- Description:
- It is commonly thought that volcanic glass only records volatile loss during the eruptions in the Moon. However, our recent work shows that Na, K and Cu (moderately volatile elements) in lunar 74220 orange glass beads are enriched near the bead surfaces and depleted in the bead interiors, forming an overall “U-shaped” profile. The “U-shaped” profile means that rather than being “lost” into space, Na, K and Cu were “gained” into the volcanic glass during the eruption, which is contrary to the “volatile loss” story. Three different instruments (EMP, SIMS and LA-ICP-MS) were used to verify the discovery. We propose that such U-shaped Na, K and Cu profiles were formed by initial outgassing and subsequent in-gassing of Na, K and Cu when the beads were flying from the vent onto the surface through the cooling volcanic gas plume. Hence, in-gassing and the formation of surface coatings are two processes that are genetically linked during the pyroclastic eruption and evolution of the gas cloud. To quantify the processes that formed the U-shaped profiles, we developed a diffusion and surface-equilibrium model using available literature data on Na and Cu diffusivity in basaltic melts. The model reproduced U-shaped Na and Cu concentration profiles with outgassing at high temperature and subsequent in-gassing as beads cooled. By fitting the measured Na and Cu profiles, we found that the cooling time scales of individual orange glass beads range from 48 to 179 s. This is the first time that both outgassing and in-gassing were modeled and the cooling time scales of individual 74220 volcanic orange glass beads were estimated. The discovery of the U-shaped profiles of moderately volatile elements inside volcanic beads provides significant constraints on partial pressures of relevant volcanic gas species in the eruption plume.

- Description:
- In this work, we perform Global Sensitivity Analysis (GSA) for the background solar wind in order to quantify contributions from uncertainty of different model parameters to the variability of in-situ solar wind speed and density at 1au, both of which have a major impact on CME propagation and strength. Scripts written in the Julia language are used to build the PCE and calculate the sensitivity results. Data is available in csv, NetCDF and JLD files. A `Project.toml` file is included to activate and install all required dependencies (See README for details).

- Description:
- The data and scripts are meant to show how burster dynamics determine response to a single biphasic stimulus. The files include data which show trends in the propensity of termination for different burster types and the MATLAB scripts used to generate this data. The MATLAB scripts also allow the user to generate their own data sets for alternative bursting paths and stimulus parameter combinations. Furthermore, they allow the user to visually examine the effects of single stimuli in the voltage timeseries and in state space. How the user can access these features of the script is described in the file "ReadMe.pdf."

- Description:
- The NASA MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft, which is currently in orbit around Mars, has been taking daily (systematic) measurements of the densities and temperatures in the upper atmosphere of Mars between about 140 to 240 km above the surface. Wind measurement campaigns are also conducted once per month for 5-10 orbits. These densities, temperatures and winds change with time (e.g. season, local time) and location, and sometimes fluctuate quickly. Global dust storm events are also known to significantly impact these density, temperature and wind fields in the Mars thermosphere. Such global dust storm period measurements can be compared to simulations from a computer model of the Mars atmosphere called M-GITM (Mars Global Ionosphere-Thermosphere Model), developed at U. of Michigan. This is an ongoing detailed comparison between direct global dust storm period measurements in the upper atmosphere of Mars and simulated MGITM fields and is important because it can help to inform us what physical processes are acting on the upper atmosphere during such large dust events. Since the global circulation plays a role in the structure, variability, and evolution of the atmosphere, understanding the processes that drive the winds in the upper atmosphere of Mars also provides key context for understanding how the atmosphere behaves as a whole system. A basic version of the M-GITM code can be found on Github as follows: https:/github.com/dpawlows/MGITM [less] About 4 months of Neutral Gas and Ion Mass Spectrometer (NGIMS) measurements of densities and winds have been made by the MAVEN team during the summer of 2018 (Elrod et al., 2019; Roeten et al 2022). For this specialized archive (Elrod et al. 2023), one reference measurement interval during this 2018 global dust storm (30-31 August 2018) is selected for detailed study of helium distributions (Elrod et al. 2023). The Mars conditions for this last of nine intervals have been used to launch corresponding M-GITM code simulations, yielding 3-D neutral density, temperature and wind fields for comparison to these NGIMS measurements. This last interval is used to provide M-GITM datacubes to explicitly extract the helium density (plus corresponding temperatures and neutral winds) along the trajectory of each orbit path between 140 and 240 km . A general README file is also provided for this Deep Blue Data archive detailing the contents of each file, while also summarizing the inputs and outputs of the M-GITM code simulations for this study.

Supporting data: Domain-agnostic predictions of nanoscale interactions in proteins and nanoparticles
- Creator:
- Saldinger, Jacob, Raymond, Matt , Elvati, Paolo, and Violi, Angela
- Description:
- The accurate and rapid prediction of generic nanoscale interactions is a challenging problem with broad applications. Much of biology functions at the nanoscale, and our ability to manipulate materials and purposefully engage biological machinery requires knowledge of nano-bio interfaces. While several protein-protein interaction models are available, they leverage protein-specific information, limiting their abstraction to other structures. Here, we present NeCLAS, a general, and rapid machine learning pipeline that predicts the location of nanoscale interactions, providing human-intelligible predictions. Two key aspects distinguish NeCLAS: coarse-grained representations, and the use of environmental features to encode the chemical neighborhood. We showcase NeCLAS with challenges for protein-protein, protein-nanoparticle and nanoparticle-nanoparticle systems, demonstrating that NeCLAS replicates computationally- and experimentally-observed interactions. NeCLAS outperforms current nanoscale prediction models, and it shows cross-domain validity, qualifying as a tool for basic research, rapid prototyping, and design of nanostructures., Software: - To reproduce all-atom molecular dynamics (MD) NAMD is required (version 2.14 or later is suggested).

- Description:
- Large geomagnetic disturbances (GMDs, also denoted as MPEs - magnetic perturbation events) have sufficient amplitude to cause geomagnetically induced currents (GICs) that can damage technical infrastructure. In this study we present occurrence statistics for GMD / MPE events with derivatives ≥ 6 nT/s and ≥ 20 nT/s from five stations in the MACCS and AUTUMNX magnetometer arrays in Arctic Canada at magnetic latitudes ranging from 65° to 75°. Earlier studies using data from these arrays (Engebretson et al., 2019a,b, 2021a,b) covered only two years (2015 and 2017) and focused on latitude- and local time-dependent occurrence patterns and short-term dependencies on solar wind/IMF parameters and magnetospheric activity indices. This study presents all available data from these stations from 2011 through 2022 to analyze variations of GMD activity over a full solar cycle. Intense GMD activity did not closely follow the sunspot cycle, but instead was lowest during its rising phase and maximum (2011-2014), was highest during the early declining phase (2015-2017), and reached a subsequent minimum early in the following sunspot cycle (2020). GMDs with amplitude >20 nT/s followed the same yearly pattern but peaked even more strongly during 2015-2017. Most of these GMDs were associated with high-speed solar wind streams (Vsw > 600 km/s), but not with strongly negative values of the SYM/H index. The majority of these GMDs, irrespective of the Vsw value, were accompanied within 10 min (and most often less) by other events with amplitude ≥ 6 nT/s and showed a mostly poleward progression. These results show that large amplitude but spatially localized nighttime GMDs are primarily associated with high-speed stream geomagnetic drivers during the declining phase of the solar cycle. This indicates that large GIC hazard conditions can occur for a variety of solar wind drivers and geomagnetic conditions and not only for fast-coronal mass ejection driven storms.

F3UEL: Flaring & Fossil Fuels: Uncovering Emissions & Losses
User Collection- Creator:
- Kort, Eric and Plant, Genevieve
- Description:
- Fossil energy production, processing, flaring, and transmission all can harm climate and air quality by emitting greenhouse gases and air pollutants. Studies now show that onshore oil and gas production emit much more methane than what is inventoried, and that local air quality impacts can be significant, however, natural gas flaring and offshore systems have been largely overlooked. The F3UEL (Flaring & Fossil Fuels: Uncovering Emissions & Losses) project aims to address these gaps by improving our understanding of offshore emissions, characterizing how flares behave in the real world, identifying what portion of the offshore system is responsible for emissions, and determining how such systems can be monitored. Spanning three years (2020-2022), the project employed an aircraft platform to measure including both greenhouse gas and air quality measurements. To sample the largest regions of current and potential future offshore production and flaring, airborne measurements targeted the Gulf of Mexico, offshore California and Alaska, the Bakken Formation (North Dakota) and the Permian and Eagle Ford Basins (Texas). Data provided here includes the airborne measurements collected using Scientific Aviation’s Mooney aircraft platform, equipped with spectroscopic instrumentation to measure methane, carbon dioxide, water vapor, nitrous oxide, and nitrogen oxide, in addition to meteorological variables such as wind speed and direction. Data products from our analysis of these airborne measurements are also provided, including estimated flare destruction removal efficiency for the Bakken, Eagle Ford, and Permian basins. Each data file is in .csv format and is accompanied by a readme file with further information and descriptors of the variables included. All users should cite the papers and datasets provided in the readme files for each individual dataset. Website: https://graham.umich.edu/f3uel This project is funded by the Alfred P. Sloan Foundation with additional support from the Environmental Defense Fund, Scientific Aviation, and University of Michigan (College of Engineering, Climate and Space Sciences and Engineering; Graham Sustainability Institute).

- Description:
- Rapid eye movement sleep (REM) is believed to have a binary temporal structure with “phasic” and “tonic" microstates, characterized by motoric activity versus quiescence, respectively. However, we observed in mice that the frequency of theta activity (a marker of rodent REM) fluctuates in a non-binary fashion, with the extremes of that fluctuation correlating with phasic-type and tonic-type facial motricity. Thus, phasic and tonic REM may instead represent ends of a continuum. These cycles of brain physiology and facial movement occurred at 0.01-0.06 Hz, or infraslow frequencies, and affected cross-frequency coupling and neuronal activity in the neocortex, suggesting network functional impact. We then analyzed human data and observed that humans also demonstrate non-binary phasic/tonic microstates, with continuous 0.01-0.04 Hz respiratory rate cycles matching the incidence of eye movements. These fundamental properties of REM can yield new insights into our understanding of sleep health.

- Description:
- The data represents weekly output from three 60-year CAM6 model runs. The output includes state (.h0. files) and tendency (.h1. files) fields for three difference model configurations of increasing complexity. State fields include temperature, surface pressure, specific humidity, among others; while tendencies include temperature tendencies, specific humidity tendencies, as well as precipitation rates. Using the state variables at a given time step, machine learning techniques can be trained to predict the following tendency field, which can then be applied to the state variables to provide the state at the next physics time step of the model.

Resources for Training Machine Learning Algorithms Using CAM6 Simple Physics Packages
User Collection- Creator:
- Limon, Garrett
- Description:
- The collection contains the code and the data used to train machine learning algorithms to emulate simplified physical parameterizations within the Community Atmosphere Model (CAM6). CAM6 is the atmospheric general circulation model (GCM) within the Community Earth System Model (CESM) framework, developed by the National Center for Atmospheric Research (NCAR). GCMs are made up of a dynamical core, responsible for the geophysical fluid flow calculations, and physical parameterization schemes, which estimate various unresolved processes. Simple physics schemes were used to train both random forests and neural networks in the interest of exploring the feasibility of machine learning techniques being used in conjunction with the dynamical core for improved efficiency of future climate and weather models. The results of the research show that various physical forcing tendencies and precipitation rates can be effectively emulated by the machine learning models.

Vani Region Archaeological Survey
User Collection- Creator:
- Ratte, Christopher and Mokrisova, Jana
- Description:
- The data presented here were collected in the course of an archaeological survey of the region around Vani in the Republic of Georgia, carried out between 2009 and 2011, with follow-up visits in 2014 and 2017. The survey was sponsored by the University of Michigan, the Institute for the Study of the Ancient World at New York University, and the Otar Lordkipanidze Institute of Archaeological Research in Tbilisi. , The archaeological site of Vani lies in the territory of ancient Colchis, a triangular area bordered by the Black Sea to the west and by the greater and lesser Caucasus Mountains to the north and south – famous in Greek legend as the land of the Golden Fleece and the home of Medea. Vani itself is situated approximately 70 km inland, in the foothills of the lesser Caucasus. A regional culture recognizable on the evidence of distinctive traditions of pottery and metalworking and the appearance of a network of relatively large settlements had emerged in Colchis by the late second and early first millennia BC. , Vani is one of the most extensively studied archaeological sites in Colchis. Excavations have revealed a continuous occupation sequence extending from the 8th to the 1st centuries B.C. Especially notable are the rich and unusual graves of the Classical period (6th-4th centuries), the monumental stone architecture of the Hellenistic period (3rd to 1st centuries), especially fortifications enclosing an area of approximately 6 ha, and the extensive evidence for interaction with the Mediterranean and Near Eastern worlds, including not only commercial and luxury imports (Greek transport amphorae, fine bronze and silver utensils from both the Greek world and Persia), but also local production of bronze sculpture and one long Greek bronze inscription., In spite of the richness of the site, however, important questions about its purpose and function over time remain unresolved. How extensive was the ancient settlement? Was Vani an isolated stronghold, a regional population center, a sanctuary, or a combination of two or all three? How does it compare with other sites in Colchis? In addition to ongoing research at Vani itself, regional survey provides an obvious approach to some of these questions. In previous years, examination of a number of outlying sites had already yielded remains extending in date from the Early Bronze Age to the mediaeval period., and The purpose of the regional survey project begun in 2009 was to integrate existing knowledge about Vani and environs into the kind of technological and conceptual framework characteristic of contemporary American survey archaeology. Of particular importance was the use of Geographical Information Systems (GIS) as an organizational and analytical tool, and of geophysical prospection both in the immediate environs of Vani and at regional sites. Like all regional surveys, our project recorded evidence of all periods, from prehistory to the present day, but we were particularly interested in questions having to do with the increasing social complexity of Colchis in the mid- and later 1st millennium BC – when Greek explorers began to establish colonies on the Black Sea coast of Georgia, and the Persian empire pushed up against the mountains of the Caucasus. What was the nature of Colchian society in this period? How was it affected by interaction with the larger Greek, Persian, and Pontic worlds? And how can regional survey at Vani and throughout Colchis help us to address these questions?

- Description:
- In 2009, an American-Georgian team of four archaeologists, four archaeology students, and a geophysicist carried out a four-week season of “extensive” survey of known archaeological sites, together with geophysical prospection at selected locations. In a second four-week season in 2010, with the additions of a geologist and an archaeobotanist, we continued our program of documentation of known sites and of exploratory geophysical prospection, and we also carried out limited test excavations at a number of sites. We returned for a shorter (one- to two-week) study seasons in 2011 and 2014, focusing on museum and archival research in Vani, Kutaisi, and Tbilisi., The area covered by our survey extends 15 km both east and west of Vani, and as far as 10 km south of Vani, from the Phasis River plain at approximately 50 m above sea level to the lower slopes of the lesser Caucasus, at approximately 1000 m above sea level. The purpose of the program was to visit all the previously identified archaeological sites in the region, and to integrate existing knowledge into a database of sites and a Geographical Information System. Each entry into this database is recorded as a dataset in this deposit. Entries recorded in 2009 are prefaced with the letter “A,” those recorded in 2010 are prefaced with the letter “B.” A single entry added in 2011 received the preface, “C.” In carrying out the survey, we depended heavily on the unpublished dissertation by Sulkhan Kharabadze, “Vanis Qveq’nis” Arqeologiuri Ruk’a (dzv.ts. VIII – akh.ts. III ss.) – Archaeological Map of the Territory of Vani (8th Century BC – 3rd Century AD) (Ph.D. dissertation: Georgian Technical University 2008). A map showing the locations of all the sites recorded by the survey is attached to this dataset., Our procedure for each site visit was as follows: we drove to the nearest village and searched out a local guide who could take us to the place we wished to see. We drove as far as we could to each site, then got out and walked, using GPS-equipped field computers (Trimble Geo-XM) to make a continuous record of our path. We recorded the lay of the land and any artifacts we saw en route (pottery sherds, traces of burnt daub, lithics and stone objects, architectural features in situ). We designated as points of interest any significant archaeological remains (concentrations of pottery, in situ features, notable stray finds, etc.), and every place we could identify where earlier discoveries had been made or archaeological excavations carried out. For every point of interest, we recorded the latitude, longitude, and elevation; took a series of digital photographs; and made a grab bag collection of pottery and other finds if possible. Where appropriate, we took basic measurements of architectural features (e.g., of Mediaeval towers). We also kept records of local place names, the names of our local guides, and any miscellaneous information they gave us. , Certain sites were selected for further investigation. These included Saqanchia A001, where we carried our geophysical survey and limited excavation; Shuamta, Melashvilebisgora A033, where we also carried out geophysical survey and limited excavation; Kveda Bzvani A047, where we carried out controlled collection of surface finds; and Zeda Bzvani, Meskhebisgora, A053, where we also carried out controlled collection of surface finds., The datasets recorded in this deposit include basic descriptions of each site, citations to previous publications, and links to relevant maps, photographs, and drawings. Where they exist, maps for individual datasets are labeled according to the name and number of the site, e.g., DapnariA002Map.jpg. The labels for photographs taken during the field season record their numbers in the sequence of photographs taken that season, e.g., Vani09.0047.jpg. A complete list of all photographs recorded in this way is available for download. Photographs and drawings of artifacts from individual sites made after the season are labeled with the names of the sites followed by the numbers assigned to the objects, with photographs saved as jpeg files, and drawings saved as tiff files; thus KvedaBzvani11-14.jpg is a photograph of objects 11-14 from the site of KvedaBzvani, while KvedaBzvani11-14.tif is a set of drawings of the same objects. Finally, drawings of sites where excavations were carried out are labeled with the name of the site, the number of the trench (if applicable), and the type of drawing, so that Shuamta2010.1Plan is a plan of Trench 2010.1 at Shuamta., and In addition, the collections in this deposit group datasets together according to important characteristics such as period (Bronze Age, Iron Age, etc.) or type (settlement, fortification, burial, and so on).

- Description:
- Atmospheric aerosols are emitted from both natural and anthropogenic sources, and they play an important role in climate, impacting solar radiation and cloud formation. Compared to other types of aerosol particles, primary biological aerosol particles (PBAP, e.g., fungal spores, bacteria, pollen, virus, etc.) are relatively understudied. However, they are linked to adverse health effects and have the potential to influence ice nucleation at higher temperatures. Anemophilous (or wind-driven) pollen is one of the important PBAP, impacts cloud properties under some conditions, and triggers allergic diseases such as allergic rhinitis (also known as hay fever) and asthma. Because pollen emission is closely associated with environmental drivers, the climatic change could influence pollen emission and consequently the incidence of allergic disease. Using CMIP6 model data, our research projects continental-scale changes in pollen emissions at the end of the century, considering the effects of temperature, precipitation, CO2, and future vegetation distribution change. While prior studies have evaluated single types of pollen, we use a mechanistic model to comprehensively simulate total pollen across the United States from all sources. Similar to previous single-source pollen studies, our simulations suggest that pollen season duration will lengthen, and pollen emission will increase in the future, but in addition, we identify new synergies between different pollen types that can influence the maximum daily pollen. Our work highlights that the changes of overlap between pollen seasons of different vegetation taxa can magnify or mitigate the impacts of climate change, which addresses the importance to study all pollen emissions comprehensively. Given pollen is one of the most common triggers of seasonal allergies, our findings also provide information to evaluate global health conditions in the future. In this study, all of the pollen emission data are written in NetCDF files.

- Description:
- Accurate prediction of physical alterations in carbonate reservoirs under dissolution is critical for development of subsurface energy technologies. The impact of mineral dissolution on flow characteristics depends on the connectivity and tortuosity of the pore network. Persistent homology is a tool from algebraic topology that describes the size and connectivity of topological features. When applied to 3D X-ray computed tomography (XCT) imagery of rock cores, it provides a novel metric of pore network heterogeneity. Prior works have demonstrated the efficacy of persistent homology in predicting flow properties in numerical simulations of flow through porous media. Its ability to combine size, spatial distribution, and connectivity information make it a promising tool for understanding reactive transport in complex pore networks, yet limited work has been done to apply persistence analysis to experimental studies on natural rocks. In this study, three limestone cores were imaged by XCT before and after acid-driven dissolution flow through experiments. Each XCT scan was analyzed using persistent homology. In all three rocks, permeability increase was driven by the growth of large, connected pore bodies. The two most homogenous samples saw an increased effect nearer to the flow inlet, suggesting emerging preferential flow paths as the reaction front progresses. The most heterogeneous sample showed an increase in along-core homogeneity during reaction. Variability of persistence showed moderate positive correlation with pore body size increase. Persistence heterogeneity analysis could be used to anticipate where greatest pore size evolution may occur in a reservoir targeted for subsurface development, improving confidence in project viability.
