McMurdo Dry Valleys Community Respiration Rates : Quantifying the Activity of the Electron Transport System (ETS)

An important part of the McMurdo Long Term Ecological Research (LTER) is monitoring of spatial and temporal patterns, and processes that control net primary production (carbon dynamics) in perennial ice-covered lakes. One of the primary losses of carbon fixed by phytoplankton is through respiration, directly by the phytoplankton themselves and secondarily through the metabolic contributions of heterotrophic organisms such as bacterioplankton and protozoa. The coupling of low metabolic activity and supersaturated gases in the water column prohibits a direct measurement of respiration. Therefore, we measure the respiratory electron transport system (ETS) activity which drives oxidative phosphorylation, and hence oxygen consumption in all aerobic organisms (Packard 1985). This data set addresses this core area of research and estimates a community-wide respiration rate at specific depths in McMurdo Dry Valley lakes (Hoare, Fryxell and Bonney).

Digitized Particulate Matter Size Distribution Profiles from Literature Sources for Improved Size Representation of PM Emissions in Atmospheric Chemical Transport Models

<p>Processing particulate matter (PM) emissions for use in a chemistry transport model (CTM) such as GEM-MACH (Global Environmental Multiscale Modelling Air-Quality and Chemistry) requires detailed information about particle size distribution and chemical speciation for different PM emissions source types.&nbsp; The current PM size distribution and speciation profile library used at Environment and Climate Change Canada (ECCC) for preparing model-ready emission files for GEM-MACH contains very detailed chemical speciation profiles for PM emissions from 91 source types but only has three generic PM size disaggregation profiles, one each for mobile, point, and area sources.&nbsp; These generic profiles are used to disaggregate bulk PM emissions to a 12-bin sectional size representation, where PM<sub>2.5</sub> emissions are split into size bins 1-8 and PM<sub>10‑2.5</sub> emissions are split into bins 9 and 10. &nbsp;Since there is wide variability in the particle size distribution depending on the source type, the inclusion of source-type-specific PM size disaggregation profiles should lead to better representation of PM particle size for emissions from different source types in the model.</p> <p>A presentation entitled &ldquo;Expansion of a Size Distribution Profile Library for Particulate Matter (PM) Emissions Processing from Three to 32 Source Categories&rdquo; was given recently at the Community Modeling and Analysis System (CMAS) conference in Chapel Hill, North Carolina in October 2019 (<a href="https://www.cmascenter.org/conference/2019/slides/1300_zhang_expansion_size_2019.pptx">https://www.cmascenter.org/conference//2019/slides/1300_zhang_expansion_size_2019.pptx</a>) . &nbsp;This presentation described work carried out at ECCC to improve the PM size disaggregation profile library used to generate model-ready emissions. &nbsp;In particular, the number of PM size disaggregation profiles in the library was increased from three generic profiles to 32 source-type-specific profiles. &nbsp;After the conference, four more profiles were added to the library for a total of 36 PM size disaggregation profiles. &nbsp;In order to carry out this study, over 100 PM size distribution profiles from various PM emissions sources were gathered from literature publications, analyzed, and transformed into size disaggregation profiles that correspond to the GEM-MACH 12-bin sectional configuration. The 36 PM size disaggregation profiles that were obtained were then combined with detailed PM chemical speciation data to compile a new PM size disaggregation and chemical speciation library for emissions processing using the SMOKE (Sparse Matrix Operator Kernel Emissions) emissions processing system.</p> <p>This Excel workbook provides the digitized particle size distribution data for PM emissions from 36 different source types that were used as input to calculate the PM size disaggregation profiles for the GEM-MACH 12-bin sectional configuration. &nbsp;The digitized particle size distribution profiles were obtained by digitizing images of size distribution plots obtained from the literature publications using graph digitizing software such as Engauge Digitizer (<a href="http://markummitchell.github.io/engauge-digitizer/">http://markummitchell.github.io/engauge-digitizer/</a>) and WebPlot Digitizer (<a href="https://directory.fsf.org/wiki/WebPlotDigitizer">https://directory.fsf.org/wiki/WebPlotDigitizer</a>). By manually defining the axes and selecting points along the curve by computer mouse, a comma-separated-values file was generated for each size distribution profile image. &nbsp;From there, a series of transformations were carried out as required, including particle diameter conversions from aerodynamic diameter to Stokes diameter, and conversion of number-weighted size distributions to volume-weighted size distributions, in order to obtain a harmonized set of profiles.&nbsp; This Excel workbook contains the raw digitized data for all literature size distributions included in the compilation of the new library, as well as the diameter and size distribution weighting conversions.&nbsp; There are 39 worksheets: the first is an introductory worksheet entitled &ldquo;Spreadsheet_Info&rdquo; while the next 36 worksheets are ordered alphabetically and correspond to each of the 36 emissions source types for which a PM size disaggregation profile was generated. The final two worksheets contain digitized particle penetration data for common PM control devices.</p> <p>These digitized profiles may be used and adapted for use with other emissions processing systems and other CTMs with a size-resolved representation for PM. &nbsp;More details are provided in the following publication:</p> <p>Elisa I.

Dataset for 'Rotational dependence of turbulent transport coefficients in global convective dynamo simulations of solar-like stars'

<p>For moderate and slow rotation, magnetic activity of solar-like stars&nbsp;is observed to strongly depend on rotation,&nbsp;while for rapid rotation, only a very weak or no dependency is&nbsp;detected.&nbsp;These observations do not yet have a solid explanation in terms of dynamo theory.&nbsp;To work towards such an explanation,&nbsp;we numerically&nbsp;investigated the rotational dependency of dynamo&nbsp;drivers in solar-like stars, that is, stars that have a convective envelope of similar thickness as in the Sun.&nbsp;We ran semi-global convection simulations of stars with rotation&nbsp;rates from 0 to 30 times the solar value, corresponding to Coriolis numbers, Co, of 0 to 110. We measured the turbulent transport coefficients describing the magnetic field evolution with&nbsp;the help of the &nbsp;test-field method,&nbsp;and compared with the dynamo effect arising from the differential rotation, self-consistently generated in the models.&nbsp;The trace of the&nbsp;<strong><span class="math-tex">\(\alpha\)</span></strong> tensor increases for moderate rotation rates with Co<sup>0.5</sup>&nbsp;and levels off for rapid rotation.&nbsp;This behavior is in agreement with&nbsp;the kinetic <span class="math-tex">\(\alpha\)</span>&nbsp;based on the kinetic helicity, if one&nbsp;takes into account the decrease of the convective scale&nbsp;with increasing rotation.&nbsp;The <strong><span class="math-tex">\(\alpha\)</span></strong>&nbsp;tensor&nbsp;becomes highly anisotropic for Co &gt;&nbsp;1,&nbsp;<span class="math-tex">\(\alpha_{rr}\)</span>&nbsp;dominates&nbsp;for moderate rotation (1&lt;Co&lt;10), and <span class="math-tex">\(\alpha_{\phi\phi}\)</span>&nbsp;for rapid rotation&nbsp;(Co &gt; 10). The effective meridional flow, taking into account the&nbsp;turbulent pumping effects, is markedly different from the actual meridional circulation profile. Hence, the turbulent pumping effect is&nbsp;dominating the &nbsp;meridional&nbsp;transport of the magnetic field.&nbsp;Taking all dynamo effects into account, we find three distinct regimes. For slow rotation, the&nbsp;<span class="math-tex">\(\alpha\)</span>&nbsp;and R&auml;dler effects are dominating in presence of anti-solar&nbsp;differential rotation.&nbsp;For moderate rotation,&nbsp;<span class="math-tex">\(\alpha\)</span>&nbsp;and <span class="math-tex">\(\Omega\)</span>&nbsp;effects are&nbsp;dominant, indicative of <span class="math-tex">\(\alpha\Omega\)</span>&nbsp; or <span class="math-tex">\(\alpha^2\Omega\)</span>&nbsp;dynamos in operation,&nbsp;producing equatorward-migrating dynamo waves with the qualitatively solar-like rotation profile. For rapid rotation, an&nbsp;<span class="math-tex">\(\alpha^2\)</span>&nbsp;mechanism, with an influence from the R&auml;dler&nbsp;effect, appears to be the most probable driver of the dynamo. Our study reveals the presence of a large variety of dynamo effects beyond the classical <span class="math-tex">\(\alpha\Omega\)</span>&nbsp;mechanism, which need to be investigated further to fully understand the dynamos of solar-like stars.&nbsp;The highly anisotropic <strong><span class="math-tex">\(\alpha\)</span></strong>&nbsp;tensor might be the primary&nbsp;reason for the change of axisymmetric to non-axisymmetric dynamo solutions in the moderate rotation regime.</p> <p>For the full article see&nbsp;<a href="https://arxiv.org/abs/1910.06776">https://arxiv.org/abs/1910.06776</a></p>

MARTREC Data from Visualizing Sea Level Rise Impacts in Transportation Planning

<p>This research focuses on a study area in Fort Lauderdale--a two-block stretch of Las Olas Blvd. between Southeast 9th Ave. and Southeast 11th Ave. where researchers expect mean high tides up to 36 inches higher in the year 2100. The project investigates a community planning process in which a combination of high- and low-tech visualization methods&mdash;a Geographic Information System (GIS) and a human artist&mdash;was used to increase public participation and draw out local knowledge which helps the decision-making process for the future. Mixed reality technologies such as Microsoft Hololens (augmented reality) and Samsung VR Gear (virtual reality) offer immersive educational and engagement experiences, which may convey information in a more meaningful way. Using a quasi-experimental methodology of before-and-after surveys, we compare the degree to which virtual reality technologies improve<br> (or impede) constituents&rsquo; absorption of information regarding sea-level rise risks to roadway infrastructure in their communities.</p>

<p>Navajo Technical University (NTU) in New Mexico, has made a partnership with the Tran-SET regional center at Louisiana State University, LSU. We have provided learning and training the Native American students in transportation-related Industries to some of STEM students at NTU through these partnerships opportunities.<br> The program was designed and supported by Native American students from high school to STEM undergraduate students. The program was implemented accordingly with four main components: (1). Selected eligible and interested<br> Native American student to paid summer internships to the field and facilities of transportations industries and participate in research summer at LSU. (2). Directed the students to the transportation-related workshops and conducting at research NTU and they provided with and prepared them with the necessary background in transportation fields. (3). Several students were selected to research during the academic semester related to the field particularly, analyzing the causes of workforce shortages in the transportation industry. (4). We are planning to create and offer transportation certificate programs at NTU to train and expose the Native American students in transportation fields in the future if we get additional funding. We also proposed projects and conducted significant outreach activities in some of the local high schools and colleges. If successful we are planning to develop online courses, which would be provided for free to the Native American universities across the nation in order to make this program more sustainable.<br> Also, we are expected and planning to support 15-20 undergraduate and high school students per year through this partnership program. Other activities undertaken by NTU were the collaboration with different research, education, and outreach projects related to transportations undertaken by the NTU faculty partners. Some of the NTU STEM and pre-engineering students participated in the summer research internship programs, educational, laboratory, site visits as well as exposing students to the most technically-advanced Material research laboratories in Region 6 as well as state-of-the-art facilities at LSU. Some NTU students worked with local industries and agencies to enhance workforce development in the region.</p>

Data from: Solute Production and Transport Processes in Chinese Monsoonal Rivers: Implications for Global Climate Change

<p>Concentration-discharge (C-Q) relationships provide new insights into solute production processes. Temporal sampling and analyses are needed to investigate the chemical weathering behaviors and reduce the estimation errors of fluxes. But few studies have been done in Asian monsoonal rivers, which play an important role in global carbon cycle. We analyzed the dissolved solutes of Three largest rivers in China. Datong and Qingxi in Changjiang River were selected to represent the midterm and outlet of the Changjiang River. Lijin was selected as the outlet of the Yellow River. We analyzed the major ions, which can represent the chemical weathering index. Our study may help deepen the understanding of chemical weathering and solutes fluxes.</p>

Development, Education, and Implementation of a Low-Cost Audio Sensor-based Autonomous Surveillance System for Smart and Connected Transportation Infrastructure Construction and Maintenance

<p>Each DOT has to govern and oversee an enormous number of transportation construction and maintenance projects. However, since a transportation construction project entails several miles of a job site including numerous work tasks and equipment operations, it has been increasingly challenging for each DOT to consistently monitor progress of all projects in each State as well as efficiently evaluate work performance. In particular, with limited human resources and time, DOTs in Region 6 States have managed large-scale transportation construction and maintenance projects by a human inspection and recovered direct and indirect damages of transportation infrastructure systems caused from the recent natural disasters. In this demanding situation, DOT practitioners and project managers have long recognized the importance of automated monitoring and surveillance of transportation construction and maintenance processes that helps consistently track work progress and take immediate remedial action. As one promising supplement for site monitoring and human inspection, this project proposes a new approach for low-cost audio sensor-based autonomous site and safety surveillance of transportation construction and maintenance, which allows for faster, more convenient, and more accurate work zone monitoring. The proposed innovation using the sound-based site and safety monitoring framework possesses several competitive advantages over traditional site management and existing vision-based work monitoring methods, which not only sounds can be easily recognized and instantly analyzed by diverse sound sensors. In addition, this sound-based monitoring approach supports an unlimited range of monitoring angles and illumination levels with lightweight data processing and comparatively quick analytics. To achieve these goals, this study developed a low-cost wearable audio-sensor for automated work zone monitoring and real-time activity log generation. This new intelligent site and safety surveillance system is expected to support real-time monitoring of construction progress, evaluation of task performance, and rapid identification of safety issues in transportation construction and maintenance projects.</p>
