Humans depend on the coastal ocean for our economy, our lifestyle, and even our food. Fish represents approximately 15.7% of the animal protein consumed worldwide. The economic activity associated with the oceans is crucial. World trade is highly dependent on maritime transport; approximately 50 thousand ships trade internationally, transporting 90% of world trade. The coasts, which concentrate 40% of the world's population, are of utmost importance for recreational activities, generation of green energy, etc.Given these facts and figures, it is not surprising that the oceanic forecast is considered a vital activity. Since the first attempts at ocean forecasting during the world war II, the technique has evolved into what it is today, a complex body of codes, data and technologies capable of dealing with the chaotic and non-linear nature of ocean processes, thanks to the constant increase in computing capacity. Despite advances in global ocean modeling over the past two decades, coastal-scale forecasting still poses a particular challenge. Today, the scientific modeling community seeks to improve the reliability of these forecasts by advancing primarily in three cutting-edge areas: data assimilation, coupled forecasting, and ensemble modeling. During the talk, the state of oceanic forecasting models for coastal regions and the efforts being made in Argentina in relation to the subject will be discussed.
