Microplate Tectonics Through Earth History and Across Solid Multispheres
The evolution of tectonic microplates throughout Earth´s history as well as the transitions between microplates across different solid spheres offers a novel approach to expanding the traditional plate tectonics theory. ABSTRACT The evolution of tectonic microplates throughout Earth's history as well as the transitions between microplates across ...

Geomagnetic storms of cycle 24 and their solar sources
Solar activity of cycle 24 following the deep minimum between cycle 23 and cycle 24 is the weakest one since cycle 14 (1902–1913). Geomagnetic activity is also low in cycle 24. We show that this low geomagnetic activity is caused by the weak dawn-to-dusk

Geomagnetic Intensity of Hellenistic Pottery and Stamped Rhodian Wine Amphorae From Jerusalem
ABSTRACT Stamped amphora handles produced on Rhodes during the Hellenistic period are well suited for archaeointensity studies because they often bear the names of annually appointed magistrates (eponyms) and fabricants, allowing dating to narrow time intervals.

The occurrence characteristics of 150-km echoes in low-latitude regions are studied using the Equatorial Atmosphere Radar (EAR) in Indonesia. The long-term observation of the 150-km echoes by the EAR enables us to study the occurrence characteristics of ...

Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Forecasting geomagnetic activity
A study of the daily, monthly and annual values of the geomagnetic activity indexAp for 1932 onwards and of the annualaa indices for 1868 onwards indicated that their variations had large random components. Long-term predictions were not possible from time-series extrapolations.

Spatial distribution of temperature during geomagnetic disturbances
We propose an index of efficiency of the solar activity effect on the tropospheric temperature, which takes into account the spatial irregularity of the response to this effect.

Improved satellite‐derived gravity data support updated interpretations and models of ancient plate boundaries and plate motions affecting Zealandia and West Antarctica. The models combine to confidently resolve hundreds of kilometres of Late Cretaceous–Eocene motion between the Pacific and Lord Howe plates, confirming that plate circuit constructions ...
