Abstract

Individual ice cores were collected from Barrow Environmental Observatory in Barrow, Alaska, throughout 2013 and 2014. Cores were drilled along different transects to sample polygonal features (i.e. the trough, center and rim of high, transitional and low center polygons). Most cores were drilled around 1 meter in depth and a few deep cores were drilled around 3 meters in depth. Three-dimensional images of the frozen cores were constructed using a medical X-ray computed tomography (CT) scanner. TIFF files can be uploaded to ImageJ (an open-source imaging software) to examine soil structure and soil densities within each core.The Next-Generation Ecosystem Experiments: Arctic (NGEE Arctic), was a 15-year research effort (2012-2027) to reduce uncertainty in Earth System Models by developing a predictive understanding of carbon-rich Arctic ecosystems and feedbacks to climate. NGEE Arctic was supported by the Department of Energy's Office of Biological and Environmental Research.The NGEE Arctic project had two field research sites: 1) located within the Arctic polygonal tundra coastal region on the Barrow Environmental Observatory (BEO) and the North Slope near Utqiagvik (Barrow), Alaska and 2) multiple areas on the discontinuous permafrost region of the Seward Peninsula north of Nome, Alaska.Through observations, experiments, and synthesis with existing datasets, NGEEmore »« less

NGEE Arctic Webcam Photographs, Barrow Environmental Observatory, Utqiagvik (Barrow), Alaska, 2012 - 2015

Dataset Busey, Bob

The NGEE-Arctic Webcam (PTZ Camera) captures two views of seasonal transitions from its generally south-facing position on a tower located at the Barrow Environmental Observatory near Utqiagvik (Barrow), Alaska. Images are captured every 30 minutes and available as *.jpeg files. The camera is operated by the U.S. DOE sponsored Next Generation Ecosystem Experiments - Arctic (NGEE-Arctic) project and credit also to Larry Hinzman. The Next-Generation Ecosystem Experiments: Arctic (NGEE Arctic), was a research effort to reduce uncertainty in Earth System Models by developing a predictive understanding of carbon-rich Arctic ecosystems and feedbacks to climate.

NGEE Arctic Leaf Spectral Absorptance, Utqiagvik (Barrow), Alaska, 2015-2016

Dataset Serbin, Shawn

Leaf level reflectance on each sample leaf was measured using a portable, full range (i.e. 0.35 to 2.5 microns) Spectra Vista Corporation (SVC) HR-1024i spectroradiometer, together with a leaf clip assembly with an internal, calibrated light source (SVC, Poughkeepsie, NY, USA). Each measurement was referenced against a LabSphere Spectralon (R) standard (LabSphere, Inc., North Sutton, NH, USA) to calculate leaf reflectance from the ratio of target and standard calibrated radiance measurements for each leaf. For each leaf, we collected two to five measurements over the leaf adaxial surface to calculate an average, depending on the leaf size and morphology. Spectralmore »« less
Ground Penetrating Radar, Utqiagvik (Barrow), Alaska

Dataset Peterson, John

This is 500 MHz Ground Penetrating Radar collected sporadically along the AB Line from 2012 to 2014 and along L2 (Site 0) from 2011 to 2014. A smaller area along AB line has also been surveyed in 2013 and 2014. Some of the surveys have been performed in the summer and fall season to estimate thaw depth (thaw depth measured right before the start of the freezing season have been used as proxy for active layer thickness). Some of the surveys have been performed in late fall when a thin snow layer was covering the ground and thus provide informationmore »« less
Airborne Imagery Collections, Utqiagvik (Barrow), Alaska, 2013

Dataset Cherry, Jessica ; Crowder, Kerri

The data here are orthomosaics, digital surface models (DSMs), and individual frames captured during low altitude airborne flights in 2013 at the Barrow Environmental Observatory. The orthomosaics, thermal IR mosaics, and DSMs were generated from the individual frames using Structure from Motion techniques. Data were collected to characterize the optical and thermal properties of the landscape and how they differ between two points in time with different vegetative and hydrologic conditions. The orthomosaic tiles, thermal IR mosaics, and DSMs are geotiffs in NAD 83 UTM Zone 4 named by their lower-left coordinate. Metadata for the raw imagery are contained inmore »« less
