Project OAMMS: Observation, Analysis and Modeling of the Mediterranean Sea is a new undertaking of the Operational Oceanography Group of the Centre d'Estudis Avançats de Blanes (CEAB-CSIC). The main objective is to consolidate a system of observation of the Mediterranean Sea through the real-time measurement of a number of meteorological and oceanographic magnitudes with a moored buoy, complemented by periodic visits with a research vessel to the mooring site and assimilation of the observations obtained in order to carry out the systematic forecasting of sea conditions in the NW Mediterranean Sea.
