The ocean around Iceland, where warm Atlantic and cold Arctic currents meet, is a unique marine environment. While primary production in Icelandic waters has been monitored since the 1950s with microscopy and satellite imaging, molecular insights into microbial taxonomic and metabolic diversity remain limited. This thesis investigates the microbial communities in Icelandic marine waters using metagenomics. The main objectives were to find out what species can be detected in Icelandic marine waters? in what proportions? what is their potential function in the marine ecosystem? and how do environmental factors shape their distribution?<\/p>\n<p>The findings of this thesis offer insights into the relationships between microbial communities and their environments, establishing a foundation for future research. The publicly available datasets from this study serve as a baseline, supporting ecosystem modelling and sustainable management of Icelandic marine waters in a changing climate.<\/p>\n<p><strong>Um doktorsefni\u00f0 <\/strong><\/p>\n<p>Clara Anne Th\u00e9rese J\u00e9gousse f\u00e6ddist \u00ed Frakklandi \u00e1ri\u00f0 1991.
