A polar cap absorption event results from the ionisation of the D-layer of the polar ionosphere by high energy protons. A PCA causes a HF radio blackout for transpolar circuits and can last several days. PCAs are almost always preceded by a major solar flare with the time between the flare event and the onset of the PCA ranging from few minutes to several hours. 4, record 2, English, - polar%20cap%20absorption%20event

Polar Cap Absorption. The ionisation of the D region over the polar latitudes by high energy solar protons causes radio blackouts for transpolar circuits which can last for several days.

Les éruptions solaires peuvent être accompagnées de flux de particules de très haute énergie se propageant à une vitesse avoisinant celle de la lumière. Ces particules (principalement des protons et des électrons) pénètrent dans la haute atmosphère dans des régions situées près des pôles magnétiques. De ce fait, les niveaux inférieurs de l'ionosphère polaire deviennent très ionisés, ce qui provoque une absorption intense des signaux radioélectriques haute et très haute fréquence. Ce phénomène est connu sous le nom d'absorption à la calotte polaire (ACP) et peut durer plusieurs jours, voire plusieurs semaines dépendant de la puissance du flux des particules solaires et de l'emplacement de la région émettrice sur le Soleil. Il est souvent impossible d'établir des radiocommunications à haute fréquence pendant la durée des évènements d'ACP. 2, record 4, French, - absorption%20au%2Ddessus%20de%20la%20calotte%20polaire

Other disposal options aiming at long-term isolation of wastes from the biosphere were also considered but not pursued, during many years of evolution of the geological disposal strategy. They include: a) disposal concepts such as deposition in polar ice caps or extraterrestrial space which are difficult to implement and poorly controllable; and b) disposal under the deep ocean floor, for which international agreement would be difficult to obtain. 1, record 5, English, - deposition%20in%20polar%20ice%20caps
