Possible earthquake precursors revealed by LF radio signals
Possible earthquake precursors LF radio signals
2009/12/9
In this case, it is possible that the pre-seismic processes could have produced irregularities in the troposphere, such as ducts, reflecting layers and scattering zones, so that some local troposphere...
A pre seismic radio anomaly revealed in the area where the Abruzzo earthquake (M=6.3) occurred on 6 April 2009
pre seismic radio anomaly Abruzzo earthquake (M=6.3)
2009/12/8
On 6 April 2009 a strong (Mw=6.3) earthquake occurred in the Abruzzo region (central Italy). Since 1996, the intensity of CLT (f=189 kHz, Sicily, Italy), MCO (f=216 kHz, France) and CZE (f=270 kHz, Cz...
Climatic transitions in the Arctic as revealed by mineralogical evidence from the Upper Cenozoic sediments in the central Arctic Ocean and the Yermak Plateau
Climatic transitions mineralogical evidence Upper Cenozoic sediments central Arctic Ocean
2009/12/2
Mineralogical characteristics of the sediments can be used to evaluate critical climate transitions in the Arctic Ocean based on a close relationship between ice-sheet initiation, ice rafting and sea-...
The South Anyui suture,Northeast Arctic Russia,revealed by offshore seismic data
South Anyui suture Northeast Arctic Russia offshore seismic data
2009/12/2
The closure of the Anyui oceanic basin is expressed in western Chukotka by Mesozoic terrigenous turbidite and fragments of both Paleozoic and Mesozoic ophiolite sequences, the South Anyui suture. Howe...
Large regional-scale variation in C3/C4 distribution pattern of Inner Mongolia steppe is revealed by grazer wool carbon isotope composition
regional-scale variation C3/C4 distribution pattern Inner Mongolia steppe isotope composition
2010/1/20
This work explored the spatial variation of C3/C4 distribution in the Inner Mongolia, P. R. China, steppe by geostatistical analysis of carbon isotope data of vegetation and sheep wool. Standing commu...
Relative stability of soil carbon revealed by shifts in δ15N and C:N ratio
Relative stability soil carbon shifts δ15N C:N ratio
2010/1/15
Life on earth drives a continuous exchange of carbon between soils and the atmosphere. Some forms of soil carbon, or organic matter, are more stable and have a longer residence time in soil than other...
Possible seismo-ionosphere perturbations revealed by VLF signals collected on ground and on a satellite
Possible seismo-ionosphere perturbations VLF signals satellite
2009/12/30
The results of the monitoring of three VLF/LF signals collected in Petropavlovsk station (Kamchatka, Russia) and one VLF signal collected on board of the DEMETER French satellite are presented. Two pe...
