In situ cosmogenic radiocarbon production and 2-D ice flow line modeling for an Antarctic blue ice area

Creator:: Buizert, Christo, Petrenko, Vasilii V., Kavanaugh, Jeffrey L., Cuffey, Kurt M., Lifton, Nathaniel A., Brook, Edward J., and Severinghaus, Jeffrey P.
Abstract:: Radiocarbon measurements at ice margin sites and blue ice areas can potentially be used for ice dating, ablation rate estimates and paleoclimatic reconstructions. Part of the measured signal comes from in situ cosmogenic ¹⁴C production in ice, and this component must be well understood before useful information can be extracted...

Regional and global forcing of glacier retreat during the last deglaciation

Creator:: Shakun, Jeremy D., Clark, Peter U., He, Feng, Lifton, Nathaniel A., Liu, Zhengyu, and Otto-Bliesner, Bette L.
Abstract:: The ongoing retreat of glaciers globally is one of the clearest manifestations of recent global warming associated with rising greenhouse gas concentrations. By comparison, the importance of greenhouse gases in driving glacier retreat during the most recent deglaciation, the last major interval of global warming, is unclear due to uncertainties...

cBathy: A robust algorithm for estimating nearshore bathymetry

Creator:: Holman, Rob, Plant, Nathaniel, and Holland, Todd
Abstract:: A three-part algorithm is described and tested to provide robust bathymetry maps based solely on long time series observations of surface wave motions. The first phase consists of frequency-dependent characterization of the wave field in which dominant frequencies are estimated by Fourier transform while corresponding wave numbers are derived from...

Financial Performance of a Mobile Pyrolysis System Used to Produce Biochar from Sawmill Residues

Creator:: Kim, Dongyeob, Anderson, Nathaniel McLean, and Chung, Woodam
Abstract:: Primary wood products manufacturers generate significant amounts of woody biomass residues that can be used as feedstocks for distributed-scale thermochemical conversion systems that produce valuable bioenergy and bioproducts. However, private investment in these technologies is driven primarily by financial performance, which is often unknown for new technologies with limited industrial...

A simple model for internannual sandbar behavior

Creator:: Plant, Nathaniel G., Holman, Robert A., Freilich, Michael H., and Birkemeier, W. A.
Abstract:: Time and length scales of beach variability have been quantified using 16 years of beach surveys sampled at the Army Corps of Engineers' Field Research Facility, located on the U.S. Atlantic coast. Between 50% and 90% of the bathymetric variability at this site was explained by alongshore-uniform response over the...

A dynamical attractor governs beach response to storms

Creator:: Plant, Nathaniel G., Holland, K. Todd, and Holman, Robert A.
Abstract:: Sandbars are ubiquitous, yet not well understood beach features that change their position and shape in response to changing wave conditions. We propose and test a simple empirical model consisting of two coupled linear differential equations that represents bar dynamics in terms of wave forcing and two other state variables:...

A behavior‐oriented dynamic model for sandbar migration and 2DH evolution

Creator:: Splinter, Kristen D., Holman, Robert A., and Plant, Nathaniel G.
Abstract:: A nonlinear model is developed to study the time‐dependent relationship between the alongshore variability of a sandbar, a(t), and alongshore‐averaged sandbar position, xc(t). Sediment transport equations are derived from energetics‐based formulations. A link between this continuous physical representation and a parametric form describing the migration of sandbars of constant shape...

Spatial and temporal quantification of forest residue volumes and delivered costs

Creator:: Wells, Lucas A., Chung, Woodam, Anderson, Nathaniel M., and Hogland, John S.
Abstract:: Growing demand for bioenergy, biofuels, and bioproducts has increased interests in the utilization of biomass residues from forest treatments as feedstock. In areas with limited history of industrial biomass utilization, uncertainties in the quantity, distribution, and cost of biomass production and logistics can hinder the development of new bio-based industries....

Role of morphologic feedback in surf zone sandbar response

Creator:: Plant, Nathaniel G., Freilich, Michael H., and Holman, Robert A.
Abstract:: Several aspects of feedback mechanisms associated with surf zone sandbar response have been characterized using bathymetric surveys, sampled approximately monthly over a 16-year period at the Army Corps of Engineers' Field Research Facility (North Carolina). The measured bathymetry was alongshore averaged and modeled by the superposition of two Gaussian-shaped sandbars...
