The Barents Sea shelf has been experienced extensive uplift and erosion in the Cenozoic. However, the pre-glacial erosion has been so far less constrained in comparison to the glacial erosion. This paper aims to better understand the early–middle Cenozoic erosion in the western Barents Sea and the late Cenozoic erosion in the northern Barents Sea by using the mass-balance approach. The study utilizes ...

Cold seeps are chemosynthetic habitats found in both deep sea and shallow ocean-shelves worldwide, including the polar regions. At seeps, hydrocarbons, sulfide, and other reduced compounds emerge from the seafloor, providing energy to fuel chemoautotrophic production. Microbial assemblages, supported by the oxidation and reduction of gases and fluids, form the base of a food web composing unique and ...

The thesis investigates imaging in the vertical direction of different types of ice in the arctic using synthetic aperture radar (SAR) tomography and SAR interferometry. In the first part, the magnitude and the positions of the dominant scattering contributions within snow covered fjord and lake ice layers are effectively identified by using a very high resolution ground-based tomographic SAR system. ...

The memory properties in paleoclimate temperature records based on model simulations and proxy-reconstructions have been investigated, to find out if these records exhibit long-range memory in a similar manner as many instrumental temperature records. On time scales from years to centuries and even millennia, long-range memory is identified in the paleoclimate records using a toolbox of statistical ...

An ever-increasing number of web applications are providing open services to a wide range of applications. Whilst traditional centralized approaches to services orchestration are successful for enterprise service-oriented systems, they are subject to serious limitations for orchestrating the wider range of open services. Dealing with these limitations calls for decentralized approaches. However, ...

In recent years, first-row metallocorroles have provided some of the most instructive examples of noninnocent ligands. This thesis presents a study of some 50 iron, manganese, and cobalt corrole complexes with different axial ligands (including approximately 30 new compounds and 6 new X-ray structures) with emphasis on their noninnocent/innocent character. UV-vis spectroscopy has for some time ...

A ship travelling in sub-freezing conditions may encounter sea spray, rain, fog or snow freezing onto various parts of it. Such ship icing is a well-known threat for those individuals who have served on ships operating in a cold marine climate. As de-icing techniques may be energy consuming, accurate prediction of icing is also desirable from a financial point of view. Throughout the last 60 years ...

The main focus of this thesis is the diagnostics of ion beams in helicon plasma devices with expanding magnetic field, and running in an inductive mode. These ion beams are closely connected to the concept of current-free double layers (CFDL). We started by investigating how to best interpret the measurements from a Retarding Field Energy Analyzer (RFEA) through 3-dimensional particle-in-cell ...

Antibiotic resistance is a topic that concerns everyone, and by 2050 deaths due to antibiotic resistant bacteria may surpass number of deaths due to cancer. The OXA-class of antibiotic resistance enzymes is a formidable threat, but has not received the same attention as other resistance enzymes. The goal of the project was to understand antibiotic resistance enzymes at an atomic scale and to develop ...

With the accelerated advances in sequencing technology the last decade, the field of metagenomics has progressed immensely. Sampling and sequencing of metagenomic data is now prevalent, and publicly available data sets from mundane soil and water environments to exotic niche habitats such as geothermal hot springs are readily available through sequence data repositories such as the European Nucleotide ...
