1-10 on one hand and other useful cultural exchanges

One of the things that I am really enjoying about this expedition is that half of the scientists in the science party are from China. This collaboration between China and the IODP will hopefully continue to build over the years as China builds more deep sea drilling research vessels. 

Curiosity and Collaboration

We are getting closer to the end of the expedition. The scientists are preparing and presenting their post expedition research proposals and sampling party requests. This is a time of both curiosity and collaboration. 

Science on the Vessel - Video by Shuhao Xie

Our education officer Shuhao Xie made another great short film called Science on the Vessel. It gives a quick glimpse in to the uniqueness and history of the of the IODP program through the lens of Hans-Christian Larsen our Co-chief for Expedition 368. 

Enjoy! - https://youtu.be/cVaIkKKwdXk<

Thruster Pod - Sat, May 20

This is a single thruster pod that houses two propellers - remember these are controlled by the dynamic positioning system, and hold the ship’s position over the drill site. It is not easy to sense how steady the ship is unless you have a reference point, e.g., looking at something that is also steady. The problem is everything is on the ship or attached to it and therefore moving with it.

“Arduinos & Raspberry Pis” – Fri, May 19

Building cool circuits using microcontrollers or Arduinos (to the right in the pic) is one of the cool things we are doing in our spare time onboard the JR. I now have an idea of how to set these up as seismic sensors at my university to measure the motion of different stories in a building.

Expert Learners

"I am not an expert but I can learn." Fabricio Ferreira, one of the Micropaleontologists replied during a question and answer after his presentation at a crossover meeting. This was in response to a question about reporting more about the agglutinate species of foraminifera, (a.k.a.

Dumbo Octopus caught on film!

Yesterday the re-entry camera was coming up from the bottom of the ocean and it caught footage of a Dumbo octopus Grimpoteuthis sp.. These unique cephalopods live in the deep sea. Their ear like appendages flap as they swim hence the knick name!  It is very rare to see them swimming in the wild. We feel lucky to have caught one on film!

No anchors, a needle on a string, we need thrusters!

If you want to approximate the difficulty of drill hole re-entry with the drill string you could try the following set up. Warning: You may have fun doing this and understand that this is only a model - A simplified version of the real challenge out at sea. 

Thermal Conductivity – Mon, May 15

One of the rock properties we measure in the “Physical Properties” group, is thermal conductivity. This is a measure of how well the sediments or rock conduct heat and is used to determine the heat flow, an estimate of heat transfer out of the cooling rock layers. I carry out the measurement in different ways depending on whether it is sediment or rock.

"Core on Deck" - The Man behind the voice

>It made me so happy to finally meet Glen this morning. He is locally world famous here on the JR. It is kind of like meeting David Attenborough or Morgan Freeman. He has been the navigating voice of this expedition so I got his autograph!<
