Davis Strait 18 Oct 2011 crushing cups

We are now south of Davis Strait in the northern Labrador Sea.  The air temperature is up to a balmy 3-4C and it no longer feels like the Arctic. Maybe the humidity is higher. But I did not check the humidity when we were further north. 

We just completed a CTD station in 1500 m of water. It took about an hour to go down and back. The maximum speed of descent/ascent is 60 m per minute.  Later tonight (or this morning) we will do a 2200 m station which will be a record for me. I am a continental shelf guy. It is hard to imagine doing 6000 m stations.

As a school project event we are doing every ones favourite ocean activity - compressing styrofoam cups.  My colleagues brought a large number of cups that have been decorated by elementary school  kids.  We put them in a mesh bag, tie them to the CTD, and send them down into the depths.  The compressed cups are the taken back to the kids. Very educational I am sure.

The 2 cups in the back are the regular size, the two in the middle went down to 1000 m and the two in the front went down to 1575 m (just a few minutes ago).

  1. When I first read about the styrofoam cups I thought you guys were crushing them yourselves :P I wasn't sure how that was going to be educational for the kids. It looks like a very cool school project though, they shrink so much!

  2. I have now revised the text to explain what we do.
