Jenn Fair, PhD
Dr. Fair is an ecohydrologist with the Eastern Ecological Science Center at the S.O. Conte Research Laboratory in Turners Falls, MA.
Fair leads an interdisciplinary team of fish ecologists, biologists, and hydrologists working to better understand the ecological impacts of streamflow extremes. Our team builds data systems that allow cooperators to share data, explore data, and visualize model predictions. Check out the USGS Flow Photo Explorer and the larger family os USGS ecoSHEDS data system applications.

Evaluating streamwater dissolved organic carbon dynamics in context of variable flowpath contributions with a tracer-based mixing model Evaluating streamwater dissolved organic carbon dynamics in context of variable flowpath contributions with a tracer-based mixing model
This study focuses on characterizing the contributions of key terrestrial pathways that deliver dissolved organic carbon (DOC) to streams during hydrological events and on elucidating factors governing variation in water and DOC fluxes from these pathways. We made high-frequency measurements of discharge, specific conductance (SC), and fluorescent dissolved organic matter (FDOM) during...

Export of photolabile and photoprimable dissolved organic carbon from the Connecticut River Export of photolabile and photoprimable dissolved organic carbon from the Connecticut River
Dissolved organic carbon (DOC) impacts water quality, the carbon cycle, and the ecology of aquatic systems. Understanding what controls DOC is therefore critical for improving large-scale models and best management practices for aquatic ecosystems. The two main processes of DOC transformation and removal, photochemical and microbial DOC degradation, work in tandem to modify and...

Source switching maintains dissolved organic matter chemostasis across discharge levels in a large temperate river network Source switching maintains dissolved organic matter chemostasis across discharge levels in a large temperate river network
Dissolved organic matter (DOM) helps regulate aquatic ecosystem structure and function. In small streams, DOM concentrations are controlled by transport of terrestrial materials to waterways, and are thus highly variable. As rivers become larger, the River Continuum Concept hypothesizes that internal primary production is an increasingly important DOM source, but direct evidence is...

Enhancement of primary production during drought in a temperate watershed is greater in larger rivers than headwater streams Enhancement of primary production during drought in a temperate watershed is greater in larger rivers than headwater streams
Drought is common in rivers, yet how this disturbance regulates metabolic activity across network scales is largely unknown. Drought often lowers gross primary production (GPP) and ecosystem respiration (ER) in small headwaters but by contrast can enhance GPP and cause algal blooms in downstream estuaries. We estimated ecosystem metabolism across a nested network of 13 reaches from...
