Winter is Coming

/ Field work, Lab news /

I have been going to Coweeta every one or two weeks for the past two months to monitor sprinkling events on the soil model. Although I am measuring only one thing, water, being precise is actually very difficult. There are 5 high-resolution tipping buckets on the hillslope to measure samples of input and one large

Creating a research brand – advice from my Ph.D. advisor published today in Science

/ Mentoring, Science /

Published in the working life section of Science, Jeff provides some good advice for early career academics – it’s “critical to find one’s focus and voice and have it heard—quickly.”  He discusses how early career scientists need to develop brand identity and reinforce this brand as much as possible.  Defining the optimal degree of focus and

New review paper on tracers in northern catchments

/ Lab news, Review paper /

Abstract: We examine how tracer studies have enhanced our understanding of flow paths, residence times and sources of stream flow in northern catchments. We define northern catchments as non-glacial sites in the temperate conifer/boreal/permafrost zone, focussing our review mainly on sites in North America and Europe. Improved empirical and theoretical understanding of hydrological functioning has

Paper published on mapping of hydropedologic spatial patterns

/ Lab news, Research paper /

A paper from Cody Gillin’s master’s thesis was accepted last week.  The manuscript titled “Mapping of hydropedologic spatial patterns in a steep headwater catchment” will be published in a special issue on hydropedology in the Soil Science Society of America Journal.  This paper appears in the special issue with another paper on the same project,

New paper about how forests lose nitrogen through shallow groundwater flowpaths

/ Lab news, Research paper /

In a paper published in the Proceedings of the National Academy of Sciences, McGuire working with a team from the Hubbard Brook Ecosystem Study found clear evidence of nitrogen loss through denitrification in isolated shallow groundwater patches in a small watershed. The findings were somewhat of a surprise because denitrification has been so difficult to

News release – Ecology team improves understanding of valley-wide stream chemistry

/ Lab news, News, Popular news /

BLACKSBURG, Va., April 22, 2014 – A geostatistical approach for studying environmental conditions in stream networks and landscapes has been successfully applied at a valley-wide scale to assess headwater stream chemistry at high resolution, revealing unexpected patterns in natural chemical components. “Headwater streams make up the majority of stream and river length in watersheds, affecting regional

Network chemistry patterns in headwater streams – new paper published in PNAS

/ Lab news, Research paper /

In a new article published this week in Proceedings of the National Academy of Sciences, we show how high-resolution mapping and analysis of water chemistry throughout a headwater stream network reveals unexpected patterns in how flowing water interacts with the surrounding landscape at multiple spatial scales.  Here’s the abstract and a link to the paper:

Commentary on US-Japan Joint Seminar

/ Commentary, Meetings, News /

A short paper summarizing the US-Japan Joint Seminar that we held last March was accepted for publication in Hydrological Processes.  The paper describes the intent and outcomes of the workshop, which focused on linkages between hydrology and biogeochemistry in forested catchments with an emphasis on climatic and environmental change.  The seminar last March spawned several
