*DATASET-NAME: CTD station data collected in the Southern Adriatic Sea during the Italian PRISMA programme, Phase 1 (1995-1996)

*TIME-PERIOD:  From May 1995 to February 1996 (four seasonal cruise).

*GEOGRAPHIC-COVERAGE: Parallel transects over the steep continental slope of the Southern Adriatic Basin (the Gargano transects), and at the southern opening to the Ionian Sea (the Otranto transects), data set limits: South: 39°N; North: 42°N; West: 15°E; East: 20°E.

*PROJECT: PRISMA (Programma di RIcerca e Sperimentazione del Mare Adriatico)

*PARAMETERS: Pressure, temperature, salinity, dissolved oxygen, light transmission, fluorescence, as well as Secchi depth and basic air-sea interface parameters.

*INSTRUMENTS: CTD SeaBird 911 plus, coupled with a 24-bottles Rosette water sampling. The CTD was equipped with SeaTech Transmissometer and SeaTech Fluorometer. Additional SIS reversing thermometer readings, and Guildline bench salinometer for samples analysis were used for CTD data quality control and intercalibration. The transmissometer and fluorometer data were obtained according to manufacture calibration. No intercomparison with other measurements were performed.

*SUMMARY: Four multidisciplinary seasonal hydrological surveys with CTD casts and water sampling were conducted every three months (May, August, November 1995, and February 1996) in the framework of PRISMA sub-project "Longitudinal fluxes" in the Northern Adriatic, in the Central Adriatic and in the Southern Adriatic respectively. The main objective was the study of the seasonal time-scale variability of the water and the biogeochemical fluxes, through four significant transversal sections of the Adriatic Sea. Water sampling for the determination of nutrients and dissolved/particulate elements were collected, contemporary with marine currents measurements both by mooring arrays of currentmeters and ship-mounted ADCP current profiles.

The original CTD data were processed, controlled and analysed by the originators who hold the principal quality control responsibility. The high resolution vertical profiles of each station were averaged over 1 dbar pressure interval. The salinity has been computed according to the 1978 Practical Salinity Scale. The averaged data are stored per cruise and ship (institution).

The entire data set comprises 956 vertical profiles and includes data supplied by three institutions:
- Istituto Nazionale di Oceanografia e di Geofisica Sperimentale – OGS, Trieste, Italy (Gargano and Otranto transects);
- CNR, Istituto di Scienze Marine (Sezione di Ancona), Italy (Giulianova transects);
- CNR, Istituto di Scienze Marine (Sezione di Venezia), Italy (Rimini transects).

The Southern Adriatic data set comprises 548 vertical prifiles related to four seasonal cruises by OGS, Trieste.
