A scientific research vessel for seafloor
exploration and observation
JOIDES Resolutionoverhaul and enhancement
New to the core After major refurbishment, the JOIDES Resolution returns
The JOIDES RESOlutIOn is a dynamically positioned drillship
and a floating laboratory that can drill down more than 2,000 meters into the seafloor and in waters as deep as 7,000 meters.
On board the JOIDES Resolution, scientists from all over
the world will lead expeditions aimed at the deep biosphere
and the sub-seafloor ocean; environmental change, processes
and effects; and solid earth cycles and geodynamics. These are
the principal science themes for the Integrated Ocean Drilling
Program (IODP), the international endeavor for which the
new and improved JOIDES Resolution will primarily work.
Already a 20-year workhorse of scientific ocean drilling, the
JOIDES Resolution has been completely overhauled, resulting
in a new U.S. drilling vessel for IODP. Laboratory space has
been increased by 34% and is designed for greater efficiency
in handling cores. There are 16 additional berths and all
staterooms are double occupancy. Drilling capabilities
and ship stability have been enhanced.

exploring and expanding humankind’s
understanding of planet earth requires
state-of-the-art research equipment.
WhO WILL USe this science facility? And for what?
In the ship’s microscopy, paleontology, downhole logging,
core description, and petrophysics laboratories, scientists
will work to better understand earth’s climate conditions
and sea level in the distant past.
In the ship’s chemistry, paleomagnetism, thin section
and X-ray laboratories, petrologists, volcanologists
and geophysicists will analyze material and data during
expeditions focused on improving our understanding
of plate tectonics, volcano formation, gas hydrates,
and earthquake mechanisms.

DriLLinG
Dynamic positioning system, derrick and drill string. A highly trained crew and new specialized engineering equipment make it possible to target and core the seafloor.
91/2 meter sections of ocean sediment or rock are transferred from the drilling area to the laboratories for analysis by scientists and technicians.
cOre receiVinG anD PrOcessinG
Few research ships have a 22-foot hole in the center. The drill string drops through to the seafloor, and cores and downhole logging data return up through it en route to laboratories.
MOOnPOOL
WheTher cLUeS AbOUT our planet come from downhole
instruments the JOIDES Resolution sends deep below the
seafloor, or from rock and sediment samples the ship brings
to the surface, carrying out an expedition and extracting
research results requires specialized equipment and specially
trained staff on the vessel.
continuing work often extends for years while post-expedi-
tion research is carried out at shore institutions throughout
the world and results are published in international peer-
reviewed scientific publications.

DOWnHOLe LOGGinG
After cores have been extracted, the borehole itself becomes a laboratory. Scientists lower instruments or install long-term observatories to study the surrounding environment.
Cores are sliced lengthwise, analyzed and sampled, and one half is stored in Integrated Ocean Drilling Program repositories for future research.

Nearly 7,500 square feet of science space immediately spring to life as scientists conduct analyses, for example examining fossils in the freshly recovered cores to date the material.

DrILLIng Off The cOAST of Antarctica in an ocean basin known
as the Palmer Deep has given scientists a glimpse of the pace
of rapid climate and oceanographic change in the Southern
Ocean. rapid warming in the Antarctic Peninsula region today
has resulted in collapse of ice shelves and changes in the region’s
ecosystem. Sediments at the bottom of the Palmer Deep help
inform and ground-truth models predicting future conditions
because these sediments record 13 thousand years of history of
the region’s fluctuations from colder to warmer climates.
fluctuations are evident in the core in the olive green colored
diatom ooze layers, which early in the record alternate with
gray-colored diatom sandy mud, indicating a relativewly cooler
period when annual ocean productivity blooms alternate with
glacial meltwater, silt and sand pulses. Deeper in the record, the
alternating annual layers give way to sediments with more
glacial debris, likely released by meltwater and icebergs during
a warming trend. Thousands of cores like this one have their
own story to tell.

Future Past
In ITS PAST ServIce to the Integrated Ocean Drilling
Program, and the Ocean Drilling Program before it,
the JOIDES Resolution has operated from north of the
Arctic circle to south of the Antarctic circle and from
the depths of the Mariana Trench to the shallow coastal
shelf off new Jersey.
In the next phase of IODP operations, the drillship
is scheduled to conduct expeditions from the equatorial
Pacific, north to the bering Sea, then south to the
canterbury basin off new Zealand and Wilkes Land
off Antarctica.
