Summary of the last four days temperatures in the pond. After a warm day the water’s got a bit chillier again.
So why am I interested in the water temperature?
Mainly I’m doing it just to understand how the temperature changes – I don’t think measurements like these have ever been made before in a garden pond.
It also affects the amount of oxygen in the water – the colder it is, the more oxygen dissolves in the water – though as I’ve noted before this isn’t such a big deal as pond dwellers are adapted to natural variations in oxygen concentration – so they’ll be used to the increase in the dissolved oxygen as the water cools down in autumn and winter.
We’re always told it ought to be slowing things down too – though so far there’s not much sign of this.
