    • Total sinking particle flux and content, Nd content, Nd and Sr isotopic composition, and radiocarbon content from sinking particle (from 2004 to 2007), and sediment samples (from 1993 to 2010) collected in NW Atlantic (NCEI Accession 0222212)

    Metadata Updated: March 1, 2025

    This dataset contains total particle flux and content, Nd content and isotopic composition, and radiocarbon contents in sinking particles collected by sediment traps deployed at 3 depths on the Northwest Atlantic from 2004 to 2007, and surface sediment samples collected by multicore and boxcore (by R/V Endeavor, R/V Oceanus, and R/V Knorr cruises). Among those data, total sinking particle flux and content and radiocarbon content were previously published in Hwang et al (2009) from 1993 to 2010. Nd content, Nd and Sr isotopic composition are newly obtained with a Thermo-Finnigan NEPTUNE multi-collector inductively coupled plasma-mass spectrometer (MC-ICP-MS). Here we examined the Nd isotopic composition to constrain particle transport trajectories.
