    • Isoscape Models of the Southern Ocean: Predicting Spatial and Temporal Variability in Carbon and Nitrogen Isotope Compositions of Particulate Organic Matter 

      St. John Glew, Katie; Espinasse, Boris; Hunt, Brian P. V.; Pakhomov, Evgeny A.; Bury, Sarah J.; Pinkerton, Matt; Nodder, Scott D.; Gutiérrez-Rodríguez, Andres; Safi, Karl; Brown, Julie C. S.; Graham, Laura; Dunbar, Robert; Mucciarone, David A.; Magozzi, Sarah; Somes, Chris; Trueman, Clive N. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-30)
      Polar marine ecosystems are particularly vulnerable to the effects of climate change. Warming temperatures, freshening seawater, and disruption to sea-ice formation potentially all have cascading effects on food webs. New approaches are needed to better understand spatiotemporal interactions among biogeochemical processes at the base of Southern Ocean food webs. In marine systems, isoscapes (models ...

    • Pelagic food web structure in high nutrient low chlorophyll (HNLC) and naturally iron fertilized waters in the Kerguelen Islands region, Southern Ocean 

      Hunt, Brian P. V.; Espinasse, Boris Dristan; Pakhomov, Evgeny A.; Cherel, Yves; Cotté, Cédric; Delegrange, Alice; Henschke, Natasha (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-19)
      The Kerguelen Plateau is a region of natural iron fertilization in the Southern Ocean, within the typically iron limited High Nutrient Low Chlorophyll (HNLC) waters of the eastward flowing Antarctic Circumpolar Current. Between 26 February and 19 March 2018, the MOBYDICK expedition investigated pelagic ecosystem dynamics in the Kerguelen Island region on the northern plateau during the post-phytoplankton ...

    • The role of water mass advection in staging of the Southern Ocean Salpa thompsoni populations 

      Henschke, Natasha; Espinasse, Boris Dristan; Stock, Charles A.; Liu, Xiao; Barrier, Nicolas; Pakhomov, Evgeny A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-01)
      Salpa thompsoni is an important grazer in the Southern Ocean. Their abundance in the western Antarctic Peninsula is highly variable, varying by up to 5000-fold inter-annually. Here, we use a particle-tracking model to simulate the potential dispersal of salp populations from a source location in the Antarctic Circumpolar Current (ACC) to the Palmer Long Term Ecological Research (PAL LTER) study ...
