The JR is currently drilling in the Bering Sea, where an international team of scientists is drilling more than 600 meters (2,000 feet) into the sea floor to extract sediment cores that will provide the first comprehensive records of environmental and oceanographic conditions in the area over the past 5 million years. The scientists hope to reconstruct the history of this shallow sea, which acts as a fence between the North Pacific and the frigid waters of the Arctic Ocean. |

Also on board is Teacher at Sea Doug LaVigne, from Acworth, Georgia. Follow his blogs at joidesresolution.org.

How scientists use the research results of deep-sea drilling—
“Sea sediments reveal how much ice existed in the world and hint at past temperatures and weather patterns. Ice cores also provide a glimpse of past temperatures and preserve tiny bubbles of ancient atmosphere.
|

Coral, tree rings, and cave rocks record cycles of drought and rainfall. Each piece of this complex puzzle must be put together to give us a picture of Earth’s climate history. Scientists’ efforts to explain the paleoclimate evidence—not just the when and where of climate change, but the how and why—have produced some of the most significant theories of how the Earth’s climate system works.”
from Paleoclimatology by Holli Riebeek, Earth Observatory
Ocean drilling has:
- Confirmed the theories of plate tectonics and continental drift.
- Provided major portions of the picture of changes to the global environment over the past 100 million years. For example, in 2004, core samples recovered from the seafloor beneath the Arctic Ocean revealed that 55 million years ago the Arctic region had a subtropical climate. Scientists continue to analyze these findings to better understand how ecosystems will respond to future global warming.
- Altered our thinking about the formation of geologic hazards like earthquakes, volcanoes and tsunamis.
- Discovered methane, in the frozen form of hydrates, in sediments below the ocean, and confirmed that they exist worldwide.
- Discovered a vast and active biosphere of microbes living deep below the seafloor, far deeper than scientists ever predicted life could exist.

Fire Drills and Emergency Rations
Today started with an early (actually 10:30am our time) fire drill. Everyone reported to their assigned life boat stations with our emergency gear on. Hard hats, safety goggles and life vests are required every time. While we did that, the fire team (members of the crew specially trained to fight fires) met in the laundry area to run through a mock fire scenario.
