bulge and the effect of the fluid core upon the lengthening of the period due to the pole tide. The theoretical period of a realistic perfectly elastic earth with an equilibrium pole tide is found to be 426.7

Estimation of period and Q of the Chandler wobble [PDF]
SUMMARY The period P and Q-value of the Chandler wobble are two fundamental functionals of the Earth's internal physical properties and global geodynamics. We revisit the problem of the estimation of P and Q, using 10.8 yr of modern polar motion as well as contemporary atmospheric angular momentum (AAM) data.

On a possible connection between Chandler wobble and dark matter [PDF]
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.

The bumble bees (Hymenoptera: Apidae: Bombus) of Arkansas, fifty years later [PDF]
Many species of bumble bees (Hymenoptera: Apidae: Bombus Latreille) are declining throughout their ranges in North America, yet detecting population trends can be difficult when historical survey data are lacking. In the present study, contemporary data

Is the Chandler period variable? [PDF]
Summary. This paper investigates whether the Chandler period is variable in time. The first step is to develop an Instantaneous Frequency Analysis to trace the time-varying spectrum for a non-stationary , complex-valued time series. The method is then applied to the observed polar motion to find no significant fluctuation of the Chandler period.

Orbital Complications of Acute Sinusitis in Pediatric Patients: Management of Chandler III Patients
Background Surgery is often avoided in the setting of pediatric orbital complications from acute sinusitis unless necessitated by alarming ophthalmological signs. Criteria for surgical intervention are not well-defined.

Observations of late-winter marine microbial activity in an ice-covered fjord, west Greenland [PDF]
Direct observations of marine microbial metabolism are sparse in the Arctic, particularly under sea ice during winter. This paper presents the first observations of Arctic winter microbial activity under sea ice in a west Greenland fjord (Lillefjord ...

Polyphony of Short-Term Climatic Variations
It is widely accepted to believe that humanity is mainly responsible for the worldwide temperature growth during the period of instrumental meteorological observations. This paper aims to demonstrate that it is not so simple.

Is the Chandler Period Stable? [PDF]
The problem on Chandler period is an unsolved one. Several authors suggested a hypothesis that the Chandler wobble is only one free period which slightly changes in time and is amplitude-dependent. In this paper we shall make the hypothesis more rigorous than that has been carried yet.
