2008–2020 Planktic Foraminiferal Assemblage Data From Subtropical Atlantic Ocean Sediment Traps 2008–2020 Planktic Foraminiferal Assemblage Data From Subtropical Atlantic Ocean Sediment Traps
Sediment trap time series studies collect data on planktic foraminiferal flux, assemblage composition, and geochemical responses to environmental variables, which are used in paleoceanographic research. This data release presents weekly-to-monthly resolution foraminiferal assemblage data from a long-running sediment trap study (2008–2020) in the northern Gulf of America (nGulf; 27.5° N...
Erodium pollen data from Morro Bay Salt Marsh Erodium pollen data from Morro Bay Salt Marsh
Presence/absence data for Erodium pollen in a sediment core taken from the Morro Bay Salt Marsh.
Multiproxy paleoecological data from Santa Fe Lake, NM Multiproxy paleoecological data from Santa Fe Lake, NM
This data release contains paleoecological records from Santa Fe Lake, NM USA. Santa Fe Lake is a small (1.4 ha), subalpine lake in the Sangre de Cristo Mountain Range of the Southern Rocky Mountains (35.79°N, 105.78°W, 3532 m a.s.l). Overlapping sediment cores were taken from Santa Fe Lake in September, 2020 in 5.4 m of water from a coring platform with a Livingstone square-rod piston...
Infiltration data from mini disks and bottomless buckets: postfire soil hydrologic and biogeochemical response and recovery in northern California, USA Infiltration data from mini disks and bottomless buckets: postfire soil hydrologic and biogeochemical response and recovery in northern California, USA
California’s wildfires are setting historic records for length, size, and severity (Safford and others, 2022, Kreider and others, 2024). These wildfires are altering soil processes like infiltration rates and carbon cycling over increasingly large areas (Staley and others, 2017; Kelly and others, 2020; Baur and others, 2024; Dow and others, 2024). In northern California, it is unclear...

Vegetation cover and surface elevation data in restored wetlands at the J.D. Murphree Wildlife Management Area, Texas, 2024 Vegetation cover and surface elevation data in restored wetlands at the J.D. Murphree Wildlife Management Area, Texas, 2024
Vegetation cover and surface elevation data were collected in restored marshes at the J.D. Murphree Wildlife Management Area in Texas, USA. Data were collected in late April and early May of 2024. Data were collected in 0.25 m² plots strategically placed along habitat transition zones between cover classes. Cover classes, listed from lowest to highest mean surface elevation, included...
Vegetation and soil data in the Canyonlands Research Center and adjoining arid, semiarid, and montane rangelands of San Juan County, Utah, USA Vegetation and soil data in the Canyonlands Research Center and adjoining arid, semiarid, and montane rangelands of San Juan County, Utah, USA
These data were compiled for upland vegetation and soil condition assessment and monitoring in arid, semiarid, and montane areas of northwest San Juan County, Utah, USA, near The Nature Conservancy's Canyonlands Research Center (CRC) at Dugout Ranch. The sampling area includes the Needles District of Canyonlands National Park, the Indian Creek Allotment of the Bureau of Land Management...
Soil data release of Open-File Report 02-277, collected on marine terraces near Santa Cruz, California in 1981 Soil data release of Open-File Report 02-277, collected on marine terraces near Santa Cruz, California in 1981
This data release represents samples collected in 1981 along a series of five marine terraces between Ano Nuevo and Santa Cruz in California as a part of a U.S. Geological Survey project led by Dennis Marchand to study soil chronosequences in the Western United States. These sequential surfaces of soils have similar key elements for development in the slope, climate, vegetation, and...
PRISM Pliocene-Pleistocene Planktic Foram Taxonomy PRISM Pliocene-Pleistocene Planktic Foram Taxonomy
Planktic foraminifera are single-celled organisms playing a crucial role in marine food webs by cycling nutrients within ecosystems. They are heterotrophic protists feeding on phytoplankton, the primary producers in the ocean. In turn, planktic foraminifera serve as a food source for a range of marine animals including fish, crustaceans, other zooplankton, and larger predators. In this...
Sub-Fossil Charcoal Particle Counts and Radiocarbon Age Determinations from a 2003 Core Recovered in a Perennial Wetland at Paixban, Northern Guatemala Sub-Fossil Charcoal Particle Counts and Radiocarbon Age Determinations from a 2003 Core Recovered in a Perennial Wetland at Paixban, Northern Guatemala
Sedimentary charcoal particle data and 14C age control measurements derived from a core recovered from Paixban, a wetland/lake in northern Guatemala in 2003
Pigmy Basin Cores MD02-2553 and PBBC-1 Foraminiferal Census Data Pigmy Basin Cores MD02-2553 and PBBC-1 Foraminiferal Census Data
Paleoceanographers use the distribution of planktic foraminifers in downcore sediment samples to estimate past oceanographic and paleoclimate conditions. In this data release, U.S. Geological Survey (USGS) scientists provide foraminiferal census data (species relative abundance and raw counts) from cores taken in Pigmy Basin (located in the Gulf of America) aboard the research vessel (R...
Predicted carbon fluxes in Lake Maurepas swamp forests under various hydrologic and salinity regimes Predicted carbon fluxes in Lake Maurepas swamp forests under various hydrologic and salinity regimes
A process-driven biogeochemistry model, Wetland Carbon Assessment Tool - DeNitrification-DeComposition model (WCAT-DNDC) was validated and applied to examine the responses of daily net ecosystem exchange (NEE), net primary productivity (NPP), ecosystem respiration (ER), methane (CH4) and nitrous oxide (N2O) emissions in the Lake Maurepas swamp forests under dry (2011), normal (2019), and...
