Very happy news from Chief Tish this morning!!

“Greetings from the RV Atlantis!”

“This morning we crossed into Brazilian waters for the first time!  The winds are fair and the seas are calm.” 

“All is well.  Atlantis is a great ship, the captain and crew are very supportive, and the science team is outstanding.  We have completed four process stations as planned on our way south to Brazil from Barbados.  Following a few snafus, all equipment is now functioning well.  Our first station in Brazil will start near ~ 4°49'N, 49°25'W later this morning. “

“We have sampled the plume with salinities ranging from 36 to 16, so far, with surface pCO2 ranging from near-atmospheric down to 150 ppm.  Phytoplankton assemblages have been quite diverse, including significant Trichodesmium alongside coastal diatoms, and the zooplankton are abundant.  The water is green, but clear.”

“Our team in the river is mobilizing and will be sampling nearby in the lower reach of the river within the week.”

“Best wishes and many thanks to everyone ashore for your support of our endeavor!

Cheers, Tish”

Laurie Chong adds that the plamkton sampling is in full force. Using the'Moc' (MOCNESS), this special net allows the plankton team to capture samples of zooplankton from different depths to look at the community structures. If they sample at noon and midnight, they can track the daily migrations of different species.

And speaking of Laurie….HAPPY BIRTHDAY!! What a great way to celebrate -in Brazilian waters!!!!

More news as it happens!

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.
