The distribution and heterogeneity characteristics of microbial communities in cold seep
water columns are significant factors governing the efficiency of methane filtering and …

Nitrogen-fixing or diazotrophic microbes fix atmospheric nitrogen (N2) to ammonia (NH3+)
using nitrogenase enzyme and play a crucial role in regulating marine primary productivity …

ABSTRACT The Mariana Trench, a stable marine ecosystem minimally impacted by human
activities, has the greatest vertical depth in the ocean. Depth gradients profoundly influence …

Archaea constitute a substantial fraction of marine microbial biomass and play critical roles
in the biogeochemistry of oceans. However, studies on their distribution and ecology in the …

The thawing of snow and sea ice produces distinctive melt ponds on the surface of the Arctic
sea ice, which covers a significant portion of the surface sea ice during summer. Melt-pond …

Microbes are core to drive biogeochemical cycles and differ between sun-drenched surface
and relatively dark deep oceans. However, their distinct contributions to the organization …

Indian work in Antarctica has covered mainly atmosphere, biology and geoscience domains
of sciences in central Dronning Maud land and Princess Elizabeth land (PEL) of eastern …

Kuroshio Extension (KE) is the most active region of oceanic change in the North Pacific
Ocean, which provides an essential place for the survival of marine microorganisms …

The oxygen minimum zone (OMZ) is an important representative of marine hypoxia in the
open ocean, and it is developing rapidly under the context of global warming. However, the …

Abstract The bacterioplankton of Lake Khubsugul (Hövsgöl) has significant differences from
that of large ancient and oligotrophic water bodies. The greatest similarity was noted …
