Distribution and Variation of the Trace Metal Iron in the Base of the Pelagic Marine Food Web: A Mesocosm Approach: Trace Metal in marine biology
(Master thesis, 2012)This study was part of the WAFOW project “Can waste emission from fish farms change the structure of marine food webs?” whose objective was to perform mesocosms experiment to simulate the ammonium enriched environment, ... -
Identification of Sources for Illegal Oil Spills by Using GC-MS (Gas Chromatography and Mass-Spectrometry) Databases and Multivariate Statistics
(Master thesis, 2011)Preparing a defensible oil spill fingerprinting is always challenging. Presently available well established method for this purpose is a univariate method by comparison of diagnostic ratio using repeatability limit as ... -
Investigation on the Experimental Determination of Crude Oil in the Faeces from the Marine Copepod Calanus finmarchicus.
(Master thesis, 2012)Oil spilled into the ocean is subjected to weathering processes which alter the spilled or discharged oil. Natural dispersion is a weathering process which removes oil from the sea surface by breaking the oil into droplets. ... -
Investigations on the Applicability of Membrane Introduction as a Sampling Technique for Oil in Air and Water with Flame Ionization Detector (FID) and Mass Spectrometry (MS) Detection
(Master thesis, 2012)During a membrane introduction (MI) analysis the analytes are separated from the bulk matrix (e.g. air or water) by a semi-permeable membrane and transported to the detector by a carrier gas (usually helium). The most ... -
Kartlegging og evaluering av miljøstatus i vannforekomster nær Statoils sandoljeprosjekt i Leismer (Alberta, Canada). Videreutvikling og utesting av en ny type passiv prøvetaker for metaller i naturlig vann.
(Master thesis, 2012)I denne oppgaven har det blitt utført en kartlegging og evaluering av miljøstatus i overflatevann rundt Statoils oljesandområde i Alberta, Canada. Det har blitt prøvetatt vann for oppløst og syreoppløst konsentrasjon av ... -
Kartlegging og overvåking av tungmetaller i oljesandområder
(Master thesis, 2011)I denne oppgaven har det blitt utført kartlegging av bakgrunnskonsentrasjoner av utvalgte grunnstoffer og andre viktige parametere (pH, DOC og TDN) i overflatevann rundt Statoils oljesandfelt Leismer i Alberta, Canada. ... -
Metaller og naturlig organisk materiale i arktiske elver på Svalbard
(Master thesis, 2012)I denne oppgaven har det blitt utført kartlegging av innhold av elementer og oppløst organisk karbon (DOC) i elvevann og skum i Bayelva og Londonelva, to arktiske elver med utløp i Kongsfjorden på Svalbard. Andre viktige ... -
The Effects of Macronutrient Enrichments (ammonium) on the Distribution of Four Bioactive Trace Metals (Cd, Mo, Ni, Cu) in Seawater and Planktonic Biomass.
(Master thesis, 2012)Environmental impacts of aquaculture can be widespread and serious, and one of the problems connected to this activity is the release of waste in the form of macronutrients. One important aspect is the potential of a shift ...
