Facilitating microplastic quantification through the introduction of a cellulose dissolution step prior to oxidation: Proof-of-concept and demonstration using diverse samples from the Inner Oslofjord, Norway
(Journal article; Peer reviewed, 2020)Identifying and quantifying microplastic in marine samples can be facilitated by removing natural organic matter (NOM). Cellulosic material, like chitin, however, are a type of NOM that is resistant to chemical digestion, ... -
Factors affecting extreme rainfall events in the South Pacific
(Journal article; Peer reviewed, 2020)Extreme rainfall events in the South Pacific are widespread and affected by various factors on different time scales. We use daily rainfall data from 20 stations over the South Pacific to investigate the characteristics ... -
Factors controlling the total alkalinity in the Arabian Sea and Red Sea
(Master thesis, 2010-06-01)Based on data obtained during the Geochemical Ocean Section Study (GEOSECS) 1977, Mer Rouge (MEROU) 1982, and US Joint Global Ocean Flux (JGOFS) 1995 studies we have analyzed the processes controlling the total alkalinity ... -
Fair Winds and Following Seas Remotely: Modifying Perceptions of Fieldwork as a Requirement in Marine Science to Aid in Diversifying the Discipline
(Journal article; Peer reviewed, 2023) -
Faroe Bank Channel Overflow: Mesoscale Variability
(Peer reviewed; Journal article, 2011-11)The Faroe Bank Channel is the deepest connection through the Greenland–Scotland Ridge, where dense water formed north of the ridge flows southward over the sill crest, contributing to the formation of North Atlantic Deep ... -
Fast Liquid Chromatography Coupled with Tandem Mass Spectrometry for the Analysis of Vanillic and Syringic Acids in Ice Cores
(Journal article; Peer reviewed, 2022)The development of new analytical systems and the improvement of the existing ones to obtain high-resolution measurements of chemical markers in samples from ice cores, is one of the main challenges the paleoclimatic ... -
The fate of the Atlantic Water in the North Icelandic Irminger Current
(Master thesis, 2012-01-19)The fate of the Atlantic Water within the North Icelandic Irminger Current has long been questioned. The North Icelandic Irminger Current flows along the Icelandic shelf area to the west and north of Iceland, bringing warm ... -
Fate of Warm Pacific Water in the Arctic Basin
(Journal article; Peer reviewed, 2021)Pacific Summer Water (PSW) plays a critical role in the ecosystem of the western Arctic Ocean, impacting sea-ice melt and providing freshwater to the basin. Most of the water exits the Chukchi Sea shelf through Barrow ... -
Feature-Based Jet Variability in the Upper Troposphere
(Journal article; Peer reviewed, 2020)Jets in the upper troposphere constitute a cornerstone of both synoptic meteorology and climate dynamics, providing a direct link between weather and midlatitude climate variability. Conventionally, jet variability is often ... -
Fine scale distribution of precipitation in the Voss area
(Master thesis, 2015-06-05)The precipitation in Western Norway is strongly affected by its position in the mid latitude conveyor belt of synoptic systems. When the warm and moist air impinges on the complex mountainous terrain, large variabilities ... -
Fingerprint of Climate Change on Southern Ocean Carbon Storage
(Journal article; Peer reviewed, 2023)The Southern Ocean plays a critical role in the uptake, transport, and storage of carbon by the global oceans. It is the ocean's largest sink of CO2, yet it is also among the regions with the lowest storage of anthropogenic ... -
Finite Element Analysis of the fatigue strength of a big-end bolt
(Master thesis, 2017-06-23)This thesis investigates, with the use of finite element method, the stress formation in a big-end bolt during the power stroke in an IC piston engine. The method used is quasi-static analysis of the lower part of the ... -
A finite element method for simulating soft active non-shearable rods immersed in generalized Newtonian fluids
(Journal article; Peer reviewed, 2022)We propose a finite element method for simulating one-dimensional solid models with finite thickness and finite length that move and experience large deformations while immersed in generalized Newtonian fluids. The method ... -
First results of turbulence measurements in a wind park with the Small Unmanned Meteorological Observer SUMO
(Peer reviewed; Journal article, 2012-01)The Small Unmanned Meteorological Observer (SUMO), equipped with a miniaturized 5-hole probe for turbulent flow measurements with 100 Hz temporal resolution, has for the first time been operated in and around a wind farm. ... -
A flexible device to produce a gas stream with a precisely controlled water vapour mixing ratio and isotope composition based on microdrop dispensing technology
(Journal article; Peer reviewed, 2023)Here we describe a versatile device to produce a gas stream with a precisely controlled water vapour mixing ratio and stable water isotope composition based on microdrop dispensing technology. To produce a moist ... -
FLIIMP - a community software for the processing, calibration, and reporting of liquid water isotope measurements on cavity-ring down spectrometers
(Journal article; Peer reviewed, 2023)Precise and accurate measurements of the stable isotope composition from precipitation, land ice, runoff, and oceans provide critical information on Earth's water cycle. The analysis, post-processing, and calibration of ... -
FLOHOF 2007: an overview of the mesoscale meteorological field campaign at Hofsjökull, Central Iceland
