Files are included for terrain hosting clay stratigraphies (CS), random Noachian and early Hesperian terrain (RNeH), random valley network terrain (RVN), al-clay detections (Al), and Fe/Mg clays (femg)
Flooding Frequency and Afterstorm Dune Recovery in Cedar Lakes' Washover
No full textThis dataset supports a project aimed at improving model-based understanding of dune erosion and post-storm recovery at the Cedar Lakes washover site on the Texas coast. The purpose of the study is to enhance coastal risk assessment and resilience planning through the use of models, long-term in-situ observations, and satellite imagery. The repository includes datasets and scripts developed for model calibration, validation, and visualization. It is organized into two main components: the data files, which include raw and processed datasets categorized by source and type, and the analysis scripts, which contain code for data processing, modeling, and result visualization. Together, these materials support research in coastal morphology, sediment transport, and nature-based coastal management strategies
NSF COLDEX 2022-2023 Airborne Season (CXA1): Level 1B Serial Instrument Measurements
No full textNSF COLDEX CXA1 laser ranging, magnetic field strength and orientation, and positioning
This data collection represents georeferenced, time registered instrument measurements (Level 1B data) converted to SI units, and is of most interest to users who wish to reprocess the data. Users interested in geophysical observables (eg magnetic anomalies and surface elevation) should used the derived Level 2 datasets. The data format are space delimited ASCII files, following the formats used for UTIG predecessor ICECAP/OIB project at NASA's NSIDC DAAC. Fields are described in the # delimited detailed header for each granule.
DATASET ORGANIZATION
Transects were collected in preplanned systems with the following parameters:
CLX radials (CLX/MKB##/R###), attempting to emulate flow lines from Dome A and radiating (in the EPSG:3031 polar stereographic projection) from easting 965 km northing 385 km, with a separation of 0.25 degrees.
CLX corridor (CLX/MKB##/X###) rotated from the EPSG:3031 polar stereographic projection at -150 degrees and separated by 10 km in the Y direction and 3.75 km in the X direction.
CLX2 corridor (CLX2/MKB##/X###) rotated from the EPSG:3031 polar stereographic projection at -150 degrees and separated by 2.5 km in its Y direction and 2.5 km in its X direction.
SAD corridor (SAD/MKB##/X###|Y####) designed to characterize the Saddle region near South Pole approximately perpendicular to the flow lines, rooted from the EPSG:3031 polar stereographic projection at -73.8 degrees and separated by 2.5 km in its Y direction and 2.5 km in the its X direction.
Untargeted transit lines used the name of the expedition (CXA1) as the project, and used the flight and the increment within the flight to name the Transect (eg (CXA1/MKB2n/F10T02a).
POSITIONING
GPS provides the positioning (and timing) for all other data streams:
IPUTG1B (ICECAP Positioning/UTIG GPS Level 1B): real time CA-code 1 Hz GPS position data
MAGNETICS
Magnetic data provides constraints on the depth to crystalline rock, the temperature structure of the crust, and the underlying tectonics
IMGEO1B (ICECAP Magnetics: Geometrics Level 1B): georeferenced total magnetic field data; 10 Hz ASCII
IMFGM1B (ICECAP Magnetics/Flux Gate Magnetometer Level 1B): georeferenced aircraft referenced magnetic field vectors; 10 Hz ASCII
ALTIMETRY
Laser altimetry provides for surface shape and altimetry validation. See COLDEX 2022-23 Riegl Laser Altimeter Level 2 Geolocated Surface Elevation Triplets for derived surface elevation data.
ILUTP1B (ICECAP Lidar/UTIG Profiler Level 1B): georeferenced laser range data, no orientation corrections; 3.5 Hz ASCII

Climate-Smart Agriculture Adoption in Texas
No full textThe data represents yearly, non-irrigation treated or "dryland", averages and sums of Texas-county data concerning upland cotton (containing production, acres plotted, and acres harvested) and drought data for the subsequent counties used.
The key unique factor in this dataset is the "Aquifer Group" column, which specifies whether the counties for which the data was used was in the top or bottom 20% of counties above groundwater areas.
Useful for examining groundwater impacts on crop yields

A few derivations related to convolution and inter-conversion for linear visco-elastic materials
No full textThis article presents a heuristic derivation of the convolution integral, which is a critical concept in solving mechanistic problems related to linear viscoelastic materials. This article also presents the derivations for inter-conversions from time to frequency dependent responses. In the context of this article, viscoelastic response is considered to be synonymous with time-dependent response.

Latin American Press Review, Program 1974-11, 1974 February 28
No full textPart I: The Latin American Press Review covers Peru's compensation to U.S. companies, Nixon's attempts to resolve investment disputes, controversy over Joseph Jova's appointment as U.S. ambassador to Mexico, and Chile's military junta's suspension of political activities. Additionally, the International League of Women for Peace and Liberty reports on secret military tribunals in Chile sentencing former officials to death. There's a surge in U.S. arms sales to Latin America and controversy surrounding American police training programs abroad. In Argentina, collaboration between right-wing terrorist groups and the government leads to internal conflicts within the Peronist movement, driving moderates towards radical factions. Part II: Christopher Roper discusses U.S. foreign policy towards Latin America, highlighting his newsletter's independence and reliance on Latin American sources. Roper critiques U.S. media for their government-centric perspectives and limited interactions in the region. He suggests a shift in Latin American views towards the U.S., with desires for improved relations with Cuba and potential policy changes. Roper notes Kissinger's efforts to redirect focus from divisive issues and Nixon's ties hindering policy shifts towards Cuba. He expresses skepticism about resolving disputes over expropriation in Peru due to intertwined interests and Peru's reluctance influenced by events in Chile. The discussion underscores historical challenges in U.S.-Latin American relations, with potential complexities persisting. Files include CSVs of the annotated transcriptions and lists of places, people, organizations, subjects, and media sources mentioned in the radio program
