Well said, Natalia! 👏🏼

We were super grateful to have you today, Chris! Thanks for coming along and sharing your wisdom and good advice ☺️🙏🏼

I am surprised they're not on Bluesky yet, but I am sure that will come soon!

If you're interested in getting your university involved with the journal, do reach out to Jack, the principal contact. His contact details are found through here: journals.ed.ac.uk/esjs/about/c...

If you haven't come across the #ESJS yet, it's an @edinburghdiamond.bsky.social hosted journal, specifically designed for undergraduates to publish their science, and for PhD students to gain experience in reviewing!

It's open to most universities in central Scotland, but is growing fast!

It’s a beautiful place!

Do you need some WD40?

You are correct - the atmosphere also has 6-year periods - they co-exist with the ones we see from the core (which we would expect to exist, as per ex. Mound and Buffett 2003).

I can recommend this recent review that interprets all these signals holistically.

The jury is still out as to why, but I suspect it arises from the gravitational coupling between the inner core and mantle

After that, the 6 year oscillation is still clear. It is well acknowledged that such a signal exists (see, for example, Holme and de Viron, 2013;Nature, or Rosat and Gillet, 2023;PEPI).

We remove the tidal contribution from the signal using the IERS reference tides, which do a very good job. We also clean the signal of atmospheric and oceanic contributions to length-of-day.
