The Northern Indian Ocean (NIO) is one of the most characteristic regions world oceans with diverse oceanographic features. Understanding microbial community structure in these unique habitats has rapidly increased last decade, especially advent molecular tools and application NGS technologies. Studies on marine ecology NIO regions, from pre-genomics era relied culture techniques, microscopic observations, qualitative plate assays biochemical tests. Molecular techniques 16S rRNA gene sequencing introduced after late 1990s significantly enhanced understanding bacterial diversity. These revealed presence phyla provided insights into their functional characteristics. Recent, NGS-based metagenomic studies further expanded structures, oxygen minimum zones deep-sea sediments. have identified taxa in-depth, revealing existence numerous Candidatus known only by genomic makeup. Despite advancements, a large part diversity remains unexplored, many unanswered questions related to carbon pump. Further transcriptome based can greatly improve processes NIO, which dynamic, habitat.

Introduction Power plants discharge thermal and cold effluents that significantly alter marine environments, impacting various organisms, including benthic communities. While has received considerable research attention, the impacts of remain underexplored. This systematic review synthesizes existing on effects power plant discharges ecosystems. Methods A literature search was conducted using Scopus, PubMed, Web Science, following PRISMA guidelines, covering studies from 1974 to 2024. total 58 articles were included in this review. CiteSpace used visualize trends, statistical analysis assess relationships between environmental parameters changes abundance. Results significant negative correlation observed temperature differentials, ambient temperature, Thermal generally led reduced diversity abundance, with occasional increases under low temperatures. Cold less documented, evidence primarily focused phytoplankton fish. Additionally, dissolved oxygen, pH, bottom sediment composition altered by discharge. Detection mitigation measures are crucial managing these impacts. Mitigation include distributed for effluents, advanced heat recovery systems, careful site selection minimize sensitive Long-term management adaptive strategies essential reduce adverse maintain ecological balance. Discussion adversely impact organisms decreasing biodiversity changing community structure, largely due elevated temperatures oxygen levels. present unique challenges require further fully understand their measures, such as systems discharges, operations.
