Introduction Understanding of ecosystem changes induced by harmful algal blooms (HABs) and their impacts on coastal water quality, bacteria, and zooplankton communities remains limited. Non-toxic HABs, particularly Noctiluca scintillans , are increasingly reported in Indian coastal waters. Methods In the present study, a greenish bloom of N. scintillans was observed along the Gulf of Mannar and the Southeastern Arabian Sea dur...

Luciferidae (Decapoda) are an important component of mesozooplankton in pelagic food webs. This study investigated the spatiotemporal distribution and frequency of Luciferidae swarms along the Tamil Nadu coast, as observed during coastal monitoring cruises conducted between 2019 and 2022. Data were collected on various hydrobiological factors, including surface water temperature, salinity, chlorophyll a , zooplankton biomass,...

The moored buoy network in the Indian Ocean revolutionized the observational programs with systematic time-series measurement of in situ data sets from remote marine locations. The real-time meteorological and oceanographic data sets significantly improved the weather forecast and warning services particularly during extreme events since its inception in 1997. The sustenance of the network requires persistent efforts to overco...
