Most of the oxygen measurements I’ve described so far (for example the under-ice measurements) have been near the surface – say the top 5 cm of water. Though it’s worth saying that in the shallow ponds this is one-fifth of the total depth!

We’ve also done measurements at top, middle and bottom which, as you’d expect, usually show a drop from top to bottom.
