• The ecosystem monitoring service will focus primarily on reef and mangrove mapping and assessment from a habitat perspective, with additional risk monitoring capabilities at prioritised sites for high-resolution water quality and Virtual Buoy oceanographic monitoring. “Ocean color estimation by Himawari-8/AHI,” in Remote Sensing of the Oceans and Inland Waters: Techniques, Applications, and Challenges, eds R. J. Frouin, S. C. Shenoi, and K. H. Raocpesnm, (New Delhi: SPIE). (1980). Bandwidth can inhibit systematic near-real time processing at a global scale, or analysis of a complete archive. Oceanogr. There are 17 goals and the most relevant in the context of this review are Goal 14: ‘Life Below Water,’ while inland and coastal water colour and water quality is particularly relevant to Goal 6: ‘Clean water and sanitation.’ The SDGs are sometimes considered only with regard to developing countries, but whilst issues in many developing countries are acute, marine pollution, sustainable management of marine ecosystem, ocean acidification and increasing scientific knowledge are relevant to communities worldwide. Hall, D. E. Harrison, and D. Stammercpesnm, (Venice: ESA Publication WPP-306), 21–25. 92, 16–29. Coastal waters are more complex optically on account of the additional influences of re-suspended particulates, or river run-off which could contain terrestrial suspended particulates or CDOM which are independent of the phytoplankton assemblage (International Ocean Colour Coordinating Group [IOCCG], 2000). 132, 46–60. Current capacity building and training activities pertinent to ocean colour are described and finally a summary of future perspectives is provided. Ongoing high-quality in situ radiometric measurements are also needed to validate new sensors in a satellite constellation as well as to test continually the performance of instruments that have been in orbit for many years. (2016) shows interannual variations in chl-a concentration in the Pacific Ocean and close correspondence with the ENSO index. Remote Sens. Skakala, J., Ford, D., Brewin, R. J.

At such heights HAPs provide repeated observations similar to GEO spacecraft, but over a smaller range and at a much lower cost. An ocean-colour CDR is produced by the Copernicus Climate Change Service (C3S) and brokered to CMEMS. In general, OC CCI products meet the GCOS requirements for uncertainty (see Figures 3D,E) though long-term stability is still under investigation. Considerations for identifying key variables have differed from report to report, and included factors such as the important environmental issues to be addressed, key questions to be answered, feasibility, cost, technology available for detection, platforms available for deployment, impact, and spatial and temporal scales of interest. The next decade will see the time series extending to 30 years, which could allow investigation of climate impacts on the ocean ecosystems, for some regions, albeit with caveats on gaps and discontinuities (Henson et al., 2010). Opt. Another intercomparison (Claustre et al., 2004) of four HPLC laboratories found a lower uncertainty (expressed as absolute percentage difference) of 7% for total chl-a across a wide trophic range. The motivation for Copernicus is to ensure continuity and consistency of observations enabling construction of services utilising these EO data. Remote Sens.

This section provides an overview of current and future elements of ocean colour sensors together with relevant in situ data gathering to support ocean colour. Mar. Science 210, 60–63. Interesting phenomena, details and events can be found in the sea and in areas nearby.

(2010) discussed how the operational requirements of satellite observations in general, including ocean colour, differed from research requirements, and how science-driven single missions were transitioning to multi-mission, sustained ocean observations to meet a variety of operational requirements.

It has three goals ‘(1) Demonstrate how Earth observations, geospatial information, and socio-economic and other data contribute in novel and practical ways to support achievement of the SDGs.
