title: State of Sustainability Practices among Minnesota Tourism Businesses, 2007-2013

description: The dataset was used in three major ways. First, using data collected in 2013, we documented the current attitude towards sustainability practices among tourism businesses in Minnesota, particularly how they perceive the benefits and difficulties of implementing these practices. We also documented the extent of implementation of six types of sustainability practices, including energy efficiency, waste minimization, environmental purchasing, air quality, water conservation, and landscaping/wildlife. Second, we assessed whether attitude towards sustainability practices and the extent of implementing various practices changed over time (i.e., across the three surveys). Lastly, we benchmarked current level of knowledge of invasive species among Minnesota tourism businesses using data from the 2013 survey. This is the first time that the survey includes questions that assess knowledge of invasive species, providing a benchmarking opportunity.



We want to release this dataset, because there is little research that documents the extent to which different types of sustainability practices are implemented among tourism businesses in the state of Minnesota. The tourism industry makes significant contributions to the state's economy, at the same time, relying on the many natural assets that the state has to continue attracting visitors. Therefore, it is important that the tourism industry contributes to, rather than deters, the progress of sustainability practices. We believe that releasing this dataset will help increase public awareness of and interest in the trend of implementing sustainability practices among tourism businesses in Minnesota.

title: Two Years of Transient Cold-Climate Building Foundation Hygrothermal Experimental Data

description: The data consist of two years of continuous transient experimental measurements on the hygrothermal performance of concrete masonry block walls in a full basement in a cold climate (US DOE climate zone 7).  The walls were insulated in compliance with the thermal requirements of the 2012 International Energy Conservation Code and in compliance with the durability performance requirements of the 2009 MN Building Code.  These data are useful for verifying the physical validity of cold-climate foundation insulation system building code requirements; understanding the physics of heat and moisture transport in foundation walls from an experimental perspective; and, validating the predictions of thermal and hygrothermal building foundation simulation programs.  The data are in the public domain  and can be released now since the peer-review process has been completed.
description: Files explaining the details of the database (sensor nomenclature, sensor locations, etc) as well as a copy of the peer-reviewed final report on the data are included in this submission.

title: Sedimentary Record of Antibiotic Accumulation in Minnesota Lakes

description: The widespread detection of antibiotics in the environment is concerning because antibiotics are designed to be effective at small doses. The objective of this work was to quantify the accumulation rates of antibiotics used by humans and animals, spanning several major antibiotic classes (sulfonamides, tetracyclines, fluoroquinolones, and macrolides), in Minnesota lake-sediment cores. Our goal was to determine temporal trends, the major anthropogenic source to these lacustrine systems, and the importance of natural production. A historical record of usage trends for ten human and/or animal-use antibiotics (four sulfonamides, three fluoroquinolones, one macrolide, trimethoprim, and lincomycin) was faithfully captured in the sediment cores. Nine other antibiotics were not detected. Ofloxacin, trimethoprim, sulfapyridine, and sulfamethazine were detected in all of the anthropogenically-impacted studied lakes. Maximum sediment fluxes reached 20.5 ng cm−2 yr−1 (concentration 66.1 ng/g) for ofloxacin, 1.2 ng cm−2 yr−1 (1.2 ng/g) for trimethoprim, 3.3 ng cm−2 yr−1 (11.3 ng/g) for sulfapyridine, and 1.0 ng cm−2 yr−1 (1.6 ng/g) for sulfamethazine, respectively. Natural production of lincomycin may have occurred in one lake at fluxes ranging from 0.4 to 1.8 ng cm−2 yr−1 (0.1 to 5.8 ng/g).Wastewater effluent appears to be the primary source of antibiotics in the studied lakes, with lesser inputs from agricultural activities.

title: Capillary thinning analysis

description: This collection of scripts is a package for analyzing extensional rheology data of liquid bridges. While this was created with Dripping-onto-Substrate datasets, this data analysis package may be useful for other liquid bridge thinning applications such as CaBER. Any pre-processing of images, such as binarizing, converting to png or cropping, can be completed with ImageJ.
description: The data analysis package is composed of three distinct scripts designed to be run in Matlab with png image files. ContactAngle.m measures the contact angle of a liquid bridge and the spreading distance on the substrate for a series of images during liquid bridge thinning. Startpoint_Symmetry finds the minimum radius for a series of liquid bridge thinning images, identifies the start and end point of thinning, and gives information about the overall symmetry of the trials. EC_binning identifies the fitting region, fits and reports relaxation time for elastocapillary thinning fluids. For all three scripts, an example dataset is provided to demonstrate script functionality.

title:  Hydrokinetic turbine array performance and geomorphic effects under different siting strategies and sediment transport conditions: topography, flow velocity and array performance measurements 

description: Hydrokinetic energy can be extracted efficiently from naturally occurring water flows. Although representing a continuous and ubiquitous source of kinetic energy, rivers in particular are delicate environments, sensitive to external disturbances. Asymmetric installation of in-stream hydrokinetic energy converters have proven to actively interact with sediment transport and bedforms characteristics, triggering non-local geomorphic effects that resemble river instabilities known as forced-bars. This data-set comprises a series of measurements of channel topography evolution, flow velocity around the turbines and array performance under different configurations.

title: Three Dimensional Models and Two Dimensional Cross Sections of Châtelperronian and Protoaurignacian Lithic Cores from the sites of Les Cottés and Roc de Combe

description: These data were generated as part of a study investigating the use of quantitative methods on three dimensional models of lithic artifacts. The majority of the data set is comprised of 3D scans of  Châtelperronian and Protoaurignacian cores from the site of Les Cottés (France), which were generated using photogrammetry. Although cores from the site of Roc de Combe were also scanned for the associated study, we are not able to make them available here due to rights restrictions. The second part of the data set includes two dimensional representations of cross sections, which were from the 3D artifact models. These were used in two analyses, which are described in the associated publication (PUBLICATION INFORMATION FORTHCOMING PENDING PEER REVIEW).

title: Particle image velocimetry data characterizing flow and turbulence fields at free-flow-porous media interface 

description: The data includes two-dimensional (2D) instantaneous velocity fields and time-averaged 2D flow properties. We obtained the velocity data in an experimental flume, which is composed of an open channel and underlying porous media, at the St. Anthony Falls Laboratory, University of Minnesota using Particle Image Velocimetry (PIV). The PIV is a non-intrusive laser optical measurement technique, which measures flow at the high spatiotemporal resolution by estimating cross-correlations between laser-illuminated subsequent images recorded by a high-speed camera. We used the PIV-measured 2D flow fields to validate the results of numerical flow simulations based on Large Eddy Simulation. The main objective of this study is to investigate pore-scale flow effects on solute transport across open channel- porous media interfaces. The released data would also be useful to researchers who need to validate flow simulation results.
description: The released data consist of two-dimensional (2D) instantaneous velocity fields measured by PIV and a time-averaged 2D velocity and Reynolds shear stress fields. The measurement section of about 0.043 m (horizontal) × 0.17 m (vertical), located downstream about 2 m from the inlet of the flume, is illuminated by a 532 nm continuous-wave laser with 2 watt of output power (LRS-0532, Laserglow Technologies). Total 6,000 images within the FOV filled with seeding particles of 20 μm in diameter are recorded at 20 frames/s using a CMOS camera (2050 × 640 pixels, 8 bits, Flare 2M360 MCL, IO Industries) through a lens (AF Micro-Nikkor 60mm f/2.8D, Nikon). The time delay between subsequent images is set to 0.002 s. We post-processed the recorded images using the open- source PIV software, PIVlab (Thielicke and Stamhuis, 2014), for generating the instantaneous 2D velocity fields at a sampling frequency of 10 Hz. The interrogation window size is 32 × 32 pixels with 50% overlap, generating 39 × 127 velocity vectors in the measurement section.

title: Two and Three Dimensional Representations of Thomas Bewick Woodblocks 

description: The Bell Museum at the University of Minnesota owns fouteen wood blocks that were engraved in the workshop of Thomas Bewick to illustrate his History of British Birds, 2 vols. (Newcastle, 1797, 1804), as well as a block for a tail piece printed in The Fables of Aesop (Newcastle, 1818). This data set includes representations of these blocks captured using four digitization methods. 3D models were produced using structured light scanning and photogrammetry. Next, we used reflectance transformation imaging (RTI) to create interactive visualizations of the blocks' surfaces under variable lighting conditions. Finally, a high resolution two-dimensional image was generated for each block using a GIGAmacro device.

title: Raw data for: Biphasic Control of Cell Expansion by Auxin Coordinates Etiolated Seedling Development

description: Seedling emergence is critical for food security. It requires rapid hypocotyl elongation and apical hook formation, both of which are mediated by regulated cell expansion. How these events are coordinated in etiolated seedlings is unclear. Here, we show that biphasic control of cell expansion by the phytohormone auxin underlies this process. Shortly after germination, high auxin levels restrain elongation. This provides a temporal window for apical hook formation, involving a gravity-induced auxin maximum on the eventual concave side of the hook, triggering PP2C.D1-controlled asymmetrical H+-ATPase activity, resulting in differential cell elongation. Subsequently, auxin concentrations decline acropetally and switch from restraining to promoting elongation, driving hypocotyl elongation. Our findings elucidate how differential auxin concentrations throughout the hypocotyl coordinate etiolated development, leading to successful soil emergence.

title: Restoration of the 1936 Statewide Forest Survey of Minnesota

description: Long-term forest plot datasets have proven invaluable for understanding the changing conditions and ecology across Minnesota’s 17.3 million acres of forestland. Data from past and present USDA Forest Service (USFS) Forest Inventory and Analysis (FIA) program efforts are of high
quality and are informed by thousands of field plot observations for each survey.  The aim of this study was to locate historic forest records for Minnesota, identify useful data, and develop methodologies for digitizing and restoring data to a usable format.
description: Over 300 stand and stock tables and summary of volume tables for Minnesota were restored from the first FIA Lake States forest survey conducted between 1930 and 1938. The level of detail of the data varied, but included area of forest cover types and stand size classes, and number of trees and volumes per acre by individual species.  The data was presented in an Access database with a series of tables and queries.  Definitions and further explanations about the restored historic data can be found in Staff Paper Series No. 241, Department of Forest Resources, University of Minnesota

title:  Hard fescue (Festuca brevipila) reference transcriptome generated by PabBio Isoform sequencing 

description: Hard fescue (Festuca brevipila Tracey, 2n=6x=42) is a cool-season turfgrass with a fine leaf texture that performs well under low-input management. Breeding and genetics studies of F. brevipila have been limited due to the complexity of its hexaploid genome. To advance our knowledge of F. brevipila genomics, we used PacBio isoform sequencing to develop a reference transcriptome of this taxon. Here, we report a reference transcriptome generated from root, crown, leaf, and seed head tissues. We obtained 59,510 full-length transcripts of which 38,595 were non-redundant full-length transcripts, with a N50 of 2,585 bp. The longest and shortest transcripts were 11,487 and 58 bp, respectively. By using the long-read transcriptome assembly to improve the reference de novo short reads assembly we investigated the phylogenetic relationship between selected taxa that were closely related to F. brevipila. Overall, the F. brevipila Pacbio reference transcriptome improved the completeness of the short reads assembly and provided the foundation for genomics studies of this important turfgrass species.

title: Accumulation of recalcitrant dissolved organic matter in aerobic aquatic systems

description: Dataset from a paper submitted to Limnology and Oceanography Letters titled 'Accumulation of recalcitrant dissolved organic matter in aerobic aquatic systems'. Data include both experimental and observational data from a set of lakes just west of Kangerlussuaq, SW Greenland (67° N, 51° W). Experimental data were from incubations of lake water from several lakes that differ in salinity with microbes to examine the degradation of dissolved organic matter (DOM). The loss of DOM was followed for nearly a year and the results were fit to an exponential decline model. The observational data come from some of the same lakes but includes others in the region. These data include measurements of dissolved organic carbon (DOC), carbon stable and unstable isotopes (13C, 14C), optical properties (absorbance, SUVA, spectral slope) and specific conductivity. Other data include catchment characteristics for lakes in the region (lake and catchment area, altitude, maximum depth). Other data include profiles of dissolved oxygen and temperature for several of the lakes and the 14C dates.
