along the transect, 800m terrain):
Yellow line segment indicates a low oxygen zone at the shoulder of a small 50m embankment.

Easy to visualize the midwater transects and the low oxygen zone (yellow & white colors). The white lines show the horizontal and verical scale. The vertical line is 4 times longer than the horizontal because we have 4x vertical exaggeration.
Same dive as above, but with terrain (timeslider set to about 32 minutes earlier in the dive):
Same dive, 12 minutes later than upper image, zoomed to within 50m of Ventana.
Screen grab taken before software was written to include time time readout on the timeline slider and before we could map measured water properties to the ROV trackline. It shows the use of transparent terrain. This is from Expedition 1999273:
Sample screen shot from R/V Point Lobos expedition on 1999273 (Ventana dive #1684). Terrain is shown with 25% transparency, notice how you can see the ROV model and dive track go below the surface. The vertical bar on the left is a time-control slider. You can click and drag the blue ball to control the positions of the ship and the ROV according to the navigation records. The red rectangle on top of the slider control can be clicked to turn on and off the replay. When it's on it will be green and the Ship and ROV models will move along their tracks at a normal (un-accelerated) speed. All of these visualizations are generated with a 4X vertical exaggeration.
