 note = {Microcosm experiments were conducted to study the relative survival of two Escherichia coli strains in the Kongsfjorden water during 2017 Arctic summer. One of the E. coli strain was from the migratory bird Branta leucopis (Barnacle goose), to represent the allochthonous E. coli from migratory bird community, and the other strain was from the reindeer (Rangifer tarandus), which is a native animal. We observed that both B. leucopis and R. tarandus feed on the tundra and the faecal indicator bacteria (E. coli) in the faecal entrapments find their way to the Kongsfjorden along with the melt water from tundra during the Arctic summer. Survival is evaluated in terms of the self-contained biotic factors in the fjord water, chemical composition of the fjord water and solar radiation impinging on the water during Arctic summer. Results revealed that biotic factors and solar radiation were most effective in the removal of E. coli from the Kongsfjorden water, while chemical composition of the fjord water supported extended survival of E. coli. T90 (time required for the removal of 90% of the cells) was reached in less than 24 h in the test solutions to study the effect of biotic factors while T90 as a function of sunlight and chemical composition of fjord water reached in less than 2 days. No significant difference (p > 0.05) in the survival of E. coli from the autochthonous and allochthonous sources. Studies on survival of mesophilic intruders should be carried out for a systematic risk assessment of microbial contamination.},
