  • Preliminary results of the modern distribution of the benthic foraminifera in the Channel of Sicily (off Gela, 200-1000m w.d.) and in Malta escarpment (200-3000m w.d.) are presented. These areas are investigated within EC project HERMES to verify the possible impact on the biodiversity of two recent slope failures (the NW slides characterised by pressure ridges and the SE slides by blocks). The stratigraphic record of cores (based on foraminifera micropaleontology, lithology, isotope stratigraphy, radiocarbon datings and magnetic properties) suggests that the age of the most recent failures is younger than 3.5 kyrs B.P. Results are: 1) strong differences present between samples collected in the slide scars, 2) the distal areas of the two slides show assemblage similar to those of the samples collected off the slides areas, 3) generally samples of the NW slides are quite similar to those off the slide, 4) samples of the SE slides are dominated by organically cemented agglutinants in the living and in the total assemblage, 5) in both the Gela and Malta areas infaunal forams (Brizalina spp and Bulimina marginata) are present only in the shallowest samples while oxic species (Cibicides spp/Cibicidoides spp and Buccella spp) are present only in the deepest samples, and this is confirmed also by oxygen penetration depths in the sediment. Results seem to indicate that the SE slide represents an area somewhat still affected by sediment transport in comparison with the NW slide area. (literal)
