Questions and hypotheses

Tripos arcticum

Questions addressed

  • Are there novel species not yet formally described? Which?
  • Are any species endemic for the Arctic, and what are their geographical distribution?
  • Under which environmental conditions do they occur?
  • How does the protist community composition vary through the seasons in the Atlantic Arctic Ocean?
  • Can we detect changes in species composition and distribution compared to the past 30 years or more? 
  • If so what are these changes, and what are possible consequences? 


  • Protist communities in the Arctic Ocean are unique, and include taxa endemic for the Arctic.
  • There are novel protist species that have not yet been formally described in the Arctic Ocean and sea ice.
  • The geographical distribution of selected protists in the Arctic Ocean has changed the last 30-100 years.
