The temporal and spatial variations of low frequency geomagnetic pulsations at polar cusp and cap latitudes
Geomagnetic pulsations Antartica
2015/10/8
Geomagnetic field measurements at two Antarctic stations are compared during two weeks in the local summer (January 1-15, 1992). Low frequency (0.6-6 mHz) pulsations are observed at each station near ...
Spatial variations of 226Ra, 228Ra, and 228Th activities in seawater from the eastern East China Sea
radium isotopes thorium isotopes East China Sea shelf currents seasonal variation water mixing scavenging
2017/4/11
A total of 74 surface and subsurface water samples at depths shallower than 200 m were collected in the eastern East
China Sea (ECS), and spatial and seasonal variations in 226Ra, 228Ra, and 228Th ac...
The spatial variation of coercivity on patterned magneto-optical ~MO! materials has been studied with a Kerr microscope. Our results show that the coercivity values on arrays made by holes are larger ...
Monitoring of temporal and spatial variations in fumarole helium and carbon dioxide characteristics at Poás and Turrialba volcanoes, Costa Rica (2001-2009)
helium isotopes carbon isotopes Central America Costa Rica volcano monitoring
2017/8/9
We report results of a 9-year monitoring program that took place from 2001 to 2009 of the helium and carbon isotope (3He/4He, δ13C) and relative abundances ratios (CO2/3He) of fumarole sites at Poás a...
Seasonal and spatial variations analysis of pollution status of Ondo coastal environment Nigeria using principal component analysis
PCA sediments seasonal and spatial variation metals coastal area
2017/8/9
The variation in environmental quality of Ondo coast between seasons and sites were evaluated using principal component analysis (PCA). Seventeen metals were analysed in water and sediments with five ...
