Clean Air – Cool Planet’s climate fellows begin their fourth week today and we’re all now happily immersed in our projects. My project, looking at how climate change is impacting Vibrio bacteria population ecology, got off to a roaring start when my scientific mentors, Dr. Steve Jones and Dr. Vaughn Cooper from the University of New Hampshire, handed me a hefty stack of scientific literature. I dove right in, wading through study after study on how rising water temperatures and changing salinity due to rainfall are making the bacteria more prevalent and diverse along coastlines globally. This is mainly an issue due to the risk of human infection from one of the many pathogenic strains of Vibrio (not all types of the bacteria will make us sick, though some, like Vibrio cholerae which causes cholera, definitely will).
And then it gets even more complicated! Temperature and salinity are not the only environmental factors at play in estuary and coastal ecosystems, and let’s not even get started on the vast number of avenues for human exposure (anything from consuming raw shellfish to wound exposure in contaminated water), or the genetic markers of Vibrio pathogenicity which we don’t fully understand. I’ve also been doing some of my own research, looking to NOAA, the CDC and the FDA for more data. Needless to say, I’ve had my hands full with trying to learn and understand all of this information.
Luckily I’ve had some field experiences too- I spent the afternoon of June 12th on a sample collection trip with Dr. Jones, CA-CP President Adam Markham, as well as Adam’s daughter Tess. We took water, sediment and oyster samples from two locations in the Great Bay Estuary of New Hampshire and Maine where Jones has been studying Vibrio for more than two decades. We all got a chance to “rake” the oysters and I learned how to tell if an oyster is alive or if it is a “sweet one” just filled with mud. Since I’m from New Mexico, this was a novel experience for me, and quite enjoyable.
Just last Friday I began the first drafting stages of the “white paper” that I’ll be writing as the next step of my project. I started by outlining my thoughts and ideas in order to receive feedback from Drs. Jones and Cooper as well as Adam. Given all the data I’ve found its going to be a sizeable piece but hopefully the end product will help people get a better understanding of the complex issues surrounding Vibrio and climate change. Aside from the paper itself I plan to compose a 2 to 4 page fact/graphics sheet to summarize the most important aspects of this research and express why people should care about a tiny little organism like Vibrio.
Onward!
