DATA

    The growth of our knowledge is the result of a process closely resembling what Darwin called 'natural selection'; that is, the natural selection of hypotheses: our knowledge consists, at every moment, of those hypotheses which have shown their (comparative) fitness by surviving so far in their struggle for existence, a competitive struggle which eliminates those hypotheses which are unfit.

UMBS

Our group is collecting hydrological data at the University of Michigan Biological Station (UMBS). The data on soil moisture and precipitation are available through the Ameriflux portal: US-UMB and US-UMd (FASET) sites.

Top panel: Overview map of the fluxtower areas that include two 50m x 50m fine-scale plots, and long radial transects lines used for periodic soil moisture measurements. “Ameriflux ” indicates the US-UMB tower; “FASET” indicates the location of new tower deployed in 2008, US-UMd. “AOS” (AmeriFlux, Oak-dominated site), “AAS” (AmeriFlux, Aspen-dominated Site), “FOS” (FASET, Oak-dominated site), “FAS” (FASET, Aspen-dominated site). Bottom panel: Zoomed-in 50m x 50m fine-scale plot and sub-canopy short eddy-flux tower (3 m) at in the Ameriflux  and FASET footprints.

The figures illustrate continuous soil moisture and soil temperature observations (April 2009 – February 2011) from the sensor arrays in the Ameriflux footprint.
