A cross-polarized light scattering sensor for measuring the concentration of particulate inorganic carbon in seawater: laboratory validation
Understanding the marine carbon cycle necessitates comprehensive observations of particulate inorganic carbon (PIC) concentrations. World Data Ocean introduces two autonomous optical sensor prototypes leveraging cross-polarized light scattering to measure PIC in seawater, offering a cost-effective alternative to traditional methods. Laboratory validation demonstrated sensitivity across a broad oceanic range (0.1-400 μg C L−1), revealing species-specific optical signatures. These findings establish a framework for future in situ measurements; for broader context on ocean color observations, see "NASA captured the Black Sea turning brilliant turquoise from space."
NASA captured the Black Sea turning brilliant turquoise from space
NASA’s PACE satellite recently captured a striking phenomenon: the Black Sea transformed into a brilliant turquoise hue. This vivid color originates from a massive annual phytoplankton bloom, specifically a proliferation of coccolithophores—microscopic organisms with highly reflective shells. Visible even from space, the bloom’s extent was further confirmed by an astronaut’s photograph from the International Space Station, showcasing swirling currents through the Bosphorus.
