| After a time when observations of the sea have been made for specific purposes, e.g. for specific national purposes or to demonstrate a technological capability, the European Commission has now moved to a new paradigm where data are collected once and used them for as many purposes as possible. This means relying preferably on users rather than on producers to assess existing data sets and data sources and promote recommendations for a better satisfaction of their needs. The EMODNET Atlantic checkpoint (http://www.emodnet-atlantic.eu/) was designed to evaluate the fitness-for-use of current observations and data assembly programs towards 11 marine applications and prioritizing the needs to optimize monitoring systems at the scale of the North Atlantic Ocean. |

| The Global Ocean Data Assimilation Experiment (GODAE [http://www.godae.org]) has spanned a decade of rapid technological development. The ever-increasing volume and diversity of oceanographic data produced by in situ instruments, remote-sensing platforms, and computer simulations have driven the development of a number of innovative technologies that are essential for connecting scientists with the data that they need. This paper gives an overview of the technologies that have been developed and applied in the course of GODAE, which now provide users of oceanographic data with the capability to discover, evaluate, visualize, download, and analyze data from all over the world. The key to this capability is the ability to reduce the inherent complexity of... |

| This report discusses whether, by the year 1995, altimeter mean surfaces such as those generated by Geosat, ERS-1 [35 days] and Topex-Poseidon will be accurate enough for extracting the variable ocean signal. The mean oceanic signal is estimated from altimetry using an inverse method. Because of the large number of altimeter measurements, the original one-step method is transformed to a two-step method, the iterative inverse method. The space-time distribution of the altimeter data is only needed to calculate the formal error on the altimeter mean surface. Using a year of satellite altimeter measurements, the mean rms errors are 10 cm for Geosat, 8 cm for ERS- 1 and 13 cm for Topex-Poseidon. The along-track minima are respectively 8, 7 and 5 cm rms. Errors... |
