“There's an art to it” - Exploring Sami Health Culture and Empowering Communication through an E-health Application
(Mastergradsoppgave; Master thesis, 2024-05-15)Studies have shown that the Sami culture of communicating about health can often be indirect and reliant on implications and hints rather than clear unambiguous statements. The style is described as “roundabout”, circling around a topic before closing in on it. Modern medicine typically values directness and unambiguousness in its mission of effective anamnesis and diagnosis. Due to these differing ... -

The Role of Clouds in Arctic Climate
(Mastergradsoppgave; Master thesis, 2024-05-14)Anthropogenic climate change is causing the Arctic to warm faster than any other region on Earth, a phenomenon also known as Arctic amplification. The warming and its consequences induce, amongst other things, a change in clouds, impacting their role in the Arctic climate by introducing a feedback. Clouds play an important role in the global radiation budget. They cool the surface by reflecting ... -
A distinctive rare earth element signature for pyrite oxidation and glacial weathering
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-15)The application of rare earth elements (REE) and neodymium (Nd) isotopes to authigenic Fe-(oxyhydr)oxide phases leached from marine sediments can be used for reconstructing past ocean circulation and chemical weathering patterns on nearby continental landmasses. To explore the behaviour of REE during chemical weathering in glacial environments, we analyzed the authigenic fraction of glacimarine ... -

Dating and analysis of the Hinlopen Megaslide, northern Svalbard
(Mastergradsoppgave; Master thesis, 2024-05-15)During a research cruise in the summer of 2022, a number of sediment cores were collected from the main headwall scar area of the Hinlopen Megaslide, northern Svalbard. In this study two of those sediment cores have undergone 14C AMS radiocarbon dating and a multi-proxy analysis to determine an accurate age for the slide deposits in this location. The results have been calibrated using the ... -
Marine- and Lacustrine Deposition of Eskers
(Mastergradsoppgave; Master thesis, 2024-05-16)The future stability of modern marine-terminating ice sheets is of great concern as an increased rate of retreat might mark the onset of their collapse. An increased rate of retreat is accompanied by an increase in meltwater and sediment discharge at the ice margin which has prompted research to focus on the drainage system of marine-terminating ice sheets. Recent discoveries of eskers at water-terminating ... -
A sedimentary insight into the coastal and environmental evolution of Hollendarbukta, Isfjorden: Early Holocene to present
(Mastergradsoppgave; Master thesis, 2024-05-13)Dramatic physical and biological shifts are occurring in the Arctic in response to rising surface air temperatures. Sedimentary coastal environments are particularly sensitive to these changes as they form at the interface between the terrestrial and shallow marine realm. The need to investigate sedimentary archives from coastal environments is crucial, to understand how they have responded during ... -
Contrasting Methane Seepage Dynamics in the Hola Trough Offshore Norway: Insights From Two Different Summers
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-09)This study investigates the temporal variations in methane concentration and flare activity in the Hola trough (offshore Norway) during May 2018 and June 2022. Between these time periods, methane seep activity exhibits 3.5 times increase, as evidenced by hydroacoustic measurements. As the seep area in the Hola trough is constantly within the hydrate stability zone, the observed increase cannot be ... -
Better Balance in Informatics: An Honest Discussion with Students
(Chapter; Bokkapittel, 2023-07-09)In recent years, there has been considerable effort to promote gender balance in the academic environment of Computer Science (CS). However, there is still a gender gap at all CS academic levels: from students, to PhD candidates, to faculty members. This general trend is followed by the Department of Computer Science at UiT The Arctic University of Norway. To combat this trend within the CS environment ... -

Problemstillingen søker å identifisere og belyse matematisk tenkning innenfor samisk kunnskap om tradisjonell reinmerking. Dermed ... -
Newly found evidence of the Late Devonian extinction by microtektites in black shales: Sellersburg, Indiana, USA
(Master thesis; Mastergradsoppgave, 2024-05-16)Our planet has experienced at least five major mass extinction events, which have occasionally brought the flora and fauna to almost complete collapse , yet they have been pivotal in the evolution of life as we know it. This thesis explores potential causes of mass extinctions, focusing particularly on the Late Devonian mass extinction event, which is the least understood of the major five. Over the ...
