Visible spectral radiometric measurements from space, commonly referred to as ocean-col�our measurements, provide a rich stream of information on ocean biota as well as on bio�logical and ecosystem processes. The strength of the ocean-colour technology for observ�ing marine life lies in its global reach, combined with its ability to sample the feld at a variety of spatial and temporal scales that match the scales of the processes themselves. Another advantage lies in the growing length of the time series of ocean-colour-derived products, enabiling investigations into any long-term changes, if present. This paper pre�sents an overview of the principles and applications of ocean-colour data. The concen�tration of chlorophyll-a, the major pigment present in phytoplankton–single-celled, free�foating plants that are present in the sunlit layers of the ocean–was the frst, and remains the most common, biological variable derived from ocean-colour data. Over the years, the list of ocean-colour products have grown to encompass many measures of the marine eco�system and its functions, including primary production, phenology and ecosystem struc�ture. Applications that exploit the data are many and varied, and include ecosystem-based fsheries management, biogeochemical cycles in the ocean, ecosystem health and climate change. An integrated approach, incorporating other modes of ocean observations and models with satellite observations, is needed to investigate the mysteries of the marine ecosystem
