Interannual variability and ventilation timescales in the ocean cavity beneath Filchner-Ronne Ice Shelf, Antarctica
(Peer reviewed; Journal article, 2004-04-20)Multiyear time series of ocean current and temperatures from beneath Filchner-Ronne Ice Shelf, Antarctica, demonstrate both seasonal and interannual variability. The seasonal signal is visible at all measurement sites, ... -
Interannual variability in the wintertime air–sea flux of carbon dioxide in the northern North Atlantic, 1981–2001
(Peer reviewed; Journal article, 2003)Gridded fields of sea surface temperature (SST), sea level pressure (SLP), and wind speed were used in combination with data for the atmospheric mole fraction of CO2 and an empirical relationship between measured values ... -
Interannual variability of air temperature inversions in ice-free area of northern James Ross Island, Antarctica
(Journal article; Peer reviewed, 2022)Air temperature inversions are common features in Antarctica, especially in the interior where they are observed nearly year-round. Large temporal variability of air temperature inversion incidence is typical for the coastal ... -
Interannual variations of freshwater content in Hornsund
(Master thesis, 2015-05-04)Salinity measurements have been used to calculate the freshwater content in Hornsund for the years 2001 to 2014. In 2011 there was significantly higher freshwater content in the fjord, compared to the other years, with a ... -
Intercomparison of initialization methods for seasonal-to-decadal climate predictions with the NorCPM
(Journal article; Peer reviewed, 2024)Initialization is essential for accurate seasonal-to-decadal (S2D) climate predictions. The initialization schemes used differ on the component initialized, the Data Assimilation method, or the technique. We compare five ... -
Intercomparison of Small Unmanned Aircraft System (sUAS) Measurements for Atmospheric Science during the LAPSE-RATE Campaign
(Peer reviewed; Journal article, 2019-05-10)Small unmanned aircraft systems (sUAS) are rapidly transforming atmospheric research. With the advancement of the development and application of these systems, improving knowledge of best practices for accurate measurement ... -
Interdecadal Changes in the Linkage Between North Pacific Oscillation During May and Northeast China Precipitation During Mid-Summer: The Influence of North Atlantic Oscillation
(Journal article; Peer reviewed, 2023)Many previous studies have documented the relationship between the North Pacific Oscillation (NPO) and the weather/climate of upstream and downstream regions. However, the stability of NPO precursor signals of East Asian ... -
Intermediate water from the Greenland Sea in the Faroe Bank Channel : spreading of released sulphur hexafluoride
(Journal article, 2005-02)The Faroe Bank Channel is the deepest passage for dense water leaving the Nordic Seas into the North Atlantic. The contribution to this part of the Greenland-Scotland Overflow by intermediate water from the Greenland Sea ... -
Intermittency of Arctic–mid-latitude teleconnections: stratospheric pathway between autumn sea ice and the winter North Atlantic Oscillation
(Journal article; Peer reviewed, 2020)There is an observed relationship linking Arctic sea ice conditions in autumn to mid-latitude weather the following winter. Of interest in this study is a hypothesized stratospheric pathway whereby reduced sea ice in the ... -
Intermittent Reduction in Ocean Heat Transport Into the Getz Ice Shelf Cavity During Strong Wind Events
(Journal article; Peer reviewed, 2021)The flow of warm water toward the western Getz Ice Shelf along the Siple Trough, West Antarctica, is intermittently disrupted during short events of Winter Water deepening. Here we show, using mooring records, that these ... -
Intraseasonal and synoptic modulation of diurnal surface solar radiation over Reunion island in the South-West Indian Ocean
(Journal article; Peer reviewed, 2023)Understanding the space-time variability of Surface Solar Radiation (SSR) is mandatory for the prediction and, eventually, the skillful forecasting of photovoltaic energy production. This paper addresses the modulation of ... -
Introduction to focus issue: Synchronization in large networks and continuous media - Data, models, and supermodels
(Peer reviewed; Journal article, 2017)The synchronization of loosely coupled chaotic systems has increasingly found applications to large networks of differential equations and to models of continuous media. These applications are at the core of the present ... -

Investigating genesis and early development of Arctic cyclones using an isentropic analysis
(Master thesis, 2024-06-10)Cyclones are frequently found in the Arctic and can have wide-ranging impacts on the region. Nevertheless, few studies have focused on the development of cyclones originating in the Arctic, in contrast to the extensively ... -
Investigating the Southern Ocean Biogeochemical Divide
(Master thesis, 2024-06-03)The Southern Ocean plays a crucial role in Earth's climate and biogeochemical (BGC) cycles due to its unique features, such as strong westerly winds, intense ocean circulation, and its high-latitude location. This study ... -
Investigating voltage ripple effects in PEM electrolysis: test protocol development and experimental characterisation
(Master thesis, 2024-08-01)PEM water electrolysis is a key technology for producing high-purity hydrogen with a compact design. However, the widespread adoption of PEM electrolysers faces challenges such as the high cost associated with the power ... -
An investigation into the dynamical and statistical properties of dominant ocean surface waves using close-range remote sensing
(Doctoral thesis, 2022-09-16)Denne avhandlingen er basert på forskningsresultat som behandler statistiske og dynamiske egenskaper av dominante vinddrevne overflatebølger i åpent hav. Med uttrykket dominante bølger refererer vi her til de største ... -
Investigation of gaseous ammonia for NOx control by SCR on an experimental basis
(Master thesis, 2016-08-15)My dissertation argues which of the two reducing agents, urea or pure ammonia, is better suited for reducing NOx emissions in Marine SCR applications. While the question might seem straight forward, there are several upsides ... -
Investigation of offshore wind turbine wakes by numerical modeling and full-scale measurements
