| Description: | 8 pages, 4 figures. [EN] Time series measurements at a mooring site on the deep slope of the NW Mediterranean from October 2003 to July 2005 revealed the sequence of effects of the anomalously dry, markedly cold, and very windy winter of 2005 in deep water thermohaline properties. At the end of January, a dense water mass that was warmer and saltier than usual reached the deep slope mooring site. Almost simultaneously, the start of deep dense shelf water cascading episodes was observed in the Gulf of Lions’ submarine canyons. 30 days later, colder, fresher and even denser waters reached the mooring, with a 5-day delay from an intensification of the Gulf of Lions’ cascading. The signature of these waters was detected for 35 days, and by late spring 2005 a new stable water mass situation was reached, with higher thermohaline values than those that characterised the deep layer from October 2003 to January 2005. [ES] Una serie temporal de datos registrados en un anclaje en la parte profunda del talud continental del Mediterráneo noroccidental desde octubre de 2003 a julio de 2005 muestra la secuencia de los efectos del invierno de 2005, anómalamente seco, destacadamente frío y muy ventoso. A finales de enero una masa de agua densa, más caliente y salada de lo habitual, llegó al anclaje del talud profundo. Casi simultáneamente se observó en los cañones del Golfo de León el inicio de episodios de hundimiento profundo de agua densa de plataforma en forma de cascada. Al cabo de 30 días, 5 días después de intensificarse el hundimiento en cascada en el Golfo de León , aguas más frías, menos saladas, y todavía más densas, alcanzaron el anclaje y permanecieron allí durante 35 días. A finales de la primavera de 2005 se alcanzó un nuevo estado estacionario con valores de temperatura y salinidad más elevados que los característicos de la capa profunda desde octubre de 2003 hasta enero de 2005. This is a contribution to the CIESM HydroChanges programme and to project MIDAS-4 funded by the Spanish National Programme on Space (ESP2005-06823-C05). The moorings in the submarine canyons were funded by the EuroStrataform project (EU Fifth Framework Programme, EVK3-CT-2002-00079) and the US Office of Naval Research (ONR Grant N00014-04-1-0379). The deployment and recovery operations for the HC-ICM mooring were done during campaigns on board the B/O García del Cid (MFSTEP project, EU Fifth Framework Programme, EUK3-2001-00174) and the B/O Cornide de Saavedra (TUNIBAL project, Instituto Español de Oceanografía).
