T-MedNet network is devoted to spread the acquisition of long term high resolution temperature series in Mediterranean coastal waters (0-40 m) as well as to facilitate data sharing and analysis. The main aims of the T-MedNet network are: - to gather information on high resolution temperature records currently available, - to furnish information on “how to” implement and maintain new high resolution temperature records, and ultimately - to develop a platform for the management and analysis of high resolution temperature records. T-MedNet network users are scientific staff already involved or interested in the acquisition of temperature series (technicians, ecologists, physicians, chemist etc…) and managers of marine coastal areas. T-MedNet is an initiative of the MEDRECOVER research group based at the Institut de Ciències del Mar in Barcelona (Spain).
