Members of the ICM Instrumentation Service recovered the Hydrochanges-ICM mooring from the R.V. García del Cid and deployed a new one. This mooring is since 2003 a DOFT contribution to the CIESM Hydrochanges program (Schroeder et al., 2013) and records temperature, conductivity, pressure and current near the bottom in the lower part of the continental slope (1900 m) in front of Barcelona, between the Blanes and Palamós canyons. The recorded data allow monitoring the deep water hydrographic conditions and have been used in several studies that analise the sudden changes of these characteristics linked to specific climatic episodes (Font et al., 2007; Durrieu de Madron et al., 2013).
