This is a remarkable image and was only,
honestly, acquired through blind luck. After completion of the southern line, Heron turned to the north, crossing just behind the head of the flow and then proceeded to image the body of flow as the Heron steamed back to the west on the north side of the channel. The Heron is running at ~ 3m/s and the flow is moving at about 2m/s. About 3/4 of the way back along the channel, the Heron overtook the head of the flow. A separate page is being prepared that shows the water column imaging as the body of the flow was examined. |
