Sediment Core Microfossil Data Collected from the Coastal Marsh of Grand Bay National Estuarine Research Reserve, Mississippi, USA Sediment Core Microfossil Data Collected from the Coastal Marsh of Grand Bay National Estuarine Research Reserve, Mississippi, USA
To aid in geologic studies of sediment transport and environmental change of a coastal marsh, 1-centimeter (cm) foraminiferal subsamples were taken from seven sediment push cores collected in the Grand Bay National Estuarine Research Reserve (GNDNERR), Mississippi (MS), in October 2016. The push cores were collected along two, shore-perpendicular transects at 5, 15, 25, and 50 meters (m)...
Sediment grain size, geochemistry, and polychaete functional traits of Norfolk Canyon (western Atlantic) axis, hard substrate, and adjacent slope habitats, 2012-2013 Sediment grain size, geochemistry, and polychaete functional traits of Norfolk Canyon (western Atlantic) axis, hard substrate, and adjacent slope habitats, 2012-2013
Dataset of sediment geochemistry, water column parameters, and macrofaunal functional traits associated with sediment communities collected in Norfolk Canyon axis, hard substrates, and adjacent slope habitats in 2012 and 2013.
Sediment grain-size data from the Klamath estuary, California Sediment grain-size data from the Klamath estuary, California
This data release includes grain-size measurements of sediment samples collected from the substrate surface and uppermost 10 cm of sediment deposits in the Klamath estuary, northern California. Samples were collected using a BMH-60 bed-material sampler deployed from a boat, or by hand trowel from subaerial or shallow-water (less than 0.5 m water depth) regions along the estuary margins...
Sedimentologic Data from Point aux Chenes Marsh and Estuary, Mississippi Sedimentologic Data from Point aux Chenes Marsh and Estuary, Mississippi
Sediment samples, including marsh and estuarine surface samples and marsh push and peat-auger cores, were collected from Point aux Chenes, Mississippi from October 23–26, 2018, and August 4, 2021. Marsh surface samples (top 1 centimeter (cm) of sediment; sample names appended with S), marsh push cores (core names appended with M) and peat-auger cores (core names appended with R) were...
Sedimentological and geotechnical analyses of marine sediment cores from the New England Mud Patch Sedimentological and geotechnical analyses of marine sediment cores from the New England Mud Patch
Variability in sediment properties with depth and the thickness of individual sedimentary layers are critical determinants of seabed acoustic response. The New England Mud Patch, located south of Cape Cod, is an unusual feature on the U.S. Continental Shelf in that it is composed of fine-grained sediment layers containing a relatively-homogeneous mix of sand, silt, and clay-sized...
Seed and Associated Tree Data from Long Term Research Plots in Sequoia and Yosemite National Parks (ver. 2.0, December 2024) Seed and Associated Tree Data from Long Term Research Plots in Sequoia and Yosemite National Parks (ver. 2.0, December 2024)
This dataset was used as part of a continent-wide analysis of tree fecundity and its association with climate and tree size. This dataset consists of: plotinfo.csv, which contains basic attribute information for the field plots where the data were collected; seeddata.csv, which contains the data for seeds collected (how many, what type, etc.); trapxycoord.csv, which contains location and
Seed source, not drought, determines patterns of seed production in Sierra Nevada conifers Seed source, not drought, determines patterns of seed production in Sierra Nevada conifers
This release consists of data collected from 26 plots in two national parks over a 19-year period. The data consists of plot-level seed counts for three genera, number of seed traps, live tree basal area, plot area, and climate metrics from the gridmet gridded data set, the daymet gridded data set, the PRISM gridded data set, and two nearby COOP stations.
Seepage meter efficiency in highly permeable settings source data (2020) Seepage meter efficiency in highly permeable settings source data (2020)
Efficiency of seepage meters, long considered a fixed property associated with the meter design, is not constant in highly permeable sediments. Instead, results from this study indicate that efficiency varies substantially with seepage-bag fullness, duration of bag attachment, depth of meter insertion into the sediments, and seepage velocity. Efficiency also varies substantially in...
Seine Collection Data Along the Michigan Shoreline of the St. Clair-Detroit River System Seine Collection Data Along the Michigan Shoreline of the St. Clair-Detroit River System
These data contain counts of fish species collected with a 1.83 m x 9.14 m bag seine constructed of 1.6 mm Delta nylon mesh. When permitted, five consecutive 15.25 m hauls were made parallel to the shoreline. Sites with smaller shorelines were sampled to the greatest extent possible and distance recorded. The seine was pulled in the upstream direction to allow the net to stay open during...

Select model results from simulations of hypothetical rapid failures of landslides into Barry Arm, Prince William Sound, Alaska Select model results from simulations of hypothetical rapid failures of landslides into Barry Arm, Prince William Sound, Alaska
This data release contains model output from simulations presented in the associated Open-File Report (Barnhart and others, 2021). In this report, we present model results from four simulations (scenarios C-290, NC-290, C-689, NC-689, Table 1) of hypothetical rapid movement of landslides into adjacent fjord water at Barry Arm, Alaska using the D-Claw model (George and Iverson, 2014...
Selected borehole geophysical logs from three contaminant sites in California, Wisconsin, and New Jersey Selected borehole geophysical logs from three contaminant sites in California, Wisconsin, and New Jersey
Borehole geophysical logs were collected to characterize bedrock aquifers at three contamination sites located in California, Wisconsin, and New Jersey. The data were collected by the U.S. Geological Survey (USGS) and the University of Guelph from 2014 to 2015 as part of the U.S. Department of Defense Strategic Environmental Research and Development Program (SERDP) and Environmental...
