On the use of the HUGIN 1000 HUS Autonomous Underwater Vehicle for high resolution zooplankton measurements
This paper evaluates and tests the HUGIN 1000 HUS AUV as a carrier platform for the Laser Optical Plankton Counter (LOPC). The LOPC was mounted outside on top of the carrier platform, and the tests confirm that this concept did not create turbulence and zooplankton avoidance. A negligible velocity difference between the flow passing through the sampling tube and the AUV speed was detected. The abundance recorded by the LOPC onboard HUGIN 1000 HUS was within the same order of magnitude compared to the zooplankton abundance from traditional net-based measurements. Our results showed zooplankton abundance in the range of 70 to 180 individuals m-3, while other, traditional net-based measurements have indicated 27 - 332 individuals m-3 from the same area and same depth layer. Note that these numbers are minimum and maximum values observed from a vast number of samples. The mean is approximately 200 individuals m-3. The results provide new and unique high-resolution biological data of deep-water copepod communities. The application of AUVs in marine ecological research introduces advanced methodology with potential to address new scientific questions in deep water habitats.

Innovation and commercialization potential of university-developed arctic ice-tethered platforms. A case study of research-based technology Agwu, Ukeje Jacob; Logvinovskaya, Anna; Phetchpinkaew, Gorn (Master thesis; Mastergradsoppgave, 2017-05-31)The Arctic is a region which is rapidly opening up for business opportunities. However, research has been abundant here for a long time. With this situation comes the avenue to transition technology used in the region from research to commercial purposes. In this thesis, a business case is developed to show the commercial potential of research-based technology. The case technology was developed by ...
Marin forsøpling. Hvilke regler gjelder med formål å forhindre primærmikroplastforsøpling i norske kyst-og havområder Slungård, Andrea Øiahals (Master thesis; Mastergradsoppgave, 2016-05-03)Masteroppgaven omhandler primær mikroplastforsøpling som følge av norsk bruk eller virksomhet og tar utgangspunkt i forsøplingskildene av primær mikroplast som er kosmetikk, gummigranulat fra idrettsbaner og utilsiktet utslipp fra plastindustrien. Marin forsøpling, herunder primær mikroplastforsøpling betegnes om de bearbeidede og prosesserte faste stoffer som havner i kyst og havområdene Primær ...
Aniceto, Ana Sofia; Biuw, Martin; Lindstrøm, Ulf; Solbø, Stian; Broms, Fredrik Björn; Carroll, JoLynn (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-08)Unmanned aerial vehicles (UAVs) are increasingly being recognized as potentially useful for detection of marine mammals in their natural habitats, but an important consideration is the associated uncertainties in animal detection. We present a study based on field trials using UAVs to carry out image‐based monitoring of cetaceans in two fjords in northern Norway. We conducted 12 missions to assess ...
