Marine Microbiology & Harmful Algal Blooms

The microscopic life forms inhabiting the ocean play an essential role in nutrient cycling, climate regulation, and overall marine productivity. Research in marine microbiology & harmful algal blooms highlights both the beneficial and detrimental aspects of microbial communities in aquatic environments. Marine microbes, including bacteria, archaea, and viruses, drive processes such as carbon sequestration and nitrogen fixation, supporting the food web from its foundation. Yet, under certain conditions, algal species can proliferate excessively, resulting in harmful algal blooms that disrupt ecosystems, deplete oxygen, and release toxins harmful to marine organisms and human health. Advancements in molecular biology, genomics, and remote sensing are deepening our understanding of microbial functions and bloom dynamics. By linking microbial diversity to environmental drivers, scientists are identifying predictive tools and management strategies aimed at reducing the risks of such events. This growing knowledge base strengthens conservation and fisheries management in changing oceans.
