Robotics & Autonomous SytemsWet feet for our maritime swarm vessels, as they perform their first trials in the framework of the project #MCM_MULTIMETER and #DFR_MAIWA. Keep an eye on our pages for future updates.
lilafischJoin us for one last dive with the @MARUM ROV QUEST,
today we will map a black smoker, to see the changes that happened since we last visited it a few days ago. Then we will transit to a skeleton we found two days ago.
MARUM LiveDive - Expedition Livestream
Another dive with the @MARUM ROV QUEST, another live stream π
You might recognise some of the sights. This dive we will do a lot of mosaic work (note the flashing in the rear view cam) and we will try to take some push cores so our foraminifera scientists can get some samples π€
There is also a small mystery we are trying to solve, I think that is all I can say π€« you might be able to hear it from the science conversation

We are taking another sample from an amazing black smoker, at over 300 degrees C! The wire is needed to control a motor at the start and end of the sample taking procedure, the rope is there to make sure there is no tension on the wire, and the markers are there to help the pilots make sure the cable is not damaged while moving the device with the arm.
The view of the hot water, the structure that were formed and the black smoke is amazing!

As you can see, there is little to see. It is amazing that we can find the comparatively small vent systems. It is important that the acoustic positioning system is accurate, otherwise we are looking for a needle in a haystack.

We are now doing a longer transit to another site. The site is ca. 40m less deep, the pilots are following the terrain, my colleague in the workshop container is adjusting the umbilical with the winch and the ship is moving with us as well.
Have a look at the lookdown camera, this is one of the most important cameras I use during flight.
The current sampling tool, βKIPSβ has a temperature sensor and an inlet at the tip that is being held into hot fluid. The inlet is connected to a pump that sucks water into a sampling bottle and the temperature sensor is giving us life data. One sample takes ten minutes, but the area with a high enough temperature is very small, so the pilots have to keep the arm very still while sucking up 200deg C hot water.

And the stream is now live!
As far as I know, this time the audio is the conversation between a larger group of scientists in the conference room and one of the two scientists who are with the ROV Pilots in the control container.

After waiting out some waves unsuited for ROV deployment and recovery, we are preparing a dive again tomorrow π

The audio in the live stream today is the conversation between the pilots and the scientists, there are some interesting moments where you can get an understanding of the planning that is happening while the camera view is relatively boring.
Greetings from another break, after pulling three Niskon bottle triggers with the robot arm π¦Ύ
After three types of fluid sampling, my colleagues are now mapping the black smoker visually for 3D reconstruction.
