    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-05)
      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 calcium carbonate (CaCO3) processing plant on early live stages of haddock (<i>Melanogrammus aeglefinus</i>) and Atlantic cod (<i>Gadus morhua</i>). Fish eggs (3 days post fertilisation; ...

    • Estimating Surface Concentrations of Calanus finmarchicus Using Standardised Satellite-Derived Enhanced RGB Imagery 

      McCarry, Cait L.; Basedow, Sünnje Linnéa; Davies, Emlyn John; McKee, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-08)
      Calanus finmarchicus is a keystone zooplankton species that is commercially harvested and is critical in sustaining many important fisheries in the North Atlantic. However, due to their patchy population distributions, they are notoriously difficult to map using traditional ship-based techniques. This study involves the use of a combined approach of standardized ocean colour imagery and radiative ...

    • The hidden influence of large particles on ocean colour 

      Davies, Emlyn John; Basedow, Sünnje Linnéa; McKee, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-17)
      Optical constituents in the ocean are often categorized as water, phytoplankton, sediments and dissolved matter. However, the optical properties of seawater are influenced, to some degree, by scattering and absorption by all particles in the water column. Here we assess the relevant size ranges for determining the optical properties of the ocean. We present a theoretical basis supporting the hypothesis ...
