title: The National Eutrophication Survey: lake characteristics and historical nutrient concentrations

description: Historical ecological surveys are an important source of baseline information to provide context for contemporary research, yet many of these records are not preserved in a way to ensure their long-term usability. The National Eutrophication Survey database is currently only available as portable document files (PDF) scanned from printed records with no embedded character information. This limits its searchability and the ability of current and future scientists to systematically evaluate its contents. The data was collected by the United States Environmental Protection Agency between 1972 and 1975, as part of an effort to investigate eutrophication in freshwater lakes and reservoirs. Although several studies have hand-transcribed portions of the database in support of specific studies, there have been no systematic attempts to transcribe and preserve the database in its entirety. Here we use a combination of automated optical character recognition and manual quality assurance to make this data available for analysis. The performance of the optical character recognition procedure was highly variable depending on scan quality. For each of the four archival pdf files, we found an error rate of between 5.9 and 17%. The goal of our approach was to strike a balance efficiency and data quality by combining hand-entry of data with digital transcription technologies. The finished database contains information on the physical characteristics, hydrology, and water quality of about 800 lakes in the continental United States. This database could be combined with more recent data to generate meta analyses of water quality trends and spatial variation across the continental United States.

title: Meteorological Database, Argonne National Laboratory, Illinois, January 1, 1948 - September 30, 2016

description: This data release is the update of the U.S. Geological Survey - ScienceBase data release by Bera and Over (2016), with the processed data through September 30, 2016. The primary data for each year is downloaded from the Argonne National Laboratory (ANL) (http://gonzalo.er.anl.gov/ANLMET/numeric/) and is processed following the guidelines documented in Over and others (2010) and Bera (2014). Daily potential evapotranspiration (PET) in thousandths of an inch is computed from average daily air temperature in degrees Fahrenheit (F), average daily dewpoint temperature in degrees Fahrenheit (F), daily total wind movement in miles (mi), and daily total solar radiation in Langleys per day (Lg/d) and disaggregated to hourly PET in thousandths of an inch using the Fortran program LXPET (Murphy, 2005). Missing and apparently erroneous data values were replaced with adjusted values from nearby stations used as backup. As stated in Over and others (2010), temporal variations in the statistical properties of the data resulting from changes in measurement and data storage methodologies were adjusted to match the statistical properties resulting from the data collection procedures that have been in place since January 1, 1989. The adjustments were computed based on the regressions between the primary data series from ANL and the backup series using data obtained during common periods; the statistical properties of the regressions were used to assign estimated standard errors to values that were adjusted or filled from other series. Each hourly value is assigned a corresponding data-source flag that indicates the source of the value and its transformations. As described in Over and others (2010), each flag is of the form "xyz" that allows the user to determine its source and the methods used to process the data. During the period 01/09/2016 hour 21 to 01/10/2016 hour 24, both ANL and the primary backup station at St. Charles, Illinois had missing wind speed data. The O'Hare International Airport (ORD) is used as an alternate backup station and the new regression equation and the corresponding new data-source flag for wind speed data are established using daily total wind speed data from ORD for the period 10/01/2007 through 09/30/2016 following the guidelines described in Over and others (2010). The detail is given in the child page containing wind speed data and the associated data-source flag.

title: Semillas de Ricinus comunis recogidas en doce poblaciones en Túnez

description: Images of the seeds were obtained with a scanner ScanJet 5300 C (HP). A list attached includes exact locations where seeds were gathered. This dataset is under a Creative Commons Attribution-Non commercial 4.0 International License.
description: Castor bean (Ricinus communis L.) is the unique species of the genus Ricinus in the family Euphorbiaceae. Traditionally used in agriculture, the seeds are a source of lipid reserves, secondary metabolites and fuels in the pharmaceutic and oil industry. The first mention of Ricinus communis as a laxative can be traced back to 3500 year-old Egyptian papyrus scrolls. The seeds are poisonous containing 2.8–3% toxic substances such as ricin, a potent inhibitor of protein synthesis, and agglutinin-1. Seed morphology may give information useful in the phenotypic characterization and phylogenetic relationships between varieties and cultivars. The seeds are characterized by high variability essentially in colour, size, weight and shape. Colour varies from red, white, grey, faint chocolate to purple and high variation is exhibited by the surface area, hundred-seed weight showed a wide range of variation from 11.6 to 59.1 g. Accurate geometric description of seeds requires the comparison with geometric figures that resemble seed images. The approach has been developed in the model plant (Arabidopsis thaliana) as well as in the model legumes, Lotus japonicus and Medicago truncatula. In Capparis spinosa the comparison of seed images with the cardioid curve was helpful to describe differences between two subspecies. In R. communis, high phenotypical variability is observed in the seeds, that also represent the interesting part of plant, as oil source. In the analysis of seed shape, the model applied for the geometric description has been an ellipse.

title: Demersal fish assemblages on seamounts and other rugged features in the northeastern Caribbean

description: Recent investigations of demersal fish communities in deep (less than 50 m) rugged habitats have considerably increased our knowledge of the factors that influence the assemblage structure of fishes across mesophotic to deep-sea depths. Although habitat types influence deepwater fish distribution, whether different rugged seafloor features provide functionally equivalent habitat for fishes is poorly understood. In the northeastern Caribbean, numerous rugged seafloor features (e.g., seamounts, banks, canyons) punctuate insular margins, and thus create a remarkable setting in which to examine demersal fish communities across various seafloor features. Also in this region, several water masses are vertically layered in the water column, creating strong stratification layers corresponding to specific abiotic conditions. In this study, we examined differences among fish assemblages across seafloor features (e.g., seamount, canyon, bank/ridge) and water masses at depths ranging from 98 to 4060 m in the northeastern Caribbean. We conducted 26 remotely operated vehicle (ROV) dives across 18 sites, yielding 156 species; 42% of which had not been previously recorded from particular depths or localities in the region. While fewer species were observed at seamounts than at other habitats in the NE Caribbean, assemblage structure was similar among habitat features. Thus, similar to seamount studies in other regions, seamounts in the Anegada Passage do not harbor distinct communities from other rugged, topographic features. Species assemblages, however, differed among depths, with zonation generally corresponding to water mass boundaries in the region. High species turnover occurred at depths less than 1200 m, and is driven by changes in water mass characteristics including temperature (4.8-24.4 C) and dissolved oxygen (2.2-9.5 mg per l). Our study demonstrates the importance of water masses in shaping community structure of benthic fauna, while considerably adding to the knowledge of mesophotic and deep-sea fish biogeography.

title: Lexical Relations from the Wisdom of the Crowd 1.0

description: A set of 300 most frequent nouns has been extracted from the Russian National Corpus. Then, each method or resource, including RuThes, produced at most five hypernyms, if possible. In case it is not possible, missing answers treated as empty results. This resulted in 9 322 unique non-empty subsumption pairs that have been passed for crowdsourcing annotation on the Yandex.Toloka microtask platform. Each pair has been annotated by seven different annotators whose mother tongue is Russian and the age is at least 20 by February 1, 2017. The layout of the human intelligence task (HIT) design assumes the direct answer to a simple question: does the given pair of words represent a meaningful <em>is-a</em> relation? Since the crowd workers are not expert lexicographers and this question might be difficult for them, it has been rephrased as “Is it correct that a <em>kitten</em> is a kind of <em>mammal</em>?” (in Russian). The answers have been aggregated using the Yandex.Toloka proprietary answer aggregation mechanism. As the result, 3 940 out of 9 322 pairs have been annotated as positive while the rest 5 382 have been annotated as negative. Interestingly, the workers were more confident in negative answers rather than in the positive ones. These negative answers are extremely useful for both training and testing different relation extraction methods. To the best of our knowledge, this is the first dataset of this kind made for the Russian language using microtask-based crowdsourcing.

title: Estimating carbon fluxes using satellite data integrated into regression-tree models in the conterminous United States

description: Integrating spatially explicit biogeophysical and remotely sensed data into regression-tree models enables the spatial extrapolation of training data over large geographic spaces, enhancing a more complete understanding of broad-scale ecosystem processes. This data release presents maps of estimates of annual gross primary production (GPP) and annual ecosystem respiration (RE) that were derived from weekly summaries of gross photosynthesis (Pg) and ecosytem respiration (Re). To conduct this study we used carbon data from flux towers that are scattered strategically across the conterminous United States (CONUS). We also calculate and present a map of average annual net ecosystem production (NEP). We present and analyze carbon flux dynamics in the CONUS to better understand how drought affects GPP, RE, and NEP. Our study experienced correlation coefficients (r) greater than or equal to 0.94 between training and estimated data for both GPP and RE. We conclude that this modeling method effectively measures carbon dynamics through time and allows the exploration of impacts of meteorological anomalies and vegetation types on carbon dynamics.
