4.21 Dutch gouge-auger core taken at Tahiti Beach in <strong>the</strong> vicinity <strong>of</strong><br />

Mallard Slough in January 1979. The approximate location <strong>of</strong> <strong>the</strong> core is<br />

shown in Figure 4.1. Note <strong>the</strong> pre-barrier Pleistocene surface (indicated<br />

by <strong>the</strong> arrow) at approximately 8.7 meters depth in <strong>the</strong> core. (Source:<br />

Stapor, pers. comm.) ................................................................................................................96<br />

4.22 Boreholes drilled in <strong>the</strong> St. Vincent Isl<strong>and</strong> vicinity. Inset map shows<br />

<strong>the</strong> location <strong>of</strong> <strong>the</strong> three cores. The pre-barrier Pleistocene surface appears<br />

in <strong>the</strong> two St. Vincent boreholes (Holes IL <strong>and</strong> IM) at approximately 22<br />

feet below MSL (6.7 meters). (Source: Schnable, 1966).........................................................97<br />

4.23 Line A-A’ represents <strong>the</strong> location <strong>of</strong> <strong>the</strong> topographic survey transect<br />

across St. Vincent Isl<strong>and</strong>. That pr<strong>of</strong>ile is shown in Figure 4.24. The<br />

pr<strong>of</strong>ile follows isl<strong>and</strong> Road 4. Line A-A’ also represents <strong>the</strong> location <strong>of</strong><br />

<strong>the</strong> GPR survey transect across St. Vincent Isl<strong>and</strong>, which is shown in<br />

Figures 4.27 <strong>and</strong> 4.28...............................................................................................................98<br />

4.24 North-south topographic pr<strong>of</strong>ile across St. Vincent Isl<strong>and</strong>, along Road<br />

4. North is to <strong>the</strong> right. See Figure 4.23 for pr<strong>of</strong>ile location. The blue line<br />

represents <strong>the</strong> transect conducted by Stapor <strong>and</strong> Tanner (1977) (referred to<br />

as “Stapor Survey”. The green line represents <strong>the</strong> road <strong>and</strong> <strong>the</strong> red line<br />

represents <strong>the</strong> survey conducted during this study (referred to as “Kish<br />

Survey”). Vertical exaggeration is 200 x………………..………………………………….…99<br />

4.25 Topographic pr<strong>of</strong>ile across <strong>the</strong> beach ridges located at site SVI 009.<br />

The ridges are located on isl<strong>and</strong> Road 4, <strong>and</strong> are part <strong>of</strong> <strong>the</strong> topographic<br />
