SARTI-MAR - Sistemes d'Adquisició Remota de dades i Tractament de la Informació en el Medi Marí
El grup de recerca SARTI-MAR té com objectiu fonamental el desenvolupament de instrumentació científica de paràmetres ambientals, amb especial èmfasi en el medi marí. Gràcies a les infraestructures desenvolupades al voltant del observatori submarí Obsea (www.obsea.es), existeix una forta interacció entre col·lectius d’enginyers i científics, nacionals e internacionals. Interacció orientada a l'estudi dels processos oceànics relacionats amb els ecosistemes marins, el canvi climàtic i els riscos mediambientals. Les tecnologies de mesura dels observatoris submarins permeten obtenir dades amb prou resolució temporal per registrar esdeveniments "singulars" però claus en la dinàmica dels processos i obtenir la informació in situ per analitzar fenòmens específics. La capacitat d'abastar un ventall tant ampli d'escales espai-temporals d'observació proporciona noves oportunitats de recerca i desenvolupament, tant en projectes de recerca bàsica com en innovació tecnològica.
