Well, I found a way to get the weather information in spite of the fact that it's not back on the intranet yet so I should be able to provide this information daily
Today was a productive day. I feel that I've worked out most of the bugs in the assay procedure and can have confidence in my data. So today I ran the first "real" experiment. I collected 10 tube feet and placed each one in a special sealed vial. These sat in a cold ice bath for 4 hours after which I measured the amount of oxygen contained in the sea water of each vial. If the tube feet tissue is consuming oxygen then the amount in these vials will be less than the oxygen concentration in the controls (only sea water). The difference between the two groups represents the amount of oxygen used by the tube feet only. In this way I'll be able to learn the amount of oxygen each individual tube foot uses in a parcticular amount of time.
I need to obtain two additional kinds of information on these tube feet. These are measurements of the amount of protein and of an enzyme called citrate synthase. It was too late to do these experiments today so I froze the tubefeet and will be able to use them tomorrow.
I'm calling it a day now. The people in my lab are showing the movie, "Amazon Women On The Moon" and I'm late already! Tomorrow is another day.
