It’s been a glorious day on board the James Cook for a number of reasons. First and foremost (for me!) being the successful deployment of the optical lander or, as it was dubbed after its disastrous first dive, the “Zombie Lander”. Our emergency repairs involved all kinds of creativity, including stealing the spring from a clipboard, but it was an amazing job – another testament to all the great people we have working on board.
And here it is – our first up close look at the bubbles escaping from the seabed. We even managed to catch a glimpse of some of the wildlife (it seems everyone wants to be on TV…).
The footage of bubbles will be analysed to determine their size, shape and speed. However, this is an incredibly time-consuming process that either requires a lot of computing or man power, neither of which we have much access to on the ship. So, in order to get some preliminary results whilst at sea, we’re subcontracting the work to a number of schools in England and Wales. Students will examine the footage and relay results to us next week during a live online Q&A session.
Elsewhere on the ship the benthic chambers were placed on the seabed before wrapping up a comparatively easy day for the ROV team. We’ve since left the area to let our fellow research ship Poseidon carry out some water column tests of their own but we’ll be back tomorrow to resume work.
