This review covers basic theory and techniques behind the use of ground-based gravimetry at Earth's surface. The orientation is toward modern instrumentation, data processing interpretation for observing surface, land-based, time-variable changes to geopotential. instrumentation side covered in some detail, with specifications performance most widely used models three main types: absolute gravimeters (FG5, A10 from Micro-g LaCoste), superconducting (OSG, iGrav GWR instruments), new...
Abstract We use tide gauge data spanning from 2005 to 2023 in the Geosciences Laboratory at Lanzarote (Canary Islands, Spain) perform a detailed analysis of local short and long-term changes not previously examined this area. Sea level is affected by spatial temporal climate variability on annual decadal time scales. Consequently, linear trends sea can be difficult even when long series are available. To achieve objective, we investigate multi-year (from 3 10 years) variations through its...
Time-lapse absolute and relative gravity surveys, are directly sensitive to the mass redistribution in subsurface. These well-established methods allow for monitoring of geothermal fields assessing sustainability anthropogenic activities (water injection extraction). We apply hybrid gravimetry method, order characterize fluid within The method combines microgravity time-lapse measurements continuously recorded time series. At Theistareykir field (Northern Iceland), we collected...
We report on the results of a comparative analysis carried out more than ten months co-located records collected at J9 gravity station in Strasbourg (France) with new generation spring gravimeter, Micro-g LaCoste, Inc. gPhone-054 and GWR-C026 superconducting gravimeter (SG-C026). The gPhone is essentially LaCoste & Romberg, model G meter, but an improved thermal system (a double oven) for increased temperature stability, which should result unprecedented improvement noise drift this...
Geotagged smartphone photos can be employed to build digital terrain models using structure from motion-multiview stereo (SfM-MVS) photogrammetry. Accelerometer, magnetometer, and gyroscope sensors integrated within consumer-grade smartphones used record the orientation of images, which combined with location information provided by inbuilt global navigation satellite system (GNSS) geo-register SfM-MVS model. The accuracy these is, however, highly variable. In this work, we use a 200 m-wide...
SUMMARY Taking advantage of the simultaneous recording during 471 d between 2019 and 2021 by two superconducting gravimeters installed at surface 520 m under Low Noise Underground Laboratory (LSBB) in Rustrel, France, we investigate whether a difference tidal gravity signals locations can be detected. First, model periodical variations Earth’s owing to influence from Sun Moon, shallow depths. We provide analytical formulae for Love numbers, gravimetric factor variation simple spherical...
The study is devoted to the monitoring of a geothermal reservoir by hybrid gravimetry combining different types instruments (permanent superconducting gravimeter, absolute ballistic and micro-gravimeters) techniques measurements (both time-discrete recording data collection). Using micro-gravimetric repetition network around reference station, which regularly measured, leads knowledge time space changes in surface gravity. Such can be linked natural or anthropic activities reservoir. A...
SUMMARY We report on about 20 yr of relative gravity measurements, acquired Mt. Somma–Vesuvius volcano in order to investigate the hydrological and volcano-tectonic processes controlling present-day activity volcano. The retrieved long-term field time change (2003–2022) shows a pattern essentially related subsidence, which have affected central part volcano, as detected by permanent GNSS network InSAR data. After reducing observations for effect vertical deformation, no significant residuals...
Following the 2004 seismic unrest at Tenerife and 2011–2012 submarine eruption El Hierro, number of Global Navigation Satellite System (GNSS) observation sites in Canary Islands (Spain) has increased, offering scientists a useful tool with which to infer kinematics present-day surface deformation sector Atlantic Ocean. We take advantage common-mode component filtering technique improve signal-to-noise ratio velocities retrieved from daily solutions 18 permanent GNSS stations distributed...
The great potential of the Global Navigation Satellite System (GNSS) in monitoring ground deformation is widely recognized. As with other geophysical data, GNSS time series can be significantly noisy, hiding elusive signals. Several denoising techniques have been proposed to improve signal-to-noise ratio over years. One most effective has proved multi-resolution decomposition through discrete wavelet transform. However, analysis requires long data sets effective, as well computation times,...
SUMMARY We analyse a nearly 8-yr record (2010–2018) of the superconducting gravimeter OSG-060 located at Djougou (Benin, West Africa). After tidal analysis removing all solid Earth and ocean loading contributions correcting for long-term instrumental drift atmospheric loading, we obtain gravity residual signal which is essentially hydrological due to monsoon. This first compared several global hydrology models (ERA, GLDAS MERRA). Our also superimposed onto episodic absolute measurements...
