Project: Exploring the effect of carbon and DOM quality on SWI nitrogen cycling

Exploring changes in carbon reactivity and composition, and the effect on the fate of nitrate, at a stream sediment-water interface

This work was conducted to explore how dissolved organic carbon (DOC) derived from different organic matter sources degraded within the sediment water interface (SWI), and how its reactivity or 'lability' affected nitrogen cycling and denitrification products within the SWI. Field work consisted of push-pull experiments at Augusta Creek, in Hickory Corners, MI, and additional laboratory studies were conducted by Joe-Lee Cullin and undergraduate Rachel Geiger at Michigan State. This work was supported by a Kellogg Biological Station LTER Summer Research Fellowship and a GSA Summer Research Grant, as well as the NSF Research Experiences for Undergraduates Program.

Society for Freshwater Science Annual Meeting

I had a blast at my first professional society meeting: the Society for Freshwater Science annual meeting, in Raleigh NC! The society took a strong stance for improving the environment to foster a more inclusive and diverse membership, allowing us to work together to preserve freshwater diversity. The Michigan student membership made a big step up to help organize events for the meeting next year in Detroit, and to engage the student membership in the intervening year. I also got to pinch-hit a very successful talk, and present my first year's Masters research at the poster session. Meeting so many role models and hearing so much awesome science has me riding high into the summer field season!

Zarnetske Lab members present at MSU Fate of the Earth Conference

Zarnetske Lab members Joe and Tyler presented posters at the MSU Fate of the Earth Conference, put on by the Environmental Science and Policy Program. Tyler presents on research from the 2016 summer field season at Snake Pond on Cape Cod, MA. Next stop for this research is the Society for Freshwater Science annual meeting in June!

Team Microzones travels to UConn on CUASHI travel grant

Zarnetske Lab and Microzones members Tyler and Sinchan received funding from the Consortium of Universities for the Advancement of Hydrologic Science to travel to collaborators at the University of Connecticut and USGS Geophysics Branch. They met with Microzones team members Dr. Martin Briggs and Dr. Fred Day-Lewis and students to train on traditional Darcy columns instrumented with electrical-resistivity probes (developed by project member Dr. Kamini Singha) to quantify bulk sediment properties.

Project: Near-stream groundwater dynamics at Hubbard Brook forest

Variations in near-stream groundwater dynamics in a headwater catchment at the Hubbard Brook Experimental Forest, NH

As part of a multi-student exploration of the connections between soils, shallow groundwater, and headwater streams in Watershed 3 at the Hubbard Brook Experimental Forest, we focused on the near-stream zone and hope to draw attention to the importance of stream-groundwater exchange in headwater streams and emphasize the variability of this exchange in both space and time.

MSU joins USGS and Mines on Cape Cod

The Microzones Project has officially kicked off! Tyler Hampton and Dr. Jay Zarnetske are representing MSU in this collaborative effort to understand the role of less mobile porosities in nitrogen processing in lake and river sediments. They are joined by Dr. Kamini Singha from Colorado School of Mines and Dr. Martin Briggs from the USGS Geophysics Branch at UConn.
Not a bad place to do science!

Introduction

   
I am pursuing my PhD in Earth Sciences and Water at the University of Waterloo in Ontario. I am working with Dr. Nandita Basu, researching the use of parsimonious models to understand watershed processes influencing stream chemistry and drinking water treatability in steep forested catchments impacted by wildfires. I come from a process-based earth science background, with previous work in surface-groundwater interactions in steep and low-gradient catchments, and in nitrogen cycling at this interface. I'm passionate about the intersection between these natural processes and the possible implications for policy and management decisions. I'm a graduate of Michigan State University and the University of New Hampshire.
