The Sicily Channel is a key area for Mediterranean oceanography as it intercepts all water masses exchanged between the eastern and western Med. basins. Its hydrological properties are monitored by two moorings of the CIESM HydroChanges network. These moorings provide, two of the longest-running Mediterranean time series of thermohaline properties. A paper just published by our programme coordinator (Dr Katrin Schroeder) analyses these data, highlighting a steady increasing trend in T / S, much higher than that observed in the world ocean. Because of its small volume to surface area ratio, the Mediterranean Sea is one of the first to respond to global warming and to changes in freshwater inputs.
