The Investigating Geophysical Unrest at Sierra NegrA (IGUANA) experiment was designed to monitor seismic activity associated with magmatic unrest at Sierra Negra volcano, Galapagos Islands, Ecuador. In late 2017, it was apparent that Sierra Negra was likely approaching a new eruption, and that the volcanic edifice was critically stressed. The experiment captured seismic broadband data during the final approach to eruption, the eruption onset on 26 June 2018, and co-eruptive deflation.

Here we investigate the thermal structure of the lithosphere in the Alpine-Mediterranean region. We focus on areas characterized by negative velocity anomalies according to a lithosphere-upper mantle surface-wave tomography study (El-Sharkawy et al., 2020) to analyze possible lithospheric thinning and melting. Surface-wave, phase-velocity curves were determined by interstation cross-correlation measurements and inverted for a set of phase-velocity maps, spanning a broad period range. We invert fundamental mode Rayleigh and Love dispersion curves together with surface...

The Phanerozoic lithosphere in Central Europe was formed due to the Caledonian and Variscan Orogenies. It then probably underwent modification and thinning associated with widespread and intense Permian volcanism. Since the Permian, the evolution of the Central Europe lithosphere is characterized by various phases of moderate extension and inversion tectonics caused by external forces. Sedimentation and intra-plate volcanism yield evidence for additional intra-plate processes related to variable lithsopheric thickness and deformation. Whereas its crustal structure...

This collection contains figures and movies showing the ExPRES radio source occultations during the Galileo spacecraft Jovian icy moon flybys.

This dataset contains calibrated Cassini-RPWS-HFR Jupiter fly-by data from 6 months of Jupiter encounter: 2000-275 (Oct 1st) 00:00 to 2001-090 (Mar 31st) 24:00. The spectral range covers 3.5 kHz to 16 MHz.

These data represent a series of analyses exploring the seismic behaviours of low-cohesion volcanic sediments – in this case the Neapolitan Yellow Tuff - under varying strain rates. The data include deformation logs from triaxial compression experiments, and the accompanying 12-channel acoustic emission recordings at 10 MHz. These are paired with X-Ray Computed Tomography images of one of the cores from both before and after deformation, to examine damage behaviour. These data include: Deformation logs...

This collection contains Juno/Waves post-processed calibrated datasets with the method described in Louis et al. 2021 (submitted to JGR).

This event list contains start and end times for automatically detected bursts of Auroral Kilometric Radiation (AKR), extracted from Wind/WAVES data. Also provided are the upper and lower frequency limits as a function of time within the burst.

This collection contains post-processed datasets of Wind/Waves flux densities, calibrated with the Z antenna, and containing parameters relevant for the selection of Auroral Kilometric Radiation as described in Waters et al. 2021 (submitted to JGR)
