BIOLOGY IN THE SEDIMENT

*CENTRE - NAME: Hellenic National Oceanographic Data Centre (HNODC), National Centre for Marine Research (NCMR)

*TIME - PERIOD: March 1997 - September 1997

*GEOGRAPHIC - COVERAGE: North and South Aeagen Sea.

*PROJECT: MASTIII/MTPII - MATER.

*PARAMETERS: Depth below sea bottom, bacterial density through 3 sediment layers and bacterial density in superficial sediment (0 to 6 cm depth), potential proteolytic activity (Vmax) and potential ¹⁴C-glutamate respiration rate (Vmax) through 3 sediment layers, potential proteolytic activity (Vmax) and potential ¹⁴C-glutamate respiration rate in superficial sediment (0 to 6 cm depth).

*INSTRUMENTS: 0.1 m2 USNEL Boxcorer and a Bowers/Connely multicorer were used to collect sediment samples.

*SUMMARY: Sediment cores were sliced in 3 depth layers (0-2, 2-4, 4-6 cm), processed and analysed immediately on board to determine proteolytic and respiration rates. Samples were also preserved for later determination of bacterial abundance .

Volume/Number of Profiles: 14 profiles
