The choppy waves due to gale force winds made the multibeam data really messy, so it’s for the best that we shut it off as we approached the Brazilian EEZ. The magnetometer was taken out so we could dredge yesterday, and since we’re running for cover near Brazil, there’s no point in feeding it back into the water. With “messy” multibeam we can’t do much, as it means that there are a lot of bad pings and false/misleading data. The multibeam normally shows us a little map of the seafloor as if we were looking at it from an angle, but the messy data shows up as a concave curve—we’ve taken to calling them “smileys”.
