  1. 1. Drag based forecast for CME arrival

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Simon Jaklovsky; [2020]
    Keywords : CME; ICME; Halo coronal mass ejections; DBM; DBEM; solar wind; interplanetary medium; shock; space weather forecast; geoeffectivity; solar-terrestrial interaction;

    Abstract :           Coronal Mass Ejections (CMEs) are considered to be one of the most energetic events in the heliosphere. Capable of inducing geomagnetic storms on Earth that can cause damage to electronics, a pillar which the modern society we live in leans heavily upon. READ MORE

  3. 2. Constraining the duration of eruptions of the Rangitoto volcano, New Zealand, using paleomagnetism

    University essay from Lunds universitet/Geologiska institutionen

    Author : Linda Aulin; [2017]
    Keywords : Rangitoto; paleomagnetism; paleointensity experiments; Auckland volcanic field; thermal demagnetization; Earth and Environmental Sciences;

    Abstract : The volcano Rangitoto belongs to the Auckland volcanic field and is situated north east of Auckland city, New Zealand. The volcanos of the Auckland volcanic field have previously thought to be of monogenetic origin, but recent studies indicate that Rangitoto has a long history of eruptions, which would suggest that the volcanic system may have entered a new phase.

  4. 3. Palaeomagnetic secular variations in the varved sediments of lake Gościąż, Poland : testing the stability of the natural remanent magnetization and validity of relative palaeointensity estimates

    University essay from Lunds universitet/Geologiska institutionen

    Author : Andreas Nilsson; [2006]
    Keywords : Palaeomagnetism; Holocene varved lake sediments; varve chronology; geomagnetic models; Holocena varviga sjösediment; varvkronologi; geomagnetiska modeller; Earth and Environmental Sciences;

    Abstract : Fyra två meter långa borrkärnor, med sjösediment från Gościąż, Polen, analyserades med hjälp av den s.k. Pseudo-Thellier metoden, en metod som används för att utvärdera tillförlitligheten av variationer av styrkan i det jordmagnetiska (palaeointensiteten) fältet över tiden. READ MORE
