Sediment reworking rates in deep sediments of the Mediterranean Sea
Different pelagic areas of the Mediterranean Sea have been investigated in order to quantify physical and biological mixing processes in deep sea sediments. Herein, results of eleven sediment cores sampled at different deep areas (> 2000 m) of the Western and Eastern Mediterranean Sea are present...

| description | Different pelagic areas of the Mediterranean Sea have been investigated in order to quantify physical and biological mixing processes in deep sea sediments. Herein, results of eleven sediment cores sampled at different deep areas (>
2000
m) of the Western and Eastern Mediterranean Sea are presented.
210Pb
xs and
137Cs vertical profiles, together with
14C dating, are used to identify the main processes characterising the different areas and, finally, controlling mixing depths (SML) and bioturbation coefficients (
D
b). Radionuclide vertical profiles and inventories indicate that bioturbation processes are the dominant processes responsible for sediment reworking in deep sea environments.
Results show significant differences in sediment mixing depths and bioturbation coefficients among areas of the Mediterranean Sea characterised by different trophic regimes. In particular, in the Oran Rise area, where the Almeria-Oran Front induces frequent phytoplankton blooms, we calculate the highest values of sediment mixing layers (13
cm) and bioturbation coefficients (0.187
cm
2
yr
−1), and the highest values of
210Pb
xs and
137Cs inventories. Intermediate values of SML and
D
b (~
6
cm and ~
0.040
cm
2
yr
−1, respectively) characterise the mesothrophic Algero-Balearic basin, while in the Southern Tyrrhenian Sea mixing parameters (SML of 3
cm and
D
b of 0.011
cm
2
yr
−1) are similar to those calculated for the oligotrophic Eastern Mediterranean (SML of 2
cm and
D
b of ~
0.005
cm
2
yr
−1).
► Physical and biological mixing processes in the Mediterranean Sea are investigated. ► Results of 11 sediment cores in deep areas of the Mediterranean Sea are shown. ►
210Pb
xs and
137Cs vertical profiles are analysed. ► New data on
210Pb and
137Cs inventories of Mediterranean deep sediments are given. |
