A great wealth of ocean data exists, for a wide range of disciplines, derived from in-situ and remote sensing observing platforms, in real-time, near-real-time and delayed mode. These data are acquired as part of routine monitoring activities and as part of scientific surveys by a few thousand institutes and agencies all around the world. Both the means to acquire these data and the way in which they are used have changed greatly in the past ten years.
Over the last decade, information technology has progressed a great deal. It presently allows the exchange of gigabytes of data and more via the Internet in developed countries. In the late nineties, it was considered high technology to provide data on CDROM rather than on magnetic tapes and only small datasets were distributed via the Internet. Nowadays CDROMs are considered as a backup delivery system especially for countries with poor Internet connections. The explosion in use of the Internet has provided new communications capabilities, new tools, and a new way of using computers.
The nature of requirements from government agencies have changed: they want to know or estimate what the future of the earth will look like and what will be the impact on their territories due to climate change issues, ocean health monitoring and fisheries assessment, but they can't pay the full bill for the data acquisition. Therefore, they are pushing, and nowadays more often imposing, a change in data policy and a move towards increased data sharing, in which data acquired with public funds should be freely available to the community.
Moreover, the nature of science itself has changed. Investigators and research funding agencies are looking for context, impacts, and synthesis, rather than just focusing on individual, well-defined processes. Most scientists need the data collected by others as well as their own. They cannot do their work using only data they have collected themselves.
Finally, the growth of operational oceanographic services, based on downscaling of global model results, is really important. These are in demand by users especially for real/near real-time data just as operational meteorology has been doing for a long time.
