    Description / Table of Contents: Zusammenfassung Lange Beobachtungsreihen von Druck und Temperatur von Stationen an der italienischen NW-Küste werden verwendet, um die wichtigsten zeitlich-räumlichen Strukturen herauszuarbeiten, welche die Dynamik des ligurischen und Tyrrhenischen Meeres im nordöstlichen Teil des westlichen Mittelmeeres beinflussen. Beide Parameter zeigen, daß einige periodische Schwankungen (20, 6–8, 4 und 2–3 Tage) die Atmosphäre über beiden Meeren beeinflussen. Eine räumliche Strukturanalyse weist deutlich auf ein generelles System, für das Ligurisch-Tyrrhenische Becken sowie auf ein eher lokales System hin, welches zur zyklonalen Zirkulation im Ligurischen Meer paßt. Die Zuverlässigkeit der aufgezeigten Strukturen und deren räumliche Kohärenz weisen darauf hin, daß für Perioden ab wenigen Tagen die meteorologischen Stationen an der Küste ein realistisches Bild der wesentlichen Ereignisse der beiden Meeresbecken zeigen.
    Notes: Summary Long records of pressure and wind data along the NW Italian coast are used to investigate the most relevant space and time scales influencing the marine dynamics of the Ligurian and Tyrrhenian Seas, in the N. Eastern part of the W. Mediterranean Sea. Both parameters indicate that some basic oscillations (20, 6–8, 4 and 2–3 days) affect the atmosphere of the two basins. From the spatial structure analysis a general system for the whole Ligurian-Tyrrhenian basin and a more local system fitting the cyclonic circulation of the Ligurian Sea are emphasized. The reliability of the evidenced structures and their spatial coherence constitute an indication that, for time scales longer than a few days, the meteorological coastal data provide a realistic representation of the principal events of the basins.

    Description: The long-term monitoring of basic hydrological parameters (temperature and salinity), collected as time series with adequate temporal resolution (i.e. with a sampling interval allowing the resolution of all important timescales) in key places of the Mediterranean Sea (straits and channels, zones of dense water formation, deep parts of the basins), constitute a priority in the context of global changes. This led CIESM (The Mediterranean Science Commission) to support, since 2002, the HYDROCHANGES programme (http//www.ciesm.org/marine/programs/hydrochanges.htm), a network of autonomous conductivity, temperature, and depth (CTD) sensors, deployed on mainly short and easily manageable subsurface moorings, within the core of a certain water mass. The HYDROCHANGES strategy is twofold and develops on different scales. To get information about long-term changes of hydrological characteristics, long time series are needed. But before these series are long enough they allow the detection of links between them at shorter timescales that may provide extremely valuable information about the functioning of the Mediterranean Sea. The aim of this paper is to present the history of the programme and the current set-up of the network (monitored sites, involved groups) as well as to provide for the first time an overview of all the time series collected under the HYDROCHANGES umbrella, discussing the results obtained thanks to the programme.
