The other day in the lab, in preparation for a collection day this weekend, there were more dishes to do...

... more of this...

admittedly, I'm a bit of a self-diagnosed OCD

... and this...

but it makes for better photos

... and sharks!

I also had the opportunity to observe (and try my hand at) the end stages of a previous experiment. Several core samples had been dug up and were being carefully incubated. Water from the cores were taken at various times to measure the changes in nitrogen concentration (in two of its common forms) over time. I was able to get my hands 'wet' and filter a few of these samples.

Shall We Start at the Beginning?

After a quick tour of the facilities, I was set upon the task of acid washing the lab equipment and glassware. Everything that is used for the collections and experiments on this project must be completely free of nutrient contaminants so as not to give any false readings in the data.

The process involves a thorough scrubbing, a rinse under deionized water, several hours submerged in hydrochloric acid, and another three rinses (again, with DI water).

In practice though, this was much like doing the dishes at home... with hydrochloric acid.
