Shells deployed in 1993 1995 by SSETI were selected to have relatively little degradation of the outer shell surface, thereby minimizing the differential between these two surfaces.
This tendency for mussels to deteriorate more rapidly was already apparent in SSETI deployments after two years (Staff et al.
Whereas SSETI data do not directly confirm the efficacy of this approach, the comparison of shells on the visually similar Bahamian EODs suggest that the carbonate chemical milieu varies considerably between transects AA and BA.
Analysis of SSETI deployments does not permit discrimination of the causative factors behind the development of a dissolution surface on the shell.
In SSETI deployments, deterioration of the inner shell surface did not proceed in step with deterioration of the outer shell surface.
SSETI recovered experimental arrays at 41 locations and consolidated these into 24 EOPs based upon visual and a posteriori statistical evidence.
The SSETI deployments considered here are, therefore, unusual in having been on the seafloor for a substantially longer period of time.
The deployments recovered by SSETI after eight years on the seafloor are themselves not particularly long.
(2002) summarized the early results of SSETI. "Overall (after two years), most shells deployed at most sites had relatively minor changes in shell condition.
Thus, at a coarse level of resolution, the taphonomic processes active at SSETI sites were accurately assessed after two years of deployment time.
SSETI continues and longer-term deployments may yet be available to evaluate the verity of ratiocinations reached herein.
Although the number of SSETI sites is relatively large and the types of EODs diverse, the full ambit of preservation is unlikely thereby encompassed.
