Normal Incidence Ultrasonic Beam Transmission Through Steel Plates. Measuring and Modelling The Transmission Coefficient
(Master thesis, 2020-06-30)Ultrasonic beam transmission through solid plates has been extensively studied overthe past decades. Through this study many anomalies have been found, that plane-wave theory can not account for. It is therefore important ... -
Normally incident ultrasonic beam transmission through a water-embedded steel plate as a function of ka-number

Norovirus in Pacific Oysters : Insights into Molecular Viability Assays and Mitigation Strategies to Improve Food Safety
(Doctoral thesis, 2022-11-21)Som en av de vanligste årsakene til gastroenteritt, har norovirus (NoV) vært en belastning for pasienter, helsemyndigheter og samfunnet over hele verden. Patogenet overføres gjennom inntak av infektive viruspartikler. Mange ... -
North African wetland lakes: characterization of nine sites included in the CASSARINA Project
(Peer reviewed; Journal article, 2001)Exploitation of land and water resources has increased rapidly in North Africa during the 20th century, paralleling regional population growth. As part of the CASSARINA Project (see Flower, 2001), the environmental status ... -
North Atlantic 20th century multidecadal variability in coupled climate models: sea surface temperature and ocean overturning circulation
(Peer reviewed; Journal article, 2011-06-06)Output from a total of 24 state-of-the-art Atmosphere-Ocean General Circulation Models is analyzed. The models were integrated with observed forcing for the period 1850–2000 as part of the Intergovernmental Panel on Climate ... -
North Atlantic Modulation of Interdecadal Variations in Hot Drought Events over Northeastern China
(Journal article; Peer reviewed, 2020)Based on the long-term reanalysis datasets and the multivariate copula method, this study reveals that the frequency of summer hot drought events (SHDEs) over northeastern China (NEC) shows interdecadal variations during ... -
North Atlantic multi-decadal variability - mechanisms and predictability
(World Scientific Series on Asia-Pacific Weather and Climate, Chapter; Peer reviewed, 2015-10)The North Atlantic Ocean undergoes pronounced basin-wide, multi-decadal variations. The corresponding fluctuations in sea surface temperature (SST) have become known as the Atlantic Multi-decadal Oscillation (AMO) or ... -
North Atlantic multidecadal variability in coupled climate models - Mechanisms and responses
(Doctoral thesis, 2011-05-06)Global atmosphere-ocean general circulation models have been used to investigate mechanisms controlling the North Atlantic low-frequency variability, with the focus on the Atlantic Meridional Overturning Circulation, the ... -
North Atlantic ocean circulation and decadal sea level change during the Altimetry era
(Peer reviewed; Journal article, 2019-01-31)Regional sea-level rise is characterized by decadal acceleration and deceleration periods that typically stem from oceanic climate variability. Here, we investigate decadal sea-level trends during the altimetry era and pin ... -
The North Atlantic Oscillation and greenhouse-gas forcing
(Peer reviewed; Journal article, 2005-02-17)The results of 12 coupled climate models participating in the Coupled Model Intercomparison Project (CMIP2) are compared together with observational data in order to investigate: 1) How the current generation of climate ... -
North Atlantic Oscillation in winter is largely insensitive to autumn Barents-Kara sea ice variability
(Journal article; Peer reviewed, 2021)Arctic sea ice extent in autumn is significantly correlated with the winter North Atlantic Oscillation (NAO) in the satellite era. However, questions about the robustness and reproducibility of the relationship persist. ... -
North Atlantic storm track changes during the Last Glacial Maximum recorded by Alpine speleothems
(Peer reviewed; Journal article, 2015-02-27)The European Alps are an effective barrier for meridional moisture transport and are thus uniquely placed to record shifts in the North Atlantic storm track pattern associated with the waxing and waning of Late-Pleistocene ... -
North Atlantic surface ocean warming and salinization in response to middle Eocene greenhouse warming
(Journal article; Peer reviewed, 2023)Quantitative reconstructions of hydrological change during ancient greenhouse warming events provide valuable insight into warmer-than-modern hydrological cycles but are limited by paleoclimate proxy uncertainties. We ... -
The North Atlantic waveguide and downstream impact experiment
(Peer reviewed; Journal article, 2018)The North Atlantic Waveguide and Downstream Impact Experiment (NAWDEX) explored the impact of diabatic processes on disturbances of the jet stream and their influence on downstream high-impact weather through the deployment ... -
North Atlantic weather regimes in δ18O of winter precipitation: isotopic fingerprint of the response in the atmospheric circulation after volcanic eruptions
(Journal article; Peer reviewed, 2019)Equatorial volcanic eruptions are known to impact the atmospheric circulation on seasonal time scales through a strengthening of the stratospheric zonal winds followed by dynamic ocean-atmosphere coupling. This emerges as ... -
North Sea circulation: Atlantic inflow and its destination
(Peer reviewed; Journal article, 2006-12-22)This study investigates the Atlantic inflow to the North Sea; its variabil- ity, pathways and destination. Results from a numerical model show that the variability of Atlantic inflow is dependent on the inflow location. ... -
North-south asymmetries in cold plasma density in the magnetotail lobes: Cluster observations
(Peer reviewed; Journal article, 2017-01)In this paper, we present observations of cold (0–70 eV) plasma density in the magnetotail lobes. The observations and results are based on 16 years of Cluster observation of spacecraft potential measurements converted ... -
A North-South Contrast of Subsurface Salinity Anomalies in the Northwestern Pacific From 2002 to 2013
(Peer reviewed; Journal article, 2019-03)This paper finds a north‐south contrast of subsurface salinity trend during 2002–2013 in the northwestern Pacific. Both Argo float data and long‐term repeat hydrographic measurements along the 137°E section show that ... -
Northeast Arctic Cod and Prey Match-Mismatch in a High-Latitude Spring-Bloom System
(Journal article; Peer reviewed, 2021)By combining an ocean model, a nutrient-phytoplankton-zooplankton-detritus-model and an individual-based model for early life stages of Northeast Arctic cod we systematically investigate food limitations and growth performance ... -
