Still working at Lat 6.39 N Lon 48.33W

 Adriane finally tagged Chief Tish today for a few minutes out of her really busy days. Being a PI (principal investigator and Chief Scientist) AND running her own experiments are a big juggling act. Tish confessed that she finally got 7 hours of straight sleep for the first time since the cruise began. I know from personal experience that sleep is not always an option when there is so much to do within the time allotted for the science!

 Tish says most of her experiments are at the point where they are finally getting to work so she doesn’t have big results to report, yet.

The one result she does have is that the bacteria she is running experiments on with amino acids seem to be using them primarily for growth rather than respiration. She is now running an experiment where she is feeding them glucose. More on this soon!

 Tish also describes this trip as less stressful than last year, due to more experience. She also doesn’t miss the SOMMA- the piece of equipment I worked with that gave us so much pain last year! Lastly, the Captain and the crew are “excellent and very engaged with the science”.

 Adriane adds: “The chefs are both extremely nice and thoughtful with special diets, etc. and we have had a lot of cake, which I particularly like. “

 We’re already nearing the halfway point in the cruise! Where does the time go???

BTW, I've added some more pictures of the sediment coring :)

 Cheers, Lollie

Question of the Day

  • Do the bacteria in the water make us sick?

    Only a few of them.  Bacteria are in every habitat on Earth, growing in soil, hot springs, radioactive waste, water, as well as in organic matter and the live bodies of plants and animals. Bacteria recycle nutrients, with many steps in nutrient cycles depending on these organisms, such as nitrogen fixation.
