Poor sample recovery severely limited the number of samples obtained at Sites 1110, 1111, 1112, and 1113 for microbiological analysis. Eight samples were obtained from these sites for shipboard microscopic determination of total bacterial populations: four from the surface core in Hole 1110B (0-4.5 mbsf), three from Hole 1111A (69.2, 117.2, and 127.3 mbsf) and one from Hole 1112A (1.5 mbsf). In addition, three whole-round samples were taken from the mudline core at Hole 1110B for shore-based experimentation. No samples were recovered for microbiological analysis from Site 1113.
Bacteria were present in all samples examined (Table T14; Fig. F25); their numbers decreased rapidly with increasing depth. Near-surface bacterial populations at Sites 1110 and 1112 are again similar to those at other sites with similar overlying water depths and near-surface organic carbon concentrations (see Table T11 in the "Site 1108" chapter), and their distribution lies within the 95% prediction limits described by the model of Parkes et al. (1994) (Fig. F25).
