Compilation of photos from the lab: Marshes, atmospheric deposition, alternative energy, modeled loading, and more.

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.

Publication wins John H. Martin Award

The John H. Martin Award is presented by the Association for the Sciences of Limnology and Oceanography (ASLO) to a paper that led to fundamental shifts in research focus and interpretation of a large body of previous observations. The 1996 paper, titled "Regional Nitrogen Budgets and Riverine N & P Fluxes for the Drainages to the North Atlantic Ocean: Natural and Human Influences", published in the journal Biogeochemistry, estimated Net Anthropogenic Nitrogen Inputs to the Gulf of Mexico and was published in a special issue based on a Scope workshop in 1993: Nitrogen Cycling in the North Atlantic Ocean and Its Watersheds.

You can read more about the article and award on the ASLO website and can view the full citation and download the article at this link.
