DATA BASE DESCRIPTION (EDMED Part B)

*DATASET-NAME: Scientific cruise URANIA 15/97 (SINAPSI Project), monitoring a regional transient climatic event in the Ionian Sea waters: CHIRP profiles

*TIME-PERIOD: 1997, November, 19 to 1997, December, 10

*GEOGRAPHIC-COVERAGE: 70 profiles covering the Ionian Sea (data set limits: South: 34N; North: 38N; West: 15E; East: 23E)

*PROJECT: SINAPSI (Seasonal, Interannual and decAdal variability of the atmosPhere, oceanS and related marIne ecosystems) Project in the Mediterranean Sea. Coordinating Body: CNR, Istituto Geologia Marina (IGM), Bologna, Italy

*PARAMETERS: high resolution sub bottom profiles, CHIRP profiles, Malta escarpment, Calabria escarpment, Ionian abyssal plain, Victor Hensen sea-hill, Mediterranean Ridge, Matapan Trench, anoxic basins

*INSTRUMENTS: Chirp II, sub bottom profiling

*SUMMARY: CHIRP data set is a group of high resolution sub bottom profiles, acquired to allow for characterizing the sites where to perform corings and HF measurements. In addition, some profiles were acquired for investigating the anoxic brine lakes in the NE flank of the Mediterranean Ridge and the Victor Hensen sea-hill in the Ionian Abyssal Plain. CHIRP data, recorded in digital form on magneto-optical device, can be processed using standard reflection seismics packages. Claimed performance parameters are: max theoretical vertical resolution: 10 cm; max penetration in sediments: 100 m.
