*DATASET-NAME : Mass fluxes of particulate organic carbon and nitrogen, in the Adriatic, Otranto Strait Sea and Ionian Sea.
*TIME-PERIOD : 1997 to present
*GEOGRAPHIC COVERAGE : Southern Adriatic Sea, Otranto Strait and Northern Ionian Sea
*PROJECT : MASTIII/MTPII/MATER, MAss Transfer and Ecosystem Response
*PARAMETERS : Total mass flux, particulate organic carbon and particulate nitrogen measurements, on samples collected by sediment traps located below the euphotic layer and 150 m above the bottom.
*INSTRUMENTS : Sediment Traps Technicap mod. PPS 4/3, PPS3/3 and PPS5/2. Organic Carbon and Nitrogen were analysed by a Perkin-Elmer CHN 2400 elemental analyser. Grain size was determined by a Coulter Counter mod TA II.
*SUMMARY : Data were collected within the framework of multidisciplinary studies aimed at investigating the physical, chemical and biological characteristics of the Adriatic/Ionian basin.
To determine the vertical fluxes, sediment traps coupled with current meters
were used. The sampling period was 15 days. The collecting bottles were filled
with a preservative formaline solution.
Aliquots of samples were filtered on fiber glass filters to determine the total mass(dry weight), total and organic carbon and total nitrogen. Particle size analyses were carried out by means of a Model TA II Coulter Counter adopting the two-tubes technique (50 and 280 Ám) to cover a wider range. The observed size ranged from 1 to 100 Ám.
