Running lines

This is what we had come to do, running survey lines so we could see what was under the bottom of the sea.

The boat us currently under the point to the extreme right of the screen, and the seabed is 1973 metres down, and as you can see had been much deeper earlier on the survey run.

 

We can see strata below the seabed, but in two places to the right of centre, there appears to be two areas of gas forcing the seabed up and obscuring the data; possibly there is oil below.

 

The data is being collected by a hull mounted pinger and processed by a Knudsen, which is specifically for deep water surveys. At one point to the north of Sulawesi, the seabed was six and a half kilometres down.
