title: Salinity yield modeling spatial data for the Upper Colorado River Basin, USA

description: These data (vector and raster) were compiled for spatial modeling of salinity yield sources in the Upper Colorado River Basin (UCRB) and describe different scales of watersheds in the Upper Colorado River Basin (UCRB) for use in salinity yield modeling. Salinity yield refers to how much dissolved salts are picked up in surface waters that could be expected to be measured at the watershed outlet point annually. The vector polygons are small catchments developed originally for use in SPARROW modeling that break up the UCRB into 10,789 catchments linked together through a synthetic stream network. The catchments were used for a machine learning based salinity model and attributed with the new results in these vector GIS datasets. Although all of these feature classes include the same polygons, the attribute tables for each include differing outputs from new salinity models and a comparison with SPARROW model results from previous research. The new model presented in these datasets utilizes new predictive soil maps and a more flexible random forest function to improve on previous UCRB salinity spatial models. The raster data layers represent aspects of soils, topography, climate, and runoff characteristics that have hypothesized influences on salinity yields.

title: Revealed preference analysis with normal goods: Application to cost of living indices

description: We present a revealed preference methodology for nonparametric demand analysis under the assumption of normal goods. Our methodology is flexible in that it allows for imposing normality on any subset of goods. We show the usefulness of our methodology for empirical welfare analysis through cost of living indices. An illustration to US consumption data drawn from the Panel Study of Income Dynamics (PSID) demonstrates that mild normality assumptions can substantially strengthen the empirical analysis. It obtains considerably tighter bounds on cost of living indices, and a significantly more informative classification of better-off and worse-off individuals after the 2008 financial crisis.<br>

title: Inference of tumor cell-specific transcription factor binding from cell-free DNA enables tumor subtype prediction and early detection of cancer

description: Deregulation of transcription factors (TFs) is an important driver of tumorigenesis. We developed and validated a minimally invasive method for assessing TF activity based on cell-free DNA sequencing and nucleosome footprint analysis. We analyzed whole genome sequencing data for &gt;1,000 cell-free DNA samples from cancer patients and healthy controls using a newly developed bioinformatics pipeline that infers accessibility of TF binding sites from cell-free DNA fragmentation patterns. We observed patient-specific as well as tumor-specific patterns, including accurate prediction of tumor subtypes in prostate cancer, with important clinical implications for the management of patients. Furthermore, we show that cell-free DNA TF profiling is capable of early detection of colorectal carcinomas. Our approach for mapping tumor-specific transcription factor binding <em>in vivo</em> based on blood samples makes a key part of the noncoding genome amenable to clinical analysis This dataset comprises genome-wide midpoint coverages across the early stage colon cancer cohort and non-cancer controls. For every TF and every sample, coverage values relative to the transcription factor binding site are specified ni tab-separated values (one file per sample, one line per TF)

title: Methane emissions (Alaska, Canada, Sweden, Siberia) proportional to permafrost carbon thawed in Arctic lakes since the 1950s

description: Permafrost thaw exposes previously frozen soil organic matter to microbial decomposition. This process generates methane and carbon dioxide, and thereby fuels a positive feedback process that leads to further warming and thaw. Despite widespread permafrost degradation during the past ~40 years, the degree to which permafrost thaw may be contributing to a feedback between warming and thaw in recent decades is not well understood. Radiocarbon evidence of modern emissions of ancient permafrost carbon is also sparse. Here we combine radiocarbon dating of lake bubble trace-gas methane (113 measurements) and soil organic carbon (289 measurements) for lakes in Alaska, Canada, Sweden and Siberia with numerical modelling of thaw and remote sensing of thermokarst shore expansion. Methane emissions from thermokarst areas of lakes that have expanded over the past 60 years were directly proportional to the mass of soil carbon inputs to the lakes from the erosion of thawing permafrost. Radiocarbon dating indicates that methane age from lakes is nearly identical to the age of permafrost soil carbon thawing around them. Based on this evidence of landscape-scale permafrost carbon feedback, we estimate that 0.2 to 2.5 Pg permafrost carbon was released as methane and carbon dioxide in thermokarst expansion zones of pan-Arctic lakes during the past 60 years.

title: Ice core ethane and acetylene measurements, Greenland and Antarctica, 0-1900 CE

description: Ethane and acetylene are non-methane hydrocarbons released from combustion processes, with shared sources from fossil fuel use, biofuel and biomass burning. Ethane is also thought to have a source through natural geologic outgassing (Etiope and Ciccioli, 2009). Ethane and acetylene levels in the atmosphere can be used to quantify the variability in fossil fuel and biomass burning through time. In this project, paleo-atmospheric levels of ethane and acetylene were co-measured in the air bubbles of polar ice cores using a wet-extraction (melt) method (see Nicewonger et al., 2016 GRL (Geophysical Research Letters), Nicewonger et al., 2018 PNAS, or Nicewonger, 2019 PhD thesis). Ice core samples from Summit, Greenland (GISP2B, GISP2D), and West Antarctic Ice Sheet (WAIS) Divide, Antarctica (WDC05A, WDC06A) and South Pole, Antarctica (SPC14) were analyzed covering the last 2,000 years (~0 –1900 Common Era). The paleo-atmospheric ethane levels from this project allowed for the reconstruction of biomass burning ethane emissions over the last 1,000 years (see Nicewonger et al., 2018 PNAS publication). Please refer to the corresponding manuscript for more information on the “_Ethane.txt” data and how the gas ages were calculated (Nicewonger et al., 2018 PNAS SI Appendix). The ethane data have been since updated (Aug. 2019) with new analytical blank corrections, resulting in slightly different mixing ratios than what is reported in the Nicewonger et al., 2018 PNAS (Proceedings of the National Academy of Sciences) publication. Please use the updated dataset for future analysis ("site_EthaneAcetylene_2ky.txt") The acetylene levels measured may be impacted by solubility loss in the melt water during the wet-extraction method. The correction factor for this loss is about 1.15. Both solubility corrected and uncorrected data are available in the data sets. Missing or excluded data are denoted with -999.0.

title: Kuparuk River photo-bio apparent quantum yield, Alaska, 2011-2012

description: Data set is apparent quantum yields (AQY) of photo-stimulated or photo-inhibited microbial respiration of dissolved organic matter (DOM) in the Kuparuk River. AQYs were measured at 350 nm as described in Cory et al. 2014. Positive AQY values mean that photo-altered DOM stimulated microbial respiration relative to dark controls. Negative AQY values mean that photo-altered DOM inhibited microbial respiration relative to dark controls. AQYs are averages with standard error of the average from four experimental replicates.

title: Sediment chemical data, Lake Hazen, Nunavut, Canada, August 4th to 8th, 2016

description: This data on porewater chemical concentrations of NH4+, NO2-/NO3-, SO42-, TDP and Cl-, and microprobe data on O2, redox potential, and pH in the sediments of Lake Hazen in August 2016 was gathered for a metagenomic study on the structure and functional potential of the sediment microbial community. The title of the study is "High-Arctic lake sediments are enriched in novel Metagenome Assembled Genomes fit for low temperature and oligotrophy". Abstract of the study follows: The Arctic is currently warming at an unprecedented rate, which may affect environmental constraints on the freshwater microbial communities found there. Yet, our knowledge of the community structure and function of High Arctic freshwater microbes remains poor, even though they play key roles in nutrient cycling and other ecosystem services. Here, using high-throughput metagenomic sequencing and genome assembly, we show that sediment microbial communities in the High Arctic’s largest lake by volume, Lake Hazen, are highly diverse and contain novel organisms. These assembled genomes displayed a high prevalence of pathways involved in lipid chemistry, and a low prevalence of nutrient uptake pathways, which might represent adaptations to the specific, extremely oligotrophic conditions in Lake Hazen. A third of the reconstructed genomes were distantly related to known reference genomes, and analysis of marker genes indicated that these novel genomes play key roles in fixing atmospheric nitrogen and assimilating it into organic forms. Furthermore, we observed that the nitrogen and sulfur cycles are catalyzed by a diverse microbial community in these sediments. Increasing nutrient delivery from melting glaciers might lead to disappearance of oligotrophic niches in the sediment and alterations in the microbial community, which might have unforeseen consequences on water quality in northern regions.

title: The Cosmogrid Simulation: Statistical Properties of Small Dark Matter Halos (2048-531)

description: We present the results of the "Cosmogrid" cosmological N-body simulation suites based on the concordance LCDM model. The Cosmogrid simulation was performed in a 30 Mpc box with 2048³ particles. The mass of each particle is 1.28x10^5 Msun, which is sufficient to resolve ultra-faint dwarfs. We found that the halo mass function shows good agreement with the Sheth & Tormen fitting function down to ~10^7 Msun. We have analyzed the spherically averaged density profiles of the three most massive halos which are of galaxy group size and contain at least 170 million particles. The slopes of these density profiles become shallower than -1 at the inner most radius. We also find a clear correlation of halo concentration with mass. The mass dependence of the concentration parameter cannot be expressed by a single power law, however a simple model based on the Press-Schechter theory proposed by Navarro et al. gives reasonable agreement with this dependence. The spin parameter does not show a correlation with the halo mass. The probability distribution functions for both concentration and spin are well fitted by the log-normal distribution for halos with the masses larger than ~10^8 Msun. The subhalo abundance depends on the halo mass. Galaxy-sized halos have 50% more subhalos than ~10^11 Msun halos have. This is snapshot 531 of the 2048³ resolution collection.

title: Methanesulfonate in the south central Greenland 20D ice core, 1767-1984

description: The concentration of methanesulfonic acid (MSA) was determined in a shallow south central Greenland ice core (20D). This study provides a high-resolution record of the DMS-derived biogenic sulfur in Greenland precipitation over the past 200 years. The mean concentration of MSA is 3.30 ppb (σ = 2.38 ppb, n = 1134). The general trend of MSA is an increase from 3.01 to 4.10 ppb between 1767 and 1900, followed by a steady decrease to 2.34 ppb at the present time. This trend is in marked contrast to that of non-sea-salt sulfate which increases dramatically after 1900 due to the input of anthropogenic sulfur. The MSA fraction ((MSA / (MSA +nss sulfate)) * 100) ranges from a mean of 15% in preindustrial ice to less than 5% in recent ice. These MSA fractions suggest that approximately 15 to 40% of the sulfur in recent Greenland ice is of biological origin. It is suggested that there is a significant low- latitude component to the biogenic sulfur in the core and that variations in the MSA fraction reflect changes in the relative strengths of low- and high-latitude inputs. The data show no evidence for a strong dependence of dimethyl sulfide (DMS) emissions on sea surface temperature during the last century. There is also no indication that the yield of MSA from DMS oxidation has been altered by increased NO x levels over the North Atlantic during this period. Details of the methods, data, and interpretation are given in: Whung, P.Y., E.S. Saltzman, M.J. Spencer, N. Gundestrup, and P.A. Mayewski, 1994.

title: Ultra-High Resolution Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) measurements of Younger Dryas onset in the Greenland Ice Sheet Project 2 (GISP2) ice core, Greenland

description: This data set contains the results of Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) performed on an archive of the GISP2 ice core containing the Younger Dryas onset. There are two sets of files from two sections of core samples, one with measurements of Ca, Na, and Fe concentrations at the same depth, and three files with those same measurements from a different section of the core. The primary objective of the research was to obtain records of platinum, iridium, and osmium concentrations and osmium isotope ratios in the GISP2 Greenland ice core in order to investigate the hypothesis that there was a meteorite or comet impact at the onset of the Younger Dryas abrupt climate event 12,900 years ago. These analyses are combined with high-resolution measurements of climate proxies obtained on the same samples. Osmium isotopes have the potential not only to conclusively confirm or refute the presence of an extraterrestrial impact, but also to provide information about the size and type of the impactor, should one be confirmed. High-resolution analyses of the atmospheric circulation proxies sodium, calcium, and iron represent a leap in ice core analysis resolution from one sample per three years to over 100 samples per year. The research activities contribute towards an understanding of what happened at the Younger Dryas, which will be of broad interest to geologists, geochemists, climatologists, archeologists, astronomers, and the general public. Following recent reports of a large anomaly in platinum concentration in the GISP2 ice core, four investigators performed a series of collaborative analyses at Dartmouth College and the University of Maine on GISP2 ice core samples of Younger Dryas age to: (1) evaluate the platinum spike at the Younger Dryas onset for potential contamination and contributions from volcanic and terrestrial sources, (2) measure osmium concentration and isotope composition to evaluate whether an impact occurred at the Younger Dryas onset and assess the nature of any impactor, and (3) assess the environmental change across this critical climate transition by measuring iron, sodium and calcium at storm-scale resolution using a new laser ablation mass-spectrometry system.
