Objectives:

This was the third cruise of the project MATER (MAss Transfer and Ecosystem Response) that concentrated on the study of the benthic environment at the selected stations of the South and North Aegean Sea.

The main tasks involved:

- collecting sediment samples with an 0.25 m2 USNEL Boxcorer and a Bowers/Connely multicorer from 3 stations in the South (MSB1, 2, 3) and 7 stations in the North Aegean Sea (MNB1, 2, 3, 4, 6, 8, 9) for determining the:

  1. benthic macrofauna, meiofauna and foraminifera community structure
  2. microbial density and potential microbial activity
  3. nutrient content concentration in the near bottom water
  4. TOC, TON, Chloroplastic pigments, ATP and LOC concentrations
  5. temperature and Eh of the sediment

- deploying the NIOZ's benthic lander, BOLAS, to obtain in situ SCOC (sediment community oxygen consumption) measurements, to video record and identify potential scavengers attracted to the attached baited traps.
