Uncovering the Census of Black Holes in sub-Milky Way Mass Galaxies
Creators: name: Nguyen, Dieu
Publisher: name: Zenodo
Year: 2019

description: Supermassive black holes are fundamental components of galaxies, as demonstrated by the correlations between black hole mass and large-scale galaxy bulge properties. Our understanding of the underlying physics driving the empirical scaling relations is not well understood by the present sample of galaxies for which dynamical BH masses have been measured. In particular, black hole mass determinations have been preferentially made in massive galaxies, leaving a small subset of seven dwarfs. We will address this bias using ALMA interferometric technique to detect and weigh black holes in nearby low-mass galaxies those are suitable for CO(2-1) high-resolution observations and gas-dynamical modeling methods. We target galaxies with total stellar masses smaller than that of our Milky Way those are currently missing in the existing sample of black hole mass measurements. We aim to provide the missing census of local black holes in a wide range of galaxies with diverse evolutionary histories, then determine the occupation fraction of central black holes in low-mass galaxies, which has substantial implications for the formation and growth of all supermassive black holes. In the era of ALMA, we hope to achieve a breakthrough in our understanding the black hole seeds formations mechanisms and co-evolution of black holes and galaxies.

description: After decades of molecular phylogenetic studies, the deep phylogeny of gymnosperms has not been resolved, and the phylogenetic placement of Gnetales remains one of the most controversial issues in seed plant evolution. To resolve the deep phylogeny of seed plants and to address the sources of phylogenetic conflict, we conducted a phylotranscriptomic study with a sampling of all 13 families of gymnosperms and main lineages of angiosperms. Multiple datasets containing up to 1 296 042 sites across 1308 loci were analysed, using concatenation and coalescence approaches. Our study generated a consistent and well-resolved phylogeny of seed plants, which places Gnetales as sister to Pinaceae and thus supports the Gnepine hypothesis. Cycads plus Ginkgo is sister to the remaining gymnosperms. We also found that Gnetales and angiosperms have similar molecular evolutionary rates, which are much higher than those of other gymnosperms. This implies that Gnetales and angiosperms might have experienced similar selective pressures in evolutionary histories. Convergent molecular evolution or homoplasy is partially responsible for the phylogenetic conflicts in seed plants. Our study provides a robustly reconstructed backbone phylogeny important for future molecular and morphological studies of seed plants, in particular gymnosperms, in the light of evolution.
Observations of 20 YSOs in Large Magellanic Clouds; searching for Extra-Galactic Complex Organic Mol
Creators: name: Hamedani Golshan, Roya
Publisher: name: Zenodo
Year: 2019

description: To investigate whether Complex Organic Molecules (COMs) exist in metal-poor galaxies and if they correspond to hot cores, we have conducted a survey of 20 YSOs in the Large Magellanic Cloud (LMC) . COMs form on the ice mantels of dust grains. They release into the gas phase, if an embedded hot core warm up the dust temperature or via non-thermal process. To date the only confirmed extra-galactic hot cores with complex chemistry has been found in N113 star forming region in the LMC. We have observed 20 fields, selected carefully to be away from star forming activity, inquiring the dust temperature under which COMs could be released into gas phase and survive. Our observation shows that all 20 fields contain at least one compact continuum source likely tracing a dust dense core, and all of them showing methanol line emission. We will present the first results of this small survey project towards the LMC. We do not detect the presence of more complex species, however temperatures and column densities are derived from the methanol lines using XCLASS software tools.
Dual frequency parametric excitation of a nonlinear multi degree of freedom amplifier with a digitally modified topology

description: Mechanical or electromechanical amplifiers can exploit the high-Q and low noise features of mechanical resonance, in particular when parametric excitation is employed. Multi-frequency parametric excitation introduces tunability and is able to project weak input signals on a selected resonance. The present paper addresses multi degree of freedom mechanical amplifiers or resonators whose analysis and features require treatment of the spatial as well as temporal behavior. In some cases, virtual electronic coupling can alter the given topology of the resonator to better amplify specific inputs. An analytical development is followed by a numerical and experimental sensitivity and performance verifications, illustrating the advantages and disadvantages of such topologies.

description: We discuss the structure of correlators involving the spinor emission vertex in non critical $N=1$ superstring theory. The technique used in the computation is the zero mode integration to arrive at the integral representation, and later an analysis of the pole structure of the integrals which are thus obtained. Our analysis has been done primarily for the 5-point functions. The result confirms previous expectations and prepares ground for a comparison with computations using matrix models techniques.

Tracing the mass loss history of WX Psc with ALMA and KVN
Creators: name: Yun, Youngjoo
Publisher: name: Zenodo
Year: 2019

description: We present the combined results of ALMA and KVN (Korean VLBI Network) observations toward WX Psc (IRC+10011) which is a long-period variable OH/IR star. The SiO masers of v=1 and v=2, J=5-4, and the SiO thermal emission of v=0, J=5-4 were observed together with the H2O v2=1, 5(5,0)-6(4,3) and continuum emission at ALMA Band 6 in October 2017 (Cycle 5). This ALMA observation aims to study the development of asymmetric outward motions during the evolutionary phases from the asymptotic giant branch (AGB) stars to the planetary nebulae (PNe), which are closely related to the conspicuous phenomena of the mass loss at the late stage of AGBs. The strong SiO and H2O maser features are detected around the continuum emission peak, which imply the asymmetric morphology of the high density regions of the inner circumstellar envelope (CSE) swept by the stellar winds. The clumpy structures of the CSE of this source are also clearly shown by SiO v=0, J=5-4 thermal components, which are very similar to the detached shell found in many carbon-rich evolved stars. The size of this detached shell-like structure is about 100 mas that corresponds to the dust layer around this object. The detached shell-like structures are known to be developed either through the interaction of distinct wind phases or an episodic mass loss eruption associated with a thermal pulse, thus they give a crucial information related to the mass loss history of late AGB stars. While the spatial resolution 20 mas of this ALMA observation cannot clearly resolve the detailed characteristics of the inner part of the CSE, the KVN observations show in detail the spatial distributions of the v=1 J=1-0, J=2-1, J=3-2 SiO masers emitted from the inner regions of CSE. Therefore, the monitoring VLBI observations of KVN for this source help us to trace the mass loss history combining the ALMA results, which can connect the stellar evolution to the wind and mass loss. The bipolar outflow feature is also found from the KVN results of 22 GHz H2O maser and the direction of the outflow axis, NW-SE, seems to be strongly related to the void regions of the SiO v=0 thermal shell structure found in this ALMA observation. These results show the power of the cross-facility synergies between ALMA and KVN for the study of stellar evolution.

description: Structural, magnetic and magnetotransport properties of (Bi$_{1-x}$Eu$_x$)$_2$Se$_3$ thin films have been studied experimentally as a function of Eu content. The films were synthesized by MBE. It is demonstrated that Eu distribution is not uniform, it enter quint-layers forming inside them plain (pancake-like) areas containing Eu atoms, which sizes and concentration increase with the growth of Eu content. Positive magnetoresistance related to the weak antilocalization was observed up to 15K. The antilocalization was not followed by weak localization as theory predicts for nontrivial topological states. Surprisingly, the features of antilocalization were seen even at Eu content $x$ $=$ 0.21. With the increase of Eu content the transition to ferromagnetic state occurs at $x$ about 0.1 and with the Curie temperature $\approx$ 8K, that rises up to 64K for $x$ $=$ 0.21. At temperatures above 1-2 K, the dephasing length is proportional to $T^{-1/2}$ indicating the dominant contribution of inelastic $e-e$ scattering into electron phase breaking. However, at low temperatures the dephasing length saturates, that could be due to the scattering on magnetic ions.

description: This evaluation of mapping techniques was prepared as part of the Texas Applications System Verification and Transfer (ASVT) project, which is a joint effort of the Texas Natural Resources Information System (TNRIS) Task Force and the National Aeronautics and Space Administration (NASA). The goal of the ASVT project, as described by McCulloch and McKain (1978), is to develop a Texas Natural Resources Inventory and Monitoring System (TNRIMS). The TNRIMS is designed "to assist agencies of the State of Texas in carrying out their statutory responsibilities in the areas of natural resources and the environment" (Finley and Baumgardner, 1981b, p. 2). This study evaluates the use of one component of the TNRIMS, the Remote Sensing Information Subsystem (RSIS), in its developmental state between March and August 1981. The project study area is part of the Coastal Applications Test Site (CATS) (fig. 1), one of five test sites in Texas included in the ASVT project. All test sites were selected to sample the wide variety of land cover/land use categories in the state. The coastal test site was chosen for this evaluation of the RSIS according to (1) state agency needs for information on coastal wetlands, (2) availability of personnel with experience in mapping coastal areas, (3) access to supplementary land cover/land use data, and (4) diversity of land cover/land use types in the area.

Dust polarization measurements in nearby galaxies to investigate magnetic fields in cold gas
Creators: name: Paladino, Rosita
Publisher: name: Zenodo
Year: 2019

description: ALMA, with its unprecedented combination of resolution and sensitivity in polarization, provides a new tool to investigate the role of magnetic field in nearby galaxies. So far magnetic field structure in external galaxies has mostly been studied through synchrotron emission and its polarization. These observations though do not probe the magnetic field in the cold gas, which can be traced with dust polarization. Recent results in the Milky Way show that there is a poor correspondence between the polarization properties obtained from radio synchrotron and those obtained from dust polarization measurements. To better understand this issue and possibly put constraints on the models observations of external galaxies are the most useful tool, since they have no bias due to the location inside the galaxy. I will present our projects of ALMA observations of dust polarization in a small sample of nearby galaxies, showing the potential of such a study in the investigation of the role of magnetic fields in regulating star formation processes and influencing galaxy evolution.

description: We report on the development of MPI-AMRVAC version 2.0, which is an open-source framework for parallel, grid-adaptive simulations of hydrodynamic and magnetohydrodynamic (MHD) astrophysical applications. The framework now supports radial grid stretching in combination with adaptive mesh refinement (AMR). The advantages of this combined approach are demonstrated with one-dimensional, two-dimensional and three-dimensional examples of spherically symmetric Bondi accretion, steady planar Bondi-Hoyle-Lyttleton flows, and wind accretion in Supergiant X-ray binaries. Another improvement is support for the generic splitting of any background magnetic field. We present several tests relevant for solar physics applications to demonstrate the advantages of field splitting on accuracy and robustness in extremely low plasma $β$ environments: a static magnetic flux rope, a magnetic null-point, and magnetic reconnection in a current sheet with either uniform or anomalous resistivity. Our implementation for treating anisotropic thermal conduction in multi-dimensional MHD applications is also described, which generalizes the original slope limited symmetric scheme from 2D to 3D. We perform ring diffusion tests that demonstrate its accuracy and robustness, and show that it prevents the unphysical thermal flux present in traditional schemes. The improved parallel scaling of the code is demonstrated with 3D AMR simulations of solar coronal rain, which show satisfactory strong scaling up to 2000 cores. Other framework improvements are also reported: the modernization and reorganization into a library, the handling of automatic regression tests, the use of inline/online Doxygen documentation, and a new future-proof data format for input/output

description: This area report describes the environmental characteristics of the Dalhart and Palo Dura basins in the Texas Panhandle portion of the Permian basin. Both basins are rather sparsely populated, and the overall population is decreasing. The economic base is centered on agribusiness and manufacturing. Most of the potentially conflicting land uses in both basins (i.e., parks, historic sites) occupy small land areas, with the exception of a national grassland in the Dalhart and military air training routes in both basins. Ground transportation in the Dalhart basin is adequate, and it is well developed in the Palo Dura basin. In both basins, irrigation constitutes the principal water use, and groundwater is the principal source. However, the dominant aquifer, the Ogallala, is being depleted. Both basins consist primarily of grasslands, rangelands, and agricultural areas. No critical terrestrial or aquatic habitats have been identified in the basins, though several endangered, threatened, or rare terrestrial species occur in or near the basins. Aquatic resources in both basins are limited because of the intermittent availability of water and the high salt content of some water bodies. Playa lakes are common, though usually seasonal or rain-dependent. The climate of the area is semiarid, with low humidity, relatively high wind speeds, and highly variable precipitation. Restrictive dispersion conditions are infrequent. National ambient secondary air quality standards for particulates are being exceeded in the area, largely because of fugitive dust, although there are some particulate point sources.

Transient events in bright debris discs: Collisional avalanches revisited
Creators: name: Thebault, Philippe
name: Kral, Quentin
Publisher: name: arXiv
Year: 2017
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: A collisional avalanche is set off by the breakup of a large planetesimal, releasing small unbound grains that enter a debris disc located further away from the star, triggering there a collisional chain reaction that can potentially create detectable transient structures. We explore this mechanism, using for the first time a code coupling dynamical and collisional evolutions, and investigate if avalanches could explain the short-term luminosity variations observed in some extremely bright discs. We consider two set-ups: a cold disc case, with a dust release at 10au and an outer disc extending from 50 to 120au, and a warm disc case with the release at 1au and a 5-12au outer disc. We find that avalanches could leave detectable structures on resolved images, for both cold and warm disc cases, in discs with optical depth $τ$ of a few $10^{-3}$, provided that large dust masses ($\gtrsim$10$^{20}$-5$\times$10$^{22}$g) are initially released. The integrated photometric excess due to an avalanche is limited, less than 10% for these released dust masses, peaking in the mid-IR and becoming insignificant beyond $\sim$40-50$μ$m. Contrary to earlier studies, we do not obtain stronger avalanches when increasing $τ$ to higher values. Likewise, we do not observe a significant luminosity deficit, as compared to the pre-avalanche level, after the passage of the avalanche. These two results concur to make avalanches an unlikely explanation for the sharp luminosity drops observed in some extremely bright debris discs. The ideal configuration for observing an avalanche would be a two-belt structure, with an inner belt of fractional luminosity >10$^{-4}$ where breakups of massive planetesimals occur, and a more massive outer belt, with $τ$ of a few $10^{-3}$, into which the avalanche chain reaction develops and propagates.

Dynamical signs of a spiral-like structure in the MonR2 hub-filament system
Creators: name: Trevino-Morales, Sandra P.
Publisher: name: Zenodo
Year: 2019

description: The study of the filamentary structures in massive star-forming regions is undergoing a revolution, thanks in large part to the unprecedented high angular resolution and sensitivity that ALMA provides. We have used ALMA to conduct an observational study towards MonocerosR2 (hereafter MonR2) star-forming region with the main goal of building a picture of its global dynamical properties. MonR2 is one of the nearest and clearest examples of a hub- filament system. The central hub hosts a cluster of massive protostars associated with an expanding HII region, where a number of filaments are converging. We have estimated the total mass accretion rate along the filaments on the order of 10^(-3) Msun/yr. Inside the central hub, the filaments appear twisted forming a spiral-like structure converging towards the central region where the most massive stars form. The spiral-like structure presents signs of rotation and infall motions, posing the question of whether these structures are required in the formation of massive stars or are an outcome of the accretion process.

description: The continuity of sandstone reservoirs is controlled by various factors including structural trend, sand-body geometry, and the distribution of framework grains, matrix, and interstices within the sand body. Except for the limits imposed by faults, these factors are largely inherited from the depositional environment and modified during sandstone compaction and cementation. Regional and local continuity of sandstone reservoirs depends on a depositional and structural hierarchy of four levels: (1) genetically related sandstones commonly associated with a single depositional system, (2) areally extensive fault blocks, (3) individual sandstones within a fault block, and (4) isolated reservoirs within a fault-bounded sandstone. Compilation of published and unpublished data for Tertiary and late Quaternary Gulf Coast sandstones of fluvial, deltaic, barrier-strandplain, and submarine fan origins suggests that volumes of sand systems (first hierarchical level) range from 10^11 to 10^13 ft^3, whereas volumes of individual sand bodies range from 10^9 to 10^11 ft^3. The continuity and productive limits of the ancient sandstones are substantially reduced by faults and internal heterogeneity that further subdivide the sand body into individual compartments. For the Wilcox and Frio trends of Texas, fault blocks (second hierarchical level) vary greatly in size, most being between 0.3 and 52 mi^2 in area; however, the distribution is strongly skewed toward small areas. Volumes of individual reservoirs (fourth hierarchical level) determined from engineering production data are 50 percent less to 200 percent more than estimates obtained from geologic mapping. In general, mapped volumes underestimate actual volumes where faults are non-sealing and overestimate actual volumes where laterally continuous shale breaks cause reductions in porosity and permeability.
The COMplexity of Orion: an ALMA view
Creators: name: Pagani, Laurent
Publisher: name: Zenodo
Year: 2019

description: Orion KL is the closest (400 pc) of all the massive star forming regions and allows therefore detailed studies. Despite its closeness, its complexity still calls for interferometric observations in order to separate the different subregions emitting at different velocities, which are otherwise mixed in an inextricable combination of different species at similar apparent frequencies in single dish observations. Orion KL has another peculiarity : it has undergone an explosive event 550 years ago as revealed by H2 and CO maps, and also by the proper motion of three stellar objects, BN, I and x. While our ALMA observations were mostly aimed at detecting the rare isotopologue 16O18O to follow up on our Herschel detection of O2 towards this region (Goldsmith et al. 2011, Chen et al. 2014), we took the advantage of that deep search to observe 16 GHz of spectral band in the 1.3 mm window. We did not detect 16O18O but the quality of our data (a 5-fold improvement compared to the similar data taken during Science Verification 0) allowed us to identify a few species not detected yet in Orion, and study the kinematics of the region in detail. In particular, we report gGg' ethylene glycol and acetic acid detections in a peculiar place, and we explain the line position and shape of each subregion, both in relation with the 550 years-old explosion. We show that based on this kinematics, we can make a 3D description of the region. The data quality is high enough to also study each species channel-wise. This reveals gas expansions never seen before which are traceable back to the explosion center. These expansions are comparable to time-of-flight experiments in the laboratory and allow therefore to establish the order of evolution between species, from those that are destroyed soon after their sublimation from the ices to those which survive until they get too diluted to be observed. This brings interesting clues to the chemistry of hot regions, and in particular of complex organic molecules (COMs). For example, we think that a route exists to produce ethyl cyanide in the gas phase (as also advocated by Suzuki et al. 2018).

The REFLEX cluster sample is flux limited to 3x10^{-12} erg s^{-1} cm^{-2} in the ROSAT energy band (0.1-2.4 keV) and spans 3 decades in X-ray luminosity (10^{42} - 10^{45} h^{-2} erg s^{-1}), containing galaxy groups and rich clusters out to a redshift z~0.3. Covering a contiguous area of 4.24 sr REFLEX is the largest X-ray cluster sample to date for which spatial clustering has been analysed. Correlation studies using clusters selected on the basis of their X-ray emission are particularly interesting as they are largely free from the projection biases inherent to optical studies. For the entire flux-limited sample we find that the correlation length (the scale at which the correlation amplitude passes through unity) r_0~20 h^{-1}Mpc. For example, if a power-law fit is made to xi(r) over the range 4-40 h^{-1} Mpc then r_0=18.8+-0.9. An indication of the robustness of this result comes from the high degree of isotropy seen in the clustering pattern on scales close to the correlation length. On larger scales xi(r) deviates from a power-law, crossing zero at ~45h^{-1} Mpc. From an examination of 5 volume-limited cluster sub-samples we find no significant trend of r_0 with limiting X-ray luminosity. A comparison with recent model predictions for the clustering properties of X-ray flux-limited samples, indicates that Cold Dark Matter models with the matter density Omega_m=1 fail to produce sufficient clustering to account for the data, while Omega_m~0.3 models provide an excellent fit.

description: Apnea, bradycardia and desaturation (ABD) events often precede life-threatening events including sepsis in newborn babies. Here, we explore machine learning for detection of ABD events as a binary classification problem. We investigate the use of a large neural network to achieve a good detection performance. To be user friendly, the chosen neural network does not require a high level of parameter tuning. Furthermore, a limited amount of training data is available and the training dataset is unbalanced. Comparing with two widely used state-of-the-art machine learning algorithms, the large neural network is found to be efficient. Even with a limited and unbalanced training data, the large neural network provides a detection performance level that is feasible to use in clinical care.

description: The upper Triassic Dockum Group accumulated in relict Paleozoic basins defined in Texas by the Amarillo Uplift on the north and the Glass Mountains on the south. These basins were reactivated during the late Paleozoic or early Mesozoic by tectonic activity that was probably related to the opening of the Gulf of Mexico. As basins subsided and some relict positive elements were uplifted, sedimentation rates increased. More than 2,000 ft (610 m) of terrigenous elastics, derived chiefly from Paleozoic sedimentary rocks, accumulated within the basin. Source areas were in Texas, Oklahoma, and New Mexico; sediment transport was from the south, east, north, and west. The Dockum Group accumulated in a variety of depositional environments including: (1) braided and meandering streams; (2) alluvial fans and fan deltas; (3) distributary-type lacustrine deltas (high-constructive elongate deltas); (4) ephemeral and relatively long-lived lakes; and (5) mud flats. Alternation of wet and dry climate caused cyclic sedimentation in the Dockum. The main control on climate was most likely tectonism. During wet periods, lake level was relatively stable. Meandering streams supplied sediment to high-constructive elongate deltas in the central basin area of Texas and New Mexico, whereas braided streams and fan deltas were dominant depositional elements along southern and northern basin margins. Lake area and depth decreased when dry conditions prevailed. Under these conditions, base level was lowered, valleys were cut into older Dockum deposits, and small fan deltas were built into ephemeral lakes; evaporites, calcretes, silcretes, and soils developed upon emergent surfaces ranging from floors of ephemeral lakes to delta platforms.
Cinnamons: A Computation Model Underlying Control Network Programming

description: We give the easily recognizable name "cinnamon" and "cinnamon programming" to a new computation model intended to form a theoretical foundation for Control Network Programming (CNP). CNP has established itself as a programming paradigm combining declarative and imperative features, built-in search engine, powerful tools for search control that allow easy, intuitive, visual development of heuristic, nondeterministic, and randomized solutions. We define rigorously the syntax and semantics of the new model of computation, at the same time trying to keep clear the intuition behind and to include enough examples. The purposely simplified theoretical model is then compared to both WHILE-programs (thus demonstrating its Turing-completeness), and the "real" CNP. Finally, future research possibilities are mentioned that would eventually extend the cinnamon programming into the directions of nondeterminism, randomness, and fuzziness.

description: During FY81, studies of the East Texas salt domes continued to evaluate those problems that must be solved before approving a salt dome for burial of nuclear waste. Questions addressed were: (1) Will the integrity of the hydrologic system prevent a release and migration of radioactive isotopes to the biosphere? (2) Will either tectonic or structural instability preclude a secure repository? The U.S. Geological Survey (in Bredehoeft and others, 1978, p. 3), the U.S. Department of Energy (DOE) (1980, in NE-0007, table 11-9), and the U.S. Office of Nuclear Waste Isolation (ONWI) (1980, in ONWI 33(2), p. 9-17) recognize the same key questions, although they are expressed in different ways. The purpose, method of approach, and conclusion of each generic task are described. It is hoped that conclusions will contribute a series of solutions, which, on integration with other researchers' efforts, will help answer the generic problems of deep burial of nuclear waste in a salt dome. Solutions to problems are possible primarily because of the extensive data base available on the East Texas Basin. For example, reconstructing the history of the infilling of the East Texas Basin can be accomplished because of thousands of electric logs and miles of seismic and regional gravity coverage. Similarly, the hydrologic studies have been facilitated greatly by the computerized data bank of the Texas Department of Water Resources. These data resources in general are not available equally for the Mississippi or North Louisiana Basins, and because of limited data, the questions of hydrologic and tectonic stability of salt domes may be difficult to answer adequately in those other parts of the Gulf Basin. We hope that the information in this report will be applicable, in a generic sense, to domes in other basins.

description: This work reports on the synthesis of chromium (III, IV) oxides films by KrF laser-assisted CVD. Films were deposited onto sapphire substrates at room temperature by photodissociation of Cr(CO)6 in dynamic atmospheres containing oxygen and argon. A study of the processing parameters has shown that partial pressure ratio of O2 to Cr(CO)6 and laser fluence are the prominent parameters that have to be accurately controlled in order to co-deposit both crystalline oxide phases. Films consistent with such a two-phase system were synthesised for a laser fluence of 75 mJ cm-2 and a partial pressure ratio about 1. PACS: 81.15.Fg, 81.15.Kk, 81.05.Je

description: A program to monitor baseline air and water quality, subsidence, microseismic activity, and noise in the vicinity of Brazoria County geopressured geothermal test wells, Pleasant Bayou #1 and #2, has been underway since March 1978 (fig. 1). The research findings for earlier work, including the results of an initial first-order leveling survey completed by Teledyne Geotronics, a preliminary microseismicity survey completed by Teledyne Geotech, and an archaeological survey of the site completed by Texas A&M University, have been previously reported and will not be repeated here. The initial report on environmental baseline monitoring at the test well contained descriptions of baseline air and water quality, a noise survey, an inventory of microseismic activity, and a discussion of the installation of a liquid tiltmeter (Gustavson, 1979). The second report continued the description of baseline air and water quality of the test well site, included an inventory of microseismic activity during 1979 with interpretations of the origin of the events, and discussed the installation and monitoring of a liquid tiltmeter at the test well site. Also, a brief description of flooding at the test site was presented. The following report continues the description of baseline air and water quality of the test well site, includes a summary of microseismic activity before and during 1980, and describes the monitoring of a liquid tiltmeter at the test well site (Gustavson and others, 1980).
