Our lab works broadly on biogeochemistry and ecosystem science, applied to a wide variety of both theoretical and practical questions. We enjoy trying to understand some of nature's complexity, and we believe strongly in applying objective science to sustaining the biosphere and human society. Our research encompasses a wide range of spatial scales, from microbial to ecosystem, regional, and global. Our research includes a broad range of inter-connected topical areas, illustrated below. Note that much of our research and many of our papers fall into two or more of these categories. Click on a topic to further explore research in the Howarth-Marino lab.

NYT Article on climate impacts of oil and gas
The New York Times, February 19, 2020,
"Oil and Gas May be a Far Bigger Climate Threat than we Knew"
reports on a study published in Nature
(2-19-2020) by Hmiel et al., using 14C in ice cores to determine that preindustrial anthropogenic fossil fuel emissions of methane have been underestimated
by 25 to 40% (link to Nature article).
This study is consistent with our research findings that emissions from fossil sources are corresponding larger than many have been estimating:

New paper: Is shale gas a major driver of recent increase in global atmospheric methane?
In a new paper in Biogeosciences, we use data on stable carbon isotopes to calculate the importance of methane from shale gas production in global fossil fuel emissions. Click here for the press release from the European Geophysical Union, and click here to download the article.
