Lisa is shaking the mixture of the sample, standard, and DCM. She is also wearing the proper attire and containing the sample inside the vent-a-hood.
In this picture Becka is cleaning the glass plate with DI water to clean off the salt water residue.
This picture is off of the dock of the first house we would take samples from. This was on a semi-choppy day meaning the water was a little rough and the micro-layer could have been disturbed.
This is Lisa and Becka leaning over the dock to collect a sample at the first location.
