Capturing Tundra Soil Respiration Another way to estimate how much carbon dioxide is being respired in response to a warming tundra is to capture the gas emitted from the soil environment and analyze it for radioactive carbon or 14C. ##Refresher on Radioactive Carbon Dating 14C is an radioactive

Refresher on Light Energy Visible light energy emitted from the sun is absorbed by the chlorophyll in green plants to be used in photosynthesis. Alternatively, a plant's cell structure reflects the near-infrared part of the energy spectrum. Plants with more leaves both absorb and reflect more of

Berry Mania It is blueberry season here in interior Alaska, where berry picking takes over the psyche. The public radio station, KUAC in Fairbanks, played, " I Get My Thrills on Blueberry Hill" just as we began the berry count last week. Berry picking has always been an addiction of mine, so

The High One Unveiled Today, we began our work at the Gradient Site, up the road from CiPEHR. It was a beautiful sunny morning, and I was blessed to see Denali, shining out from under the perpetual cloud cover. Denali, which means the "High One" in the Athabaskan language, was just last year

Today marks the last day of science stations. We will likely finish here this evening and then make our way to a mooring site (more on that in another journal). When I look at the map of our travels, it looks like a big lasso. What seemed like a long journey ahead quickly met the halfway point, and

The Invite During my May training visit at the University of Rhode Island (URI), Dr. Bethany Jenkins invited me to participate in the Ocean Carbon & Biogeochemistry (OCB) meeting in Woods Hole, MA. Dr. Jenkins explained that the OCB meeting would introduce me to many scientists that currently
