A Week of Firsts for This Arctic Nation
We are closing in on a week of intense focus and excitement for GEOTRACES and for the United States around the Arctic. President Obama became the first sitting president to visit Alaska, the US Coast Guard Cutter Healy with US GEOTRACES scientists completed the first unaccompanied US surface vessel transit to the North Pole, and…

It’s as Clear as Mud
For the sampling GEOTRACES is doing in the Arctic there is a specific goal of collecting just the top few dozen centimeters of sediment and the water just above it. Although the plan was good, things don’t always go perfectly.

Q&A: Park Williams on Drought, Climate and ‘Cracking the Code’
“Future extremes are going to occur more and more frequently. In planning, we don’t need to plan for the 2 degree warming that we are aiming for as a globe, we need to plan for the 10 degree increase in a day, or the year when there’s no water. We need to plan for worst-case…

Tree Rings on Hawai’i Could Hold New Knowledge About El Niño
Annual tree rings are a rare find in the tropical islands of the eastern Pacific. The new discovery of trees with annual rings on a Hawaiian volcano could provide new climate data from a part of the world where much of the variability of the El Niño-Southern Oscillation originates.

Tracing the Arctic
The land surrounding the Arctic Ocean is like a set of cradling arms, holding the ocean and the sea ice in a circular grasp. Within that cradle is a unique mix of waters, including freshwater from melting glacial ice and large rivers, and a salty mix of relatively warm Atlantic water and the cooler Pacific…
