Dispersion of the oil spill in the marine environmen<\/strong>t: Oil spill models constitute an essential element in contingency planning and in preparing effective response strategies to combat hazardous oil spills at sea. Such models rely on the ability to predict meteo-marine conditions of the sea through the use of cross-sectorial data, including atmospheric, wave and hydrodynamical numerical models. Integrating and combining the information on the location, rate, nature and characteristics of an oil spill, the derived forecasted fields is used to provide, in advance, some knowledge on the fate and track that the oil slick will follow in time. Such a chain of numerical model activities can be automated and run in operational mode to provide a round-the-clock service, relying on sufficient computing power, which is nowadays becoming more affordable.<\/p>\n

The POSEIDON Oil Spill Model has been implemented at the Hellenic Centre for Marine Research (HCMR) and it is used operationally for the Aegean and Ionian Seas. It is a fully 3D oil spill model capable of simulating the movement, spreading and aging of the oil particles in the 3-D space. In the current operational implementation of POSEIDON Oil Spill Model (OSM) in the Greek seas, the model uses atmospheric data from the POSEIDON ETA weather forecasting system, wave data from the POSEIDON WAM Cycle 4 for Aegean and oceanographic data from the POSEIDON Aegean model. The POSEIDON OSM is a standard module of the POSEIDON operational Oceanography System that has been implemented and has operated in Greek seas since 2000. Tt was further developed during ESA\u2019s projects ROSES (2003-2004) and MARCOAST (2005-2008) and EU project ECOOP (2008-2011), while it is one of four numerical components of the multi-model MEDESS4MS project (2012-2015).<\/p>\n

Challenges:<\/strong> The presented-above numerical modelling activity is widely used to support operational activities in the marine environment and thus the reliability of its output is of crucial importance. The integration of existing systems and data, in one unified big data infrastructure accompanied by proper services, and additional datasets of interest, could provide additional information that could increase the forecasting skill and improve the effectiveness of operational activities; and thus, have significant impact on marine, and environmental in general, protection.<\/p>\n

BigDataOcean Solution<\/strong>
\nAs already explained above, the oil spill dispersion models rely on the results of other numerical models that provide the necessary atmospheric, hydrodynamic and sea state input. Thus, what would add significant value is the integration and exploitation of additional information coming from different sectors that would significantly improve the input into the series of interconnected systems of numerical models.
