Hercules dive H1244 was a great success! Most of the dive consisted of visual survey transects from north to south, while zig-zagging east to west. After mapping and sampling the suspected beaked whale seafloor gouges, we relocated and mapped an Ottoman-era shipwreck with Chris Roman's still stereo cameras. These data will allow Chris to make a very accurate map of the shipwreck site in 3D.

Following the shipwreck survey, we continued our visual transect to the southwest to an area in which we found slickensides in 2010. Slickensides are smooth rock surfaces that are caused by two rocks moving past each other on different sides of a fault. Garrett Mitchell, one of our scientists and a graduate student at the University of New Hampshire, is interested in studying these features in more detail. We relocated the slickensides so that we can come back to this area in a few days to map them with Chris' sensors.

What's next?

During the predive check for H1245, the engineering team found that there was a problem controlling the thrusters of Hercules. They are currently troubleshooting the problem, hoping that they can find a solution soon. We will continue diving on Eratosthenes Seamount after a solution is found.
