This dataset includes near real-time global ocean temperature and salinity measurements taken by shipboard observers or automated instruments and received daily by the Marine Environmental Data Section (MEDS) of the Ocean Sciences Branch of Fisheries and Oceans Canada from the Global Telecommunication System (GTS) of the WMO World Weather Watch. MEDS applies the documented GTSPP quality assessment and duplicates removal procedures and forwards the quality-checked data three times each week to the NOAA National Centers for Environmental Information (NCEI).

Ocean color standard products include normalized water-leaving radiances, chlorophyll-a concentration, diffusive attenuation coefficient at 490 nm and diffusive attenuation coefficient of the photosynthetically available radiation (PAR).
