Update on frequency decline of Northeast Pacific blue whale (Balaenoptera musculus) calls
(Peer reviewed; Journal article, 2022)Worldwide, the frequency (pitch) of blue whale (Balaenoptera musculus) calls has been decreasing since first recorded in the 1960s. This frequency decline occurs over annual and inter-annual timescales and has recently ... -
Update on GM canola crops as novel sources of omega‐3 fish oils
(Journal article; Peer reviewed, 2018)There is considerable interest in new sources of omega‐3 long‐chain (here defined as fatty acids ≥C20) polyunsaturated fatty acids (LC‐PUFA), specifically eicosapentaenoic acid (EPA; 20:5n‐3) and docosahexaenoic acid (DHA; ... -
Updated trends for atmospheric mercury in the Arctic: 1995–2018
(Journal article; Peer reviewed, 2022)The Arctic region forms a unique environment with specific physical, chemical, and biological processes affecting mercury (Hg) cycles and limited anthropogenic Hg sources. However, historic global emissions and long range ... -
Upgrading Marine Oils from Cod (Gadus morhua) On-Board the Deep-Sea Vessels—From Waste to Value
(Peer reviewed; Journal article, 2023)Significant amounts of marine raw material are lost on-board the deep-sea vessels due to fast quality degradation. Optimal on-board handling and processing strategies can upgrade these resources from waste to food ingredients ... -
Upgrading off-grades from the silicon process: Increasing the silicon yield from Elkem Thamshavn using mechanical or metallurgical separation
(Master thesis, 2011)The aim of the thesis is to produce high grade silicon from off-grade materials like sculls and process slags from Elkem Thamshavn. The methods investigated are dense medium separation, optical separation, flotation and ... -
Uptake and biological response to zinc by the Diatom Thalassiosira pseudonana
(Master thesis, 2012)The uptake and incorporation of zink by a Si-, Co- , and Zn starved Thalassiosira pseudonana culture was examined. Two experiments were conducted in which a pre-determined amount of a zinc sulfate solution and sodium ... -
Uptake and effects of microplastic particles in selected marine microalgae species; Oxyrrhis marina and Rhodomonas baltica
(Master thesis, 2017)It is estimated that large numbers of microplastics are present in the marine environment and their concentrations are expected to rise in a foreseeable future. Interactions, uptake, and excretion rates as well as effects ... -
