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) 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...
Rock mass quality and structural geology observations in Glacier Bay National Park and Preserve, Alaska from the summers of 2021 and 2022 Rock mass quality and structural geology observations in Glacier Bay National Park and Preserve, Alaska from the summers of 2021 and 2022
Subaerial and submarine landslides adjacent to, and within, Glacier Bay, Glacier Bay National Park and Preserve (GBNPP), Alaska pose a threat to the public because of their potential to generate ocean waves that could impact marine activities. Although historical records of tsunamis generated by landslides in GBNPP are uncommon, there are records that document the destructive power of at...
Snow Measurements in Specific Canopy Structure Regimes for April 9, 2024, North of Coal Creek, San Juan Mountains, Colorado, USA Snow Measurements in Specific Canopy Structure Regimes for April 9, 2024, North of Coal Creek, San Juan Mountains, Colorado, USA
These data include snow depth and snow water equivalent (SWE) for a field campaign on April 9, 2024. The field area is comprised of 311 surveyed points in, on the perimeter of, and surrounding six forest openings next to Coal Creek off Coal Bank Pass in the San Juan Mountains in southwestern Colorado, USA. These measurements were taken to look at the relationship between snow...
High-resolution bathymetry and backscatter data collected at eighteen spawning reefs in NE Lake Michigan using a Norbit iWBMSh multibeam echosounder, 2021-2023 (UTM Zone 16N, NAD 83, NAVD 88) High-resolution bathymetry and backscatter data collected at eighteen spawning reefs in NE Lake Michigan using a Norbit iWBMSh multibeam echosounder, 2021-2023 (UTM Zone 16N, NAD 83, NAVD 88)
Eighteen lakebed areas in northern Lake Michigan known to be used by adult fishes for spawning were surveyed between 2021 and 2023 using a Norbit® iWBMSh multibeam echosounder to support fisheries habitat assessment. More than 3500 kilometers of high resolution multibeam data were collected with 0.05m horizontal and 0.5m vertical positional accuracy, with 100% overlap between survey...
Cameron-Creole Maintenance (CS-04a): 2021 land-water classification Cameron-Creole Maintenance (CS-04a): 2021 land-water classification
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...
