Daily Update: Honey, I shrunk the cups
By Amy Nevala
Bob Collier and Charlotte Meredith brought an unusual catch
in with the CTD sensor this afternoon - miniature Styrofoam
cups descended into the Indian Ocean this morning the size
of regular coffee cups, but as they encountered the increasing
pressure down to depths of 3,300 meters (almost two miles),
they shrunk to the height of golf tees.
eight-year-old daughter, Elise, and her third grade class at
Harding Elementary School in Corvallis, Oregon decorated 28 Styrofoam
cups in bright fish, happy faces and American flags. Bob will
deliver the mini-cups to the class, along with a lesson on ocean
pressure, after this expedition.
Despite successes with the cups, today we failed to find a hydrothermal plume.
Bob said this is somewhat of a puzzle, since last week we saw signs of a plume
after sampling here.
We think its due to a change in bottom currents, said Bob.
The plume may now be flowing in another direction, like smoke from a chimney
shifting in the wind.
This evening, we have more information to help locate the plume. Despite 15 to
18 foot swells, Captain AD Colburn and his crew retrieved the current meter from
the ocean today. The instruments data show that currents near the seafloor
in this area flow south at speeds of about 1/4 knot.
This means that if I see I plume, I will look north, or upstream for its
vent source, said Bob.
we will use the CTD for more measurements and water sampling,
factoring in the southern current flow to close in on possible
plume target areas. When we get close enough and when the seas
subside, we will lower cameras and other tools to pinpoint the
yet-unidentified hydrothermal vents that are the sources of the
Dinner tonight brightened any damp moods about the high seas. Geologist Dan Fornari
simmered and stirred a garlic-and-basil-laden Italian feast. Pesto with crunchy
pine nuts, a meaty Bolognese sauce, and a spicy marinara olive sauce over pasta
topped the menu, chased by a rich chocolate mousse that draped our tongues like
my Moms recipe, said Dan It has become a tradition
that I cook on every cruise I go on. I do this as a small token
of appreciation for all the hard work of the ships crew.
Happy eaters exited the galley rubbing round stomachs
and mumbling intentions to get on that exercise bike first thing tomorrow.
