trench. Table 4.1 lists the samples collected at the site. Figure 4.7 shows the location of all samples that were collected at this site. SVI010 This site is located on Road 4, approximately 120 m north of the intersection of Road 4 and Road A. The site was visited on May 5, 2005. A trench was excavated and 1 push core and 3 granulometry samples were collected for analysis. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. Figure 4.8 shows the location of the samples that were collected from this trench. SVI011 This site was visited on May 5, 2005. The site is located on Road 4. A trench was excavated in the crest of the first ridge north of the beach. This ridge represented one of the youngest ridges in ridge set K. One push core for OSL dating and two grab samples for granulometric analysis were collected from the trench. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. Figure 4.9 shows the samples collected from this site. SVI012 This site is located at the intersection of Road 5 and Road B, within ridge set G. The site was visited on May 5, 2005. A trench was excavated and one push core for OSL dating and 2 grab samples for granulometric analysis were collected. The trench showed landward dipping features that would suggest that the feature being sampled was a dune rather than a beach ridge. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. Figure 4.10 shows the trench excavated at this site. SVI013 This site is located 143 m north of Road B on Road D within ridge set H. The site was visited on May 5, 2005. A trench was excavated and 1 push core for OSL dating and 2 grab samples for granulometric analyses were collected. The trench showed landward-dipping features that indicated that the feature was either dune decorated or was entirely dune. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. Figure 4.11 shows the trench excavated at this site. SVI014 This site is located south of Insulator Road, within ridge set F. A trench was excavated on May 5, 2005 and the site was re-visited the following day. An overnight rainstorm had 59
collapsed the trench. Therefore, a vibracore was collected in place of push cores or granulometry samples. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. Figure 4.12 shows the sample site. SVI015 This site is located within ridge set B, 28 m west of the intersection of Tahiti Beach Road and the last road before St. Vincent Point. The actual sample site was approximately 3 m off the west side of the road. A vibracore was collected on May 6, 2005 and then discarded because of a high abundance of shells in the bottom of the core. The absence of oysters indicated that it was a natural shell deposit and not a midden. A second attempt at collecting a vibracore was made. A small hole was dug to get below the shell layer and a vibracore was collected at the bottom of this hole. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. Figure 4.13 shows the sample location. SVI016 This site is located, within ridge set D, on Road 5 just south of the intersection of Road 5 and Road H. The site was visited on May 6, 2005 and a vibracore was collected. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. Figure 4.14 shows the location of the vibracore. SVI017 No sample was collected at this site. Once the trench had been excavated it was evident by the sedimentary structures that the site represented a dune and not a beach ridge. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. SVI018 This site is located 0.6 km from the intersection of Tahiti Beach Road and Road I, within ridge set C. The site was visited on January 6, 2006. A 60-cm deep hole was dug and a vibracore was collected from the base of the hole. Approximately 1.5 m of sediment was recovered. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. SVI019 A push core was collected from the beach surface, within set L on January 9, 2006. The sample represented a potential zero-age OSL sample, having been collected from the active part of the youngest developing ridge on the island. The site is located 100 m south of the end of 60
