TxSON — Texas Soil Observation Network
No full textThe Texas Soil Observation Network (TxSON) is an intensively monitored area (1300 km²) located near Fredericksburg, Texas within the middle reaches of the Colorado River. The area typifies the dissected, carbonate-rock terrain of the Texas Hill Country with semiarid rangelands of mixed oak/grasslands and juniper woodlands. TxSON consists of 40 soil moisture monitoring stations nested at 3, 9 and 36 km within the Equal-Area Scalable Earth Grid. Beginning in 2015, the complete data set consists of a decade long record of mean hourly volumetric soil water content and soil temperature measured at 5, 10, 20 and 50 cm depths (when possible). Precipitation is measured at all locations with meteorological stations also providing air temperature and humidity, wind speed and direction, and solar radiation. Filename includes the end date of the data record for operational stations (decommissioned stations have earlier end dates)

3D Monte Carlo radiative transfer simulations for fractal-shaped cloud patterns
No full textThe Monte Carlo Atmospheric Radiative Transfer Simulator (MCARaTS) is used to perform 3D radiative transfer simulations for 4 different fractal-shaped cloud patterns to study how horizontal radiative energy exchanges between cloud-free and cloudy regions vary with cloud fraction and normalized cloud perimeter length
Latin American Press Review, Program 1974-09, 1974 January 13
No full textPart I: Discussions between Latin American foreign ministers and US Secretary of State Henry Kissinger, focus on key issues such as the role of US multinational corporations, Latin America's technological dependency on the US, and the restoration of Panama's sovereignty over the canal zone. Speculation regarding a potential shift in Cuba's attitude towards the US is also addressed, alongside calls for a change in US policy towards Cuba. Part II: The analysis provides insights into Argentina's political landscape, highlighting Juan Perón's influential career and the challenges he faces in maintaining power amid economic and social conflicts. Tensions between left-wing factions and the Peronist trade union hierarchy are explored, alongside the emergence of new left-wing organizations and recent urban guerrilla activity. Lastly, reports of massive Brazilian military maneuvers in the Amazonian region raise concerns among neighboring countries, particularly Venezuela, with allegations of Brazilian expansionist plans sparking calls for inquiries into Brazilian penetration of Venezuelan territory.

Latin American Press Review, Program 1974-07, 1974 January 30
No full textPart I: Recent events across Latin America, focusing on key developments in Peru, Argentina, Bolivia, and Chile. In Peru, President Velasco's proposal for a regional arms limitation pact aims to redirect military spending towards development, facing mixed reactions from neighboring countries. In Argentina, President Perón's shift towards conservatism prompts social unrest, exacerbated by guerrilla attacks. Part II: Chile, under the military junta, faces severe repression, economic hardship, and international criticism. The junta's crackdown on dissent triggers resistance efforts despite challenges, with the report highlighting ongoing struggles for democracy and human rights in the region. Files include CSVs of the annotated transcriptions and lists of places, people, organizations, subjects, and media sources mentioned in the radio program

Pogue Springs Dye Trace Report, Western Travis County, Texas
No full textThis technical report details a dye trace study conducted in and around Milton Reimers Ranch Park, western Travis County, Texas, initiated in April 2024. The study’s primary objective was to refine the existing conceptual hydrogeologic model of the Middle Trinity Aquifer, specifically within the Pogue Creek Watershed. This effort is crucial for developing regulatory and conservation strategies to preserve the diminishing groundwater levels and springflow in the region, which are threatened by persistent drought and excessive groundwater pumping. We injected three distinct fluorescent dyes—fluorescein, rhodamine WT, and eosine—at three sites within the Pogue Creek watershed: a natural recharge feature (swallet) and two wells. Dye monitoring occurred at 12 spring, stream, and well locations across four watersheds, primarily using activated charcoal detectors and, in some cases, field fluorimeters. The study aimed to delineate local springsheds by testing if groundwater from the Pogue Creek Watershed flows exclusively to Pogue Spring or also to springs in neighboring watersheds. Results indicate successful detection of only one dye, eosine, injected into the Reimers Park Abandoned Windmill Well. This dye was detected at Pogue Spring, located approximately 594 feet away, between 116 and 156 days post-injection, and has persisted for at least 150 days. Therefore, the estimated average groundwater velocity between the injection well and Pogue Spring is 4.5 ft/day. Dye was only detected via cumulative absorption on charcoal samples, as concentrations in water samples remained below the method detection limit. Field fluorimeters did not detect dye, showing false positives correlated with rainfall and likely sources of natural fluorescence. The observed groundwater velocity, while slower than typical conduit flow in karst systems, is faster than estimated matrix flow alone through limestone, suggesting components of conduit and fracture flow in addition to matrix flow within the Cow Creek Limestone. This study validates the existing conceptual model of a karstic Upper Cow Creek Limestone and highlights the hydrologic heterogeneity between the Upper and Lower Cow Creek units
