PAOC Spotlight: Back to the forest Video

Micro-organisms have produced dramatic shifts in the composition of the Earth’s atmosphere and continue to be important drivers of ocean- and land-atmosphere exchanges of gases that have a strong influence on atmospheric composition and climate. An interesting example is the microbial influence on atmospheric molecular hydrogen (H2), which dominates the fate of this gas in the atmosphere. H2 is emitted to the atmosphere by about half natural and half anthropogenic, or human-induced, processes but it is predominantly removed from the atmosphere by microorganisms in the soil, which makes this process the most important, yet least understood, player in the atmospheric H2 budget.

In this video graduate student Laura Meredith shares her thesis work to build and deploy an instrument to the Harvard Forest Long Term Ecological Research site in central Massachusetts. Laura is in the Climate Physics and Chemistry Program. Her advisor is Ron Prinn.

Porcupine takes over Harvard Forest EMS shed

The porcupine was first spotted in the fall during a lunch break at the Harvard Forest Environmental Measurement Site instrument shed. It continued to reside beneath the shed as was clearly evident by the snow tracks (or more like a trough) leading to a nearby chewed on balsam fir. I set up a crittercam to record the action, and have compiled a “best of” video of our porcupine waltzing through the snow…

Laura goes to Harvard Forest – instrument deployment

Deployment day!

Two years after embarking on my thesis project to design and build a custom instrument that measures hydrogen fluxes, I deploy my creation to the Harvard Forest Long Term Ecological Research site in Petersham, Massachusetts. The instrument shed is tight, but with the help of colleagues at Harvard University, the move is successful. In this short documentary by co-student Ryan Abernathey we introduce the forest and the project, but the work has only just begun…
