Atlantic Sediment Particle Flux and Isotopic Composition Data

Sediment trap and core samples provide measurements of particle flux, Nd and Sr isotopic composition, and radiocarbon content. The dataset covers sinking particles from 2004 to 2007 and surface sediments from 1993 to 2010 in the Northwest Atlantic. Data were collected by NOAA NCEI using research vessels and analyzed with a multi-collector ICP-MS.

Use Cases

• Analyzing temporal trends in total sinking particle flux from sediment traps.
• Tracing sediment sources and transport pathways using Nd and Sr isotopic composition.
• Investigating carbon cycling and aging processes via radiocarbon content in particles.
• Comparing particle composition across three different sampling depths in the water column.
• Correlating surface sediment data from multicore and boxcore samples with trap data.

Strengths

• Includes newly obtained high-precision Nd and Sr isotopic data measured with a Thermo-Finnigan NEPTUNE MC-ICP-MS.
• Provides multi-year temporal coverage from 1993 to 2010 for a long-term perspective.
• Samples were collected at three distinct depths, offering vertical resolution in the water column.
• Cross-platform presence on NASA EarthData and Data.gov indicates recognized importance and curation.

Limitations

• Column names and the exact row count are not provided by any source, limiting structural clarity.
• Sources conflict on the last updated date, reporting both 2010-09-01 and 2026-03 05.
• License information is not specified for any platform, restricting clarity on reuse permissions.
