The paper quantifies benthic biodiversity in the Weddell Sea by integrating geomorphology, oceanography, and predictive modeling, identifying hotspots linked to specific environmental conditions.

This study examines microbial and carbohydrate connectivity across ocean, atmosphere, and cryosphere in Kongsfjorden during autumn and spring, identifying distinct ecosystem states and microbial transfer patterns.

The paper sequenced complete genomes of 34 Arctic marine bacteria to identify gene gain, loss, and rearrangement patterns linked to adaptation to Arctic conditions.

The paper studies Arctic Ocean virus communities over four years, revealing seasonality, bipolar distribution, and interactions with prokaryotes.

The paper introduces GRUMP, a database of global ocean microbial communities using universal primers, enabling direct comparison of taxonomic ratios across samples and domains.

The paper examines seasonal dynamics of an Arctic pelagic microbiome, revealing modular patterns in taxonomic and functional composition across four years.

This paper develops a time series analysis framework to identify seasonal keystone species and assess Arctic pelagic ecosystem stability using microbial community data.
