Sediment and Radiochemical Characteristics from Shore-Perpendicular Estuarine and Marsh Transects in the Grand Bay National Estuarine Research Reserve, Mississippi Sediment and Radiochemical Characteristics from Shore-Perpendicular Estuarine and Marsh Transects in the Grand Bay National Estuarine Research Reserve, Mississippi

To examine sediment transport and provenance between a marsh and estuary, surface sediments were collected along two transects in the Grand Bay National Estuarine Research Reserve, Mississippi (GNDNERR). Each shore-perpendicular transect consisted of fifteen surface samples, collected every 2.5 meters (m) from 10-m out into the estuary to 25-m into the marsh from the shoreline. Sediment...

Sediment budget data for Lees Ferry dune field, February-May 2019 Sediment budget data for Lees Ferry dune field, February-May 2019

These data were compiled to enable estimation of aeolian dune field sediment budgets calculated using remote sensing methods. The objective of the study was to evaluate sediment budgets calculated for the Lees Ferry dune field in Grand Canyon, Earth as a terrestrial analog for aeolian dune fields in Valles Marineris, Mars. These data represent digital elevation models (DEM) of the...

Sediment chemistry and characteristics of samples collected in 2019 from the Similkameen River above Enloe Dam, Okanogan County, Washington (ver. 3.0, March 2022) Sediment chemistry and characteristics of samples collected in 2019 from the Similkameen River above Enloe Dam, Okanogan County, Washington (ver. 3.0, March 2022)

This data release provides information on the chemistry and character of bed sediments accumulated in the 1.6-mile long impoundment behind Enloe Dam on the Similkameen River in Okanogan County, WA. Sediment samples were collected during four weeks in October – December 2019. The sampling locations were distributed among 10 transects that ranged from 0.1-0.2 miles apart along the length...

Sediment Deposition on Floodplains and Point Bars of Powder River in Southeastern Montana from 1979 through 2017 Sediment Deposition on Floodplains and Point Bars of Powder River in Southeastern Montana from 1979 through 2017

This data release consist of the annual sediment depositional volume at five floodplain and five point bar sites on Powder River in southeastern Montana from 1979 through 2017. These 10 sites are a subgroup of a larger group of cross-sections established in 1975 and 1977 to monitor the channel changes along a 90-kilometer reach of Powder River. In addition to the sediment deposition data...

Sediment Sample Data for Identifying and Monitoring Source Sediment Fingerprints within Stony Clove Creek, Catskills, NY from 2017 to 2020 Sediment Sample Data for Identifying and Monitoring Source Sediment Fingerprints within Stony Clove Creek, Catskills, NY from 2017 to 2020

This data release includes five comma delimited tables that support a pilot study on identifying and monitoring source sediment fingerprints within Stony Clove Creek, Catskills, NY. These tables consist of sediment particle size information, elemental analysis results, stable isotope analysis results, and percent fines for the samples collected. "SourceSamples_Info.csv" and...

Sediment trapping at "The Jaws" (TV-15): 2008, 2015, and 2018 land-water classifications Sediment trapping at "The Jaws" (TV-15): 2008, 2015, and 2018 land-water classifications

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...

Sedimentary geochemistry of a deepwater slope environment of southern Lake Tanganyika Sedimentary geochemistry of a deepwater slope environment of southern Lake Tanganyika

This dataset contains geochemical data (Total Inorganic Carbon, Total Organic Carbon, Total Nitrogen, δ13C of Organic Carbon, Hydrogen Index, Oxygen Index, Zirconium/Aluminum, and Magnetic Susceptibility) for sediments from one short (~1 m) core collected in 420 m of water in southern Lake Tanganyika, Tanzania.

Data consist of grain-size distribution by weight in grams of samples collected from the lectostratotype of the Yorktown Formation at Rushmere, Virginia, and from Pipsico Boy Scout Camp, Spring Grove, Virginia. In total, data from 45 samples is included.

Seed germination requirements and seed responses to salinity for three rare wetland plants of spring-fed arid systems at Bitter Lake National Wildlife Refuge near Roswell, New Mexico 2018-2020 Seed germination requirements and seed responses to salinity for three rare wetland plants of spring-fed arid systems at Bitter Lake National Wildlife Refuge near Roswell, New Mexico 2018-2020

Data includes seed germination experiments observations from seeds collected during the fall of 2018 and 2020 at Bitter Lake National Wildlife Refuge, near Roswell, New Mexico. Seeds of Cirsium wrightii, Agalinis calycina, and Helianthus paradoxus were collected by manually clipping seed heads from plants across the wetland management units. Seeds were placed in brown paper bags and...

This data release pertains to a seepage investigation and dye tracing study conducted in the Big Creek watershed of Newton County, Arkansas. The seepage dataset includes geospatial files of discharge measurement points and zero-flow observations along with vector lines delineating losing and gaining stream reaches. The dye tracing dataset consists of geospatial files of monitoring sites...

Seepage-run discharge measurements, November 15, 2021, He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i Seepage-run discharge measurements, November 15, 2021, He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i

This data release contains a comma-delimited ascii file of 16 discrete discharge measurements made at sites along selected reaches of He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i, on November 15, 2021. These discrete discharge measurements form what is commonly referred to as a "seepage run." The intent of the seepage run is to quantify the spatial distribution of streamflow along...
