Hierarchical scaling of carbon fluxes from terrestrial-aquatic interfaces in the Arctic
For the past decade, observations of carbonyl sulfide (OCS or COS) have been investigated as a proxy for carbon uptake by plants. Chandler Morris, Charlotte Kwong and Emily Follansbee joined a recent visit to Harvard Forest. We are using OCS and ozone fluxes to learn about the uptake mechanisms of mercury.
Magnitude and pathway of gaseous atmospheric mercury deposition in forests
Our observations in New York City include measurements of carbon dioxide, methane and carbon monoxide from a tall building, ground-based mobile platforms and small aircraft. We also measure species that are co-emitted with methane from different sources, ethane and nitrous oxide, at the CUNY NGENS Observatory.
Our understanding of the atmospheric composition of the most remote regions of the world has been limited by a lack of observations - until now.
