The Hydrometer as a Seismometer [PDF]
Nature, 1905 A SHORT time ago (NATURE, May 25) I directed attention to a misconception which seemed to prevail among seismologists as to the behaviour of a spirit-level. It may perhaps be useful to point out another fallacy, also of an elementary hydro-mechanical nature, involved in some of the unsuccessful attempts to record vertical motion.

Resonances of the InSight Seismometer on Mars
Bulletin of the Seismological Society of America, 2021 ABSTRACT The Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) seismometer was deployed to the surface of Mars in December 2018–February 2019. The specific deployment conditions, which are very different from those of a standard broadband instrument on the Earth, result in resonances caused by ...

PERFORMANCE OF RESONANT SEISMOMETERS [PDF]
GEOPHYSICS, 1954 A group of resonant vertical seismometers, each tuned to cover a part of the spectrum of microseism frequencies, has been operated for about one year. These instruments (a) clearly distinguish between simultaneous microseisms from two separate sources; (b) show an improved signal‐to‐noise ratio for microseisms from a single storm, permitting earlier ...

Seismometer Detection of Dust Devil Vortices by Ground Tilt [PDF]
, 2015 We report seismic signals on a desert playa caused by convective vortices and dust devils. The long-period (10-100s) signatures, with tilts of ~10$^{-7}$ radians, are correlated with the presence of vortices, detected with nearby sensors as sharp ...

Subtraction of Newtonian Noise Using Optimized Sensor Arrays [PDF]
, 2012 Fluctuations in the local Newtonian gravitational field present a limit to high precision measurements, including searches for gravitational waves using laser interferometers.

, 2020 The cancellation of noise from terrestrial gravity fluctuations, also known as Newtonian noise (NN), in gravitational-wave detectors is a formidable challenge. Gravity fluctuations result from density perturbations associated with environmental fields, e.

Differential phase extraction in an atom gradiometer [PDF]
, 2015 We present here a method for the extraction of the differential phase of an atom gradiometer that exploits the correlation of the vibration signal measured by an auxiliary classical sensor, such as a seismometer or an accelerometer.
