Note: In this view, the black area is either where land is located, or it represents the margins of the survey .
(2d capture of entire area from south - 1 x magnification ). Bentick Island appears at the top of the picture. Great Race Rocks, where the light station is located is the large island in the center of the picture. Shoreline margins are not yet accurate. The present boundaries of the Ecological reserve are more or less the outer limits of the red area at 36 meters.

The second image is a view from the South looking Northward. Colors toward the blue scale are representing depths of almost 100 meters.
( 3d capture of entire area from south : 1x magnification -3 x vertical exaggeration)
We hope to add further interpretation to the pictures , but at this stage they represent a significant step as the first layer of information on the seabed.

These projections represent three dimensional views looking toward Race Rocks from the North West underwater direction. |
