About the black "squiggly" stuff. We found a length of it and videoed it up close during Niku VII. Somebody aboard KOK recognized it as a type of gasket material commonly used aboard ship and showed me a handful of it. Clearly the same stuff we saw in the video. Now I wish I had taken time to photograph and document exactly what it is, but at the time it was just "Okay, so we don't need to worry about that."
