Tamara Bartholomew - The Serious Science on the CSIRO Southern Surveyor day 3 It is becoming more noticeable that the air and ocean is cooling as we head south. Overnight the boat picked up speed and today we were able to complete a station at 1400, it was nice to be outside for a change. As a part of the afternoon team I can say that the 2pm station appeared to go well. All of the XBT's had a good signal and worked well. The CTD did not get stuck or tangled and the CPR (continuous plankton recorder) got a new cassette put in it. The CTD has different tanks carrying water samples from different depths. 3 tanks were chosen to obtain samples of oxygen and salinity. Chlorophyll samples are taken from different depths and put through a filtering system. The CPR Silk cassettes needs to be changed every 450 nm but was changed at approximately 300nm. After dinner we were able to do some chlorophyll measurements in the samples that had been refrigerated for 48 hours samples. Now time to relax and watch a movie as the next 2 days may be quite busy.
