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: GRAVITY CORER stations

*TIME-PERIOD: 1997, November, 22 to 1997, December, 9

*GEOGRAPHIC-COVERAGE: 3 stations, located: at a morphological high on the continental slope SW of Crete, in the "mud pit" of the "Urania" brine lake (NE flank of the Mediterranean Ridge) and on top of the Victor Hensen Sea Hill (Ionian Bathyal Plain), respectively (data set limits: South: 35N; North: 36N; West: 18E; 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: sapropels, nannofossils, biostratigraphy, foraminifera, geochemics, Ionian abyssal plain, Victor Hensen sea-hill, Mediterranean Ridge, Matapan Trench, brines, anoxic basins

*INSTRUMENTS: 1.2 tonn GRAVITY CORER

*SUMMARY: The sea bottom sampling in the SINAPSY campaign were finalized to characterization of sapropel, with special care to sapropel S-1. In formulating possible formation models for the sapropels in the Eastern Mediterranean, the following parameters are essential: geographical extension and continuity of the level in a basin; minimum and maximum depth of foundings in the sediment; apparent variations in sapropel thickness, related to water depth and geographical location. The sapropel evidences were searched moving from the western limit of the Eagean Sea into the Ionian Sea, toward SW (Syrte Basin and Sicily Channel) and W (Sicily Strait). In relatively shallow waters (1000 m) we adopted a gravity corer instead of the box corer: it allows also to obtain a more deep sediment recovery. Station #2 was performed in the "mud pit" of the "Urania" brine lake, to recover a sample of the anoxic sediments
