The Mansurov effect: Seasonal and solar wind sector structure dependence
(Journal article; Peer reviewed, 2023)We investigate the connection between the interplanetary magnetic field (IMF) By-component and polar surface pressure, also known as the Mansurov effect. The aim of the investigation is to unravel potential dependencies ... -
The Mansurov effect: Statistical significance and the role of autocorrelation
(Journal article; Peer reviewed, 2022)The Mansurov effect is related to the interplanetary magnetic field (IMF) and its ability to modulate the global electric circuit, which is further hypothesized to impact the polar troposphere through cloud generation ... -
Mantle exhumation at magma-poor rifted margins controlled by frictional shear zones
(Journal article; Peer reviewed, 2022)The transition zone from continental crust to the mature mid-ocean ridge spreading center of the Iberia-Newfoundland magma-poor rifted margins is mostly composed of exhumed mantle characterized by highs and domes with ... -
Mapping benthic ecological diversity and interactions with bottom-contact fishing on the Flemish Cap (northwest Atlantic)
(Journal article; Peer reviewed, 2020)The ecological diversity of benthic invertebrates from bottom trawl surveys was mapped for the Flemish Cap, a plateau of ~200 km radius in the northwest Atlantic. Species density (SpD), the exponential Shannon diversity ... -
Mapping collinear in-medium parton splittings
(Journal article; Peer reviewed, 2020-01-07)We map the spectrum of 1→2 parton splittings inside a medium characterized by a transport coefficient q^ onto the kinematical Lund plane, taking into account the finite formation time of the process. We discuss the distinct ... -
Mapping Gas Hydrate Dynamics in Porous Media : Experimental Studies of Gas Hydrates as a Source of CH4 and Sink for CO2
(Doctoral thesis, 2020-03-20)The world needs more energy and the energy has to be more sustainable with respect to carbon dioxide (CO2) emissions. This is the backdrop for studying the diverse applications of gas hydrates in nature. The ice-like ... -
Mapping key neuropeptides involved in the melanocortin system in Atlantic salmon (Salmo salar) brain
(Journal article; Peer reviewed, 2023)The melanocortin system is a key regulator of appetite and food intake in vertebrates. This system includes the neuropeptides neuropeptide y (NPY), agouti-related peptide (AGRP), cocaine- and amphetamine-regulated transcript ... -
Mapping Long-Term Changes in Eelgrass Meadows Using Aerial Photography
(Master thesis, 2023-06-02) -
Mapping Microbial Abundance and Prevalence to Changing Oxygen Concentration in Deep-Sea Sediments Using Machine Learning and Differential Abundance
(Journal article; Peer reviewed, 2022)Oxygen constitutes one of the strongest factors explaining microbial taxonomic variability in deep-sea sediments. However, deep-sea microbiome studies often lack the spatial resolution to study the oxygen gradient and ... -
Mapping of fracture corridors in the basement rocks of the Øygarden Complex, Western Norway
(Master thesis, 2019-06-08)Fracture corridors, defined as tabular zones of enhanced fracture intensity, are common features in both sedimentary and crystalline rocks. As potential high permeable structures, research has shown that fracture corridors ... -
Mapping of the Subglacial Topography of Folgefonna Ice Cap in Western Norway—Consequences for Ice Retreat Patterns and Hydrological Changes
(Journal article; Peer reviewed, 2022-06-13)Folgefonna consists of three ice caps which are rapidly retreating in response to warmer temperatures. The melting of Folgefonna has implications for meltwater drainage and hydropower production, as well as the potential ... -
Mapping sediment–landform assemblages to constrain lacustrine sedimentation in a glacier-fed lake catchment in northwest Spitsbergen
(Peer reviewed; Journal article, 2015-10-24)Changes in the deposition of fine-grained rock-flour in glacier-fed lakes reflect glacier variability. This meltwater-driven signal is, however, often overprinted by other processes. To constrain the signature of lacustrine ... -
Mapping stakeholder networks for the co-production of multiple ecosystem services: A novel mixed-methods approach
(Journal article; Peer reviewed, 2022)Governance of ecosystem services (ES) requires an understanding of the complex dynamics of collaboration (and contestation) of multiple stakeholders and multiple ES. However, many studies consider only a few ES or stakeholder ... -
Mapping the amino acid composition of the peripheral membrane binding interface of PH domains
(Master thesis, 2021-11-24)Biological membranes are important in the organization of cells, and the main components of membranes are different kinds of lipids. Peripheral proteins are soluble and interact transiently and bind reversibly to lipids ... -
Mapping the connections : An integrated approach to mapping Nature’s contributions to people in a Nordic biosphere reserve
(Doctoral thesis, 2023-04-24)Naturen og hennes økosystemer gir flere bidrag til mennesker som gagner vår velvære. Disse økosystemtjenestene er truet på grunn av omfattende menneskelige aktiviteter som har resultert i omfattende arealbruksendringer, ... -
Mapping the fugacity of CO2 in the Nordic Seas and the northern North Atlantic Ocean
(Master thesis, 2013-12-20)Self organizing maps (SOMs) have been used to estimate seawater fugacity of CO2 (fCO2) distribution in the Nordic Seas and the northern North Atlantic Ocean for 2005-2007. Four maps were produced for each region using ... -
Mapping the pattern of essential neuroendocrine cells related to puberty and VA opsin expression provides further insight in the photoreceptive regulation of the BPG axis in Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2022)In Atlantic salmon (Salmo salar), seasonal photoperiod is shown to regulate the onset of sexual maturation, yet which brain region(s) is involved, and how light information impacts the neuroendocrine system are still not ... -
Marginalized iterative ensemble smoothers for data assimilation
(Journal article; Peer reviewed, 2023)Data assimilation is an important tool in many geophysical applications. One of many key elements of data assimilation algorithms is the measurement error that determines the weighting of the data in the cost function to ... -
