SKS-Splitting-database

G. Barruol, A. Wuestefeld & G. Bokelmann
The SKS Splitting Data Base is an open-access database. The objective of this database is to facilitate the overview of existing shear-wave splitting measurements and to share the results of the analysis and experiments with everybody. The database contains SKS and direct-S splitting parameters (station names and location, measured azimuth phi and delay time dt and the corresponding errors (if provided in the published data), the phase on which the splitting measurement has been done...

SEIS raw data, Insight Mission

The NASA InSight mission deployed onto Mars' surface the SEIS (Seismic Experiment for Internal Structure) instrument shortly after its landing on November, 26, 2018; a six-axes seismometer equipped with both a long-period three-axes Very Broad Band (VBB) instrument and a three-axes short-period (SP) instrument. These six sensors will cover a broad range of the seismic bandwidth, from 0.01 Hz to 50 Hz, with possible extension to longer periods. Data are transmitted in the form of...

French Global Network of Geomagnetic observatories

The Bureau Central de Magnétisme Terrestre (BCMT) is a French organization founded in 1921 and attached to the Institut de Physique du Globe de Paris (IPGP). Two French institutions are involved in BCMT operations: IPGP and École et Observatoire des Sciences de la Terre de Strasbourg (EOST). The primary mission of the BCMT is to provide ground geomagnetic observations of the highest quality to the scientific community, in France and abroad. To achieve its mission,...

GEOSCOPE, French Global Network of broad band seismic stations

& Ecole Et Observatoire Des Sciences De La Terre De Strasbourg (EOST)
The GEOSCOPE network (G) is a global seismological network created in 1982 to respond to the challenge of instrumenting isolated sites all around the world. The GEOSCOPE network is primarily dedicated to research and its data are used for studies of Earth structure and dynamics, seismic sources, time dependent seismology and environmental seismology. It currently runs 33 seismic stations, all of which are now equipped to provide real-time data, used for rapid source determination (among...

Data from the 2012 AVGR campaign for Lunar and Martian impacts

, James E Richardson & Sharon Kedar
The AVGR is a unique facility, allowing for the experimental investigation of small-scale hypervelocity impacts in a controlled atmosphere and target bed, with a variation of impact velocities and angles. The June 2012 AVGR campaign aimed at investigating impact generated seismic signals on planetary surfaces, taking over from past experiments 40 years before. These new shots were conducted with up-to-date sensors and data reduction techniques. The target material and atmosphere were chosen to reproduce Lunar...

World Digital Magnetic Anomaly Map2.0

Jerome Dyment, Vincent Lesur, Yujin Choi, Mohamed Hamoudi & Erwan Thebault
The WDMAM.2.0 (World Digital Magnetic Anomaly Map) is an international scientific project under the auspices of IAGA (International Association of Geomagnetism and Aeronomy) and CGMW (Commission for the Geological Map of the World), aiming to compile, assemble in a consistent way and make available magnetic anomalies caused by the Earth lithosphere on continental and oceanic areas all over the World. The WDMAM.2.0 data are available at www.wdmam.org (license CC BY-NC 4.0). The method used to...

Modelling to resolve whether SEIS, the seismometer of the NASA Insight lander, has detected the formation of a 1.5m diameter crater which occurred about 40km away.

Carène Larmat, Keisuke Onodera, Ross Maguire & Philippe Lognonné
A new 1.5m diameter crater was discovered on Context camera Images of Mars surface. This crater is relatively close to the NASA InSight lander, at a distance of approximately 40km. Three seismic events were recorded by SEIS, the seismometer of InSight, between the last image without the crater and the second image with the crater. Seismic analysis and modelling were performed in order to test if any of these events is indeed the record of...

GNSS, seismic broadband and strong motion permanent networks in West Indies

The WI network is composed of stations geographically distributed all along the Lesser Antilles subduction zone, from Grenada in the south, to St Barthélémy in the north. The stations all share the following features: (1) very Small Aperture Terminal (VSAT) satellite telemetry, (2) solar power and 10-day battery, (3) multi sensor stations with broadband seismometer (Nanometrics - Trillium120s or 240s) , accelerometer (Kinemetrics - Episensors +/- 2G) and continuous GNSS (Trimble, NetR9), (4) vault and...
