Now in the golden olden days of oceanography this would have involved a pile of people up on deck with a long rope and a rock tied to the end. Rock is then lowered into the water, regular marks on the rope let you know how deep it is when the rock hits the bottom, the rock is retrieved and the process is repeated over and over and over again.
The downside of this process is that it's incredibly labour and time intensive and gets relatively few results over time. However the notable upside is that there would be something to photograph. There would be action, drama and excitement. It's also a process that's really easy to understand. It's easy to communicate and it's easy to trust, because it works. No such luck these days. Whilst the science has improved greatly the ease of communication has diminished significantly.
It's incredibly detailed, we can get great data going at 10 knots (I know this to be a speed faster than 8 knots but slower than 12 knots, couldn't give you more than that). We can get data while we sleep, eat and write blogs. And it's great. But it really isn't anything too exciting to behold in a blog.
The most exciting piece of drama I could provide is the occasional red flashing box.
Which is a shame. Because it is genuinely exciting!
So for all there is no photogenic excitement for you, there is some very awesome and beautiful data. Schmidt being the awesome Schmidt in a few months you'll also be able to download this data and have a play around too. Sniff around the sea floor and see what you can see! Sure you won't be the first person to see it, but you'll be up there on the list.
