My Experiments

Measuring the amount of oxygen the animal uses

Clams in the respiration chambers (glass jars!)

Measuring the oxygen content of the water with an oxygen sensitive foil inside the jar

The data feeds into the computer generating graphs of oxygen consumption

I'm researching the metabolic rates of Antarctic marine animals. Animals in Antarctica are very slow growing and have low metabolic rates. Some of the animals I'm studying are over 40 years old! To measure their oxygen use, I keep them in glass or perspex containers for about 6-8 hours and measure the amount of oxygen removed from the seawater over that time.
