(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 ...
-
(Master thesis / Masteroppgave, 2020)The granitic pegmatites of Tørdal pegmatite field, which are situated in the Vestfold and Telemark county in South Norway, have gained lot of mineralogical and economic interest the last hundred years mainly because of ...

(Master thesis / Masteroppgave, 2023)
-
(Master thesis / Masteroppgave, 2009)Sea surface profile and reflection coefficient estimates are vital input parameters to various seismic data processing applications. The common assumption of a flat sea surface when processing seismic data can lead to ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)[1] Marine cloud brightening through sea spray injection has been proposed as a method of temporarily alleviating some of the impacts of anthropogenic climate change, as part of a set of technologies called geoengineering. ...
-
(Doctoral thesis / Doktoravhandling, 2012)This thesis adresses the problem of how to image the time-varying sea surface based on dual sensor marine seismic data. Although flat and stationary sea surface assumptions may suffice during the processing of marine seismic ...
-
(Master thesis / Masteroppgave, 2020)The role of sea ice in the climate response after the 536 and 540 CE volcanic eruptions hasbeen investigated through MPI-ESM simulations with imposed volcanic forcing. There is aclear response in the Arctic sea-ice cover ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)[1] Among proposed mechanisms for counteracting global warming through solar radiation management is the deliberate injection of sea salt acting via marine cloud brightening and the direct effect of sea-salt aerosols. In ...

Seal, and overburden rock characterization of potential CO2 storage sites in the northern North Sea (Doctoral thesis / Doktoravhandling, 2022)Building confidence in subsurface geological carbon dioxide (CO2) injection project The anthropogenic atmospheric carbon dioxide (CO2) is one of the major greenhouse gases that are responsible for human-induced global ...
-
(Doctoral thesis / Doktoravhandling, 2008)This dissertation was motivated by the realization that four concepts, which are too simplistic, are widely assumed in the petroleum industry: First, mechanical compaction and associated disequilibrium compaction are ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)The fine particulate matter (e.g. PM2.5) gains an increasing concern of human health deterioration. Modelling PM2.5 concentrations remains a substantial challenge due to the limited understanding of the dynamic processes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)A new regional compilation of seamount-like oceanic igneous features (SOIFs) in the NE Atlantic points to three distinct oceanic areas of abundant seamount clusters. Seamounts on oceanic crust dated 54–50 Ma are formed on ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)Using field surveys in 2013, 2014, and 2016 plus satellite data from the 1999–2015 period, we analyze the seasonal drainage cycle of supraglacial lakes on seven debris-covered glaciers in the central Tien Shan. We characterize ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Nordenskiöld Land in Central Spitsbergen, Svalbard is characterized as a high latitude, high relief periglacial landscape with permafrost occurring both in mountains and lowlands. Freezing and thawing of the active layer ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)SUMMARY We processed time-series from seven Global Navigation Satellite System (GNSS) stations and one Very Long Baseline Interferometry (VLBI) station in Svalbard. The goal was to capture the seasonal vertical ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Summer monsoon rainfall forecasting in the Yangtze River basin is highly valuable for water resource management and for the control of floods and droughts. However, improving the accuracy of seasonal forecasting remains a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Measurements of atmospheric nitrogen oxides NOx (NOx = NO + NO2), peroxyacetyl nitrate (PAN), NOy, and non-methane hydrocarbons (NMHC) were taken at the Greenland Environmental Observatory at Summit (GEOSummit) station, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)The Secchi depth and its relationships to other properties of the sea water in the Oslofjord–Skagerrak area have been investigated. White and black disks of different sizes have been applied, and the Secchi depth has been ...
