We Blogged It!
Just off the northern coast of French Guiana
There are no new updates to report tonight, which tells me that the science teams are very busy at work! Having spent a month in the Amazon Plume with the ANACONDAS Team 2 years ago, I know how every precious minute is focused on the sampling and experiments. This cruise is much shorter so it’s important to use time wisely!
So, I’ll take this time to introduce you to some of the other science teams onboard.
Dr. Rodrigo Leão de Moura is an Associate Professor of Marine Biology at the Universidade Federal do Rio de Janeiro, Brazil, and is the Co-Chief Scientist with Dr. Tish Yager.
The Moura Lab at UFRJ focuses on benthic habitat mapping and conservation planning, as well as on functional aspects of reef systems such as the interplay between water chemistry, fish, macroalgal, coral and microbial assemblages. Onboard the 2012 R/V Atlantis cruise he will survey benthic assemblages in hard bottom patches off the Amazon River mouth.
Student Nara Lina Oliveira is an MSc candidate at the Ecology and Conservation Program of the Universidade Estadual de Santa Cruz, Brazil, under advice of Dr. Rodrigo Moura. She works with benthic ecology and will be engaged in the survey of the hard bottom patches off the Amazon River mouth.
Nara shared a fun fact with us: “I love practicing Capoeia and I fell in love with it since my first class in 1997. It's a kind of martial art created in Brazil mainly by descendants of African slaves with Brazilian native influences. It is known by quick and complex moves, using mainly power, speed, and leverage for leg sweeps. It combines elements of percussion instruments, songs, clapping, fight and acrobatic movements including summer salts. This combination can put you to a trance when watching a "Roda de Capoeira" (A circle of people watching a game of capoeira where two players are in the middle interacting with defenses and attacks movements).” Wow! I’d like to see that!
Update on the “head” sent by Redd School students via Joanna Green:
The head and other decorated Styrofoam cups were attached to the Multicorer (for sediment cores) and lowered to a depth of 4790m. The current maximum diameter is now 28cm, height at maximum is 13cm.
According to Joanna “it is more dense but mass should be the same”. The starting diameter of the head was 66cm, with a height of 34cm. Unfortunately, we didn’t calculate the mass beforehand.

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.
