Special Issue Information

Dear Colleagues,

Marine microbes (viruses, bacteria, archaea, fungi, protozoa, and other protists) have evolved by exploiting a multitude of environmental resources, including water currents, light availability, pressure, temperature, and nutrients. They account for a majority of the global biodiversity and mediate the major biogeochemical processes in the World Ocean covering over 70% of the Earth’s surface, including primary production and carbon degradation under oxic and anoxic conditions. Despite the impressive importance of marine microbes and the advances that have been made in studying microbial processes, the mechanisms that underlie the participation of microorganisms in marine food webs and biogeochemical cycles are poorly understood. This Special Issue aims to highlight key research on marine microbial processes occurring on our blue planet in the widest range of scales, from micron to global. Authors are invited to submit papers relating, but not limited, to the following topics: carbon cycle and global climate change; microbial light utilization and primary production; microbial growth, biomass production, and control; degradation of organic matter and microbial ‘loop’; predation and protists; ecology of viruses and viral ‘shunt’; processes in anoxic environments; genomes and meta-omics for microbial processes.

Viral dynamics are the result of the balance between the rates of viral production and decay. Here, we have carried out independent measurements of viral production and decay rates in different depths of the southern East China Sea in summer (August and October 2021). In this study, the prevalence of viral abundance at the surface waters (14.2~27.6 × 105 viruses mL−1) was significantly higher than the bottom of the euphotic zone (2.9~12.6 × 105 viruses mL−1). As for viruses to bacteria ratio (VBR) values, we found a wide variability both at the surface (1.4 to 3.2) and bottom of the euphotic zone (2.1 to 16.2). The results of our study showed that at all stations examined, in the southern East China Sea, the values of gross viral production (GVP) were significantly higher in the sunlit surfaces compared to the bottom of the euphotic zone. In particular, our analysis indicates that no significant viral decay rates (VD) were observed in some regions at the bottom of the euphotic zone. Here, we also provide a budget for viral abundance and net viral production in different regions in the southern East China Sea. The GVP or VD is not applicable in our case to explain VBR is high at bottom of the euphotic zone. The mechanisms underlying VBR uncoupling, viral production, and viral loss in marine systems are still being investigated. Full article
