Algal colonization of young arctic sea ice in spring
Kauko, Hanna Maria; Olsen, Lasse Mork; Duarte, Pedro; Peeken, Ilka; Granskog, Mats A.; Johnsen, Geir; Fernández-Méndez, Mar; Pavlov, Alexey; Mundy, Christopher John; Assmy, Philipp (Journal article; Peer reviewed, 2018)The importance of newly formed sea ice in spring is likely to increase with formation of leads in a more dynamic Arctic icescape. We followed the ice algal species succession in young ice (≤ 0.27 m) in spring at high ... -
Discharge of nutrient wastes from salmon farms: environmental effects, and potential for integrated multi-trophic aquaculture
Wang, Xinxin; Olsen, Lasse Mork; Reitan, Kjell Inge; Olsen, Yngvar (Journal article; Peer reviewed, 2012)We quantified release rates of carbon (C), nitrogen (N) and phosphorus (P) waste from Norwegian salmon farms in 2009 in order to evaluate the theoretical environmental influence on surrounding waters and the potential for ... -
Interactions between marine osmo- and phagotrophs in different physicochemical environments
Olsen, Lasse Mork (Doktoravhandlinger ved NTNU, 1503-8181; 2005:124, Doctoral thesis, 2005)The interaction between the marine phototrophic dinoflagellate Prorocentrum minimum and associated bacteria was studied in different physico-chemical environments in batch cultures. In stagnant cultures the dinoflagellates ... -

The aim of MOSAiC ... -
Responses in the bacterial community structure to waste nutrients from aquaculture: an in situ microcosm experiment in a Chilean fjord
Olsen, Lasse Mork; Hernandez, Klaudia; Ardelan, Murat Van; Iriarte, Jose Luis; Bizsel, Can; Olsen, Yngvar (Journal article; Peer reviewed, 2017)Chilean salmon farms release inorganic nutrients excreted by the fish into the surrounding water in Patagonian fjords. The objective of this experiment from the Comau Fjord (42.2° S) in southern Chile was to study how ... -
Responses in the microbial food web to increased rates of nutrient supply in a southern Chilean fjord: Possible implications of cage aquaculture

(Journal article; Peer reviewed, 2017)Large changes in the sea ice regime of the Arctic Ocean have occurred over the last decades justifying the development of models to forecast sea ice physics and biogeochemistry. The main goal of this study is to evaluate ... -
Virkningen av økte næringssaltutslipp fra akvakultur på strukturen i planteplanktonsamfunnet
Løken, Maren (Master thesis, 2013)Et mesokosmeforsøk ble gjennomført over 20 dager i Hopavågen, Sør-Trøndelag. Forsøket ble startet under en typisk sensommer med resirkulerte næringsstoffer i et stratifisert vannlag (~10 m) og dominans av dinoflagellater ...
