Many of these processes occur so rapidly and unexpectedly that they have daunting consequences.
To constrain the timing of the retreat of this ice, we are using a technique known as cosmogenic nuclide dating.
I collected the samples in the field in 20: Having collected the samples in the field and received funding to run them, I went up to the Scottish Universities Environmental Reserach Centre (SUERC) laboratories in East Kilbride to start the process!
As 10-Beryllium and 26-Aluminium preferentially build up in quartz, the aim of the first week was to crush down the samples and extract as pure quartz as we could.
This provides an ideal method for determining when a glacier retreated from a region, hence exposing the ground beneath.
Technological developments in the last few decades have allowed more precise measurements of their concentration in terrestrial rock samples and this dating technique is becoming increasingly popular.

Here is an example of a Be-10/Ne-21 two-nuclide diagram from one of my papers: Here I have put Ne-21 (the longer-lived nuclide) on the x-axis and the Be-10/Ne-21 ratio on the y-axis. I think no matter what the nuclides involved, you should always do it the same way as is commonly done for Al-26/Be-10 diagrams, so that burial goes down.
