Today has been a busy but routine science day. I performed another set of experiments to see the effects of temperature on tube feet respiration rate. This time the tube feet were kept at a temperature of 2.5C. degrees for 4 hours. I then measured their consumption of oxygen and later determined the amount of protein.

I'm running out of time and am a bit concerned about how many more experiments I will be able to get done before I leave McMurdo and return to the USA. If the weather holds we will be on the ice all day tomorrow and a helocopter trip to the ice edge is planned for the following day.
