Data Release for "Holocene thermokarst lake dynamics in northern Interior Alaska: the interplay of climate, fire, and subsurface hydrology"

Lesleigh Anderson
The current state of permafrost in Alaska and meaningful expectations for its future evolution are informed by long-term perspectives on previous permafrost degradation. Thermokarst processes in permafrost landscapes often lead to widespread lake formation and the spatial and temporal evolution of thermokarst lake landscapes reflects the combined effects of climate, ground conditions, vegetation, and fire. This study provides detailed analyses of thermokarst lake sediments of Holocene age from the southern loess uplands of the Yukon...

A Century of Landscape Disturbance and Urbanization of the San Francisco Bay Region affects the Present-day Genetic Diversity of the California Ridgwayâ s Rail (Rallus obsoletus obsoletus).

Dustin A. Wood
Fragmentation and loss of natural habitat have important consequences for wild populations. Reductions in population size, density and connectivity can disrupt the distribution of genetic diversity within species and negatively impact long-term viability and resilience to environmental change. Genetic assessments of population structure, diversity and gene flow can provide important insights into conservation for rare and at-risk species. The California Ridgwayâ s rail (Rallus obsoletus obsoletus) is a state and federally endangered saltmarsh obligate that...

Using relative topography and elevation uncertainty to delineate dune habitat on barrier islands

Nicholas M Enwright, Richard H Day & Michael J
Dunes with a high relative topography can often be easily distinguished in high-resolution lidar-based digital elevation models (DEMs). Thus, researchers have begun using relative topography metrics, such as the topographic position index (TPI; Weiss, 2001), to identify ridges and upper slopes for extracting dunes from lidar-based DEMs (Wernette et al., 2016; Halls et al. 2018). DEMs are often used for automated delineations of intertidal and supratidal habitats in coastal applications despite issues related to vertical...

Yale stocks and flows database (YSTAFDB) describing anthropogenic materials cycles, recycling, and criticality for 102 materials on spatial scales ranging from suburbs to global and timescales from the early 1800s to circa 2017

Rupert J. Myers, Barbara K. Reck, Jessica A. Hopple, Michael S. Baker, Nedal T. Nassar & Thomas E. Graedel
This data release presents the Yale stocks and flows database (YSTAFDB). Its data describe the use of 102 materials from the early 1800s to circa 2017 through anthropogenic cycles, their recycling and criticality properties, and on spatial scales ranging from suburbs to global. This data collection was previously scattered across multiple non-uniformly formatted files such as journal papers, reports, and unpublished spreadsheets. These data have been synthesized into YSTAFDB, which is presented as individual comma-separated...

Bathymetric Data at Highway Bridges crossing the Lower Gasconade River after the May 2017 Flood in Central Missouri

Richard J Huizinga
These data are high-resolution bathymetry (riverbed elevation) in ASCII format, generated from hydrographic surveys near six highway bridge structures over the Gasconade River in central Missouri. These sites were surveyed in June 2017 to help identify possible effects from extreme flooding on May 1-2, 2017. At the five downstream sites, hydrographic data were collected using a high-resolution multibeam echosounder mapping system (MBMS), which consists of a multibeam echosounder (MBES) and an inertial navigation system (INS)...

Stable carbon isotope and wood component concentration data for riparian cottonwood tree rings, Little Missouri River, North Dakota

Craig A. Stricker & Jonathan M. Friedman
This dataset includes stable carbon isotope values, lignin, cellulose, and hemicellulose concentrations (expressed as percent of ash-free dry mass) for riparian cottonwood (Populus deltoides) tree rings growing on the Little Missouri River floodplain, Theodore Roosevelt National Park, North Dakota. Drought stress induces stomatal closure and the carbon isotope ratio of annual tree rings tends to be negatively correlated with water availability, especially in dry environments. However, lignin and hemicellulose can obscure annual trends in carbon...
