• A continent-wide search for Antarctic petrel breeding sites with satellite remote sensing 

      Schwaller, Matthew R.; Lynch, Heather J; Tarroux, Arnaud; Prehn, Brandon (Journal article; Peer reviewed, 2018)
      The Antarctic petrel (Thalassoica antarctica) has been identified as a key species for monitoring the status and health of the Southern Ocean and Antarctic ecosystems. Breeding colonies of the Antarctic petrel are often ...

    • An artificial intelligence approach to remotely assess pale lichen biomass 

      Erlandsson, Rasmus Ingel; Bjerke, Jarle W.; Finne, Eirik Aasmo; Myneni, Ranga B.; Piao, Shilong; Wang, Xuhui; Virtanen, Tarmo; Räsänen, Aleksi; Kumpula, Timo; Kolari, Tiina H.M.; Tahvanainen, Teemu; Tømmervik, Hans (Peer reviewed; Journal article, 2022)
      Although generally given little attention in vegetation studies, ground-dwelling (terricolous) lichens are major contributors to overall carbon and nitrogen cycling, albedo, biodiversity and biomass in many high-latitude ...
    • Development of new metrics to assess and quantify climatic drivers of Extreme event driven Arctic browning 

      Treharne, Rachael; Bjerke, Jarle W.; Tømmervik, Hans; Phoenix, Gareth H. (Journal article, 2020)
      Rapid climate change in Arctic regions is resulting in more frequent extreme climatic events. These can cause large-scale vegetation damage, and are therefore among key drivers of declines in biomass and productivity (or ...
    • Estimating lichen volume and reindeer winter pasture quality from Landsat imagery 

      Falldorf, Tobias; Strand, Olav; Panzacchi, Manuela; Tømmervik, Hans (Peer reviewed; Journal article, 2014)
      Reindeer and caribou are keystone species in the circumpolar region, and rely on lichens as their main winter forage to survive in some of the most extreme environments on Earth. Lichen mats, however, can be heavily ...
    • Hyperlocal mapping of urban air temperature using remote sensing and crowdsourced weather data 

      Venter, Alexander Samuel; Brousse, Oscar; Esau, Igor; Meier, Fred (Journal article, 2020)
      The impacts of climate change such as extreme heat waves are exacerbated in cities where most of the world's population live. Quantifying urbanization impacts on ambient air temperatures (Tair) has relevance for human ...
