Pass Chaland to Grand Bayou Pass Barrier Shoreline Restoration (BA-35) Coastal Wetlands Planning, Protection and Restoration Act 2021 detailed habitat classification Pass Chaland to Grand Bayou Pass Barrier Shoreline Restoration (BA-35) Coastal Wetlands Planning, Protection and Restoration Act 2021 detailed habitat classification
The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana’s Coastal Protection and Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring Program (SWAMP). The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands...
Phytoplankton and Cyanotoxin Data for Coastal and Shoreline Areas of National Parks, 2021-2024 Phytoplankton and Cyanotoxin Data for Coastal and Shoreline Areas of National Parks, 2021-2024
This U.S. Geological Survey (USGS) data release contains phytoplankton classification and enumeration results from near-surface water samples collected during a nationwide harmful algal bloom (HAB) monitoring effort in partnership with the National Park Service (NPS) Water Resources Division. Samples were collected during the 2021-2024 monitoring seasons from 26 National Parks across the...
Water quality concentration and load data for a biofilter at Green Tech Station in Milwaukee, Wisconsin, 2022–24 Water quality concentration and load data for a biofilter at Green Tech Station in Milwaukee, Wisconsin, 2022–24
The U.S. Geological Survey conducted a study in Milwaukee, Wisconsin, to evaluate the performance of a biofilter designed to treat urban stormwater runoff from a roadway. This data release includes load calculations for total suspended solids, nutrients, major ions, and 12 metals for monitoring that ran from March, 2022 to November, 2024. Loads are reported for both the inlet (USGS site...
Sample details and compositional data collected during episodes 1–39 (2024-2025) of the 2024-ongoing episodic Halema‘uma‘u eruption of Kīlauea, Island of Hawaiʻi Sample details and compositional data collected during episodes 1–39 (2024-2025) of the 2024-ongoing episodic Halema‘uma‘u eruption of Kīlauea, Island of Hawaiʻi
Samples for episodes 1–39 (2024-2025) of the 2024-ongoing episodic Halema‘uma‘u Kīlauea eruption were collected by the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) field teams from within publicly closed areas of Hawai‘i Volcanoes National Park in cooperation with the National Park Service. This data release presents sample metadata, whole rock ED-XRF, whole rock WD-XRF...
Monthly Raster Imagery, Historic Wetland Boundaries, and Management Period Mean Images for the Cebolla Spring Wetland in New Mexico Monthly Raster Imagery, Historic Wetland Boundaries, and Management Period Mean Images for the Cebolla Spring Wetland in New Mexico
Alluvial wetland ecosystems, such as the Cebolla Creek spring-fed wetland in east-central New Mexico, serve as biodiversity hotspots and directly affect processes such as water cycling and carbon sequestration. However, these systems are highly vulnerable to degradation because of drought, groundwater pumping, and channel incision. The "Zeedyk" approach for restoration employs methods...
Ultraviolet remote sensing data from a spectrometer fenceline array (DFence) installed at Kīlauea for measuring volcanic gas emissions Ultraviolet remote sensing data from a spectrometer fenceline array (DFence) installed at Kīlauea for measuring volcanic gas emissions
In 2012, the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) installed an array of zenith-pointing ultraviolet spectrometers to track gas emissions from summit of Kīlauea (Businger et al., 2015; Elias et al., 2018). The instruments are arranged in an arc perpendicular to the dominant trade-wind direction approximately 2 kilometers (km) southwest of the actively degassing...
