    • Increasing depth distribution of Arctic kelp with increasing number of open water days with light 

      Castro de la Guardia, Laura; Filbee-Dexter, Karen; Reimer, Jillian; MacGregor, Kathleen A.; Garrido, Ignacio; Singh, Rakesh K.; Bélanger, Simon; Konar, Brenda; Iken, Katrin; Johnson, Ladd E.; Archambault, Philippe; Sejr, Mikael K.; Søreide, Janne; Mundy, C.J. (Peer reviewed; Journal article, 2023)
      Kelps are a dominant macrophyte group and primary producer in Arctic nearshore waters that provide significant services to the coastal ecosystem. The quantification of these services in the Arctic is constrained, however, ...

    • Kelp carbon sink potential decreases with warming due to accelerating decomposition 

      Filbee-Dexter, Karen; Feehan, Colette J.; Smale, Dan A.; Krumhansl, Kira A.; Augustine, Skye; de Bettignies, Florian; Burrows, Michael T.; Byrnes, Jarrett E.K.; Campbell, Jillian; Davoult, Dominique; Dunton, Kenneth H.; Franco, Joao N.; Garrido, Ignacio; Grace, Sean P.; Hancke, Kasper; Johnson, Ladd E.; Konar, Brenda; Moore, Pippa J.; Norderhaug, Kjell Magnus; O'Dell, Alasdair; Pedersen, Morten F.; Salomon, Anne K.; Sousa-Pinto, Isabel; Tiegs, Scott; Yiu, Dara; Wernberg, Thomas (Peer reviewed; Journal article, 2022)
      Cycling of organic carbon in the ocean has the potential to mitigate or exacerbate global climate change, but major questions remain about the environmental controls on organic carbon flux in the coastal zone. Here, we ...

    • Kelp in the Eastern Canadian Arctic: Current and Future Predictions of Habitat Suitability and Cover 

      Goldsmit, Jesica; Schlegel, Robert W.; Filbee-Dexter, Karen; MacGregor, Kathleen A.; Johnson, Ladd E.; Mundy, Christopher J.; Savoie, Amanda M.; McKindsey, Christopher W.; Howland, Kimberly L.; Archambault, Philippe (Peer reviewed; Journal article, 2021)
      Climate change is transforming marine ecosystems through the expansion and contraction of species’ ranges. Sea ice loss and warming temperatures are expected to expand habitat availability for macroalgae along long stretches ...

    • Sea Ice and Substratum Shape Extensive Kelp Forests in the Canadian Arctic 

      Filbee-Dexter, Karen; MacGregor, Kathleen A.; Lavoie, Camille; Garrido, Ignacio; Goldsmit, Jesica; Castro de la Guardia, Laura; Howland, Kimberly L.; Johnson, Ladd E.; Konar, Brenda; McKindsey, Christopher W.; Mundy, Christopher J.; Schlegel, Robert W.; Archambault, Philippe (Peer reviewed; Journal article, 2022)
      The coastal zone of the Canadian Arctic represents 10% of the world’s coastline and is one of the most rapidly changing marine regions on the planet. To predict the consequences of these environmental changes, a better ...
