Biomass Inventories at Harvard Forest EMS Tower since 1993
In 1993, we installed 40 circular, 10 m radius biometric plots in the footprint of the EMS tower on Prospect Hill. We randomly placed the plots within 100 m increments along ten 500 m transects that extend from the tower in the northwest and southwest directions. In 2001, we removed three plots (G3,
Distinct Source Water Chemistry Shapes Contrasting Concentration Discharge Patterns, Water Resources Research: Dataset.
This data package contains discharge and water quality data and model results at Coal Creek Watershed in the central Rocky Mountains of Colorado, USA. Files include high-frequency stream chemistry data collected during the period of Dec 2015 to Jun 2018, and model results of water storage and flux.
Plant species distribution within the Upper Colorado River Basin estimated by using hyperspectral and LiDAR airborne data.
This package is part of the Watershed Function SFA project and contains a remote sensing dataset acquired at the East River, Colorado. The remote sensing dataset is composed of vegetation maps computed from hyperspectral and LiDAR airborne data acquired by the NEON team in June 2018. The maps show t
Site-level Foliar C, N, delta13C data from samples collected during field survey associated with NEON AOP survey, East River, CO 2018.
Carbon (C) and nitrogen (N) weight percent concentrations were obtained from the bulk foliar samples collected across East River, Washington Gulch, Slate River, and Coal Creek watersheds in Gunnison, Colorado during the summer of 2018. These samples were collected from sun-lit leaves of meadow, shru

Hadrosaur Locomotion and Herding Behavior: Evidence from Footprints in The Mesaverde Formation, Grand Mesa Coal Field, Colorado
Dinosaur footprint casts from a Mesaverde (Campanian) coal mine near Gunnison, Colorado resemble those of the notorious "mystery dinosaur, Xosaurus" which was probably a giant hadrosaur. Existing footprint descriptions, although obscure and hard to verify, are too important to overlook, particularit
