概要	Hydrothermal plume mapping is an integrated method for detecting, characterizing, and tracking buoyant plumes of hot, mineral-rich water discharged from submarine hydrothermal vents on the seafloor. Developed by Ed Baker and colleagues in the 1980s, hydrothermal plume mapping combines temperature, conductivity, optical, and chemical sensors to identify vent signatures and map their dispersal in the water column. The method enables discovery of new vents and assessment of chemical cycling in deep-sea ecosystems.	Ocean color remote sensing is the primary global method for retrieving seawater chlorophyll-a concentrations and phytoplankton productivity from satellite sensors. Based on bio-optical principles established in the 1970s, ocean color algorithms convert satellite spectral reflectance measurements into estimates of chlorophyll-a pigment concentration. This method enables global-scale, real-time monitoring of oceanic primary productivity and plankton dynamics.
