IR SPECTRAL MAPPING OF THE MARTIAN SOUTH POLAR RESIDUAL CAP USING CRISM [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Polycyclic aromatic hydrocarbons (PAHs) are considered to be important in theories of abiogenesis (Allamandola, 2011) . There is evidence that PAHs have been detected on two icy Saturnian satellites using the Visual and Infrared Mapping Spectrometer ...

Multi-instrumentation observations of a transpolar arc in the northern hemisphere [PDF]
Annales Geophysicae, 2008 A transpolar arc was imaged by the FUV instrument on the IMAGE spacecraft during a 3-h interval on 5 February 2002. Observations indicate that a burst of reconnection in the geomagnetic tail, which was not associated with a substorm, was responsible ...

Seasonal variations and north–south asymmetries in polar wind outflow due to solar illumination [PDF]
Annales Geophysicae, 2016 The cold ions (energy less than several tens of electronvolts) flowing out from the polar ionosphere, called the polar wind, are an important source of plasma for the magnetosphere.

Substorms and polar cap convection: the 10 January 2004 interplanetary CME case [PDF]
Annales Geophysicae, 2012 The expansion-contraction model of Dungey cell plasma convection has two different convection sources, i.e. reconnections at the magnetopause and in the magnetotail.

Positive storm effects in the dayside polar ionospheric F-region observed by EISCAT and ESR during the magnetic storm of 15 May 1997 [PDF]
, 2002 International audienceEISCAT/ESR radar data and in situ FAST and POLAR satellite observations are coordinately analyzed to investigate positive ionospheric storm effects in the dayside upper F-region in both the polar cap and the auroral oval during the ...

Space weather with an arc’s ∼2 h trip across the nightside polar cap
Frontiers in Astronomy and Space SciencesFlow channels can extend across the polar cap from the dayside to the nightside auroral oval, where they lead to localized reconnection and auroral oval disturbances.

Mechanism of the chromosome-induced polar body extrusion in mouse eggs
Cell Division, 2011 Background An oocyte undergoes two rounds of asymmetric division to generate a haploid gamete and two small polar bodies designed for apoptosis. Chromosomes play important roles in specifying the asymmetric meiotic divisions in the oocytes but the ...

Initial results from Soviet unmanned magnetometer network in Antarctica
Antarctic Record, 1986 During the last decade the unmanned magnetometer network across the southern polar cap along geomagnetic meridian 110°between corrected geomagnetic latitudes -75 and -89°has been successfully operated.

Polar observations of electron density distribution in the Earth’s magnetosphere. 1. Statistical results [PDF]
Annales Geophysicae, 2002 Forty-five months of continuous spacecraft potential measurements from the Polar satellite are used to study the average electron density in the magnetosphere and its dependence on geomagnetic activity and season.
