Can you comment the first line out? Just to see if that is the culprit for the failures we are seeing?

Looking at the Binderbot check results, the error comes from 01_ecco and transform_mld_coordinates. The 06_metrics notebook renders fine.

Can you get a cluster via dask gateway. That might also contribute to some errors.

I am not sure what is going on. My best guess for now. The first notebook failure is some temporary glitch (https error) and the mld notebook failure might be due to the install command you still had in the notebook? If fixing that doesnt help, we will need to dig deeper into what has changed on the docker image recentyl

Hmm I'm not sure if this affects anything, but to update the notebook I run it in Pangeo Cloud, then download it to my computer so I can then push changes to this repository. Is there a way to push directly from Pangeo Cloud?

Oh yeah for sure. You can open a terminal on there:

Just click on the big blue + button up top and choose Terminal on the lower left.

This is looking great. I really liked how you show the big result up front (grid.average(uo) works) and dive in to all the effort it took to get it to work.

Some higher level comments to make it even more awesome.:

1. I think you should show 1 or maybe 2 years of data so people can see the seasonal pattern. Right now it looks very noisy.
2. I think you need a simple 4-cell version of this figure with T-points and u-points to make it really clear to the audience what needs to happen. you could illustrate what "averaging" or "interp"-ing does using a version of the 4-cell image too
   
3. The "setup" (reading, subsetting, plotting) is a little long. While presenting I think you may want to do this quickly mostly highlighting "this is a regional subset of the global model and I want to analyze it".

Great! :)

1. Alright, will do.
2. Do you mean a graphic of 4 boxes with the dot in the middle for temperature, and arrows at the sides for u-velocity? Will this be embedded in the notebook as well? Maybe before the cell where I calculate mean SST time series?
3. For sure, I will just go through that quickly. The main focus will be showing how calculating u-velocity average took longer code before, how much shorter it is now, and the part at the end where it shows how this is made possible.

Yes. You can highlight a "u cell" and a "T cell" and show that areas are potentially different.
