 A new post from Chief Scientist Tish:

 "The team onboard RV Atlantis has had a banner day.  Following our crossing of the equator last night at about dinner time, we started our day at the mouth of the Para River (southern channel of the Amazon near Belem) and have now worked our way out to the blue waters of the equatorial Atlantic.  We are in aqua green waters on the Brazil continental shelf, just south of the Amazon River outflow."  

"Two major findings to report:  

 1.  We found DDAs today, blooming on the shelf, south of the outflow of the river (in 36.5 salinity water).  Some serious rethinking about these organisms will now be required, I think. 

 2.  Rodrigo has located one of the coralline algal reefs he was searching for, at about 38 m depth on the shelf offshore of the Amazon mouth.  He and Nara are busily processing two successful dredges right now, while we steam out a bit further toward the shelf break to see if we can find more. " 

 "We just completed our last hydrographic station at mid-day today. We have a bit more to do tonight and will then spend about four days steaming north to Barbados, sampling underway.  Everyone is exhausted but energized by such an exciting day!"  

  "Congratulations to this extraordinary international team of dedicated scientists!  The winds have calmed and we should have smooth sailing home.

 Cheers to all, Tish"

Cheers Indeed ANACONDAS!!!    I'm happy to report that web issues seem to be resolved. I have posted some of the images that should have been up with previous posts- thanks for your patience!

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.
