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:

  1. to gather information on high resolution temperature records currently available,
  2. to furnish information on “how to” implement and maintain new high resolution temperature records
  3. 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).

Why to measure the temperature in Mediterranean coastal waters?

In the NW Mediterranean changes in species distribution and mass mortality events reported during the last several decades have been related to the warming trend observed in this area. In particular, large scale mass mortality events (MME) of long-lived benthic species that have occurred in 1999 and 2003 have been related to anomalous temperature conditions. Nevertheless and despite the notable exceptions of local temperature series, there is an enormous gap of knowledge on temperature regime in coastal waters (0-40 m) due to the lack of data sets covering the appropriate (high resolution) temporal and spatial scales. At present, large scale sea surface temperatures obtained through satellite images and the few limited time-resolved T series prevent the characterization of the spatial and inter-annual variability in the coastal water column.

Gaining robust data sets on thermal regimes is critical to assess conditions to which species have adapted, detect extreme events and critically evaluate biological impacts. Besides given actual warming trends and projections in NWM, the repetition of new MMEs in the next decades is extremely likely. In such context, the acquisition of dedicated high resolution T series proves to be crucial for increasing our detection, understanding and forecasting abilities. These abilities will be key to implement sound conservation and management plans for the conservation of the rich Mediterranean biodiviersity.
