(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The temperature distribution of shallow sectors of coastal aquifers are highly influenced by the atmospheric temperature and recharge. However, geothermal heat or vertical fluxes due to the presence of the saline wedge ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The late Permian biotic crisis had a major impact on marine and terrestrial environments. Rising CO2 levels following Siberian Trap volcanic activity were likely responsible for expanding marine anoxia and elevated water ...

Sammenheng mellom regionale hydrometeorologiske forhold og poretrykk mht. utløsning av løsmasseskred (Master thesis / Masteroppgave, 2019)Fremtidens klima kommer til å føre til flere store nedbør- og snøsmeltingshendelser. I dag utgjør dette en stor del av utløsende årsak for løsmasseskred. Det vil si at for å minimere skadeomfanget som kan oppstå med ...

(Master thesis / Masteroppgave, 2007)Clouds cover about 70% of the earth. In 1983 the world first satellite program, called International Satellite Cloud Climatology Project (ISCCP), was established. ISCCP use geostationary and polar orbiting satellites to ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Studying the geology of a terrestrial body and its evolution requires being able to set up a chronology. Crater statistics is a powerful tool to do so. However, calibration of this method, which is derived ...
-
(Master thesis / Masteroppgave, 2014)Robuste estimater for vannføring avhenger av pålitelige inndata, som temperatur og nedbør. Målstasjoner ligger ofte spredt, dette gjør at lokal temperatur og nedbør må interpoleres fra omkringliggende målestasjoner. Kunnskap ...
-
(Master thesis / Masteroppgave, 2018)Mobility of sand by fluidization, so-called sand tectonics, can drive surface movements and thereby have a significant impact on depositional environments. Deformation related to sand mobilization is a typical understudied ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)In the days to weeks following an earthquake, landslides can display specific post-seismic motions, including delayed initiations and post-seismic relaxations. These motions have an uncertain origin, sometimes attributed ...
-
(Master thesis / Masteroppgave, 2023)The sarcopterygian fishes are today represented by the two groups Actinistia (coelacanths) and Dipnoi (lungfish). Both groups survived the end-Permian mass extinction (EPME), after which the coelacanths rapidly achieved ...
-
(Master thesis / Masteroppgave, 2019)Potential field analysis is known to suffer from the problem of "non-uniqueness" in solutions. Gravity data interpretation is a prime example. Anomalous bodies can be detected from the gravity field, but information regarding ...
-
(Master thesis / Masteroppgave, 2019)All countries are affected by natural hazards in different ways. The recently launched Synthetic Aperture Radar (SAR) Sentinel-1 A and B twin satellites provides large amounts of high-resolution radar data due to their, ...
-
(Master thesis / Masteroppgave, 2008)Til tross for at isskred fra breer sjelden forekommer, utgjør disse en kontinuerlig fare for menneskeliv og infrastruktur lokalisert i nærområdene. Skred fra bratte breer kan forekomme som en naturlig del av ablasjonsprosessen ...
-
(Master thesis / Masteroppgave, 2018)Precipitation patterns and rates change with global warming. These changes can be separately evaluated in fast and slow responses, the combination of the two are called apparent responses. The fast precipitation responses ...
-
(Master thesis / Masteroppgave, 2007)Aerosol particles , such as sulfate aerosols, can act as cloud condensation nuclei (CCN). The CCN spectrum and water vapor supply in a cloud determine the cloud droplet number concentration (CDNC) and hence shortwave optical ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)Abstract The ScanArray international collaborative program acquired broadband seismological data at 192 locations in the Baltic Shield during the period between 2012 and 2017. The main objective of the program ...
