“…The species detected in this study add more information to the findings of previous reports on zooplankton (Asami et al, 2007; Hikichi et al, 2018; Hirai et al, 2015, 2017; Pinchuk & Paul, 2000), harmful algal species (Sildever et al, 2019; Stonik & Orlova, 2013), winter microalgal communities (Yan et al, 2022), and protists in general (Matsumoto et al, 2021). Using zooplankton as an example, similar to previous studies from the same sampling location, most of the OTUs were associated with copepods (especially calanoids), Polychaeta, and Hydrozoa (Hirai et al, 2015, 2017).…”

“…This has resulted in reduced sea ice coverage (Ohshima et al, 2009), which has implications for local biological productivity (Mustapha & Saitoh, 2008). Through the reduction of water, nutrients, and organic carbon reaching the North Pacific, the local reduction in sea ice may have a broader impact on the regional biological production, fisheries resources, and carbon sequestration capacity (Ohshima et al, 2009; Yan et al, 2022).…”

Detection of marine organisms based on environmental DNA (eDNA) has expanded the knowledge of species richness, distribution, and appearance patterns. We used eDNA data from a single location sampled weekly over 8 years to detect as many species as possible, and investigate their appearance patterns and associations with biotic and abiotic factors. We detected >2500 operational taxonomic units (OTUs) associated with unique species from nine supergroups. The dominating currents that differ significantly in temperature, salinity, and nutrient concentrations structured the richness of the OTUs. We further detected sporadic and seasonal or continuous presence among the OTUs connected with a single species. This study shows that the long‐term eDNA‐based monitoring approach provides comprehensive knowledge of the species present as well as their associations with biotic and abiotic factors.
