Cloud-Sourcing: Using an Online Labor Force to Detect Clouds and Cloud Shadows in Landsat Images
We recruit an online labor force through Amazon.com’s Mechanical Turk platform to identify clouds and cloud shadows in Landsat satellite images. We find that a large group of workers can be mobilized quickly and relatively ...
From concept to practice to policy: modeling coupled natural and human systems in lake catchments
(Ecological Society of America, 2018-05-03)
Recent debate over the scope of the U.S. Clean Water Act underscores the need to develop a robust body of scientific work that defines the connectivity between freshwater systems and people. Coupled natural and human systems ...
Growth promotion and colonization of switchgrass (Panicum virgatum) cv. Alamo by bacterial endophyte Burkholderia phytofirmans strain PsJN
Background Switchgrass is one of the most promising bioenergy crop candidates for the US. It gives relatively high biomass yield and can grow on marginal lands. However, its yields vary from year to year and from location ...
Revisiting the Hewlett and Hibbert (1963) Hillslope Drainage Experiment and Modeling Effects of Decadal Pedogenic Processes and Leaky Soil Boundary Conditions
(American Geophysical Union, 2019-10-22)
Subsurface flow dominates water movement from hillslopes to streams in most forested headwater catchments. Hewlett and Hibbert (1963, https://doi.org/10.1029/JZ068i004p01081) constructed an idealized hillslope model (0.91 ...
Stream Runoff and Nitrate Recovery Times After Forest Disturbance in the USA and Japan
(American Geophysical Union, 2018-09-01)
To understand mechanisms of long-term hydrological and biogeochemical recovery after forest disturbance, it is important to evaluate recovery times (i.e., time scales associated with the return to baseline or predisturbance ...
Searching for biogeochemical hot spots in three dimensions: Soil C and N cycling in hydropedologic settings in a northern hardwood forest
(American Geophysical Union, 2014-08-01)
Understanding and predicting the extent, location, and function of biogeochemical hot spots at the watershed scale is a frontier in environmental science. We applied a hydropedologic approach to identify (1) biogeochemical ...
Streamflow response to increasing precipitation extremes altered by forest management
(Amer Geophysical Union, 2016-04-28)
Increases in extreme precipitation events of floods and droughts are expected to occur worldwide. The increase in extreme events will result in changes in streamflow that are expected to affect water availability for human ...
Storage selection functions: A coherent framework for quantifying how catchments store and release water and solutes
(American Geophysical Union, 2015-06-01)
Time-Varying Storage-Water Age Relationships in a Catchment With a Mediterranean Climate
(American Geophysical Union, 2018-06-01)
Recent studies on the relationships between catchment storage and water ages using Travel Time Distributions (TTDs), Residence Time Distributions (RTDs), and StorAge Selection (SAS) functions have led to the hypothesis ...
