    Pereira Freitas, Gabriel; Kopec, Ben; Adachi, Kouji; Krejci, Radovan; Heslin-Rees, Dominic; Yttri, Karl Espen; Hubbard, Alun Lloyd; Welker, Jeffrey M.; Zieger, Paul (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-13)
    Mixed-phase clouds (MPCs) are key players in the Arctic climate system due to their role in modulating solar and terrestrial radiation. Such radiative interactions rely, among other factors, on the ice content of MPCs, which is regulated by the availability of ice-nucleating particles (INPs). While it appears that INPs are associated with the presence of primary biological aerosol particles (PBAPs) ...

  • Molecules and Morphotypes – Exploring benthic foraminiferal biodiversity in seep-influenced habitats 

    Holm, Villads Dyrved (Master thesis; Mastergradsoppgave, 2023-05-15)
    Beneath the seafloor, methane, a potent greenhouse gas, is trapped in ice-like structures, prone to destabilization and gas release in a warming climate. Gas releases through the seabed concentrated in seeps, creating unique ecosystems, hostile to some lifeforms but able to sustain others. Foraminifera have proved useful in biodiversity and ecosystem quality assessment due to their ubiquity in ...

    Silt-rich meltwater plume deposits (MPDs) analyzed from marine sediment cores have elucidated relationships that are clearly connected, yet difficult to constrain, between subglacial hydrology, ice-marginal landforms, and grounding-zone retreat patterns for several glacial catchments. Few attempts have been made to infer details of subglacial hydrology, such as flow regime, geometry of drainage ...
  • Acoustic evidence of hydrocarbon release associated with the Spitsbergen Transform Fault, north of the Molloy Ridge, Fram Strait 

    Chand, Shyam; Knies, Jochen Manfred; Geissler, Wolfram H.; Plaza Faverola, Andreia Aletia; Thorsnes, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-16)
    Hydrocarbon gases formed from biotic and abiotic processes are released through the seafloor at different locations around the world. They have been widely observed directly in video and photo data, and indirectly on echosounder data. Even though biotic gas generation is a very common process, abiotic gas generation is limited to regions where serpentinization of ultramafic rocks occur. Indications ...
  • Sedimentological and geochemical investigations of hydrothermally impacted sediments at the Aurora vent field, Fram Strait 

    Bjørnå, Eivind Urbye (Mastergradsoppgave; Master thesis, 2023-05-15)
    Hydrothermal vents are the result of the interaction between seawater and magma and occur at regular intervals along mid ocean ridges. The first visual confirmation of plumes was done in 1977. The detection of hydrothermal plumes has both provided indirect evidence for their existence and a resolution of the occurrences . In deep ocean with low sedimentation rates, hydrothermal plumites have the ...
  • Software Defined Radio Based Avalanche Beacon Receiver 

    Hofsøy-Woie, Vetle (Master thesis; Mastergradsoppgave, 2024-01-24)
    Annually, avalanches claim an average of 100 lives, and many more are injured. For victims buried by an avalanche, time is of the essence. If not rescued within 15 minutes, the victim only has a 10% probability of survival. Commonly, the people venturing into avalanche-prone areas equips avalanche beacons. These devices work as small radio transmitters transmitting a signal at 457 kHz once each ...
  • Hvem bør ha ansvar for kjemilab?

    The Dom Feliciano Belt is the South American part of an extensive Neoproterozoic orogenic system that developed during the late Cryogenian–early Cambrian close to the margin of southwest Gondwana. The link of its evolution with the tectonic processes in its African counterpart is still not well understood. P–T estimates, Lu–Hf garnet–whole-rock ages, U–Pb monazite SIMS ages and REE garnet and monazite ...
  • The Roles of Light Absorbing Particles in the Norwegian Arctic Snow 

    Olanrewaju, Olasubomi Quadri (Mastergradsoppgave; Master thesis, 2023-05-08)
    Light absorbing particles (LAPs) such as black carbon (BC) and dust can reduce snow albedo and have a positive radiative forcing. Previous studies investigating LAP in snow in Tromsø focused on black carbon (BC) also called elemental carbon because it has human sources, but dust should also be considered because, while largely from natural sources, it is present in higher concentrations. To quantify ...
  • Kelvin-Helmholtz versus Gradient drift instability: which one "wins" in the high latitude ionosphere? 

    Kjørsvik, Amalie Marie (Mastergradsoppgave; Master thesis, 2024-01-14)
    The high latitude ionosphere is highly irregular, which is caused by plasma patches, flow shears and electron precipitation. These causes are not well understood, but it is thought to be three sources to these irregularities: density gradients, arcs/flow channels and electron precipitation. It is speculated that there are two main mechanisms for the formation of these irregularities. These mechanisms ...
