Airborne magnetic and radiometric survey, central Arkansas - southern Missouri, 2023

This publication provides digital flight line data for a high-resolution magnetic and radiometric survey over part of central Arkansas and southern Missouri. The airborne geophysical survey was funded by the Earth Mapping Resources Initiative and was designed to meet the complimentary needs related to geologic mapping and mineral resource research.  The survey covers an irregularly shaped area of approximately 75,070 square kilometers (km^2) from southern Missouri, across part of the Arkoma basin and Ouachita Mountains into central Arkansas and includes 282,029 line-km of magnetic and radiometric data. Data were collected from fixed-wing aircraft flown at a median terrain clearance of 115 meters (m) above topography along north-south flight lines spaced at 300-m intervals. Tie lines were flown in an east-west direction every 3,000 m. Data were collected by EON Geosciences Inc. under contract with the USGS using five fixed-wing aircraft with a magnetometer mounted in the tail stinger and a fully calibrated gamma-ray spectrometer. The survey operated out of the Branson Airport in Missouri, the West Memphis Municipal Airport in Tennessee, and the North Little Rock Municipal and Texarkana Regional Airports in Arkansas from November of 2022 to May of 2023. Files that are available in this publication include flight line data for the magnetic survey, flight line data for the radiometric survey and a report describing the survey parameters, field operations, quality control and data reduction procedures. A zip file is provided that contains the contractor's deliverable products that includes Geosoft databases and grids for this magnetic and radiometric survey and the report describing the survey and data reduction. These products can be accessed using the free software Geosoft Viewer or the commercial Oasis montaj software.

Vegetation and soil cover data in response to indaziflam and imazapic herbicide applications within Minidoka National Wildlife Refuge, Idaho, USA

Eighty-one monitoring plots within the Minidoka National Wildlife refuge on the Snake River Plain in south-central Idaho were surveyed in July-August from 2020 to 2023 to evaluate the effects of herbicides on the vegetation-community  across areas that varied in both burn history and background cheatgrass abundance. Surveys consisted of line-point intercept measurements along two 6m or 50m transects with 100 points of observation per line. In spring of 2023 "escaped" cheatgrass individuals were counted in each 6x6m herbicide-treated plot.

Undersized Fire Mapping Program Thematic Burn Severity Mosaic for CONUS in 1984

This map layer is a thematic raster image of MTBS burn severity classes for all inventoried fires occurring in CONUS during calendar year 1984 that do not meet standard MTBS size criteria. These data are published to augment the data that are available from the MTBS program. This product was produced using the methods of the Monitoring Trends in Burn Severity Program (MTBS), however these fires do not meet the size criteria for a standard MTBS assessment. The MTBS Program assesses the frequency, extent, and magnitude (size and severity) of all large wildland fires (wildfires and prescribed fires) in the conterminous United States (CONUS), Alaska, Hawaii, and Puerto Rico for the period 1984 and beyond. MTBS typically maps fires using an initial assessment (immediately after the fire) or an extended assessment (peak of green the season after the fire) for low-biomass and high-biomass fires respectively. Refer to MTBS.gov for more information on MTBS methods and criteria. Standard MTBS mappings must meet the size criteria of at least 500 acres for the eastern states and territories and 1,000 acres for the western states and territories to be eligible for mapping. Undersized MTBS fires are those fires that do not meet the standard MTBS size criteria but are otherwise mapped using standard MTBS methodologies.

Airborne Magnetic Geophysical Survey of the Porcupine River Area, Alaska

The Porcupine River fixed wing aeromagnetic geophysical survey is located in eastern Alaska, along the Canadian border, in the Sheenjek and Black mining districts. This survey is located about 135 kilometers east of Fort Yukon, Alaska and about 85 kilometers east of Circle, Alaska. Magnetic data were collected with a Geometrics G-822A cesium-vapor split-beam sensor mounted in a tail stinger. Between May 5th and June 28th, 2017, a total of 50,329 line kilometers were collected covering 13,646.9 square kilometers. Data were collected at a line spacing of 300 meters (m) with a mean ground clearance of 235 m. The data, as well as additional metadata, are available from the DGGS website: https://doi.org/10.14509/29737.

Pathological findings in corals from the US Virgin Islands

Stony coral tissue loss disease (SCTLD) was first documented in Florida in 2014 and has since spread through the Caribbean causing unprecedented mortality in over 20 species of corals.  The cause of SCTLD is unknown, but bacteria are suspected based on regression of gross lesions in some corals treated with antibiotics.  Limited pathology studies on SCTLD exist, but it is likely that ‘SCTLD’ is a general term encompassing tissue loss disease of unexplained origin.  Here, we examined pathology of lesions in corals from the USVI where SCTLD has recently emerged.  The typical histologic lesion of SCTLD in Florida corals was lytic necrosis comprising vacuolation and necrosis of mucus cells with erosion of mesoglea and misshapen endosymbionts with variably sized intracytoplasmic granules and common occurrence of filamentous viral-like particles in endosymbionts visible on electron microscopy (EM).  In contrast, USVI corals had mainly mucus cell lytic hypertrophy and necrosis with no involvement of mesoglea, endosymbiont pathology at the light microscopy level was less evident, and VLP were rarely seen on EM. We suspect SCTLD is likely more complex with multiple presentations and potential etiologies depending on geographic region.  Further pathological studies from other regions might help refine the case definition of SCTLD.

Particle size distribution data from Florida Bay, Everglades National Park, Florida - 2024 analyses of samples collected following Hurricane Irma (2017) (ver. 1.1, May 2025)

In January 2018, a U.S. Geological Survey (USGS) team collected short cores and surface samples from four islands in Florida Bay, Everglades National Park, south Florida (Wingard et al. 2019). The 2018 samples were collected approximately five months after the passage of Hurricane Irma on September 10, 2017, as a category 4 storm. The four islands had also been cored in 2014. The goal of the long-term study of these four islands is to examine the impacts of climate and sea level on island formation and resilience, and to provide insights into the stability of the south Florida coastline. The passage of Hurricane Irma provided an opportunity to sample sediments deposited by the storm surge. 
The particle size analysis (PSA) data presented here contain results from three types of samples: 1) a short core (20 cm) collected from the western-most of the four islands (Jim Foot Key); 2) surface samples, representing overwash deposits from the storm surge collected from the four islands (Jim Foot Key, Buttonwood Key #7, Bob Allen Key, and Russell Key); and 3) basin samples from Florida Bay mudbanks and deeper water surrounding the islands. The basin samples were collected in December 2020 for comparison to the storm deposits to investigate possible provenance. The three types of samples were photographed and described prior to splitting and/or subsampling for PSA, which was conducted using the Beckman Coulter LS 13 320 XR laser diffraction analyzer housed in the Bascom Laser Diffraction Sedimentology Laboratory in Reston, VA.
The work described here is done in collaboration with Everglades National Park (Study #EVER-00617) and is funded by the Greater Everglades Priority Ecosystem Science program of the USGS.
