Anthony gets to work
cutting the rocks from dredge 127. Each sample has to be cut
into various shapes for processing, and this is the saw we use to do
through the Clear Waters
clear water around Wallis island makes it easy to see the unique
shape of the Kilo Moana's bow.
With the main part
of the storm over, the Kilo Moana passed through some of the
remaining rain squalls as we traveled to dredge sites. Notice
how you can see the horizon behind us, but in front there is nothing
but a wall of rain.
Recovering the Dredge|
Recovering the dredge is always exciting. The increased swell
size made this recovery a little more interesting that most. Later
that day "heavy weather procedures" had to be implemented due to the
Julie and Allison
watch the spray from the large swells that the recent storm brought
about. They are standing on the edge of the fantail, just over the
Kilo Moana's starboard rudder.
Moana's Computer Lab|
evident in this quick panorama, even at 4 AM there is a lot of
activity going on. Whether mapping, dredging, or taking water
profiles, there is always something happening onboard the Kilo Moana.
The summit of the Nafanua volcanic
cone inside the crater of Vailulu'u seamount has abundant diffuse
venting with unusually thick microbial mats up to several cm thick.
These vents were studied during the PISCES5 609 and 610 submersible
dives that found that the volcanic rocks were very crumbly and
contain many crevices housed with an extreme abundance of eels.

Ed's Temperature Recorder
During PISCES5 Dive 612 two microbial sampling chargers, a site marker
and a temperature recording data logger were placed on the flanks
and crater rim of Vailulu'u. An additional data logger was deployed
directly in a crevice with hydrothermal venting (as evidenced by schlieren, bacterial mats and an elevated temperature near the
orifice of 8.1 degrees C). This data logger slipped into the crack
and could not be readily recovered. Video by Hubert Staudigel.
