The SAIC gravity corer included core barrels consisting of a 1.5 m (5 ft) section of 

 Schedule 40 PVC piping (10.2 cm or 4.0 ID) and included a stainless steel core cutter and 

 core catcher at the end. Upon collection, the PVC tube was cut, plugged, and capped to 

 prevent movement of sediments within the core during transport and storage. The postcap 

 survey cores were transported back to the GSO laboratory facilities and refrigerated during 

 storage. 



At the GSO, the postcap sediment cores were split, visually described, and sampled 

 for grain size, as well as for mineralogical and microfossil composition. A total of 92 

 samples (2.5 cm plugs) were taken from the nine cores and placed in pre-cleaned plastic 

 containers. Forty-six samples were sealed and forwarded to an independent laboratory for 

 grain size analysis. The remaining 46 samples were covered with a buffered formaldehyde 

 solution for meiofauna preservation and sent to the micropaleontology labs for processing 

 and analysis.
