Eighty-six countries are involved in ocean observations with about 10 000 in situ ocean observing platforms and 170 satellites continuously monitoring the global ocean and atmosphere. The analyses, forecasts and products based on ocean observations are the bedrock of decisions across a swath of socio-economic sectors, especially in marine transportation, coastal communities, climate, agriculture and ocean health. Society's need for ocean information is increasing. In response, the Global Ocean Observing...
