Ocean

The primary objective of the Ocean Scenario (undertaken by the partners BODC (UK), CLS (FR), HCMR (GR), IFREMER (FR) and MARIS (NL) is to test the Humboldt Framework for its ability to solve data harmonisation issues in applications for assessing and managing marine and ocean oil/contaminants spill crises. The Ocean Demonstrator can be split in two parts:

  • Data integration solving harmonisation issues using the framework components
  • Visualisation of harmonised datasets using defined standards and components and thus proving the solution works.

The basis for the demonstrator can already be found in existing developments in the Ocean domain. In three regions the Humboldt partners have been (and still are) developing models, as well as viewing and decision support software to determine the best solution in case of an oil spill crisis. These applications are developed to assist decision makers in the regions to decide which countermeasures are needed.

The modelling components, based on physical oceanographic data, (waves, wind, currents etc), are very ocean domain specific and will not be affected by Humboldt developments. However the input of datasets and output of the modelling software definitely will be. Harmonisation and standardisation of input and output will make the data useful in a wider area, and will improve the set up time for a new case when a crisis occurs. Harmonised datasets, discoverable via a catalogue and accessible via services in a common protocol can easier (and much quicker and cheaper) be included in the decision support software.

Another important area is the cross-domain approach that is being taken. Two different information communities are involved in this deployment area, with specific technology and data: that of 'sea/ocean' and 'land'. Until now the viewing and decision support software lacked input from the land domain because appropriate datasets were hard to find and to use. This is caused by a low degree of cross-border standardisation and harmonisation. It means for example that image data (raster) of the ocean part will be combined with topographic and ecological data (vector) of the beaches and shores.

The Humboldt framework software and standards help to bridge the different worlds, each tradi­tionally with its own software, (meta)data, procedures, and standards. The Humboldt Framework supplies software components and processes to solve the harmonisation and standardisations in the Ocean domain, so to transform datasets from source to target model. Within the Ocean domain itself there are already many harmonisation solutions in place, but they are limited to the marine and ocean community. The Humboldt software components are being tested if they have the capability to make the step from one domain to the other and if they take into account the specific Ocean demands.
