(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The Lusi mud eruption in East Java, Indonesia, has continued unabated for more than ten years with no end in sight. This review summarizes what has been learned about this intriguing system, from its inception to the current ...
-
(Master thesis / Masteroppgave, 2022)Azerbaijan hosts the largest concentration of mud volcanoes on Earth. This widespread phenomenon occurs due to the combination of unique geological peculiarities. Azerbaijan is characterized by high sedimentation rates ...
-
(Master thesis / Masteroppgave, 2006)Summary Two catastrophic and destructive landslides happened as a consequence of a major earthquake on the midnight of June 20, 1990. Their morphology and dynamic analysis are scope of the present study. The study area ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2014)A number of acquisition constellations for airborne or spaceborne optical images involve small time-lags and produce near-simultaneous images, a type of data which has thus far been little exploited to detect or quantify ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Imaging spectroscopy allows us to identify surface materials by analyzing the spectra resulting from the light–material interaction. In this preliminary study, we analyze a pair of hyperspectral cubes acquired by PRISMA ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Mud volcanism, or sedimentary volcanism, represents one of the most intriguing phenomena of the Earth's crust, with important implications in energy resource exploration, seismicity, geo-hazard and atmospheric budget of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Permafrost is being degraded worldwide due to the change in external forcing caused by climate change. This has also been shown to affect the morphodynamics of active rock glaciers. We studied these changes, depending on ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Abstract. Glacier surface mass balance observations in the Tien Shan and Pamir are relatively sparse and often discontinuous. Nevertheless, glaciers are one of the most important components of the high-mountain cryosphere ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)The Woodfjorden area of northern Spitsbergen (NW Svalbard) offers access to the world’s northernmost onshore thermal springs, extinct Pleistocene alkali basaltic volcanoes and Miocene flood basalts including extensive ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Global-scale solar geoengineering is the deliberate modification of the climate system to offset some amount of anthropogenic climate change by reducing the amount of incident solar radiation at the surface. These changes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Peridotite carbonation represents a critical step within the long-term carbon cycle by sequestering volatile CO2 in solid carbonate. This has been proposed as one potential pathway to mitigate the effects of greenhouse gas ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Study region The Poyang Lake, which is located on the south bank of the middle-lower Yangtze River basin. The lake is the largest freshwater lake in China, and also a typical floodplain lake in the world. Study focus The ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Under the background of global climate change and local anthropogenic activities, multiple driving forces have introduced various nonstationary components into low-flow series. This has led to a high demand on low-flow ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)We reassess the mantle transition zone structure below the northeast Asia margin in the context of subduction of the Pacific plate below the Eurasian continent. We use two independent approaches of teleseismic imaging, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The snow-fed river basins of the Near East region are facing an urgent threat in the form of declining water resources. In this study, we analyzed several remote sensing products (optical, passive microwave, and gravimetric) ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Oversteepened valley walls in western Norway have high recurrences of Holocene rock-slope failure activity causing significant risk to communities and infrastructure. Deposits from six to nine catastrophic rock-slope failure ...
-
(Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2020)High-resolution (1 – 10 m) observations of supraglacial streams are needed to improve process understanding and inform low-resolution (25 – 100 m) remote sensing observations and numerical models. To address this, we built ...
-
(Doctoral thesis / Doktoravhandling, 2018)This PhD aims primarily to assess the long-term sealing capabilities of shaly seal rock units overlying potential adequate CO2 storage reservoirs. The motivation for the project has been that in order to reduce CO2 emissions ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Kerogen lens shape and size distribution control how organic-rich shales may behave as either source or seal rocks. Prior to thermal conversion, kerogen is a brittle, load-bearing constituent of the shale matrix. During ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)In this study, we proposed a new integrated remote sensing drought monitoring indices, i.e. Multiple Remote Sensing Drought Index integrated by Principal Component Analysis (PSDI), Multiple Remote Sensing Drought Index ...
