Multi-proxy geochemical and sedimentological data from 20 short sediment cores collected along the Euphrates, Tigris, and Shatt al-Gharraf rivers in the lower Mesopotamian Plain, Iraq Multi-proxy geochemical and sedimentological data from 20 short sediment cores collected along the Euphrates, Tigris, and Shatt al-Gharraf rivers in the lower Mesopotamian Plain, Iraq

This data release presents multi-proxy geochemical and sedimentological data from 20 short sediment cores (ranging 50–70 cm in depth) collected in 2003 along the Euphrates, Tigris, and Shatt al-Gharraf rivers in the Lower Mesopotamian Plain, Iraq. The dataset includes X-ray fluorescence (XRF) elemental abundances, particle size distributions, visible and near-infrared spectrophotometry...

Magnetic susceptibility, color spectrophotometry, X-ray fluorescence (XRF), and particle size data of the 82-foot NJ-GSB sediment core from Great Swamp National Wildlife Refuge, Morris County, New Jersey Magnetic susceptibility, color spectrophotometry, X-ray fluorescence (XRF), and particle size data of the 82-foot NJ-GSB sediment core from Great Swamp National Wildlife Refuge, Morris County, New Jersey

Analyses were conducted in 2025 to examine glaciolacustrine rhythmic laminations interpreted as annual layers (varves) in a sediment core collected from Great Swamp National Wildlife Refuge in Morris County, New Jersey in 2010. The dataset includes results from portable X-ray fluorescence (pXRF), particle size analysis (PSA), visible (color) and near-infrared spectrophotometry, and...

Particle size and portable X-ray fluorescence (pXRF) data from U.S. Army Base Fort Drum, Jefferson County, New York, 2024 (ver. 1.1, May 2025) Particle size and portable X-ray fluorescence (pXRF) data from U.S. Army Base Fort Drum, Jefferson County, New York, 2024 (ver. 1.1, May 2025)

The dataset documents results from particle size analysis (PSA) and portable X-ray fluorescence (pXRF) analysis conducted on a suite of sediment samples from U.S. Army Base Fort Drum, Jefferson County, New York. Samples denoted by "FD24-Sed" were collected to obtain representative samples of surficial geologic map units, and samples denoted by "FTD-WS-MW" were collected during a...

Particle size distribution of MIS 5a aeolianites across windward islands of the Bahamas (Great Abaco, Eleuthera, San Salvador, and Long Island) (ver. 1.1, May 2025) Particle size distribution of MIS 5a aeolianites across windward islands of the Bahamas (Great Abaco, Eleuthera, San Salvador, and Long Island) (ver. 1.1, May 2025)

Recent Quaternary carbonate island sediment preservation along low-latitude coastal regions, such as in the Bahamas, contain sediment sourced from adjacent marine environments during interglacial intervals. During these interglacial intervals, denoted by odd-numbered Marine Isotope Stages (e.g., MIS 1, 3, 5), sea levels are at a highstand relative to glacial periods (e.g., MIS 2, 4, 6)...

Portable X-ray fluorescence (pXRF) data from U.S. Army Base Fort Drum, Jefferson County, New York, 2023 (ver.1.1, May 2025) Portable X-ray fluorescence (pXRF) data from U.S. Army Base Fort Drum, Jefferson County, New York, 2023 (ver.1.1, May 2025)

The dataset documents results from portable X-ray fluorescence (pXRF) analysis conducted on a suite of sediment samples from U.S. Army Base Fort Drum, Jefferson County, New York. Most of the pXRF samples were collected from representative cells in a series of five portable optically stimulated luminescence (OSL) grids, here denoted G1 through G5, to constrain variations in grain size...

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...
