Summer kick-off at Hubbard Brook

We’ve had a busy couple of weeks at Hubbard Brook.  Last week was the beginning of the REU program.  We have two excellent students, Nathaniel Rasnake and Delaney Peterson, from Virginia Tech who are both working on our lateral weathering project.  This week was the LTER site mid-term review of the Hubbard Brook Ecosystem Study.  …

Winter is Coming

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 …

Sprinkling on the model

Kevin, Brian, and I went to Coweeta to improve the irrigation system. They installed a pressure pump to the water line, then we placed tipping bucket rain gauges at randomized locations, and then Brian turned on the water. Water pressure was high enough! We tuned each sprinkler head so that water reached just to the …

Filtration, Irrigation, and Preliminary Instrumentation

Kevin, Brian, and I installed a reverse osmosis filtration system, an irrigation line, an electrical line, and several data instruments/loggers. This included pounding a 7-foot copper grounding rod into the ground. The filtration system is used to change the chemistry of local tap water to resemble that of rainfall for our experiment. Sunny weather, with …

Hoop-House at Coweeta

Construction on the soil model at Coweeta Hydrologic Laboratory has begun! We will be using the model for a water and nutrient reaction and transport experiment to answer questions, such as: What is the dominant process (e.g., biogeochemical or hydrologic) for controlling export of nutrients from a hillslope? Under what conditions can we expect these controls …

1000th water sample

Last week on our Hydropedology Project, Scott collected the 1000th water sample from watershed 3 at Hubbard Brook. This is quite a milestone!

3 more weeks to apply for summer REU position in New Hampshire

Applications for the Hubbard Brook Research Experience for Undergraduates (REU) Program are due by February 6 – that’s just 3 weeks away!  We are seeking a student to work on a hillslope hydrology project looking at how water travels through soils on its way to streams in forested ecosystems.  See our post from Dec. 11th …

Summer 2013 REU at Hubbard Brook on Hillslope Hydrology project

Hillslope hydrology component of the Hubbard Brook REU: We are seeking applicants for an REU position at the Hubbard Brook Experimental Forest in New Hampshire.  The program is a multidisciplinary project where students participate in a research project and also engage in outreach projects designed to help develop skills in communicating ecosystem information to broad audiences. The program …

Drilling through glacial till at Hubbard Brook

Today we drilled 5.5 meters through glacial till and didn’t hit bedrock.  What a blast!  It was our first experience with our new Shaw Drill, and even though it rained, we drilled all day long.  We selected a location along a ground-penetrating radar (GPR) transect we surveyed last March.  The GPR survey suggested that we …

Forest Roads and Sediment Project at the Reynolds Homestead: Field Work Update, Summer 2012

We are nearly two-thirds of the way finished with rainfall simulation experiments to measure sediment delivery from forest road approaches to stream crossings at the Reynolds Homestead. We have been doing three rainfall simulation experiments at intensities ranging from 20 to 60 mm/hr at each of six road approaches with the following treatments: 1) fresh …
