We finished our last CTDA research tool that is submerged in the water to measure conductivity (salinity), temperature, and depth. yesterday! It was another really deep
one—3800m. Afterwards we celebrated with chocolate (an increasingly rare
treat on the ship… as is fresh fruit). We also turned off the multi-beam
early this morning as we’ve left the continental shelf. We’re turning to
head back towards Hobart, but still have some Argo floats
to deploy. Although we’re finished collecting data for the trip, there
is still work to do. We have to clean up and pack up all the equipment
for shipping back to the U.S., and we can begin processing some of the data
on the ship. We have a good amount of time, as it will take at least 10
days of travel to get back to the dock.
Meet the Scientists: Ricardo Correia
BathymetryBathymetry is the study of the depth of water in the ocean. and Core Scientist on the Ship Master’s student in Geological Engineering at the University of Aveiro in Portugal.
What do they do?
Ricardo is one of the scientists that helps run the multi-beam
and processes the bathymetry data. Ricardo also assists in collecting,
processing, and analyzing any mud core samples we take.
How did he get where he is now?
Ricardo has always been very curious about the world. As a
child, he was given fossils which sparked his interest in geology. He
built up a nice mineral collection, which he still has to this day. His
favorite piece of his collection is a complete geode, which reveals
something beautiful hidden inside when it’s opened. In addition to
loving rocks and fossils, he also had a strong affinity for math. At
University he found a way to combine his love of geology and math
together in geological engineering.
Ricardo got involved in this particular expedition when his graduate
school advisor, who had worked with the Chief Scientist—Dr. Frank
Nitsche--recommended him to the position. This is his first Antarctic research trip.
Favorite part of the job
One of the things Ricardo loves most about science is that you get to
find new answers to problems and help people. In science you’re
constantly guided to new discoveries.
When not at school, Ricardo loves sports. His favorite sport is soccer
and he plays for his city team (and he's really good at ping pong as
we've learned on the ship). He also loves to do art, particularly pencil
