Two robotic buoys that will gather information about the ocean’s carbon cycle
have been launched in the Pacific about 1500 kilometres west of Vancouver. The
buoys, dubbed Solos, were developed at the Scripps Institution of Oceanography
in California. They descend to a depth of 1 kilometre to measure carbon biomass,
temperature, salinity and ocean currents. At dawn and dusk, the buoys rise to
the surface to transmit their data via satellite.
