title: Comparison of soil water content estimation equations using ground penetrating radar

description: Soil water content has an important impact on many fundamental biophysical processes. Many techniques are available today for measuring soil water content, ranging from point scale soil water content sensors to global scale, active and passive, microwave satellites. Geophysical methods are important methods, used for several decades, to measure soil water content at different scales. Among these methods, ground penetrating radar has been shown to be one of the most reliable and promising ones. Soil water content measurement using ground penetrating radar requires the application of parametric equations that will convert the measured dielectric permittivity to water content. While several studies have been performed to test equations for soil water content sensors such as time domain reflectometry, a few studies have been performed to test different formulae for application to ground penetrating radar. In this study, we compare available formulae for converting dielectric permittivity obtained from detailed laboratory scale measurement of reflected waves using ground penetrating radar. Four soils covering a wide range of textures were used and the measured soil water contents were compared with values obtained from gravimetric measurements. Results showed that the dielectric mixing model of Roth et al. (1990) provided the best fit for individual soil textural classes, except for sandy soils. However, for all data combined the dielectric mixing model performed much better with significant difference in coefficient and determination and root mean square error. Empirical equations developed from calibration of time domain reflectometry performed poorly when applied to estimation of soil water content obtained from ground penetrating radar. Differences in sample volume, frequency of operation and data analysis between ground penetrating radar and time domain reflectometry, suggest to use more flexible and robust electromagnetic mixing formulae, allowing for incorporating the dielectric properties of constituents materials and geometrical features of the media. Sensitivity analysis was then performed to provide detailed information for the most accurate application of the selected dielectric model.

description: Oxygen and carbon isotope records from benthic and planktonic foraminifera are presented for the past 35,000 years in the northeastern Atlantic. The results support the idea that the last deglaci-ation took place in two major steps (Duplessy et al., 1981 doi:10.1016/0031-0182(81)90096-1; Mix and Ruddiman, 1985 doi:10.1016/0277-3791(85)90015-0; Ruddiman, 1987; Fairbanks, 1989 doi:10.1038/342637a0), and conflict with theories calling for a strong reduction in North Atlantic deep-water formation to explain the abrupt cooling of the Younger Dryas cold period (Broecker et al., 1985 doi:10.1038/315021a0; Rind et al., 1986 doi:10.1007/BF01277044; Broecker et al., 1988 doi:10.1029/PA003i001p00001).

title: Airborne electromagnetic, magnetic, and radiometric survey of the Mississippi Alluvial Plain, Mississippi Embayment, and Gulf Coastal Plain, September 2021 - January 2022

description: Airborne electromagnetic (AEM), magnetic, and radiometric data were acquired September 2021 to January 2022 along 27,204 line-kilometers (line-km) over the Mississippi Alluvial Plain (MAP), Mississippi Embayment, and Gulf Coastal Plain. Data were acquired by Xcalibur Multiphysics (Canada), Ltd. with three different airborne sensors: the 30Hz TEMPEST time-domain AEM instrument that is used to map subsurface geologic structure at depths up to 300 meters (m) depending on the subsurface resistivity; a Scintrex CS-3 cesium vapor magnetometer that detects changes in deep (hundreds of meters to kilometers) geologic structure based on variations in the magnetic properties of different formations; and a Radiation Solutions RS-500 spectrometer that detects the abundance of natural radioelements potassium, uranium, and thorium in the upper 20-30 centimeters that is used to determine differences in soil constituents. The survey was flown at a nominal sensor flight height of 120 m above terrain with 300 and 600 km (nominal) spaced east-west flight lines. The main survey block covers 24,654 line-km. The Chicot aquifer focus area was surveyed along 360 line-km (flight numbers 2900101-2900421 nonsuccessive). The Mississippi River and the Atchafalaya River were surveyed along their center axes, covering 742 line-km (flight line numbers 6004001-6004003 and 5002001-5002002). Two separate inset grids were flown: (1) University of Memphis (UMemphis) focus area lines with 500 m line spacing for a total of 1260 line-km (flight line numbers 1000301-1030001 nonsuccessive), and (2) Hot Springs focus area with 350 m line spacing for a total of 188 line-km (flight line numbers 2001001-2027001 nonsuccessive). 91-series lines are repeat test-lines flown periodically throughout the survey, with one repeat line established for each base station. 901- and 904-series lines are flown under standard survey conditions with the transmitter on and the receiver off to evaluate the noise contribution from the acquisition system pre- and post- flight, respectively. 902- and 905-series lines are ~60 second high-altitude datasets collected to evaluate the system out of ground-response pre- and post- flight, respectively. 903-series lines are 30-40 second 'swoop' datasets to confirm correct operation of the system during variable pitch manoeuvres. 906-series lines are flown under standard survey conditions with the transmitter off and the receiver on to evaluate the ambient noise in the system. AEM data were inverted using 1-D inversion to produce models of electrical resistivity along flight paths.

title: Vegetation Types in Coastal Louisiana in 2021 (ver. 2.0, April 2023)

description: Coastwide vegetation surveys have been conducted multiple times over the past 50 years (e.g. Chabreck and Linscombe 1968, 1978, 1988, 1997, 2001, and 2013) by the Louisiana Department of Wildlife and Fisheries (LDWF) in support of coastal management activities. The last survey was conducted in 2013 and was funded by the Louisiana Coastal Protection and Restoration Authority (CPRA) and the U.S. Geological Survey (USGS) as a part of the Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) monitoring program. These surveys provide important data that have been utilized by federal, state, and local resource managers. The surveys provide information on the condition of Louisiana's coastal marshes by mapping plant species composition and vegetation change through time. During the summer of 2021, the U.S. Geological Survey, Louisiana State University, and the Louisiana Department of Wildlife and Fisheries jointly completed an aerial survey to collect data on 2021 vegetation types in coastal Louisiana in the same manner as the 2013 survey. Plant species were identified and their abundance classified. Based on species composition and abundance, each marsh sampling station was assigned a marsh type: fresh, intermediate, brackish, or saline marsh. The current map presents the data collected in this effort.

description: Benthic foraminiferal delta13C suggests that there was a net shift of isotopically light metabolic CO2 from the upper ocean into the deep ocean during the last glacial period. According to the 'CaCO3 compensation' hypothesis, this should have caused a transient drop in deep ocean CO3[2-] that was eventually reversed by seafloor dissolution of CaCO3. The resulting increase in whole-ocean pH may have had a significant impact on atmospheric CO2, compounding any decrease that was due to the initial vertical CO2 shift. The opposite hypothetically occurred during deglaciation, when CO2 was returned to the upper ocean (and atmosphere) and deep ocean CO3[2-] temporarily increased, followed by excess burial of CaCO3 and a drop in whole-ocean pH. The deep sea record of CaCO3 preservation appears to reflect these processes, with the largest excursion during deglaciation (as expected), but various factors make quantification of deep sea paleo-CO3[2-] difficult. Here we reconstruct deep equatorial Pacific CO3[2-] over the last glacial-interglacial cycle using benthic foraminiferal Zn/Ca, which is strongly affected by saturation state during calcite precipitation. Our data are in agreement with the CaCO3 compensation theory, including glacial CO3[2-] concentrations similar to (or slightly lower than) today, and a Termination I CO3[2-] peak of ~25-30 µmol kg**-1. The deglacial CO3[2-] rise precedes ice sheet melting, consistent with the timing of the atmospheric CO2 rise. A later portion of the peak could reflect removal of CO2 from the atmosphere-ocean system due to boreal forest regrowth. CaCO3 compensation alone may explain more than one third of the atmospheric CO2 lowering during glacial times.

title: AOTIM5: Arctic Ocean Inverse Tide Model, on 5 kilometer grid, developed in 2004

description: The 5 kilometer (km) Arctic Ocean Tidal Inverse Model developed in 2004 (AOTIM5) is a barotropic tide model on a polar stereographic grid. AOTIM5 was created using the OSU Tidal Inversion Software (OTIS) package (https://www.tpxo.net/). Model development is described by Padman and Erofeeva (2004) (https://doi.org/10.1029/2003GL019003). The bathymetry grid is based on the original International Bathymetric Chart of the Arctic Ocean (IBCAO) bathymetry (Jakobsson et al., 2000; https://doi.org/10.1029/00EO00059). AOTIM5 consists of grids of sea surface height and depth-integrated currents (“volume transports”) for each of 8 tidal constituents; 4 semidiurnal (M2, S2, K2, N2) and 4 diurnal (K1, O1, P1, Q1). The first step in building AOTIM5 was development of the Arctic Ocean Dynamics-based Tide Model (AODTM5), which is also available at the Arctic Data Center (https://arcticdata.io/catalog/view/doi:10.18739/A2901ZG3N). That model was forced at open ocean boundaries by the TOPEX/Poseidon global barotropic tidal solution version 6.2 (TPXO.6.2), and by local astronomical forcing (“potential tides”). Each constituent in AODTM5 was tuned, separately, to Arctic tide height data by optimizing the linear drag coefficient. AOTIM5 used AODTM5 as a “prior” model, then assimilated coastal and benthic tide gauges, and TOPEX/Poseidon and ERS satellite radar altimetry, to improve the 4 largest-amplitude constituents, M2, S2, K1 and O1.
 An updated version of this model created in 2018, Arc5km2018, is also available at the Arctic Data Center. The newer model uses updated open boundary conditions, and a wider range of assimilated data including much longer satellite altimetry records. We recommend that users compare results from AOTIM5 and Arc5km2018 before deciding which to use for a specific application. Please also check the ESR Polar Tide Model webpage (https://www.esr.org/research/polar-tide-models/) for more recent Arctic barotropic tide models.

title: Overview video
title: Brightness extracted from pictures

description: This repository hosts data obtained from high-speed camera measurements conducted within a large powder snow avalanche (No. 20213009) that occurred naturally at the Vallée de la Sionne test site in Switzerland. Positioned 14 meters above the ground on a vertical pylon, the high-speed camera captures visualizations of snow particles within the aerial layers. These images reveal diverse particle clusters, identifiable as bright spots due to their higher light reflectance compared to the surrounding air-snow crystal mixture.

Contained within this repository is an overview video recording along with corresponding data on the average brightness of each image captured by the high-speed camera. This dataset facilitates the reconstruction of the temporal evolution and frequency of particle clustering, with brightness intensity acting as a proxy for mass transport. The average brightness for each image is computed from the averaging of values from 2048 x 2048 pixels (greyscale 0 to 255). These datasets complement the findings presented in the following publication:
