Finally a little bit of Spring popped up in our front
garden! Hard to believe as there are still mounds of snow and at least 3’ still needs to melt in our yard! This little bit of color after our record setting winter not only
cheered me but inspired me.
Kristen is home safe from her month-long Great Belt
Research Cruise in the Southern Ocean. The 2012 Great Belt Research Cruise: Exploring Phytoplankton in the Southern Ocean. An international
team of researchers left Durban, South
Africa on February 18, 2012 aboard the Research Vessel Roger Revelle and
arrived 35 days later in Freemantle, Australia, after collecting data and
samples as they crossed the Southern Ocean. Kristen worked primarily with the CTD equipment, and processed
the samples from the various stations in the on-board laboratory. The CTD
rosette is the primary water collection tool used on the cruise; CTD stands
for Conductivity, Temperature, and Depth, referring to the set of sensors
mounted on the bottom of the rosette.
One of the benefits of having a big sister as a scientist
is having her be able to shrink things in the deep blue sea and being able to
share it with your science class! On each of Kristen’s research cruises,
Kristen has shrunk, Styrofoam cups and even Styrofoam beautician heads for Gus
using the CTD. On this cruise the educational outreach coordinator included a
large mesh bag of cups from elementary school students on the East Coast that
were sent down to illustrate the effects of the pressure at 2 miles below the
surface. Fortunately for Gus his cup
made it but not so lucky for the other students…
On March 9 from Kristen while on the 2012 Great Belt Research Cruise : “All of this happened during our last deep cast, 4700 m, (4700 meters = 2.9204446 miles)
so it was a five hour cast. I sent down a bunch of styrofoam cups to
be shrunk, including the one I made for Gus. That one, plus the one I made for
me and the one I made for Jess, I put into a pair of panty hose that Cecila (a fellow researcher) donated for the cause. I tied them together, put a zip-tie in the middle of
them, and threw them into a larger mesh bag. We also attached another pair of
panty hose with cups with a ton of zip ties to the outside of the CTD, as well
as another blue mesh bag on the other side.
When the CTD came up (underneath an incredible display of
Aurora Australis southern lights), only the second blue bag, and the pair of
panty hose that I strapped to the cage were visible at first. The first blue
bag, the one with the majority of the student cups, was shredded to bits. Then, I saw
Mike's tie line in the distance, and I noticed something swinging from the
bottom of the CTD- it was the other pair of hose that had been INSIDE the blue
bag that ripped!!! Somehow, it wrapped itself round the frame,
without zip ties, and it still might have fallen into the
water as we were taking it out, but Mike had managed to hook it by accident!
Incredible! We are all really in shock about it- it really defies physics! So,
my cup, the cup I made for Gus, and the one I made for Jess all came out!
crazy, huh?”
Lucky for Gus!

And just so you don’t think this expedition was all fun
and games, here is a shot of the Revell as the stern descended into the trough
of a wave…
