    • Advancing Ocean Observation with an AI-driven Mobile Robotic Explorer 

      Saad, Aya; Stahl, Annette; Våge, Andreas; Davies, Emlyn John; Nordam, Tor; Aberle-Malzahn, Nicole; Ludvigsen, Martin; Johnsen, Geir; Sousa, João; Rajan, Kanna (Journal article; Peer reviewed, 2020)
      Rapid assessment and enhanced knowledge of plankton communities and their structure in the productive upper water column is of crucial importance to understand the impact of the changing climate on upper ocean processes. ...

    • Atlantic cod (Gadus morhua) embryos are highly sensitive to short-term 3,4-dichloroaniline exposure 

      Hansen, Bjørn Henrik; Farkas, Julia; Piarulli, Stefania; Vicario, Silvia; Kvæstad, Bjarne; Williamson, David Roddan; Sørensen, Lisbet; Davies, Emlyn John; Nordtug, Trond (Peer reviewed; Journal article, 2021)
      3,4-dichloroaniline (3,4-DCA) is one of the most widely produced anilines world-wide, used in plastic packaging, fabrics, pharmaceuticals, pesticides, dyes and paints as well as being a degradation product of several ...

    • Biodegradation of Dispersed Oil in natural Seawaters from Western Greenland and a Norwegian fjord 

      Brakstad, Odd Gunnar; Davies, Emlyn John; Ribicic, Deni; Winkler, Anika; Brönner, Ute; Netzer, Roman (Journal article; Peer reviewed, 2018)
      With increasing oil exploration, production and transportation in the Arctic, predictions of the fate of spilled oil become important, including oil compound biodegradation. The use of chemical dispersants may result in ...

    • Contrasting phytoplankton-zooplankton distributions observed through autonomous platforms, in-situ optical sensors and discrete sampling 

      Fragoso, Glaucia Moreira; Davies, Emlyn John; Fossum, Trygve Olav; Ullgren, Jenny; Majaneva, Sanna; Aberle-Malzahn, Nicole; Ludvigsen, Martin; Johnsen, Geir (Peer reviewed; Journal article, 2022)
      Plankton distributions are remarkably ‘patchy’ in the ocean. In this study, we investigated the contrasting phytoplankton-zooplankton distributions in relation to wind mixing events in waters around a biodiversity-rich ...

    • Effects of mine tailing exposure on early life stages of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) 

      Farkas, Julia; Nordtug, Trond; Svendheim, Linn Hjelmeland; D Amico, Elettra; Davies, Emlyn John; Ciesielski, Tomasz Maciej; Jensen, Bjørn Munro; Kristensen, Torstein; Olsvik, Pål Asgeir; Hansen, Bjørn Henrik (Peer reviewed; Journal article, 2021)
      Mining and processing of minerals produce large quantities of tailings as waste. Some countries, including Norway, allow disposal of mine tailings in the sea. In this study we investigated the impacts of tailings from a ...

    • A flow-through imaging system for automated measurement of ichthyoplankton 

      Williamson, David Roddan; Nordtug, Trond; Leirvik, Frode; Kvæstad, Bjarne; Hansen, Bjørn Henrik; Ludvigsen, Martin; Davies, Emlyn John (Peer reviewed; Journal article, 2022)
      Microscopic imaging and morphometric measurement of fish embryos and larvae is essential in environmental monitoring of fish populations and to evaluate larvae development in aquaculture. Traditional microscopy methods ...

    • High-resolution numerical modelling of a marine mine tailings discharge in Western Norway 

      Nepstad, Raymond; Muñoz, Maria Liste; Alver, Morten; Nordam, Tor; Davies, Emlyn John; Glette, Tormod (Peer reviewed; Journal article, 2020)
      Waste from mining operations includes mine tailings, a slurry of fine-grained mineral particles and processing chemicals that remains after the desired compounds have been extracted from the ore. In some cases, the method ...

    • Physical controls on phytoplankton size structure, photophysiology and suspended particles in a Norwegian biological hotspot 

      Fragoso, Glaucia Moreira; Davies, Emlyn John; Ellingsen, Ingrid H.; Chauton, Matilde Skogen; Fossum, Trygve Olav; Ludvigsen, Martin; Steinhovden, Kristine; Rajan, Kanna; Johnsen, Geir (Peer reviewed; Journal article, 2019)
      The impact of the physical environment and phytoplankton size on particle types (zooplankton, biogenic matter or phytodetritus) in the water column is poorly understood. Here, we investigate how hydrography (e.g. water ...

    • Pre-reduction of United Manganese of Kalahari Ore in CO/CO<inf>2</inf>, H<inf>2</inf>/H<inf>2</inf>O, and H<inf>2</inf> Atmospheres 

      Davies, Emlyn John; Tangstad, Merete; Schanche, Trygve Lindahl; du Preez, Preez (Peer reviewed; Journal article, 2023)
      The incorporation of hydrogen, which is a relatively unexplored reductant used during ferromanganese (FeMn) production, is an attractive approach to lessen atmospheric gaseous carbon release. The influence of hydrogen on ...

    • Toward adaptive robotic sampling of phytoplankton in the coastal ocean 

      Fossum, Trygve Olav; Fragoso, Glaucia Moreira; Davies, Emlyn John; Ullgren, Jenny; Mendes, Renato; Johnsen, Geir; Ellingsen, Ingrid H.; Eidsvik, Jo; Ludvigsen, Martin; Rajan, Kanna (Journal article; Peer reviewed, 2019)
      Currents, wind, bathymetry, and freshwater runoff are some of the factors that make coastal waters heterogeneous, patchy, and scientifically interesting—where it is challenging to resolve the spatiotemporal variation within ...
