Simulation of the Eemian Greenland ice sheet
(Doctoral thesis, 2019-03-05)This thesis focuses on the simulation of the Greenland ice sheet (GrIS) during the Eemian interglacial period (~125,000 years ago). The warm Eemian summers on Greenland are used as a past analogue for future warmer conditions. ... -
Simultaneous tracking of multiple whales using two fiber-optic cables in the Arctic
(Journal article; Peer reviewed, 2023-04-28)Climate change is impacting the Arctic faster than anywhere else in the world. As a response, ecosystems are rapidly changing. As a result, we can expect rapid shifts in whale migration and habitat use concurrent with ... -
Siste istids maksimum og deglasiasjon av nordøstlige deler av Nordsjøen; glasiale prosesser og landskapsformer
(Master thesis, 2012-11-20)Hovedformålet med denne oppgaven har vært å kartlegge glasiale erosjons- og avsetningsformer i nordlige deler av Norskerenna, for å fremskaffe et mer detaljert bilde av Norskerennaisstrømmens tilbaketrekningsmønster, ... -
Skreddersying og optimalisering av separasjonsprosedyrer for isolasjon av kvarts fra bergarter basert på bergartsdannelse og mineralinnhold
(Master thesis, 2017-06-29)Preparering for eksponeringsdatering er en prosess som er både tidkrevende og dyr, hvor bergartsprøvene må gjennom mange delprosedyrer før det aktuelle mineralet er isolert for datering. På Kosmolab benyttes en felles ... -
Skredfarekartlegging i Uskedalen, Kvinnherad kommune - basert på feltobservasjoner, schmidthammermålinger og empiriske modeller
(Master thesis, 2018-06-30)This master thesis is exploring the avalanche hazards in Uskedalen, Norway. Avalanche hazard mapping is an important mitigation measure for hazardous areas. Information about avalanche deposits and terrain gained through ... -
Skredfarekartlegging i Votedalen. Basert på feltobservasjoner, klimastudier, empiriske modeller og dateringsmetoder
(Master thesis, 2016-06-01)Avalanche hazard mapping is an important mitigation measure for hazardous areas. It helps to better understand what areas that need to be secured and what safety measures that should be considered. The combination of such ... -
Skredkartlegging i Austrepollen, Kvinnherad Kommune, Vestland
(Master thesis, 2023-06-15)Skredprosessar er eit stort risikomoment mange stader i Noreg. For å redusera risikoen på menneske, bygg og infrastruktur kan det gjerast skredfarevurderingar for å vurdera tryggleiken til eksisterande strukturar eller ... -
Skredkartlegging i Uskedalen, Kvinnherad kommune, Sunnhordland
(Master thesis, 2018-06-30)Exhaustive knowledge of avalanche trigger mechanisms, dynamics and run-out length is of paramount importance when planning infrastructure. Recognizing active avalanche processes in an area is crucial to determine which ... -
Skredkartlegging og 10Be-eksponeringsdatering av fjellskred i Bondhusdalen, Kvinnherad kommune
(Master thesis, 2022-06-01)I Norge er skred den naturfaren som tar flest menneskeliv. Skred er en landskapsendrende prosess, med hurtige massebevegelser av bergartsfragmenter, løsmasser, vann og snø. Ulike skredprosesser avsetter landformer og ... -
Skuringsstriper og isbevegelse for Hordaland
(Master thesis, 2017-06-27)The main aim for this project is to study the West Norwegian ice dynamics based on the orientation of glacial striations and streamlined landforms. Several authors have previously described the former ice movement in ... -
Some sedimentological and structural studies of the old red sandstone Hitra group, Hitra, Sør-Trøndelag
(Master thesis, 1986-06)The Old Red Sandstone (O.R.S.) area on Hitra contains an about 1350 m thick, continental succession of conglomerates, sandstones and mudstones, here referred to as the Hitra Group. It has further been divided into 3 ... -
Source and receiver deghosting by demigration-based supervised learning
(Journal article; Peer reviewed, 2022)Deghosting of marine seismic data is an important and challenging step in the seismic processing flow. We describe a novel approach to train a supervised convolutional neural network to perform joint source and receiver ... -
Source Study of the 24 August 2016 Mw 6.8 Chauk, Myanmar, Earthquake
(Journal article; Peer reviewed, 2018)The source process of an intraslab intermediate‐depth earthquake (h=90 km) that occurred near Chauk, central Myanmar, on 24 August 2016 was investigated using teleseismic body‐wave inversion. The focal mechanism solution ... -
Source-Sink Analysis of the Pleistocene sediment routing systems within the Wasatch Mountains, Salt Lake City segment, Utah
(Master thesis, 2013-06-03)Source-sink studies consider the sedimentary systems holistically from the erosional hinterland to the depositional basin. Such studies are often challenged by poor constraint on key parameters controlling sediment production, ... -
Sources of uncertainty in Greenland surface mass balance in the 21st century
(Journal article; Peer reviewed, 2022)The surface mass balance (SMB) of the Greenland ice sheet is subject to considerable uncertainties that complicate predictions of sea level rise caused by climate change. We examine the SMB of the Greenland ice sheet in ... -
Southern Ocean bottom-water cooling and ice sheet expansion during the middle Miocene climate transition
(Journal article; Peer reviewed, 2021)The middle Miocene climate transition (MMCT), around 14 Ma, was associated with a significant climatic shift, but the mechanisms triggering the event remain enigmatic. We present a clumped isotope (Δ47) bottom-water ... -
Spatial and temporal variations in minibasin geometry and evolution in salt tectonic provinces: Lower Congo Basin, offshore Angola
(Journal article; Peer reviewed, 2021)In passive margin salt basins, the distinct kinematic domains of thin‐skinned extension, translation and contraction exert important controls on minibasin evolution. However, the relationship between various salt minibasin ... -
