Beyond the storm season: The polyrhythms of coastal hazardscapes on the Kū aotunu Peninsula
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-17)In this paper, we develop an account of engaged practice of coastal conservation groups with seasonalities on the Coromandel Peninsula in New Zealand, focusing particularly on the polyrhythmicity of change in its coastal hazardscape. While the hazardousness of a place has often been considered in static terms, we wish here to draw attention to its complex temporalities and highly seasonal nature. ... -
Marine Operations in the Norwegian Sea and the Ice-Free Part of the Barents Sea with Emphasis on Polar Low Pressures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-18)The Arctic Seas are attractive for shipping, fisheries, and other marine activities due to the abundant resources of the Arctic. The shrinking ice cover allows for the opening of activities in increasingly larger areas of the Arctic. This paper evaluates the possibility of executing all-year complex marine activities, here termed “marine operations”, in the Norwegian Sea and the icefree part of ... -
Years matter: the role of memory and place attachment in remote Nordic areas facing natural hazards
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-05)Remembrance, commemoration, and specific dates play an important role in many societies and cultures. They can be about positively connotated events with societal impacts, such as reunifications or the gaining of independence, but also disastrous or other devastating events on a national or international scale. In disaster risk areas, there are various ways such events are addressed. While for some ... -
A Bayesian network model for estimating the combined risk in Northeast Passage escort operations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-12-02)Escort and convoy operations are commonly employed and highly effective strategies in the Arctic, particularly when ship navigating independently becomes challenging due to adverse ice conditions. Nonetheless, these operations are also among the riskiest, given their potential to lead to collisions between ships and icebreakers, as well as ships besetting in ice. Consequently, a robust estimation ... -
The challenges of the increasing institutionalization of climate security
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-25)A rapid and widespread institutionalization of climate security is underway, led by powerful states and international organizations. Recognition of the climate crisis by security actors as a serious threat to humanity is long overdue, but it is imperative that this institutionalization is critically scrutinized. This commentary highlights specific dangers that accompany the institutional mainstreaming ... -
Anticipating climate risk in Norwegian municipalities
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-11)Climate change is increasingly being coupled to extreme weather and climate events, with an observed increase in intensity and occurrence of climate-related events. Norway is no exception. Though generally considered quite resilient to climate risk, with favorable conditions for adapting on a national level, studies point to regional and local differences. Applying a mixed methods approach we ... -
Singular Value Decomposition-based Multiple Model Approach towards Developing Digital Twin Applications in Ship Performance Prediction
(Chapter; Bokkapittel, 2024)Representing the entire operational range of an ocean-going vessel with linear equations is often a formidable task. In this research study, a datadriven localized model is presented for ship performance prediction as a part of the digital twin development. For this purpose, different operational conditions of the vessel, i.e., data clusters, are identified using the Gaussian Mixture Models (GMM) ... -
On Statistical Features of Ice Loads on Fixed and Floating Offshore Structures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-08-22)Apart from the mechanisms of ice structure interactions under various scenarios of sea ice conditions and structural configurations, the selection of probabilistic models is crucial in order to cope with the loading uncertainty. Sea ice is the primary contributor to design loads in cold regions. In many cases, ice loads present the highest magnitude. In recent years, the probabilistic study of ice ... -
Predicting the Performance of Ensemble Classification Using Conditional Joint Probability
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-08-21)In many machine learning applications, there are many scenarios when performance is not satisfactory by single classifiers. In this case, an ensemble classification is constructed using several weak base learners to achieve satisfactory performance. Unluckily, the construction of the ensemble classification is empirical, i.e., to try an ensemble classification and if performance is not ... -
Assessing climate-induced risks to urban railway infrastructure
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-14)Climate change and its severe impacts pose a number of challenges to transport infrastructure, particularly railway infrastructure, requiring immediate action. A railway system is a linear distributed asset passing different geographical locations and exposed to heterogeneous vulnerabilities under diverse environmental conditions. Furthermore, most of the railway infrastructure assets were designed ... -
